What is the most suitable size for profiles?

it depends? I make mine 1200 px wide x 1000 px tall and use a repeating bg because i always have a little space on the right.

I always use 1000px width and 600 - 800px height, depending on the layout. Since 1024x786 is the common resolution this works fine. Though on a widescreen it looks a little lost, so it's important to fill the right space, like Marzipans said ^_^

Only thing I hate is when layouts are made for widescreens, because that means side scrolling XD

Thanks :3

I usually make mine 790x590. Although practically noone uses 800x600 res anymore, I just find it easier. Plus side scrolling is hella annoying.

Standard maximum width for webpages is 960px. I usually make my profiles about 600px in height, but the height doesn't really matter as much.
