How much fiberglass cloth do I need to build a surfboard?

The amount of fiberglass cloth required depends on your surfboard’s size, glassing schedule, and whether you're accounting for waste and overlap. For a typical 6'1" shortboard with a standard 6/4 oz deck and a single 4 oz bottom layer, here's what you'll need:

• Deck: One layer of 6 oz + one layer of 4 oz
• Bottom: One layer of 4 oz

Recommended yardage (includes ~1 yard buffer for waste and trimming):

• 6 oz fiberglass cloth: 3 yards
• 4 oz fiberglass cloth: 6 yards

These estimates are based on 30" wide cloth. If you're using wider rolls (like 38"), you may use slightly less.

Tip: Always round up to avoid running short mid-project.
