About
Storypole is the tape-measure calculator for the trades — offline, no account, no subscription. Buy it once.
THE TAPE IS THE INTERFACE
Every answer lands on a real blade you can drag. Scrub to a measurement with your thumb and the scale follows you: coarse for a whole run, fine for a sixteenth. Tap the blade to place a mark. No other feet-inch calculator lets you feel the number.
FEET, INCHES, FRACTIONS — EXACTLY
Punch what you measure: 8' 4-1/2". Add, subtract, multiply and divide in exact fractions — no floating-point drift — and read the result to your chosen precision, 1/2 down to 1/64. Type a 1/32 on a 1/16 display and the precision RAISES instead of quietly rounding your keystrokes away.
LAYOUT, ACTUALLY MARKED OUT
• Equal spacing — the full list of marks to pull, not just a count
• On center — 16", 19.2" and 24", with the odd last bay stated instead of hidden
TAKEOFF AND GEOMETRY
• Area, volume, cubic yards
• Roof pitch and rafter length
• Square up (3-4-5), miter and bevel, circle and pipe wrap
LUMBER AND WIRE
• Board feet
• Dressed size — the real 1-1/2" x 3-1/2" behind a "2x4" (NIST PS 20-20)
• Wire gauge — AWG diameter in inches and millimetres (NBS Handbook 100)
EVERY NUMBER HAS A SOURCE
Each calculator names the standard behind it: NIST SP 811 rounding, NIST PS 20-20 lumber, the 1959 international inch, USDA Agriculture Handbook 73, NBS Handbook 100. The Reference tab carries the citations, so you can check a number instead of trusting it.
ON YOUR WRIST
The watch app runs the same arithmetic — tape calculator, converter, roof pitch, board feet and more — with the Digital Crown for fine entry.
BUILT FOR THE SITE
High-contrast design, glove-sized keys, full landscape, and it works with no signal at all. iPhone, iPad, Mac and Apple Watch — one purchase, no subscription, no ads.
