CALCULATOR

How to use the deck calculator

This calculator tells you how many linear feet of boards you need to cover an area. Use it to plan a deck or any other wood surface.

1. Pick the board size you plan to use, such as 1×6 or 5/4×6.
2. Enter the area of your project in square feet. To get it, multiply the length by the width. A deck that is 12 feet by 16 feet is 192 square feet.
3. Click Calculate. The result is the total length of boards you need, in linear feet (LF).

What is a linear foot?

A linear foot is one foot of board length, no matter how wide or thick the board is. Decking is often sold by the linear foot, so this number helps you plan your order and compare prices.

Before you order

• Wider boards cover more area, so you need fewer linear feet.
• Plan for a few extra boards for cuts and waste.
• The result is an estimate. Our team can review your plans and help you choose the right wood and board size.
