Estimate board rows with gap and standard board length wey you choose.

Your numbers

Rows of boards

—

Planning estimate from your measurements and assumptions. Confirm dimensions, product coverage and local installation requirements before you buy.

Formula

Use N = ceil[(W+g)/(b+g)]. W na deck width, b na board width, and g na gap, all for di same unit. ceil dey round up to board rows. Stock board count still account for length without reusing cut pieces.

Estimate board rows with gap and standard board length wey you choose.

Example wey show the calculation

Deck length along board direction (m): 5
Width of the deck (m): 3
Width of one board (mm): 140
Gap between the boards (mm): 10
Length of standard board wey you buy (m): 5

Rows of boards: 21
Standard boards if you no reuse cut pieces: 21
Total length of boards wey you go install: 105 m
