How to Use the Wall Framing Calculator

Plan your wall framing project in minutes. This free tool generates an IRC-compliant cut list for studs, plates, headers, and all framing members—no carpentry experience required.

  1. 1

    Enter Wall Dimensions

    Type your wall's length and height in feet and inches. Use decimal inches or whole inches—the calculator handles both. Select your wall type: interior partition walls use 2×4 studs; load-bearing exterior walls use 2×6 studs per IRC requirements.

  2. 2

    Choose Stud Spacing

    Select 16" on center (O.C.) or 24" O.C. spacing. Most residential framing uses 16" O.C. for exterior walls and load-bearing walls. 24" O.C. is common for non-load-bearing interior partitions and can reduce lumber costs by up to 25%.

  3. 3

    Add Openings (Windows, Doors, Garage Doors)

    Click + Add Window, + Add Door, or + Add Garage Door for each opening in your wall. Enter the rough opening width and height. The calculator automatically adds king studs, jack studs, correctly sized headers, and cripple studs per IRC code.

  4. 4

    Review Your Materials Cut List

    The Materials Cut List below the visualization shows every piece of lumber by type, quantity, and length. The Cost Estimator calculates total lumber cost based on current board-foot pricing. Add a 10–15% overage for waste and cuts.

  5. 5
