WA uses the familiar 150 mm boat / 100 mm PWC height rule.
However rego letter and numbers must have a thickness of 25mm. Our Font 3, Font 9 and Font 15 are available from our boat registration stickers order page

Registration numbers must be displayed on both sides of the hull in a clear, block‑style font. WA encourages owners to avoid reflective backgrounds that could distort visibility in bright sunlight. Placement must be forward of the midpoint and above the waterline.
PLEASE NOTE: If the vessel hull is not white, each digit should have a minimum of a white outline of 7 millimetres. When ordering your boat registration stickers pls leave a comment during checkout about your outline thickness requirement.
