Calculators
Working calculators for quick planning.
Enter the measurements you have, keep units consistent, and use the formula notes to understand how each result is estimated.
Carpentry
Stair Calculator
Lay out stair risers and treads from total rise and preferred riser height.
Results
Enter the required measurements to calculate results.
Risers = rounded total rise / target riser. Actual riser = total rise / risers. Treads = risers - 1. Total run = treads x tread depth.
Help
- Check local stair code for max riser, min tread, nosing, width, headroom, and landings.
Carpentry
Rafter / Roof Pitch Calculator
Estimate pitch factor and common rafter length from run and rise per foot.
Results
Enter the required measurements to calculate results.
Pitch factor = sqrt(12^2 + rise^2) / 12. Rafter length = (run + overhang) x pitch factor.
Help
- Common rafter estimate excludes ridge thickness, birdsmouth layout, fascia details, and field cuts.
Carpentry
Stud Count Calculator
Estimate wall studs by wall length and on-center spacing.
Results
Enter the required measurements to calculate results.
Base studs = floor(wall length in inches / spacing) + 1, then add entered corner and opening allowances.
Help
- Does not automatically frame headers, jacks, kings, intersections, or backing; enter those as allowances.
Carpentry
Joist Spacing Reference
Estimate joist count for a deck or floor layout width.
Results
Enter the required measurements to calculate results.
Joists = floor(width in inches / spacing) + 1, plus entered rim/band pieces.
Help
- Span sizing is structural and must be checked separately for species, grade, load, and code.
Carpentry
Decking Quantity Calculator
Estimate deck boards from deck size, board width, gap, and waste allowance.
Results
Enter the required measurements to calculate results.
Board count = deck width in inches / (board width + gap), then apply waste allowance.
Help
- Assumes boards run the deck length and ignores picture framing, breaker boards, stairs, and pattern changes.
Carpentry
Board Foot Calculator
Calculate board feet from thickness, width, length, and quantity.
Results
Enter the required measurements to calculate results.
Board feet = thickness in inches x width in inches x length in feet x quantity / 12.
Help
- Uses nominal or actual dimensions as entered; choose one method and stay consistent.
Carpentry
Trim / Baseboard Estimator
Estimate linear trim from room perimeter, openings, and waste allowance.
Results
Enter the required measurements to calculate results.
Net trim = perimeter - opening deductions. Buy length = net trim x (1 + waste). Pieces = buy length / stock length.
Help
- Does not optimize exact cut lists or pattern matching.

Before You Calculate
Start with clear measurements.
Measure the finished opening, run, rise, span, or surface area.
Record material dimensions and spacing assumptions.
Allow room to note waste, cuts, and site-specific conditions.
