About this app

Western Construction Calculator is a construction calculator built the way tradespeople actually measure — in feet, inches, and fractions, not decimals.
FEET-INCH-FRACTION MATH
Enter measurements exactly like you'd read them off a tape measure. Add, subtract, multiply, and divide dimensions directly, with results shown in feet-inches-fractions, not confusing decimals.
BUILT-IN TAKEOFFS
• Blocks and brick count from a wall length
• Drywall sheet count from a room's square footage
• Concrete footing and stem wall takeoffs
• Board feet, weight, and cost calculations
ADVANCED CONSTRUCTION TOOLS
• Stairs: riser height, tread depth, stringer length, and stairwell opening from your code-max riser and target tread
• Roofing: rise/run/diagonal/pitch, hip & valley (including irregular pitches), jack rafters, rake-wall studs, and roof material takeoffs
• Arc: arched openings and circle segments, plus arched wall stud layouts (inside or outside framing)
• Compound Miter: miter and bevel angles for crown molding at any spring angle
• Polygon: layout math for equal-sided decks, gazebos, and framing
• Plumbing: pipe offset and rolling offset calculations
• Blueprint scale conversions and general unit conversions
• Board feet and volume calculators
VOICE INPUT
Enter measurements and run calculations hands-free — say a dimension or a full calculation and it enters exactly as if you'd typed it, useful with your hands full or gloved on the job site.
MEMORY & HISTORY
Three numbered memory registers plus a running total, a full calculation history you can search and export per project, and separate project tracking for keeping different jobs organized.
BUILT-IN USER MANUAL
Every key, every Advanced screen, and every setting is documented in-app — long-press any button to jump straight to its own explanation.
Whether you're framing a roof, laying out stairs, or just adding up a materials list, Western Construction Calculator keeps your math in the units you actually use on the job.
FREE TO TRY
