Enter Deck area (m2) and the Deck Board Calculator calculates Boards 140 mm plus 5 mm gap, Joists at 400 mm in one step. It is built for home & construction jobs where a quick, repeatable answer beats guesswork. Board count assumes straight runs; diagonal patterns waste 15% or more.
The calculator multiplies your input by a fixed coefficient for each line. For example, every 1 m2 gives 6.8966 linear m for boards 140 mm plus 5 mm gap.
If you enter 22.5 (Deck area (m2)), Boards 140 mm plus 5 mm gap comes to 155.17 linear m and Joists at 400 mm comes to 56.25 linear m.
Each 1 m2 gives 6.8966 linear m.
Joists at 400 mm equals your input times 2.5 linear m. With 22.5 entered, that is 56.25 linear m.
Multiplication is exact; the inputs behind boards 140 mm plus 5 mm gap are typical figures, so check them against your own conditions. This is general information, not professional advice.
Board count assumes straight runs; diagonal patterns waste 15% or more.
