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
How to use the Conduit Bending Calculator

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.
