An apparatus for checking the overall lengths of workpieces or the lengths of portions of workpieces, particularly shafts or the like, includes a base in the form of a profiled rod (12). The base has two clamping faces (18, 20) which are oriented at a right angle (22) to one another and to the workpiece (14) to be checked. The base has T-shaped grooves (24, 26) which open onto the clamping faces (18, 20). Each of the clamping faces (18, 20) is provided with a respective clamping strip (30, 32) which is guided longitudinally in the respective T-groove (24, 26) by a respective protrusion (29) and which can be fixed by screws (31) in any desired position on the respective clamping face (18, 20). The clamping strips (30, 32) can be equipped with measuring devices (34), for example measuring sensors, and/or with supporting elements (36). The workpiece (14) may also be clamped into spindle sleeve mounts (46) which are mounted via the T-grooves (24, 26).
