How to use this calculator
- Enter Room perimeter in ft.
- Enter Door openings.
- Enter Stick length in ft.
- Press Calculate. The highlighted row is your order quantity; the note beneath it translates the number into real-world terms.
Formula & constants
Baseboard need = room perimeter minus door openings, +10% for miter waste. Sticks come 8, 12 and 16 ft; longer sticks mean fewer joints on long walls. Every default in the fields above is editable — when your supplier’s spec sheet lists a different density, coverage rate or price, enter that number instead. The waste and compaction allowances follow common trade practice; see our methodology page for the derivation of each formula and the standards it references.
Where this fits in the project
Interior finishing runs framing-out: studs, insulation, drywall, then paint and floor coverings. Measure once and reuse the same wall and floor areas across each material takeoff.
How this connects to your project
No quantity stands alone — each material in the chain depends on the ones around it. These are the planning steps that pair with the baseboard calculator:
- Drywall Calculator — Baseboard covers the drywall-floor junction.
- Flooring Calculator — Baseboard finishes the floor-to-wall transition.
- Paint Calculator — Baseboard is typically painted separately from walls.
- Crown Molding Calculator — Baseboard at floor, crown at ceiling — room trim package.
- Laminate Flooring Calculator — Baseboard hides the laminate expansion gap.
- Carpet Calculator — Baseboard covers the carpet-to-wall edge.
- Tile Calculator — Baseboard finishes tile floor edges.
Frequently asked questions
How much extra for miters?
10% covers outside-corner miters and defects; complex rooms with many corners need 15%.
Cope or miter inside corners?
Cope — coped joints stay tight when wood moves seasonally; mitered inside corners open up.
Last verified: — prices reflect current national averages. See our methodology.
Estimates are for planning. Material densities, coverage rates and prices vary by region and supplier — confirm final quantities before ordering, and check local code where structural or electrical work is involved.
