Square Tube Weight Calculator

Material

Width / OD (in)

Wall / thickness (in)

Length (ft)

Quantity

Enter dimensions, then calculate.

Planning tool only. Verify actual material, manufacturer data, code/WPS requirements and project conditions where applicable.

How it works

Square tubing weight uses outside area minus the hollow inside area. Corner radii are ignored, so use supplier weight for purchasing-critical or engineered work.

Weight = Cross-sectional area × Length × Density

Worked example

A 2 × 2 × .125 in tube is entered as 2 in width and .125 in wall. Enter the stock length and quantity to estimate total weight.

Common mistakes

Use actual outside dimensions and decimal wall/thickness. Nominal sizes, gauge labels and mill corner radii can cause differences.

Frequently asked questions

How accurate is this steel weight calculator?

It is a planning estimate based on nominal dimensions and typical density. Mill tolerances, corner radii and actual alloy can change weight.

Can I use the result for engineered lifting or load ratings?

No. Use certified supplier or mill data and qualified engineering for load-rated work.

What density is used for carbon steel?

The calculator uses about 0.2836 lb per cubic inch for carbon steel.
