A hands-free level for gauging structural-member orientation. The level includes an elongate frame with two side-faces and at least one main reference surface extending therealong and having a mainwidth, a level indicator secured to the frame, and a support arm to facilitate holding of the reference surface against the stud. The support arm has a proximal end and extends to a free distal end to which an end member is secured. The proximal end is pivotably secured to the frame about a pivot axis intersecting the side-faces such that the distal end and end member are movable between a storage position along one of the side-faces and a use position beyond the reference surface and stud. A coil spring is about the pivot axis biases the distal end and end member to the storage position. The end member extends from the distal end crosswise with respect to the mainwidth and terminates in a stud-engaging portion extending in a direction intersecting the plane of the reference surface. When the reference surface is against a stud surface, the stud-engaging portion engages the opposite side of the stud for hands-free holding of the level thereagainst.
