Standard Web Digital Image Sizes

Apr 23, 2008

What size should your photos be when posting them to the web?  What are the common standard digital photo image sizes? 

Every site I looked at had different size images, but some common themes did emerge.  240 x 160 pixels was a very common small format. Larger images were typically around 460 pixels wide.  If you make your images larger than 460 pixels, most layouts in most blogs or site designs will have some difficulty fitting these sizes into the layout.

My Preferred Image Sizes

  1. Very Large 800 pixels
  2. Large 500 or 520 pixels
  3. Medium 460 pixels
  4. Medium-Small 320 pixels
  5. Small 240 pixels
  6. Thumbnail 100 pixels
  7. Square Thumb 75 pixels
