Multiplier For A 45 Degree Bend
Multiplier for a 45 degree bend is simple with WireGaugeCalc, since you enter the rise and read the travel at once.
It uses the standard 1.4 multiplier and your offset height to give the distance between bend marks.
So your conduit lands at the right height the first time.
Open the calculatorEnter any two values and read the rest.
Ohm’s law: V = I × R and P = V × I. Field aid only, verify against the current NEC and your local authority having jurisdiction.
Find Your Offset Travel Length
You enter the rise you need, and the calculator multiplies it by 1.4 to give the travel between the two 45 degree marks.
Since the multiplier comes from the geometry of the angle, the result holds for any rise you type.
The screen shows the mark spacing, so you can measure and bend without guessing.
Why 1.4 Works For A 45 Degree Offset
The multiplier comes from a fixed relationship you can rely on:
- Uses 1.4 as the travel multiplier for two 45 degree bends
- Takes the rise or offset height you enter
- Returns the distance between bend marks
- Works for EMT, IMC, and rigid conduit
- Adds shrink so the conduit ends where you want
One app for every NEC calculation
WireGaugeCalc keeps the calculations you reach for most in one place:
- Voltage drop and wire sizing for any run
- Conduit fill for EMT, PVC, and RMC
- Box fill and junction box sizing
- Ampacity and temperature derating
- Motor circuit and load calculations
- Conduit bend offsets and saddles
Built for the field, works offline
The whole app runs on your phone, so it keeps working in a basement, an attic, or a job site with no signal.
There is no account to create and nothing to load. Open it, run the number, and get back to work.
- No signup and no signal needed
- Answers in a tap, not a spreadsheet
- Same tool on phone, tablet, and desktop
Every result cites the NEC article
Each answer shows the table or formula it came from, so you can check the method and learn the code as you go.
That makes the app useful on the job and during exam prep, since the reasoning is right next to the number.
Switch the code year your job runs on
Jurisdictions adopt the NEC at different times, so you can match the calculation to the code in force:
- NEC 2017, 2020, and 2023 tables
- Copper and aluminum conductors
- 60, 75, and 90 degree C terminations
- Single-phase and three-phase systems
Run the number, then get back to work

Where does the 1.4 multiplier come from?
It is the ratio of travel to rise for a 45 degree offset, which equals 1 divided by the sine of 45 degrees. That works out to about 1.414, and most benders round it to 1.4.
How much shrink should I expect on a 45 degree offset?
Plan for roughly 3/8 inch of shrink per inch of rise on a 45 degree offset, then add it so the run reaches its target. Confirm bending practices against the current NEC and your local authority having jurisdiction when fill and support matter.
Is WireGaugeCalc free to use?
Yes. Every calculator is free to run with no signup. A paid tier adds saved projects, PDF reports, and extra code years, but the core math stays free.
Does it work without internet?
Yes. The app runs on your device, so it keeps working with no signal on a job site, in a basement, or in an attic.
Are the results code accurate?
Results follow published NEC tables and standard formulas, and each answer shows the article it came from. It is a field aid, not a stamp of approval, so verify against the current code and your local authority before you wire anything.
Which NEC code year does it use?
You can switch between NEC 2017, 2020, and 2023, since jurisdictions adopt the code at different times. Pick the year your job runs on.
