Board Count Estimate
You need 338 linear feet. This is equivalent to approx 29 x 12ft boards or 22 x 16ft boards.
Fastener Estimate
Plan for about 350 screws per 100 sq ft of decking (assuming 16" joist spacing). For your 144.0 sq ft deck, you'll need roughly 504 screws.
Board Width Impact
Using wider boards (e.g., 7.25") would reduce the linear footage needed but might cost more per foot. Narrower boards require more fasteners and installation time.
How to Use
Step-by-step instructions
- 1Enter the length and width of the deck (in feet).
- 2Enter the board width (in inches).
- 3Enter the gap spacing (in inches).
- 4Enter wastage percentage.
- 5The calculator will provide the total linear feet of decking needed.
Decking Material
Calculates the total linear feet of decking material required based on the deck area and the width of the boards including the gap.
Linear Feet = Area / (Board Width + Gap)Variables:
AreaTotal area of the deckBoard WidthWidth of a single deck boardGapSpacing between boardsExample
12x12 Deck
Inputs:
Size:12 ft x 12 ft
Board:5.5 inches (standard 5/4x6)
Gap:1/8 inch
Steps:
- 1.Area = 144 sq ft
- 2.Unit Width = (5.5 + 0.125) / 12 = 0.46875 ft
- 3.Linear Feet = 144 / 0.46875 = 307.2 ft
- 4.+10% Wastage = 338 ft
Result:
338 Linear Feet
