About Photo Enlargement Printing and Digital Photo Formats
Digital cameras come in a variety of default image aspect ratios, which is the ratio of the
photo’s width to height. This ratio is based on the full frame, original photo that the camera
produces. The most common aspect ratios for digital cameras is a 4:3 and 3:2 ratio. Some newer
digital cameras can have as many as 5 different aspect ratios to choose from including –
4:3 / 5:4 / 3:2 / 16:9 / 1:1.
In our print size and price listings, we assigned a format type to each print size:
A Format – B Format
These designations mean the print size is best suited for digital photoswith a given image aspect ratio, for the least amount of photo cropping.
A Format – Best suited for digital photos with a 4:3 aspect ratio.
Applies to most typical “point and shoot” compact digital cameras.
Generally, if you frame the shot with a view screen on the back of the camera instead of thru the viewfinder and lens, you have this type camera.
B Format – Best suited for digital photos with a 3:2 aspect ratio.
Applies to most SLR digital cameras. These would be more advanced, higher priced cameras where you frame the shot thru the viewfinder and lens.
Below is a simple way to figure out the basic aspect ratio of any digital photo.
- Find the pixel dimensions of your digital photo file or the digital photo size in inches.
- Look for the image size in a photo editing application or right click on photo properties.
Note the pixels or inches width and height numbers.
- Divide the larger number by the smaller number.
- A 1.33 (or close to this number) means you have a 4:3 aspect ratio digital photo.
- A 1.5 (or close to this number) means you have a 3:2 aspect ratio digital photo.
If you place a print order and your photo requires photo cropping for the print size ordered,
we ALWAYS send a sample of the cropped photo for your approval before printing the order.
You can see how photo cropping may be an issue from the Two examples below.
Both photos have the same height (180 pixels), showing the width difference of the 2 aspect ratios.

So…what is the aspect ratio of the digital photo you want printed?
If you don’t already know the aspect ratio of your digital camera, you could look in the owners
manual where the aspect ratio will be provided in the camera’s specifications.
If you do have a wider format digital photo and absolutely DO NOT want any cropping of the photo,
but absolutely have to print the photo on a standard format print size because of a frame you
want to use, there is another option we offer our customers.
Cross Format Composite Prints:
With this printing option we can take the uncropped full frame wide format photo and place on a
standard format print size with a simulated matte area around the original photo that makes up the
difference in image and print aspect ratios. Read more about Cross Format Composite Prints here…
