How to Check Your Photo’s Resolution Before Printing

This post will help you make sure your photo’s resolution is large enough to become the stunning wall print you want to hang in your home.  

HOW TO CHECK YOUR PHOTO’S RESOLUTION BEFORE PRINTING

Photos on the wall are different than photos on a digital screen or printed in a small format because they are: 
  • Physically larger – Photo wall prints are simply bigger than photos on your screen or in a photo book. This means that large photo prints require photos with more pixels per inch (ppi) than smaller photo prints. 
  • Viewed from farther away – Most likely, you don’t stand close enough to lick your wall prints. You admire view them from at least several feet away. Because the distance between your eye and a wall print is greater than between your eye and a photo book, for example, the resolution between these print sizes can also differ. Wall prints often look great at resolutions lower than those needed smaller photo prints.

Step 1. Always shoot using the highest resolution

Before you start shooting, double-check your camera’s settings to be sure your photos will be saved at the maximum resolution. It’s always possible to re-save your photos in a lower resolution later (if you want to share them online, for example). But if it’s very hard to turn a low-resolution photo into a quality wall print. So shoot using the highest resolution possible – it will save you much grief later!

Choose maximum photo resolution in your camera’s settings.

Step 2. Check your camera’s megapixels

Every camera has a certain number of megapixels. Cameras with more megapixels shoot higher resolution photos. The higher the resolution, the larger a photo can be printed.
Many smart phones have cameras with 12+ megapixels and SLR cameras have even more (sometimes much, much more). In general, even cameras with 8+ megapixels can shoot photos that will look great as 24″ X 36″ wall prints. To make larger, high-quality wall photo prints, you’ll need a camera with more than 8 megapixels.
If your camera has 8 megapixels or more, rest easy – you’ll be able to print a stunning wall print! 

Step 3. Check the width and height of your photo in pixels 

A photo’s resolution is measured in pixels (not inches or centimeters). To check a photo’s resolution, you will need to check the width and height of your photo in pixels. This information is saved in the photo’s data file. 
Do you use Photoshop? If so, open the photo in Photoshop and click on Image > Image Size. Make sure the photo’s width and height are set to pixels (not inches, centimeters, millimeters, etc.) This will show you the width and height of the photo in pixels.

One way to check your pixels is with Image Size in Photoshop
If you don’t use Photoshop, no problem! On a PC you can get this information by right-clicking on the photo, scrolling down to Properties, and checking under Details for the photo size in pixels. On a Mac, when you command-click on the photo, scroll down and click on Get Info. Under More Info you’ll find the number of pixels. It’s as easy as that! 
Once you have this information, you can use it to check the maximum print size for that photo.

Step 4. Calculate the maximum print size based on the photo’s pixels 

While small printed photos are generally printed at 300 pixels per inch (ppi), for larger prints (like wall prints), there’s more wiggle room in the number of pixels needed because of the distance at which they will be viewed. (We’re assuming you will stand at least 12 inches from your wall print when admiring it!) 
Fun fact: Billboards are often printed at resolutions as low as 12-15 ppi!  Because they’re viewed from far away, they still look great even though the resolution isn’t very high. The same principle applies to large wall prints.
For photo prints that are 24″ by 36″ or larger, Xpozer recommends a minimum of 80 ppi.  
This photo has a 99 ppi resolution so it is big enough for a 60″ x 40″ wall print.
With Photoshop you can easily check if your photo can be printed at the size you want. Follow these quick steps:
  1. Go to Image > Image Size
  2. For Width and Height, choose Inches (not pixels this time)
  3. Unclick the “Resample” box
  4. Fill in the width and height (in inches) for the desired print size (ex: 40″ x 60″)
  5. Check the resolution number (it will adjust automatically based on the width and height you put in). If the resolution is higher than 80 ppi, then your photo has a resolution that’s good enough for quality print at the size you want! 
  6. Always double-check your entire photo at 100% size.
Don’t use Photoshop? This handy chart shows how big a photo you can print based on your camera’s megapixels (assuming that you shoot at maximum resolution). 
Checking your photo’s resolution is an essential part going from digital photo to perfect wall print. By using the above tips, you can be sure that your photo’s resolution is high enough for the big photo print you want in your home.
