FAQs - aspect ratio

Every image has a shape. Some are square, most are rectangular. Aspect ratio is simply a description of the image's width and height. This is most often expressed as a ratio such as 4:5, 16:9 and so on. This can express length:width or width:length, depending on whether the image is oriented to portrait or landscape.

Aspect ratio and resolution describe different things about a file. Aspect ratio and resolution are related (one describes the numerical relationship between the length and width, the other measures how many pixels per inch are available) but they are not the same thing.


Every square image, regardless of its size, has an aspect ratio of 1:1.  That means that the length of the image is exactly the same as its width. That's what we mean when we say "square".


Most photos come off the camera as some sort of rectangular shape. Common aspect ratios are 4:5 and 16:9.

Cropped images

If you crop your own images without paying attention to aspect ratio, it is very likely you'll end up with a non-standard size that will require custom framing. We are capable of printing most non-standard sizes without any trouble at all; but be aware that when you reach framing stage you may encounter some trouble with standard frames.

So what aspect ratio should I use?

That depends. What size print do you want? If you want a 12" x 12" (square) print, you need to crop the file to be square. If you want an 8" x 10", there's no use in sending us a long panoramic photo or a square photo. Common aspect ratios are below.

Common aspect ratios include:

Moving columns requires cropping
Moving rows requires 
changing resolution




4" x 6" 4" x 4.53"  4" x 5" 
8" x 12" 8" x 10.67" 8" x 10" 
10" x 15" 9" x 12"  9" x 11.25" 
11" x 16.5" 11" x 14.67" 11" x 13.75"
16" x 24" 16" x 21.33" 16" x 20"
18" x 27" 18" x 24" 18" x 22.5"
24" x 36" 24" x 32" 24" x 30"
