We have twin boys.  Our boys are 7 years old and average to tall.  We ordered two blue desks.  The desks fit them perfectly.  With the way that they grow this desk will last them approx 3 to 4 more years.  Love the desks.  Very easy to put together (although putting two together took me one really long day).  We were missing one screw for the chair.  Be sure to check the inventory before starting.  Really an amazingly sturdy desk.  Solid!  Would absolutely buy it again.  I may buy one for my Granddaughter too.
