FramerCalc: Carpentry Tools

FramerCalc is a focused carpentry calculator for carpenters, framers, remodelers, builders, and serious DIY woodworkers.

Turn measurements into clear results for stair stringers, common rafters, board feet, stud and joist layouts, sheet goods, concrete volume, square-up diagonals, feet-inch fractions, and material takeoffs.

Built for the way work happens on site:
- Stair stringers: risers, treads, total run, stringer length, and IRC reference warnings
- Rafter / roof pitch: common rafter length, rise, pitch angle, plumb cut, seat cut, overhang, roof area, and sheathing estimates
- Board feet: nominal lumber volume, quantities, and cost
- Stud / joist layout: on-center count, mark positions, openings, extras, and plate estimates
- Sheet goods: drywall, OSB, plywood, waste, orientation, and order area
- Concrete: cubic feet, cubic yards, and bag count
- Square-up diagonal: quick 3-4-5 layout checks
- Unit converter: feet-inch-fraction, decimal inch, decimal foot, and metric
- Fraction calculator and feet-inch tape math
- Job takeoff: material quantities, waste, units, and cost
- Crown miter: flat crown molding miter and bevel settings

Core calculators work offline, with no account, no ads, no tracking, and no usage analytics. Network access is only requested when you use purchase, restore, or links you choose to open.

The optional Pro unlock is a one-time purchase, not a subscription. It adds workflow upgrades such as more saved job records, diagram PDF exports, and custom IRC reference limits.

FramerCalc is designed to be fast enough for the jobsite and clear enough to double-check before you cut.
