What are the sizes used for the different options?

Question

When searching on Google Images, under "Search Tools" there is a dropdown for "Size". The options in this list are:

• Large
• Medium
• Icon
• Larger than...
• Exactly...

While the bottom 2 are fairly easy to understand, the other 3 are fairly subjective. What sizes are included in the "Large" option? What sizes are considered "Medium"? How small before an image is considered "Icon"?

Answer 1

I couldn't find the information anywhere, and digging through the JavaScript code didn't help me much either. However, from experimentation it seems:

• Large: All really large pictures. Smallest dimension I found is 900 x 900 pixels, but I've seen pictures with width/height of 500 or so pixels (they were balanced, however, with a height/width of 1k+).
• Medium: Includes some of the "Icon" images and scarce "Large" images (i.e. 1920 x 1080 px), but generally anything in the range of 300~500 pixels (although very frequently higher).
• Icon: Ratio is always 1:1 (width == height). Largest dimension I've seen is 512 x 512 pixels.

I believe it goes by the area of the image, but it's nowhere to be easily found.
