Rebar Calculator — free online calculator.
Formula
- Rebar Calculator calculates its result from Width, Spacing, Length, Total Length, Bar Length. It uses the formula Bars horizontal = ceil(Width / Spacing) + 1; Bars vertical = ceil(Length / Spacing) + 1; Standard bars = ceil(Total length / Bar length). Change any input to recalculate the result instantly.
- The main inputs are Width, Spacing, Length, Total Length, Bar Length. Enter them in the units and format shown in the calculator.
- Keep measurements and project assumptions consistent before comparing or combining values.
- Changing any input above recalculates the result with the same calculation engine used by this page.
Example: Rebar
- Width: 2
- Spacing: 3
- Length: 4
- Total Length: 5
- Bar Length: 6
Using Width = 2, Spacing = 3, Length = 4, Total Length = 5, Bar Length = 6, the calculated result is 1.
