: you are right about that, they are in fact standard 88x31, I completely forgot about that size when I started a while ago ... I will change it with the next pack if I decide to embark on creating some more in the future. Thanks for the info! (I checked the size again by going to a design site that I typically check out, and yep, their button sizes were 88x31 in fact.)
Note: In AIM, I think the icon sizes are more like 40x40 or something, not 88x31. If you put in a bigger button/icon, it will get resized anyway, or shrunk.
