A method of using reflection of a laser ray (LZ) for measuring the thickness (e) of a flat mail item (1) consists in nipping the mail item by means of an elastically deformable member (3) that has a first surface (4a) in contact with one face of said mail item, and a reflective second surface (4b) substantially parallel to said first surface, and in directing the laser ray onto said reflective second surface (4b) for the purpose of measuring the thickness of the mail item.
