a regular size is 300x200 or either ways,.. but if you want to maintain your Sig.. use a Spoiler like this:

[*spoiler] your Sig/text here [*/spoiler]

*note: remove this " * " on the spoiler.

Best example, check my sig.

sir what is the regular size of the sig?

Please, edit your Sig.. it's too big. reduce it's size.
~ I don't want to Give you a Warning or Infractions. but i hope you will edit your Sig after you have read this.

ok sir
