A device for taking anatomical measurements uses an L-shaped beam, a clamp and an adjustment handle to measure the dimensions of body parts. The L-shaped beam is a rigid structure that functions as the main arm and the fixed jaw blade of a pair of lockable measurement calipers. Specifically, the L-shaped beam has a first leg and a second leg that are terminally connected to form a right angle. The clamp is a sleeved device that is slidably mounted onto the first leg of the L-shaped beam. This enables the user to slide the clamp along the first leg until the clamp is moved into a desired position. The user can then lock the clamp in place. The adjustment handle is a rigid beam that is terminally connected to the clamp. Thus positioned, the adjustment handle acts as the movable jaw blade for the pair of lockable measurement calipers.
