K is limited to 0–0.5. The angle is greater than 0 and below 180 degrees. Flat length uses the outside legs. Local arithmetic only. This is a quantity or geometry estimate, not a code check and not a substitute for a licensed professional.
- Bend allowance
- 0.004178 m
- Bend deduction
- 0.003822 m
- Flat length
- 0.096178 m
Bend allowance = angle in radians × (inside radius + K × thickness). Bend deduction = 2 × (radius + thickness) × tan(angle / 2) − bend allowance. Flat length = outside leg 1 + outside leg 2 − bend deduction.

K is limited to 0–0.5. The angle is greater than 0 and below 180 degrees. Flat length uses the outside legs. Local arithmetic only. This is a quantity or geometry estimate, not a code check and not a substitute for a licensed professional.
Calculate bend allowance, bend deduction and flat length from the angle, radius, thickness and K factor. K is limited to 0–0.5. The angle is greater than 0 and below 180 degrees. Flat length uses the outside legs. Local arithmetic only. This is a quantity or geometry estimate, not a code check and not a substitute for a licensed professional.
A 90° bend, 2 mm radius, 2 mm sheet and K = 0.33.
