How to use the Rebar Cutting Length Calculator

- Leave the deduction blank for 2 × diameter, or type the deduction from your schedule.
Questions
What is the deduction?
It is the length you take off for each bend so the cut bar matches the out-to-out shape. A blank field uses 2 × diameter. That is a shop allowance, not a code rule.
Can I enter a straight bar?
Yes. One leg and zero bends returns that leg as the cutting length.
