Sorry it took me so long. It is 25" wide by 19" high by 17" deep.
On the width there is about a 1/2" lip that runs out from the sides parrallel to the front on both the right and left side( I had to cut these off because I had already built the cabinet.
The depth and height are also a little difficult to measure since the metal frame that holds the glass and electronics holds the moniter at a slight angle.
I am very happy with mine. For the price it was awsome.
