70x70 is about the perfect size. 100x100 would look a little bit too big, and anything below 70x70 is too small so it's a good medium.

I'd have to disagree. 70x70 is small. A good medium would be like 85x85 if we were to settle on a size between 70x70 and 100x100. Personally I think 100x100 is perfect. But, again that is just me, I'm used to the 100x100 size so the 70x70 may just come off incredibly small to me.
