How to Add a Minimum Required Size for Images Uploaded by Shoppers

Last updated: April 28, 2026

If your design requires a high-quality print, you can set a minimum width and height (in pixels) for any image shoppers upload. This ensures the image won’t appear blurry or pixelated when printed.

If a shopper tries to upload an image smaller than the minimum size you set, they’ll see an error message prompting them to upload a larger file.

How to Know What Minimum Size to Use

For most print products, aim for at least 150 DPI (dots per inch) to ensure good print quality. You can calculate the minimum pixel dimensions like this:

Photo Print Width in inches × DPI = pixel width  
Photo Print Height in inches × DPI = pixel height 

Example:

  • An 8×10 inch print at 150 DPI would need at least 1200×1500 px.

Here’s a quick reference guide:

Photo Print Size (inches) MinPixels @150 DPI Min Pixels @300 DPI
5x7 750x1050 1500x2100
8x10 1200x1500 2400x3000
12x16 1800x2400 3600x4800
16x20 2400x3000 4800x6000
20x24 3000x3600 6000x7200

Keep in Mind

Setting very high pixel requirements may cause shoppers’ uploads to be rejected, especially if they’re uploading from mobile devices.
