Stirrup Cutting Length & Bar Bending Schedule Basics
Calculate stirrup cutting length for beams and columns from section size, cover, hooks and spacing—plus how it fits a bar bending schedule.

Site searches for stirrups cutting length calculator and BBS come from bar benders and junior engineers who need a reliable formula under time pressure.
Open the Stirrup Cutting Length Calculator. Cutting length ≈ 2(a + b) + hooks, where a and b are clear internal dimensions after cover and bar diameter deductions. Pair longitudinal bars with the Ld & lap length calculator.
Hooks: 90° vs 135°
Ordinary detailing often uses 90° hooks (~10φ each). Seismic detailing commonly requires 135° hooks (~12φ each). Always follow the structural drawing over a rule of thumb.
From one stirrup to full steel weight
- 1Count stirrups from member length ÷ spacing (+ extras at ends).
- 2Multiply by cutting length for total metres.
- 3Convert to kg with D²/162, or use the steel rebar weight calculator.
