About this app
Decimals guess. Fractions don't.
TapelineCalc is a construction calculator for feet, inches and fractions — built for the trades: framing, finish carpentry, concrete, stairs, roofs. Type measurements the way you read a tape measure and get exact answers, not decimals pretending to be fractions.
A FEET INCH CALCULATOR WITH EXACT MATH
• Add, subtract, multiply and divide feet-inch-fraction dimensions
• Results stay exact: 25' 7-1/4" means 25' 7-1/4", not 25.604166…
• Decimal inches and metric shown alongside every result
• Fraction precision you choose, from 1/2 down to 1/64
• A true fraction calculator core — no floating point anywhere a measurement lives
THE TAPE
• Every entry and every step stays on the tape above the keypad — like the desk tape calculators the trades already trust
• A running total after each step — check your math at a glance
• One-tap back to fix the last entry without clearing the job
THE HONESTY FLAG
• If a display value has to round to your chosen precision, the app tells you: "≈ TO NEAREST 1/16"
• The math underneath stays exact — only the display rounds, and never silently
SEVEN JOBSITE ESTIMATORS
• Stair calculator — risers, treads, total run, stringer length
• Concrete calculator — slabs, footings, post holes: volume, bags or yards, waste
• Roof pitch calculator — rise, run, rafter length
• Area calculator — multiple regions, minus openings; ft², yd², m², acres
• Gravel & mulch — bed volume by material
• Diagonal — square your layout with the 3-4-5 check
• Length convert — feet-inch, decimal inches and metric, both directions
• Your inputs are saved per tool — tomorrow's job picks up where you left off
MADE FOR THE TRADES — AND EVERYONE WHO MEASURES
Carpenters, contractors, framers, concrete crews, roofers, remodelers, woodworkers and DIY builders: if your day runs on a tape measure and imperial measurements, this calculator speaks your language. Use it for estimating materials, checking a takeoff, or converting a plan's metric dimensions right on the jobsite.
CITED, NOT GUESSED
Every constant the estimators use — densities, yields, code limits — is cited inside the app. Check the math yourself.
WORKS ANYWHERE
• 100% offline. No account, no sign-up, no cloud.
• Every tool is free, forever.
• One optional purchase removes ads. Nothing else is paid, ever.
Whether you call it a construction calculator, a feet and inches calculator or a tape measure calculator — this is the one that never rounds behind your back.
