Reply To: ?nteractive Magazine Layout size

You should design to a larger size. Very few users (relatively speaking) are on 1024×768 screens. 1280×1024 is about the low end of 4:3 screens, and the dominant sizes are in 16:9 ratios for both desktop and laptop screens. If you don't watch the user to have to scroll down, you'll be safe with a max height of 800 px, and let the width fit the aspect ratio you choose.
