- Distance between bends
- 12 in
- Multiplier
- 2
- Shrink
- 1.61 in
- Bend angle each end
- 30°
- Add to overall length
- 1.61 in
Quick answer
For an offset, travel = obstacle height × the multiplier for your bend angle (2.0 at 30°, 1.4 at 45°), and shrink is the extra length lost.
travel = depth × multiplier

Frequently asked questions
What is the multiplier for a 30° offset?
2.0 — the distance between bend marks is twice the obstacle depth, with 0.25 in of shrink per inch of offset.
What is conduit shrink?
The length a run loses because the offset travels diagonally; add it to your overall measurement before cutting.
What do I need to enter into the Conduit Bending Calculator?
Just 4 values: bend type, obstacle depth / stub height, bend angle, take-up. Every field starts with a realistic example, so you can change one number at a time and watch the result update instantly.
How does the Conduit Bending Calculator work out the answer?
For an offset, travel = obstacle height × the multiplier for your bend angle (2.0 at 30°, 1.4 at 45°), and shrink is the extra length lost. It applies the formula travel = depth × multiplier and shows the working so you can check each step by hand.
