Main table can be adjusted to several specific angles - see photos.
Sliding side table does not go completely under main table so width would require about 46-1/2 inches.
Main table depth is about 24".
entire structure is 24-1/2" from floor to main table top
EDITED: the way my wife had it set up was 24 and 1/2 in from the floor. The height from the floor is adjustable to seven different positions by two knobs. The tilting of the table is limited to seven specific positions from Flat to nearly 90°
