This wooden table base for a coffee table is 41" x 20" x 4". The base of this is 4 inches thick vertically. The four screw in legs extend another 14 inches down. This is very sturdy; it was designed to hold a larger marble coffee table top, 52 x 28 (which we put on a brass base). It could take a glass top, a granite top, a wooden top....whatever your imagination can create.
