On the right you can see how the sizes will look depending on the Icon Size
setting in the Appearance menu.
A 16-pixel format wasen't really necessary for this set. At that size, too many of the distinguishing
features of each image become disolved so it was not worth it for me to process this extra format into
the icons. Even the 32-pixel size was pushing the limit for this MLS icon set, so a 24-pixel format was
also dropped.
All of the icons work well down to 48 but a few start to deteriorate at this 32
and sharpening then doesn't help much. If you want to be able to show fancy icons with greater
detail like these, then make your icons bigger by changing the Icon Size setting in your Appearance menu
to at least 48.
You can download this icon (Columbus Crew) as a free sample to test on your computer.
