half inch preferably the measurement device includes at least four different fixed height measurement elements for example one inch three quarters inch one half inch and one quarter inch however it is contemplated that the measurement device can have five or more different fixed height measurement elements the measurement device is preferably formed as a fixed unitary structure for example cut from a solid block the measurement device is constructed of a rigid and durable material such as wood plastic or metal the measurement device preferably includes a flat base surface common to each of the different fixed height measurement elements the different fixed height measurement elements are then measured with respect to the flat base surface the different fixed height measurement elements are preferably arranged in a horizontally symmetrical pattern however it is contemplated that asymmetrical patterns could also be effective an example embodiment of the measurement device 10 is shown in fig1 7 the different fixed height measurement elements are depicted as a plurality of fingers 20 30 40 50 arranged at right angles with respect to each other fig5 specifically shows a view of a base surface 15 from which a plurality of widths w2 w3 w4 w5 of the different fingers 20 30 40 50 respectively are measured as depicted the base surface 15 can have a cross shape see fig4 5 with at least a one surface of each of the fingers 20 30 40 50 having equivalent surface area and with the fingers 20 30 40 50 having a length l2 l3 l4 l5 respectively however the base surface 15 can be arranged in a different shape with a different number of fingers.
