How to use decking calculator estimates

Treat the estimate as a starting point

Calculator output helps shape the first list, but final quantities depend on layout, joins, waste allowance and accessory choices.

Enter finished dimensions first.
Adjust for board direction and joins.
Add fixings, framing and finishing pieces separately.
