What's the Best Certificate Background Image Size?

The size of the image you use for your certificate's background is important.

If the image is too small then it will make your certificate look awful. If the background image you use is too large the resulting certificate will take forever to load on a webpage and even fail to download or share on other platforms like LinkedIn. Here are the best pixel sizes to use for your certificate background images.

What Size is Your Certificate?

First, it depends on your desired paper size. Accredible Digital certificates match standard paper sizes so it is easy to create PDFs and for recipients to print their certificate if they choose to do so.

If the majority of your students are located in North or South America, you likely want to create your design as US Letter (8.5" x 11"). If the majority of your students are in the rest of the world (Europe, Asia, Africa) then you likely want to create your certificate design on A4 paper size.

You can select which size certificate design you want on the design editor, as long as you have not selected a text or image block

What Orientation is Your Design?

If you have chosen Landscape, you want a certificate that is wider than it is tall. Portrait is the same size of paper, oriented up and down.

Our Recommended Minimum Sizes for your certificate background image:

US Letter Landscape: 1056px x 816px

US Letter Portrait: 816px x 1056px


A4 Landscape: 794px x 1123px

A4 Portrait: 1123px x 794px


Be aware that these are minimum sizes, however don't make the image too large, as this will cause loading and rendering issues for your recipients.

Ensure that if your image is larger, you maintain the correct aspect ratio so that when your image gets resized on the certificate, it doesn't become distorted.

Considering High-Quality Printing?

If you want your recipients to have the option of printing their certificate at a professional printer, you will need to have a sufficiently high-resolution background image. As always, if you are providing a larger image, ensure that you maintain the correct aspect ratio in order to prevent distortion.

Recommended Sizes for HQ Printing 

US Letter Landscape: 3418px x 2668px

US Letter Portrait: 2668px x 3418px


A4 Landscape: 3626px x 2598px

A4 Portrait: 2598px x 3626px

High Quality Printing - The Bleed Area

If your background is large enough for a high-quality print, we will assume your image has a bleed area; extra image around the edges that is designed to be cut off after printing.

The bleed area ensures that your design can go right to the edges of the paper size, accounting for printers not being able to print right to the very edge of the paper. Make sure that if you want your design to reach the very edges of the page, turn bleed margins ON, and you keep specific details away from the edges of your design.
