What is the most common signature banner size?

[bliss]

Posting in this area cause the question is for my up coming signature button exchange website.

What is the most common signature banner size used on other forums and which is the most non intrusive size that would give enough information to make people intrested in them.

1: 300x20 (banner bars)
2: 88x31 (standard button)
3: 88x15 (half high button)
4: 400x100 (more then normal enough room for information)
5: 234x60 (small adsense box)
6: 468x60 (regular adsense box)

-or- add your own size.

I know namepros does not allow linked images in the signatures, but othe forums do and I would like to get some insight on which is the most common types.

The site is going to be a signature button share website. It works like a standard banner exchange, but will be for forum signatures instead of being posted on websites. Advertising everyones sites along with your own site and earning credits while your at it.

Signature Button Exchange <-- Link

I still have to pick a nice header, but all else is working petty well. I am going to be changing the exchange ratio also something like 1:8 because of the higher view rate of forums.

alot ot of large forums no longer allow any images in the signature.
Clutters up the threads.

But to answer your question prolly 6: 468x60 (regular adsense box)
