This static version focuses on rectangular-room planning. Window trim mode, mitre-cut reuse rules, and offcut optimisation remain later-phase enhancements.

The main answer rounds the linear run with waste up to whole sold stock lengths. Optional nail spacing adds a simple fastener estimate only when you enter it.

Trim calculator FAQ

Does this optimise offcuts?
No. This static batch keeps the workflow simple by using linear run plus waste and then rounding to whole stock lengths.

Can I deduct doors?
Yes. Enter a door count and average door width to reduce the total run before waste is applied.
