Trim and Molding Linear Foot Calculator

Enter the room size and the doors and windows and see linear feet of baseboard, casing and crown to order.

These tools give planning-level estimates from typical values. They are not quotes, designs or engineering, and results depend on your actual materials, framing, access, local rules and conditions. Only a site visit can confirm what a project needs, and we give you a written scope and price before any work begins.

How it works

Four quick steps.

  1. 01

    Enter the room size

    Length and width in feet.

  2. 02

    Subtract openings

    Doors and windows change baseboard length.

  3. 03

    Pick the trim

    Baseboard, casing and crown.

  4. 04

    Read the lengths

    Linear feet to order with waste.

Tips

  • Trim comes in common lengths, so plan joints on walls longer than the stock.
  • Order ten percent extra for miters and mistakes.
  • Crown molding runs the full perimeter of the room.
