Is there a maximum width an iframe Facebook application can be?

760 pixels

I just played with it and to the pixel 758 760 was the largest I could go with out a scroll bar.

Edit: As portman has pointed out I had forgotten about borders. Please upvote his answer.

Be careful when using 760px though, I have often found you actually get a few less than they promise. I usually shoot for 740px to ensure I don't get any scroll bars.

I solved this problem by adding public css style in application page and I got 760 px

<style>
* {
margin:0;
padding:0;
}
</style>
