Other ways to find out your screen size (resolution)
For PCs (95/98/NT XP) Look for the little computer screen symbol on your toolbar. This is usually at the bottom of your monitor. Hold the mouse over it and it will show you the size. If this doesn't work, go to the start menu, choose 'Properties' then 'Settings' then 'Display' and look in the window for 'Screen Area' or it may be called 'Desktop Area'. This will tell you your current screen size.
For Macs Click on the apple symbol (usually in the top left hand corner of the monitor) then select 'Control Panel' then 'Monitors & Sound' from the menu. A window will appear telling you how big your screen is (also called the resolution).
