About this app

BoardCalc helps builders, carpenters, remodelers, and DIYers solve everyday jobsite math without juggling paper notes, span charts, or a generic calculator. Enter measurements the way you use them in the field, including feet, inches, and fractions, then get clear results for stairs, roofs, board feet, rafters, materials, arcs, and unit conversions.

Then the feature list should be framed around outcomes:

Plan stairs with riser, tread, run, stringer, and angle results.
Estimate roof pitch, roof area, diagonal lengths, hip/valley rafters, and jack rafters.
Calculate board feet, area, and material weight from jobsite dimensions.
Convert between metric and imperial units without leaving the calculator.
Copy results so you can save, share, or double-check them later.

What’s new

Clearer construction results.

• Roof: pitch, angle, and rafter length — no shingle/underlayment estimates without full roof measurements
• Diagonal & pitch: geometry only; notes explain pitch ratio vs actual half-span
• Stairs: results use your Stair Code Settings; notes explain how run and tread depth are calculated
• Jack rafters: 16" OC and per-hip/valley quantity labeled clearly
• Weight & arc: clearer density and geometry notes
• Early-install tracking for future updates
