Bar bending (stirrups) · Engineers, bar benders & students
Calculate stirrup cutting length and number of pieces from column or beam size, clear cover, bar diameter, hooks and spacing—ready for a bar bending schedule.
BBS-ready stirrup length
Cutting length = 2(a + b) + hooks, where a and b are the clear internal dimensions after deducting cover and half the stirrup diameter on each side (site practice often deducts 2×cover + dia). Pair with the [development length calculator](/tools/lap-development-length-calculator) for longitudinal bars.
Your estimate
Stirrup cutting length, count and approximate steel weight for one member.
Out-to-out of stirrup after cover & bar dia
2 × 10φ (90° hooks)
1.428 m
Length/spacing + 2 extras at ends
D²/162 rule
Follow the structural drawing for cover, spacing, hooks and congestion. This is a bar-bending aid, not a design of shear reinforcement.
