3 Inch Tall Boat Registration Numbers

Typically you will find most states require boat registration numbers to be three inches tall. Not only that they should be of a block lettering font for fully comply in a contrasting color to the hull. We give you the flexibility to create compliant boat registration decals using our online design tool. In a block font 3 inch letter will consist of measures from the base of a capital letter to the tip or top of the letter. Using this metric we scale your design to the proper size when outputting to our vinyl cutter to ensure it meets the 3 inch requirement.

Use our designer to design boat lettering, registration numbers, hail port names , and anything else!
