The Construction Master Pro 4065 is the professional-grade construction calculator trusted by contractors, framers, architects, and estimators across North America — and available at The Contractors Site for Ontario construction professionals who need the most capable job site calculator available. From complex roof geometry to stair layout to concrete estimation, the Construction Master Pro handles the calculation challenges that separate professional construction from guesswork.

Feet-Inch-Fraction Input as Native Language

The Construction Master Pro takes tape measure readings as direct input — feet, inches, and fractions entered exactly as they are read, without conversion. The calculator's native language is the same as the tape measure, which means the translation step between the field measurement and the calculation is eliminated. Fewer steps, fewer errors, faster workflow.

The Construction Master Pro is an award-winning advanced feet-inch-fraction construction-math calculator with powerful built-in solutions perfect for completing layouts, plans, bids and estimates. Calculate circles, roofs, stairs, and more. Works in and converts between feet-inches-fractions and decimals, including metric. Use it in the field or office to save time, reduce costs, prevent re-work and maximize profits.

Construction Calculations:

  • Work in and convert between building dimensions, including Metric
  • Built-in Right-Angle solutions
  • Areas, Volumes, Square-ups
  • Complete Stair Layouts
  • Roof, Rafter and Framing solutions
  • Circle: Arcs, Circumference, Segments
  • Drywall - Siding and Panels
  • Stairs - Riser Height and solve for Stairwell Opening
  • Studs On-center
  • Compound Miter Cuts
  • Arched Rake-Walls
