A measuring fixture includes at least one carrier unit for accommodating at least one work- piece to be measured. The carrier unit includes a carrying cell and a datum plane. The carrying cell is adapted for carrying the work-piece and has a carrying surface adapted for contacting a bottom surface of the work-piece. The datum plane is outward extended from the carrying cell, the datum plane and a top surface of the work-piece orient in the same direction, there is a predetermined height difference between the datum plane and the carrying surface, and there is a measurable height difference formed between the top surface of the work-piece and the datum plane, whereby the thickness of the work-piece is calculated to the summation of the predetermined height difference and the measurable height difference.
