Understanding Deck Material Calculations

Accurate deck planning requires understanding a few basic measurements.

Deck Area

Deck area is calculated by multiplying:

• Length × Width

This determines the total surface space of the deck.

Board Coverage

Each board covers a specific amount of surface area depending on:

• Board width
• Board length

The calculator divides the deck area by the board coverage area to estimate the number of boards required.

Waste Allowance

A waste allowance is added to account for:

• Cutting errors
• Damaged boards
• Installation adjustments

Most deck projects include around 10% extra materials.
