well, the max amount of characters in ur sig is 20 i think, but if you have TB prime, you have unlimited, like me!

Without TB Prime: 200
With TB Prime: supposedly unlimited >.>

Avatar size limit is 100x100, though you can upload a higher res, but it will be converted down.
Signature size is 400x100.

Signature: 200 without prime. With prime is ∞ LoL
Avatar: the best size is 100x100 (like mine)
