Question about gradients?

[DarknessDivine]

If I were to make a gradient for my forum like the ones used here at vBulletin exactly what is the Height" and Width" I need to make them for them to fit the catagory areas and so on.What are the sizes of the ones used here? I don't want broken or funny tiled looking gradients..
Thanx,
D.Divine:p

You can look in images/gradients to see the images used here.
