Deck Board Calculator

How many deck boards, what lengths, and screws — plus board count across the deck. Free, no sign-up.

Boards run along the deck's length and are laid side by side across its width. Where the deck is longer than your boards, rows get butt joints — stagger them and land each joint on a joist.

Screws assume two per board at every joist.
