WHAT YOU CAN DO

• FRAME A SINGLE WALL Enter wall length, height, and on-center spacing (12", 16", 19.2", or 24"). Choose 2x4 or 2x6 lumber. Get instant stud counts, top and bottom plate lengths, board feet, wood volume, and wall area, with a live visual layout and your choice of end-stud configuration (single, double, California corner, or gap corner).

• RAKE AND GABLE WALLS Switch to rake mode and enter a pitch (3:12, 4:12, 6:12, 8:12, 9:12, 12:12, or custom) or the low and high heights. The app outputs the exact length of every stud, ready to cut.

• DOORS, WINDOWS, AND CORNERS Drop in any opening with its rough opening dimensions. King studs, jack studs, cripples, sills, and headers are calculated for you. The layout adjusts in real time around every opening.

• 4×8 SHEET LAYOUT Toggle the sheathing overlay to see exactly where OSB or plywood panels land on your wall. Edges that fall on a stud are highlighted green; unsupported joins are flagged red so you can adjust before you start nailing.

• PRE-CUT STUD PRESETS One tap loads standard pre-cut heights: 92-5/8" (8' wall), 104-5/8" (9' wall), or 116-5/8" (10' wall). The wall height is set for you including plate thickness.

• MARK-OUT GUIDE Get a copy-ready list of measured positions along the plate. Copy to clipboard, print, or include in the PDF — perfect for marking studs on-site without re-counting.

• MULTI-WALL PROJECTS Save entire framing jobs across multiple walls with intersection tracking (T-junctions automatically deduct shared studs from the total). Track totals: studs, plates, board feet, wood volume, wall area, and estimated cost. Export a professional PDF with diagrams, cut lists, mark-out positions, and material summary.

• IMPERIAL AND METRIC Work in feet-inches-fractions down to 1/8", or in millimeters. Switch units at any time without losing your project.

• IRC REFERENCE BUILT IN Quick-access cheat sheets: IRC R602.7 header sizing for load-bearing openings, nominal vs. actual lumber dimensions, common rough opening sizes for doors and windows, corner stud configurations, and roof pitch to angle conversions.
