I guess I didn't pay attention to the dimensions of this desk because once we constructed it (which took several hours) it was much smaller than I expected. It's way too small for our 11-year-old son, but he's the one who put it together so he was determined to make it work for his room for at least a year. It's a good quality -- sturdy, heavy and able to hold up to the abuse of children. It's just much smaller than I expected.
