The **Deck Boards Count** calculator computes the number of decking boards required for a floor or deck based on the dimension of the room or deck and the specifications of the boards.

**INSTRUCTIONS:** Choose your units (e.g. feet, inches, meters) and enter the following:

**Floor Width**- the width of the floor or deck**Floor Length**- the length of the floor or deck**Board Size**- the size of the decking boards. This is a pull-down menu where you can select from the following standard decking board sizes: 6" x 12', 6" x 16", 150 mm x 4800mm, 146 mm x 4800 mm, 225mm x 3600mm.

The Deck Boards Count calculator computes the number of decking boards needed to achieve the specified surface area.* Decking Boards * * Floor Joists and Plates (end pieces). *

The most common decking board sizes in North America are:

The North American boards are actually 5.5 inches wide. The assumption is a half inch gap between the boards. In Europe, the most common sizes are measured in millimeters as follows:

Deck boards are either laid perpendicular to the floor or deck joists, or on a diagonal pattern. The goal is to transfer the weight on the deck boards to the floor joist in a short distance. Never run the deck boards parallel to the floor joists.
