Conduit Bending Calculator

The conduit bending calculator for electricians: every bend type, plus conduit fill, voltage drop and NEC reference tables. One-time Pro unlock — no subscription.

BendSnap is the pocket conduit bending calculator built for electricians. Get accurate mark points for every bend type in seconds—no trigonometry, no math errors, no scraps of paper.

ALL YOUR BENDS IN ONE PLACE

• Offset bends — 30°, 45°, 60°, 22.5° and any custom angle

• Stub-Up (90°) — auto take-up by conduit size

• Saddle bends — 3-point and 4-point obstacle crossings

• Back-to-Back — precise parallel-run spacing

• Segment / large-radius bends

• Rolling Offset and Kick bends

• Multi-Bend Layout — lay out an entire run with every mark and bend order on one conduit

MORE THAN BENDS

• Conduit Fill — NEC Chapter 9 fill for conductors in EMT, IMC, RMC and PVC

• Voltage Drop — volts and percent lost, with the NEC 3% branch-circuit guide

• Parallel Conduit — size a parallel run in one pass

• Spirit Level — digital level built on the device accelerometer

PROFESSIONAL RESULTS, INSTANTLY

• Live reactive diagrams redraw as you type

• Length, shrinkage and take-up computed for every bend

• Fractional-inch keypad — type 3/4" directly, no sliders to fight

• Inches ↔ millimeters, switch any time

• Save custom benders and reuse them across calculators

ON THE JOB SITE

• Calculation history with timestamps

• Share results through any app, or export to PDF

• Quick-reference tables: bending multipliers, take-up and shrink formulas — your pocket cheat sheet

DESIGNED FOR THE FIELD

Clean, high-contrast Safety-Orange interface that's readable in bright sun or a dim crawlspace. Light and dark themes. English, Spanish, Russian, Thai and Chinese in one app. All bending calculations, diagrams, reference tables and history run entirely on your device—no account, no signal needed.

Unlock Pro once — a one-time purchase ($1.99), never a subscription — for unlimited custom benders and presets. No sign-in. (The price is always shown in the app before you buy.)

BendSnap: precise bends, faster work.
