Method
How to use this calculator
- 01
Enter room length, width, and number of matching rooms.
- 02
Subtract the combined width of openings without baseboard.
- 03
Add measured transition lengths at doors or floor changes.
- 04
Apply waste and compare baseboard and transition totals separately.
Good for
Useful planning situations
- Baseboard takeoffs
- Shoe molding estimates
- Doorway transition planning
Working model
Assumptions
- Each room is rectangular and uses the same measurements.
- Opening deductions are entered as a combined linear length per room.
- Waste is applied separately to baseboard and transitions.
Before ordering
Limits and checks
- Inside/outside corner cut strategy and stock lengths affect actual purchases.
- Built-ins, curved walls, stairs, and irregular rooms require separate segments.
- Transition profile selection and substrate movement requirements are not evaluated.
Field notes
Frequently asked questions
Do I subtract every doorway?
Subtract only widths where baseboard or molding will not run. Measure each opening rather than relying on a standard door size.
Why are transitions reported separately?
Transitions are typically different products and stock lengths, so combining them with baseboard would make ordering less useful.
How do stock lengths affect the order?
Linear totals do not guarantee efficient cuts. Lay out required segments against available stick lengths and allow for miters and defects.
