From section 902 of the ADA guidelines, the tops of work surfaces shall be between 28-34 inches above the finished floor. For children’s use (over the age of 5), tops of tables shall be between 26-30 inches above the finished floor. There also needs to be a clear floor space for knee and toe clearance and forward approach to the work station.
Our ADA desks are adjustable between more than these heights to accommodate a wider range of users.
