I'm working on an image heavy single page site and I'm trying to figure out a safe height/width ratio so I could get a rough idea of how tall the slideshow images could get if the width were set to 100% while accomodating all the page elements without pushing the "next" button below the fold. This takes into consideration the browser interface, taskbar and whatnot.
Here's what I mean: image link
I am wondering whether there are any proposed/researched/applied semi standards like the 960 grid for dealing with these layouts?
To clarify: example single page site
For my browser/screen (FF19 with menu and address bar on 1920x1080 resolution screen) the "more" button would be pushed below the fold, so I would have to scroll down in order to see it. This is what I'm trying to avoid. Obviously I could make the slideshow image very thin but that would leave a lot of blank space underneath in most cases, so I'm trying to find a useful balance, if any exists.
Cheers!
