Calculate a joggle
A joggle offsets two parallel faces relative to each other with two opposite bends close together — handy for an overlapping weld or snap joint. Calculate the required angle or offset below.

The formula
A joggle consists of two bends with the same angle but opposite direction, with a straight run (the "riser") in between. The offset between the two parallel faces follows a simple triangle relationship:
offset = riser length × sin(angle per bend)
Prefer to start from a desired angle instead of an offset? This tool works the same formula the other way round.
How long should the riser be?
Too short, and the distortion zones of the two bends overlap. As a rule of thumb:
| Riser length | Guidance |
|---|---|
| < 1 × thickness | Not recommended |
| 1 × thickness | Tightest achievable riser |
| 2 × thickness | Common, safe choice |
Use the "1 × t" and "2 × t" quick buttons to tie the riser length directly to the entered thickness. This remains a rule of thumb — for a borderline case, a test bend remains the only certainty.
