Hope this is the right category for this. . .there's an older thread, similar subject in the same category, so I'm assuming it's okay.

I wanted to know if there's a standard poster size for a movie poster. Or if there are several sizes. I feel like 24x36 is way too big. I was thinking I need something for festivals that they might hang up at their location. Also, as mentioned on here elsewhere, withoutabox almost always requests posters and flyers as part of your online or mail-in press kit.

Ditto flyers. Some standard size for these?

Anyone? Anyone?

I see that 27"x40" seems to be a standard size, but as I said, I was hoping there was a smaller standard size. . .
