I Beam Weight Calculator
Estimate prismatic I-section cross-sectional area and weight from flange, web, length, and density dimensions.
Formula
Area = 2 x flange width x flange thickness + web thickness x (overall depth - 2 x flange thickness).
About the I Beam Weight Calculator
Estimate prismatic I-section cross-sectional area and weight from flange, web, length, and density dimensions. This tool keeps the requested measurements separate and applies the named method instead of substituting an unrelated general estimate.
How the I Beam Weight Calculator Works
Section area in square millimeters is multiplied by length and density to obtain mass, then converted to pounds.
Formula
Area = 2 x flange width x flange thickness + web thickness x (overall depth - 2 x flange thickness).
The calculation runs in your browser. Values are validated for required ranges, compatible units, and method-specific restrictions before results are displayed.
Required Inputs

Accuracy and Limitations
Fillets, tapers, rounded corners, holes, coatings, and rolling tolerances are omitted. Use manufacturer section tables for procurement.
Keep units consistent, use measurements that represent the actual situation, retain full precision during the calculation, and round only the final answer. Professional decisions may require current official rules, field measurements, laboratory methods, or specialist review.
