I had a quarter of an inch to spare and hope that the dimensions provided in the description were accurate.  They were and it fits perfectly in the very small space I have in my daughters room. There were not many desks that fit within our 30 inch requirement and this one not only fits it looks fantastic too. It was easy to out together if you follow the instructions methodically. If you don't you may end up lost and back tracking to previous steps.  It is sturdy and well made for the money.  I like the "X" styling and the structural design makes it sturdy and "current" with simple, classic lines. Couldnt be happier.
