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 low-quality. If the background image you use is too large, the resulting certificate will take longer 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 certificates if they choose to do so.
If most 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 most of your students are in the rest of the world (Europe, Asia, Africa), 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. The portrait is the same size as 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: 1123px x 794px
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 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
Important Note: If you're unable to enable the 'HQ PDF for printing' feature after uploading an image with dimensions higher than the minimum, revert to the recommended sizes, which should fix this issue.
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, an extra image around the edges 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. Ensure 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.
