The longer the name, the shorter the height. For example, the name Christopher in our 24" wide size, font Sydney, would be approx 10" tall. But the name Chris in the same size and font, would be approx 17" tall.If you have any specific questions, please send us a message with the name you wish to customize, ideal size, and font desired.
