What is the best adsense ad format size?

I want to know: What is the best adsense ad format size?
Please tell me!
Thanks

 

why don't you try and let us know what sizes suit your site? DIfferent site, different ad format

 

I'm running the ad on only one site with 3 format: 300x250, 468x60, and 160x600. I heard that: 336x280 is the best format, isn't it?

 

according to what google said....the best formats are: 336x280, 160x600 and 728x90.....and the worst format is 468x60.......

 

I think 728x90 is the best. In my experiences it is.

 

For me the best is 336x280

 

Hey,

You can't just say which one is the best, Just my testing it on your site you will get desired output result.

Thanks & Regards

336*280 i always best

 

I think 336x280 is a good size for ad, because it's not too wide, or too long.

 

Thank all guys. It seem 338x280 ad is the best ad size for everyone. Maybe I have to try to get a comparison by myself.

 

They are all good if placed in the right places.

 

Whichever converts the best for the specific placement on your website. You have to test to find out.
