Estimated cost — your price

This site holds no price list for this material — local prices vary too much to publish honestly. Enter your supplier's price and the result is costed with it.

Preliminary estimate, not certified engineering. This tool produces an indicative quantity calculation for planning purposes only — it is not a certified structural analysis, a guaranteed material takeoff, or a substitute for building department approval. Always verify measurements on-site and have a licensed contractor or structural engineer review any load-bearing, code-sensitive, or safety-critical work before purchasing materials or starting construction. Spotted an arithmetic or standards error? Report it to contact@craftquantities.com with your inputs — confirmed fixes become pinned regression tests.

Regulatory standards & verification citations

  • Room perimeter = 2 x (length + width) for a rectangular room; trim is commonly stocked in 8, 10, 12, 14, and 16 ft sticks
  • 10-15% waste is standard to account for cuts, corners (mitered at 45°), and mistakes

Frequently asked questions

Why subtract doorways but not windows?
Baseboard runs along the floor, so only floor-level openings like doorways interrupt it — windows are up on the wall and don't affect baseboard length.
Should I buy exactly this many sticks?
Round up, which this calculator already does — leftover trim is useful for patch repairs later, and running short mid-project means an extra supply trip.
Does corner mitering waste extra material?
The 10% waste factor already accounts for standard 45° corner miters. Rooms with unusual angles may need a higher factor.
