When size is critical, it is important to measure the steel stamp impression center to center or peak to peak on the stamp.(see photo)
Do not include the bevel when measuring. This is how all stamps are measured. The deeper it’s impressed, the larger it gets (to a point, there’s usually .010-.012″ per side in bevel). It is sometimes better to give us a length or an area you need to fit, we can determine the height needed. Our stamps are custom made to any size you require.
