Carpentry & Framing Calculator

Turn measurements into accurate mark-outs before you cut, drill, frame, or install. Carpentry & Framing Calculator brings eight focused layout tools into one practical jobsite app. Enter your dimensions, choose metric or imperial units, and get clear results, visual diagrams, running measurements, and shareable PDF reports. CALCULATORS INCLUDED • Wall Framing — stud counts, centers, sheeting layout, rake angles, timber length, wall area, and running marks. • Wall Framing Openings — lay out doors and windows with studs, plates, tolerances, opening areas, and detailed mark-outs. • Gable Studs — calculate stud lengths, pitch or angle, rake length, top-cut setback, and stud schedules. • Board & Batten Spacing — create balanced equal or exact spacing with flexible end and measuring options. • Angled Spacing — space members along slopes and through gables, with member schedules and running lists. • Running Set-out — generate repeated marks from one origin and step through every position on site. • Fastener Spacing — distribute screws, nails, or anchors evenly, including edge and end offsets and a mark-out template. • Shelf Spacing — calculate equal, adjusted, custom, or Hambridge shelf gaps plus top, center, and bottom measurements. BUILT FOR REAL WORK • Metric and imperial dimensions • Decimal and fractional-inch entry • Clear diagrams that make layouts easier to understand • Running measurements ready to transfer directly to the workpiece • PDF export for sharing, printing, or keeping with project notes • Fast recalculation when dimensions or options change Ideal for carpenters, framers, builders, contractors, cabinetmakers, installers, woodworkers, and serious DIY projects. Spend less time rechecking formulas and more time building. Whether you are framing a wall, setting out studs around openings, balancing battens, spacing shelves, or marking fasteners, the app keeps the measurements organized and ready when you need them.
