Frequently Asked Questions
Common questions about Deck Board Estimator, formulas, and expected usage.
What does this deck estimator calculate?
It estimates board rows, total linear footage, and total board count from deck size, board width, board gap, and stock length.
Why include board gap in the calculation?
Deck gaps affect how many rows fit across deck width, so they change total board count.
Does this include waste and defects?
No. Add extra material for cuts, sorting, defects, and board-selection preferences.
Can this estimate fasteners too?
Not directly. You can use row count and joist layout to estimate screw quantities separately.
