EMT Conduit Bending Calculator

Conduit bending calculator for electricians and apprentices. Enter your measurements the way your tape reads them and get every bend mark, measured from the end of the conduit, with the shrink, the distance between bends and the steps in the order you bend them. Works completely offline.

WHAT IT CALCULATES
• Offsets: distance between bends, shrink, and the first mark from the end of the pipe when there is an obstruction
• Rolling offsets: true offset and roll from the rise and the roll
• Parallel offsets and parallel kicks: how far to shift each conduit so a rack stays evenly spaced
• 3-point saddles with a 45°, 60° or 90° center bend, and 4-point saddles over boxes, beams and ducts
• 90° stub-ups using the take-up of the bender in your hand, back-to-back 90s and conduit needed
• Kicks: travel, run and shrink, or the angle from rise and run
• Segmented 90s and concentric bends: degrees per shot, mark spacing, developed length
• Compound 90s around a round, square or rectangular obstruction in a corner
• Field matcher: measure a bend that already exists and get the angle to match it
• NEC conduit fill (Chapter 9) for EMT, IMC, rigid, PVC 40 and 80, FMC and ENT, and box fill per NEC 314.16

REAL BENDER TAKE-UP
Pick your bender and shoe size and the marks use its real take-up and radius. The catalog covers Klein, Greenlee, IDEAL, Milwaukee, Southwire and Gardner Bender hand benders from 1/2" to 1-1/4" EMT and rigid, plus Greenlee 1818 and 555 shoes. Edit any value or add your own bender.

MARKS YOU CAN TRUST
Exact trigonometry corrected for the centerline radius of the shoe, so marks land within 1/16" at any angle. Prefer the numbers on the bender sticker (30° = 2, 45° = 1.4, shrink 1/4" and 3/8" per inch)? Switch to field rules and both values are shown side by side.

FAST TO ENTER ON A JOB SITE
Tap a value and type it on a tape-style keypad with 1/8, 1/16 and 1/32 chips. Feet and inches, millimeters or centimeters. Angles that cannot be bent with your numbers are flagged before you tap them.

SEE THE BEND BEFORE YOU BEND
A numbered drawing of the conduit with true bend arcs, a 3D view you can turn, a tape strip with every mark from the same end, and guide mode that walks you through one bend per screen.

SAVE, SHARE AND PLAN
Save any bend as a job with a name and a note. Recent calculations are kept automatically. Share a PDF bend sheet, a CSV or plain text. The run planner fits several bends on one stick and warns about overlaps.

ALSO INCLUDED
Level and angle finder that buzzes at your target angle. Quick reference charts for multipliers, shrink, saddle constants, take-up, gain and conduit sizes. A built-in manual that shows what to measure for each bend.

FIVE LANGUAGES
English, Spanish, French, Portuguese and German, including the PDF bend sheets.

PRIVATE AND OFFLINE
No account, no ads, no analytics, no internet needed. Your jobs and benders stay on your phone.

Always check marks against the deduct stamped on your bender before bending. This is a layout aid for trained electricians. Klein, Greenlee, IDEAL, Milwaukee, Southwire and Gardner Bender are trademarks of their owners; this app is not affiliated with them.
