Image Resolution

About Image Resolution


Resolution refers to the number of pixels an image contains. You will often see resolution expressed in “pixels per inch” (ppi). The higher the resolution of an image, the more pixels it contains and – generally – the better its picture quality.


The high-resolution image on the left appears crisp and clear because it contains many pixels that capture the fine detail. The low-resolution image on the right appears blurry (or “pixelated”) because it contains fewer pixels and much of the detail is lost. Refer to the manual for your camera or phone for information about adjusting resolution settings.

Recommended Resolutions

Each product has its own resolution specifications. These specifications depend on the size of the product and the materials used to make it. Refer to the recommended resolutions for:

We automatically check the resolution of images and display a low resolution warning if an image contains fewer pixels than what’s needed to produce a high-quality product.


What Do I Do if I See a Low Resolution Warning?

  • Use a higher resolution version of your image if you have one. The original photo, as it was first taken on the camera, is always the version with the highest resolution. Use the original version if you can.
  • If you’ve cropped your image, try zooming out or removing the crop.
  • Select a smaller size for your product. For example, try a 3x6 banner in place of a 4x8 banner
  • Choose a different image that contains more pixels.
