A:Answer Top = 20.5" wide x 11.75" tall with rounded corners. The top has a tray ledge to hold the laptop when the top is tilted. There is a smaller tray ledge to hold the mouse when the top is tilted. The top can be locked into place flat, or levers released to adjust it to incremental tilts up to about 45 degrees. The legs can be fully extended to make the top 12.75" off the ground (level top) and can be shortened in incremental heights down to 9.25" (level top). If the top is tilted to 45 degrees the front edge is 5.5" off the ground (maximum tilted top) and if the legs are fully extended, the front edge is 8.6" off the ground (maximum tilted top). The legs stand centered on two supporting feet that are 11.25" long and one inch thick. The legs fold up like a card table for easy transport. I can put it into my carry on luggage.
