Baseboard Calculator

Calculate linear meters, number of baseboard pieces and cost with doorway deductions.

When this estimate is most useful

  • For standard rooms. Use length and width and let the calculator build the perimeter.
  • For complex layouts. If you already measured perimeter manually, switch to custom mode.
  • For purchasing. The result gives you total length, piece count and a quick cost estimate.

FAQs

Should I deduct door openings?

Yes. In most rooms, baseboard does not run through the door opening, so that width should be deducted from the perimeter.

How much waste should I allow?

Five to seven percent is often enough for a simple room. If there are more cuts, tricky corners or material defects, use a slightly higher reserve.
