Photo Resolution: Sizes Needed for Printing Your Images

how much resolution to print?

Resolution test strip. The original image portion used was 300 pixels per inch (31mp Hasselblad art capture). Each test was downsampled from the original and printed on photo paper at the same physical size. There is some loss of quality between 300 and 144 ppi but barely perceptible. Below 144 we deem too soft or blocky if you are walking up to the image.

We are often asked what quality an image needs to be for printing. This is a great question, because sending a low quality image will result in a disappointing, low quality print. Image quality includes many factors of course, from composition (the way you set the image up if you shot it), to color choice, lighting, etc. These are really important factors when capturing original artwork, and that’s why we offer professional capture services. But here, we want to discuss the size and resolution of your images. Size isn't usually an issue if the image is to be printed in a memoir but a significant factor in a 60"x40" canvas. Let’s assume you’ve taken a fabulous image, and are just looking to make sure it doesn’t appear “blurry” or “blocky” when printed. How can you be sure it will print crisp and clear?

One SIZE Does Not Fit All

Image size is the most important factor for large prints. In the most simple terms, is the image you are giving us to print large enough to fill the space you want it printed on? If it is not, it will need to be stretched or “blown up” somehow, and that always results in quality loss.

example of images sized correctly and stretched beyond acceptable size

The good news is, if you follow some basic guidelines, this should never be an issue for you. It can be very, very simple. We’d like to start with the simple, which will apply to most of you, then offer some more specific help for more specific situations.

The Really Good News

Here is the really good news folks;
If you have bought a digital camera in the past few years, and you have taken your images at the highest quality setting of that camera, you images will print just fine.

Too easy right? Let’s look a bit closer. Any camera with a good lens, good sensor, etc, that is rated at 5 megapixels or more can give a great 8 x 10 inch print, and even a decent quality 16 x 24 inch print. The 16 x 24 inch print won’t look as good when you are standing 1 inch away from it, true. But at a comfortable viewing distance, it will be just fine, even from a 5 megapixel image. Even today’s cell phones offer cameras with 5 megapixel cameras! Just make sure you are taking the image at HIGH QUALITY setting on your camera. The file format of TIFF is usually best for us, but we can also use high quality JPEG or JPG images.

Hang on  Megawhatsels?
Defining Some Terms

You got me – I said that you wouldn’t need to get complicated. And you’re probably right. Let’s review that good news; “If you have bought a digital camera in the past few years, and you have taken your images at the highest quality setting of that camera, you images will print just fine.”

This is true most of the time. But if you have a special situation, or just want to learn what’s going on “behind the curtain”, some basic understanding of terms doesn’t hurt. Let’s get to the terms first, and if you prefer you can skip to those “special situations” below.


What really matters for printing an image is it’s size. Digital images are measured not in inches, but in pixels. That is, the amount of individual digital dots of color it takes to build the image on a screen. A 10 megapixel image would have 10 million of those pixels (megapixel = million pixels). The way you get at that 10 megapixel number is similar to calculating the square footage of a room. Width x Height. So a 10 megapixel image could be 5000 pixels wide by 2000 pixels high, for instance (5000 x 2000 = 10 000 000 pixels). It could also be 3300 pixels wide and 3000 pixels high (3300 x 3000 = 9,900,000 pixels – rounded up to 10 megapixels).

Megapixels are important, but not as important as the electronics store salesman would have you believe. Why not? Because buying the best available is not wise, unless you need the best available. Buying what you need for your uses is what counts. We have seen images that had significant resolution but were grainy and flat when printed at the size requested. In this case sensor size was an issue.

ALL cameras made today have more than enough megapixels for common printing situations (and yes, that includes large canvas prints). You’ll have a hard time today buying a new camera with too few megapixels for a decent size print. Really. 10 megapixels is a common rating, with 18 megapixels and up becoming standard. Those are plenty big images folks. 

Tip: When buying a new camera, don’t focus on megapixels. There are enough. Focus on other factors that effect the visual quality of the images you’ll be taking, like the quality of the lens, performance in low-light (if that matters to you), color quality, image stabilization, handling, etc.

Pixel Dimensions

When we are asking for a certain size of image, we are asking for it’s pixel dimensions. That “3300 x 3000” number. When you provide us with that number, we can calculate how large the image can print at the settings we use on our printers here at PageMaster.

If an image is larger than the minimum dimensions we need, there’s no problem. If it is smaller, it still may be OK (if you cannot retake the image), but there may be some quality loss issues. If an image needs to be re-sized, it’s better that you let us re-size it for you here than do it at home, as we can do it quickly with the least quality loss and we know the best settings for our print environment, such as the PPI we are looking for (minimum of 144 PPI, 240 OK, 300 best) at PageMaster.

4000 x 3000 at 72 ppi

A 4000 x 3000 image from your camera is probably expressed at 72 ppi (standard monitor display resolution).

4000 x 3000 image at 300 ppi

The same 4000 x 3000 image at 300 ppi is 10x13.3 for print. For wall viewing distances the image would be about 21x28 at 144 ppi.


These two terms, DPI (dots per inch) and PPI (pixels per inch) are often used interchangeably, but they are not the same thing.  We’ll use PPI here, but know that some older programs may use DPI to define it’s “resolution” for an image. We use PPI because it actually tells us most directly how many pixels will be printed on each inch of paperPixels per inch. It’s how we determine the ideal pixel dimensions needed to print your image on a certain paper or canvas size. DPI is used to measure printer resolution and you need many dots to faithfully reproduce a pixel.

An example may help. Let’s say you want to create an art card of your latest photograph. Let’s assume the card is going to be 4 inches by 6 inches. At PageMaster, we work with a minimum of 240 pixels per inch (PPI) for these art cards. So, for every inch of printed space, we should have 240 pixels of image data to get the best results. This requires simple multiplication. Let’s start with the width of 6 inches. Multiply that by 240 and you get 1440. The image should be 1440 pixels across. The height? 4 inches x 240 PPI = 960 pixels. The image you provide us should be at least 1440 pixels by 960 pixels for a 4 x 6 print. We know this because we want an image with a minimum resolution of 240 PPI.

So, what is the megapixel count of that image? Hold on to your seat … a whopping 1.4 megapixels (1440 x 960 = 1382400 pixels = 1.4 megapixels). Your cell phone camera can likely do that folks. That’s why we didn’t want you to sweat the details. It’s not that the details don’t matter, it’s just that the details are most likely fine.

Let’s try one more example, at a larger print size of 11 X 17 inches.

11 x 240 = 2640
17 x 240 = 4080

Pixel dimensions required = 2640 x 4080 for an 11 x 17 print.

Megapixel count = 10.7

Again, almost any camera sold today will give you 10 megapixel images.

Photokaboom offers some great calculators for doing just this sort of thing, which you can access here. The site as a whole has many tips you may find useful for digital photography.

Viewing Distance

You can see that we are already needing some fairly large images for a 11 x 17 print, but all that really means is that the print will look as clear as the file itself when you put it right up to your nose and stare. Of course, you don’t do that. To take in the whole image, you sit back a bit. The larger you print the image, the further away you will view it. Because no one looks at 20 x 30 inch canvas print from one inch away, you can get away with even smaller pixel dimensions in your file. It’s true that it won’t look perfect up close, but it can look surprisingly good from a comfortable viewing distance, even if your file isn’t quite large enough. I once printed a 3 megapixel file on a 20 x 30 poster and, hanging in my living room, it looked perfectly clear. Next time you go for a walk, step up really close to a billboard and witness the magic of viewing distance. Chances are that billboard will look very blurry up close. Driving by, of coarse, it looks fine.

File Formats and Compression

A file format is the way your file is packaged to be read by computers. More simply, it refers to the extension – the text after the dot – in your filename. So “house.tiff” would be a TIFF file. “house.jpg” would be a JPEG file (these can have the extension of either .jpg OR .jpeg). We use TIFF files internally and high quality JPEG files when file size matters.

Image file sizes can be huge and there are two basic ways to reduce the size. Lossless and Lossy. Lossless methods reduce file size without changing the image quality. Lossy formats do reduce the image quality.

Each time you make a change and save a JPG file you will loose a bit more. The quality level you choose when saving and the number of changes are important. You can end up with an unusable image even with high resolution. Work in a lossless format and use JPG for the final files when size matters.

TIFF and PNG formats use an algorithms and are lossless. Enabling compression in a TIFF file will generally reduce the size by half. From a risk perspective a damaged compressed file may unrecoverable whereas a damaged uncompressed TIFF file will have missing bands. LZW is our default.

High end digital SLR cameras will take “RAW” format photos. These are great for you, because you can have finer control over the colors, sharpness, etc of the photo in a photo editing program that supports RAW file formats. RAW file editors are generally nondestructive – your changes are rendered on export from the original with no quality losses. RAW files are not great for us however, because we will likely get the unedited version of the image, which may lack some enhancements you have made. If you do use a RAW editor, like Adobe Lightroom, Apple Aperture or ON1, please export your images as JPG if e-mailing or uploading, or TIFF if sending on a disc or USB stick, before sending them to us or other service provider.

Special Situations

You want something really big

Large canvas prints

Photographer Bruce Deacon and client with canvas print at PageMaster. Bruce's work is available on our store.

If you want to reproduce an image on a really big scale, let’s talk. Our 12 color wide format printer can print 44" wide (we do large canvas reproductions and fine art paper prints), but there is a limit to sizes that we can print. A simple laser test print is the best indication of if your image will handle the size. Once a size is determined, we will look at the ideal pixel dimensions for your file and may discuss factors like viewing distance with you if needed. 

You’ve cropped your image

This is the big “what if” that could very well invalidate that simple rule we mentioned off the top. Let’s say you took an image of a beautiful Banff mountain, but there is a bear-safe garbage can just on the right edge of the image. Photo editing software (and even many cameras) will allow you to crop an image, selecting just a portion of it and erasing the rest. This is like digitally trimming pieces of the file off. Because you are cropping away some of the image, the image is going to get smaller. A 10 megapixel image is only 10 megapixel image if you use the whole thing. If you crop away 20% of that image, it is now an 8 megapixel image. This will likely not cause problems in most situations, so long as you start with a large file (pixel dimensions) and use most of the image in your final crop. If you crop one face out of a whole crowd, however, the image of that face alone may not be large enough to print at a decent quality.

Your image is from the internet

If you’ve got an image from the internet, and it is not made specifically to be printed, it will likely print poorly at larger sizes. Without getting too technical, an image 1000 pixels wide and 1000 pixels high takes up much more space on a screen than on a high-resolution paper print. Respecting copyright and supporting creatives is important. Just like you want your work to be acknowledged and paid for (so you can create more great work), treat others with the same respect.

Most stock photography websites provide high resolution images suited for printing, but images that have been found elsewhere on the web are likely not good candidates for print.

Your image was taken at a low quality setting

You now know how to get the right images from your camera going forward, but what if you have an older image that you took before you became such an image expert? Unfortunately, there is no way to make the image larger without losing some quality. There are some neat tricks we can try, but if the image size is too small, we cannot guarantee a magic bullet solution. That being said, it’s still worth a try. Contact us with your questions.

You are buying a new camera. What should you be looking for?

Let us repeat – you can virtually ignore the megapixel buzzword. It matters, but on most cameras sold today, you’re well covered with a number of 10 or even higher. What you should be looking at is how the camera will perform in the situations you will most often be using it (lots of low-light photos, for instance?). What is the quality of the lens? How much zoom is provided (ignore digital zoom – it really does nothing but crop your image in the camera, making it a smaller size image)?

If you are going to be doing photography seriously, taking and printing a lot of images, and selling those images, we encourage you to get a Digital SLR (single lens reflex) camera. The investment may be a bit higher, but the flexibility and image quality (not image size) more than makes up for the price difference. These are the big black cameras with lenses that screw of and can be changed. These cameras work much like the SLR cameras of the past, focusing on photography basics like aperture, shutter speed, ISO light sensitivity and more. These basics are invaluable for you to learn, and you can get a lot of help online (Google is your friend), or by taking a low-cost photography course in your city (here in Edmonton, courses are offered by the City Arts Centre, among other places).

If I’m taking family photos and the family wants to be able to print the pictures on a 20 by 20 canvas what settings should my camera be on and what file should I be using once I send them to her? TIFF or JPEG

    Dale Youngman - a few months ago Reply

    Hi Amanda
    Use the highest and most square aspect ratio (if there is a choice). You will be cropping quite a bit off the sides if you are printing 20×20. For close viewing you want 300 ppi which is 6,000 pixels but 2,800 should work well on canvas. JPG is smaller to transport but use the highest quality setting. Also ensure color management profiles are embedded (usually the default). JPG loses quality if you make a change and save, so work in tiff, raw or photoshop/on1/photopaint/lightroom and just save once in JPG. Our price on standard 3/4″ bars is about $90 CAD.

      Hello, Dale… I have a question. I want to print a picture in a square of 11 inches *11 inches. My photo has a width of 4586px and a height of 4000px… Is this resolution ok for that size, or I need to change the resolution?



        Dale Youngman - a few months ago Reply

        Hi Daniel
        Resolution is fine (you could downsample the copy you send to 300ppi) but your aspect ratio isn’t OK.
        To print a square image without distortion both dimensions would be the same (3300×3300). Part of the image width will be cropped.

Hi there!

So, I make digital art, and was needing to print something out big.

Normally I draw on 1900×1600 pixels at 350 dpi.

What size would that “normally” print out to, if those pixels were converted to say, inches, and would I be able to stretch/expand/enlarge it without too much pixelation, to say a size 36×48 inches?

Thank you for your time!

    Dale Youngman - a few months ago Reply

    Hi Rose
    At the best quality only 6.33 inches on the long edge. Quality should be OK at 13.2. At the full 48 inches you have less than 40 pixels per inch which you will definitely see. Upsampling may work, it does depend a bit on the image. Do a test strip.
    BTW vector art like CorelDraw and Illustrator is fully scalable.

Giorgi - 6 months ago Reply

Hi, let’s say I have two files of the same image, one TIFF (27.9MB) and one JPEG (4.18) , both 3519 x 2775, DPI 300. which one will give me a better result if printed on a large format 17×22 paper ?
I understand that in both case the printed quality will worsen, PPI will decrease to 150, but does TIFF have any advantage over JPEG?
and another question – which one is the safer way to increase the document size in Photoshop, “Resample image” Unchecked or Checked?


    Dale Youngman - a few months ago Reply

    Hi Giorgi
    As long as the JPG file has been saved with the highest quality you shouldn’t see any difference. However, each time you make a change and save a JPG you do loose definition. Use JPGs for the web and sending when size matters, and use TIFF locally.
    If you have the resample image choice off in PhotoShop you are changing the printed dimensions without changing the actual pixels (screens often ignore the dimensions and just map pixels). I start with the button unchecked.

    Hi Sean
    In my tests, I found image quality dropped off visually at 144 ppi. 4096/144=28.44 so over 28 could be a bit of a stretch. BTW 4096×2048=2/1 so at 28″ wide you would be 14″ high.

Hi, I am creating a banner on vinyl. It will be 33.5″ x 86″. I am using photos off of Istock. Most of the photos I find are between 2000 – 4,500 px and 300 dpi. My question is will these images be too small on this size banner? If so what pictures and where should I be looking for them instead?

    Dale Youngman - 6 months ago Reply

    Hi Alicia
    For background images at a distance you can get away with less resolution, as long as the type is sharp. Recommended resolution for a billboard is 100 ppi and would be fine for a background on a banner. 4500/86=52ppi so you would want to do a test print. Newer cameras have higher resolution but is the right photo available? Possibly you can repeat a mirror of the image, or upsample in ON1. .

Hi – I am putting together a college art portfolio and the image files must be 1000 x 1000 pixel resolution min and 2000 x 2000 pixel resolution maximum. All images saved as maximum quality .jpeg. The application is on line so images will be uploaded into the application. I am using a Canon EOS Rebel T1i. What image recording quality setting should I use to take the photos. I will use Photoshop to compress images. 2nd option is to use my Iphone 8 but from what I have read – a digital camera is preferred. Thank you!

    Dale Youngman - 8 months ago Reply

    Hi Sharon
    Do the images need to be square or can they be 1000 x 2000 pixels?
    If they were square the shorter dimension is the one to watch. I would shoot raw or the best setting and then down-sample in Photoshop.
    Are you photographing your art? Or is the photography the art?
    For art: a grey card will help with color balance and a longer lens and more distance will reduce key-stoning.

My question or doubt is that I have a good camera set for highest quality pics. Most of the pics are 8000-12000 KB, dimensions are easily over 4000 x 2000 pixels, and yet, the ppp (I guess its ppi in spanish?) shows 72ppp. If I understood your blog correctly, the ppp should be very much higher for printing. If I have a good camera, use highest quality, and have huge pixels, why is my ppp so very low?

The next question would be, if I want to print a pic on foam at 60 x 80 cms for example, for printing and exhibit, which of these numbers should I be looking at, and which would be the correct figure?

Thanks for your help and for your posts! Oscar

    Dale Youngman - 9 months ago Reply

    Hi Oscar.
    I have added a couple of screenshots to the post that help explain how the image size and output PPI relate. The PPI is how dense the image is rendered.
    For the second question: Most programs will show both pixels per inch and pixels per centimetre. Three-hundred pixels per inch is optimal, so don’t down-sample more than 300 if you have a large image (always keep your original and work on a copy). Resize without resampling the image to not change the actual file size – just the output size.
    I hope this helps.

    Dale Youngman - 10 months ago Reply

    Hi Mark.
    From a straight resolution perspective the image should be good to print. Lighting, perspective, color balance and grey balance are important.
    The image dimensions you provide yield a 40 x 29.9 image at 124.2 pixels per inch. (4984 / 40 = 124.6 and 3726 / 124.6 = 29.903).

Can I make a 4 foot by 6 foot photo from 5265 x 3510

    Dale Youngman - 10 months ago Reply

    Hi Barb
    You are at about the same resolution as a standard monitor. I have prints that look good in this range, especially with older cameras. We do up-sample if below 144ppi for printing. A portion test-printed is always a good idea before doing a really large print. Our wide format printer has a maximum width of 44 inches and generally you want some border for framing or stretching. Fill out the contact form or drop in and we can get started.

Thanks so much in advance for your time,


    Dale Youngman - 11 months ago Reply

    At 5090 you have a good sized image to work with. At 144 pixels per inch you are at 35.34 inches on the wide side (5090 / 144). Below 144 we would upsample as you will notice the softness. If everything else in the photo is good you can get a 60 inch wide image. On our page about photo reproduction there is a copy of a 3’x5′ along with the original in the left column (on desktop). It was taken with a 31 mp Hasselbald on a tripod with controlled lighting. In this case the artist wanted the image punched up a bit. On the photo capture page is an image with a 9 foot by 6 foot reproduction as a triptych.
    An additional note about copyright is in order. In Canada, the actual right to reproduce a work is retained by the artist unless explicitly transferred. Purchasing a painting does not transfer the right to copy or publish it.
    I will get an article on Beyond Resolution up soon as there are other factors in creating great prints.

I have a gallery that wants to exhibit some of my photos. They want 30×40 metal prints.

I took the photos with a Nikon D3 and it’s a full frame 12mp camera. I cropped some of them just a little. Will you be able to print these sizes for me? I’ve never displayed in a gallery so I’m not sure if 200 dpi is enough. Please advise

    Hi Jay.
    It is great to hear that you are getting exposure for your work. 200 ppi is good and barely perceptible from 300. Currently we don’t have a flatbed wide format printer which is required for printing directly on metal. We have metallic photo paper but that is not the same.

    Hi Nahidhasan
    If you have a small image and crop it, it will be even smaller. We would run a test print at actual size to see what it would look like before running canvas or fine art paper. The viewing conditions for the final piece also affect how much you can enlarge and still look good.

I have a file with 300dpi, 3582 x 2388 pixels, 4,772 KB. I would like to print it on canvas for hanging on the wall. I understood that the ideal print size will be 8.5″ x 11″. However can this file be printed on a larger canvas (for example up to 11″ x 17″) without significant loss of quality. The photo is black and white if that is of any significance. In order to print it larger and keep the quality what do I need to do?
Also I would like to ask what colour range the file need to be – CMYK or SRGB?
Thank you in advance for your reply!

    Dale Youngman - last year Reply

    In our tests, 144 pixels per inch looks good at normal viewing distance without any additional processing. That gives you a 24″ wide image. If you want us to print it larger than 24″ wide we can up-sample here with ON1 resize and test print before running the full canvas.
    For color space: It is best to tag, not convert. Don’t use CMYK for digital printing, especially for canvas. You won’t get the best color. Our canvas printer runs 12 colors and you would be losing much of the possible color by converting. Even on our 4 color digital press we use for cards, using an offset based CMYK profile will lose color. Leave as RGB and keep it in the largest gamut possible.

I have a family member that wants to print a sticker that is 36×48 I used an image size on my camera of Medium 3696×2456 that is 9.1M. How should I calculate this so he has a clean image?

    Dale Youngman - last year Reply

    Hi Megan
    For a print 4 feet by 3 feet you would want to use the high setting on your camera. A standard monitor is 72 pixels per inch and you are in that range depending on which dimension you go with. (3696 pixels /48 inches = 77 pixels per inch) or (2456 / 36 = 68.2 pixels per inch).
    How close you are to the image is also a factor. At a reasonable viewing distance this will look OK. If you move in to reading distance you will notice some loss of quality.

    Dale Youngman - last year Reply

    It depends.
    Based on our tests there will be a visible loss in quality viewing from arms length at resolutions lower than 144 pixels per inch (ppi). The pixel dimensions of the file are what is needed to calculate the resulting ppi. An image of 300×300 can be 1×1 at 300 ppi or 6×6 at 50 ppi. Standard screen is 72 ppi and standard print is 300 ppi.
    When there is doubt we scale the photo to the desired size and print an inexpensive laser print of a portion of the image to visually check.

A 20×30 print at 200 pixels per inch requires 4,000 x 6,000 pixels after cropping. For large reproductions you may want to look at a drum scanner.

I am a film photographer and when my film comes back from the lab, I scan it on my printer to convert it to digital. How many pixels are in my 35mm conversion? I’m able to print up to 13×19 photos on my Epson and never worried about pixels and dpi…of course I print everything at the highest resolution I can manage, but I hate the tech side of it. However for larger format prints, let’s say 20×30, I know I need to manage my megapixels…how many pixels do I need? I’m old-school and hate the digital world I find myself in. Film rules!

    Yes, the numbers it can be confusing. Printer resolution (dpi) and pixels per inch (ppi) are different. Expect printer resolutions of at least 1200 dots per inch for good tonal graduation, and, yes, use the maximum settings for all fine-art work.
    It is best to get all the resolution you will need when you scan. An image at 1200 pixels wide will be 4 inches at 300 ppi (print) and 16.7 inches wide at 72 ppi (screen). Viewing distance also affects how sharp an image presents but so does the overall quality of the image. We have a 37×62 print on canvas I took with a Canon XTi in our meeting room. We did up-sample it to 144. We have down-sampled and tested a number of resolutions and between 144 and 300 pixels per inch is not significantly noticeable and have established 144 as a base line with 300 as optimum. A quick digital press print of part of the image is a great way to proof before doing a large canvas.

The optimum resolution is 300 pixels per inch (31 mega pixels) but you will get good results from 144 or less. The overall quality of the photo and JPG compression are also a factor. We have a 3 foot by 5 foot image in our meeting room that we printed on canvas taken with a Canon XTi that looks fantastic. Don’t upsample, except if exporting from RAW, just send the best image you have.
Our upload page is at You can choose canvas, photo and fine-art papers. It is in final test stages and any feedback is welcome. You can also email hello at pagemaster dot ca.
