Calculate the quantity, length and approximate weight of reinforcing bars. You can also estimate reinforcement distributed by spacing for slabs, walls and other surfaces.
Calculate rebar quantity, total length, approximate weight and steel required for slabs, walls, beams and other elements.
For individual bars, multiply the quantity by the length of each piece.
For reinforcement distributed by spacing, the quantity depends on area dimensions, bar spacing, directions and the number of layers.
Total weight is calculated using the theoretical weight per meter for the selected bar diameter.
General formula
Weight = total length × kg per meter
Multiply the total bar length by the weight per meter corresponding to the selected diameter.
Divide the transverse dimension of the area by the spacing and add one bar to cover both edges.
An initial allowance of 5% to 10% is common, although the actual value depends on cuts, lap splices, anchorage and project geometry.
No. It provides material estimates only. Reinforcement design must be completed by a qualified professional.
