Rebar Weight Calculator

Decision support

What this tool helps you decide

Best for

Weight and handling planning after bar size and length are known.

Enter

Bar size, count or length and the selected steel unit weight.

You get

Estimated total linear length and weight for transport or purchasing.

Check before buying

Verify the bar designation, stock lengths, bundle limits and structural schedule.

What you will get

1. Needed

See the estimated project quantity from your measurements.

2. Buy

Add waste and round to complete bags, boxes, cans, bundles or delivery quantities.

3. Check

Review product coverage, site conditions, local requirements and supplier details before ordering.

Quick answer: Calculate reinforcing bar total length and approximate weight using common US bar sizes or metric diameters. Start with actual measurements, use the product label for coverage or yield, and treat the result as a planning estimate until site conditions and supplier requirements are confirmed.

Transparent formula

How rebar weight is calculated

US bar sizes use published nominal weights in pounds per foot. Metric bars use the common theoretical relationship based on diameter squared.

total weight = bar count × length × unit weight
metric kg/m ≈ diameter² ÷ 162

Planning only: this tool estimates material weight. Bar size, spacing, laps, hooks, cover and reinforcement design must come from the project drawings and applicable local requirements.
