Stud Framing Layout Calculator

Plan wall framing with precision — right from your phone.

Stud Framing Layout Calculator is the go-to tool for carpenters, builders, and DIY enthusiasts who need accurate stud positioning, material counts, and cost estimates on the job site or at the planning desk.

Enter your wall dimensions and openings (doors, windows, pass-throughs), and the app instantly calculates every stud position, adjusting for headers, cripple studs, king studs, and jack studs. The interactive color-coded diagram shows exactly where each piece goes, so you can visualize the entire wall before cutting a single board.

KEY FEATURES

• Exact & Spread Spacing Modes — choose fixed on-center spacing (12", 16", 19.2", 24") or let the app spread studs evenly across panels for optimal material use.

• Imperial & Metric Units — switch seamlessly between inches/feet and millimeters. Fractional inch display, decimal inch, and feet-inch modes are all supported.

• Multiple Openings — add unlimited door and window openings with individual left position, width, height, head height, and header depth. The app validates each one and warns if dimensions collide or fall out of range.

• Interactive Diagram — pinch to zoom into a full color-coded wall diagram showing plates, studs, headers, sills, and cripples. Dimension labels update in real time.

• Sheet Layout Planner — toggle sheathing visualization to see where plywood or OSB sheets land on your wall. Join lines, sheet numbers, and cut lengths are displayed so you can plan your sheathing before you start.

• Cost Estimator — enter your local prices for studs, plate lumber, and header material. The app multiplies quantities by price and gives you a total material cost breakdown instantly.

• Quick Presets — one tap loads common wall configurations: Standard 8' Interior, 9' Interior, Exterior 2x6, Garage Door Wall, or Basement 2x4. Customize from there.

• Internal Intersections — mark where interior walls tie in and the calculator adjusts stud positions around the intersection automatically.

• Noggings / Blocking — toggle horizontal blocking visualization to plan fire stops or mid-height bracing.

• PDF Export & Share — generate a professional PDF report containing all input settings, the wall diagram, stud run positions, opening ranges, sheet layout, and cost breakdown. Share it with your crew, email it to a client, or save it for your records.

• Single & Double End Studs — configure single, double, or gap end stud configurations to match your local building code requirements.

Whether you are framing a single partition wall or planning an entire house, this calculator saves hours of manual layout math and helps you order the right amount of lumber — no more, no less.
