Why this page exists

Chassis planning gets easier when tube size, wall thickness, length, and material are turned into one weight estimate instead of being looked up or worked out by hand. This calculator helps visitors estimate tubing weight per foot and total tubing weight for a roll cage or chassis project.

Calculator

Roll cage tube weight calculator

Estimate tubing weight per foot and total tubing weight from tube size, wall thickness, length, and material.

Result

255.8 lb

Estimated tube weight per foot and total tubing weight based on tube geometry, total length, and the material selected.

Estimated tube weight per foot2.132 lb/ft

Total tubing weight255.8 lb

Equivalent total tubing weight116.0 kg

Values used1.625 in OD, 0.134 in wall, 120.0 ft, Mild steel

Mild steel tubing at 2.132 lb per foot over 120.0 ft points to about 255.8 lb of total tubing weight.
This estimate treats the tube as straight hollow material based on the outside diameter and wall thickness entered.
Use the result as a planning estimate only, because bends, notching, mounting plates, and material-spec differences can all move finished cage weight.

This is a tubing-planning estimate only. Real finished weight varies with bend length, notching, cutoffs, gussets, mounting plates, and the exact material spec used.

Planning note

Last updated April 16, 2026. Use this tool to compare scenarios and plan ahead, then confirm important details with the lender, employer, insurer, contractor, or other qualified provider involved in the final decision.

How it works

What the calculator is doing

Enter tube outer diameter, wall thickness, total tube length, and material.

The calculator estimates hollow-tube cross-section from the dimensions entered.

It uses the material density to estimate weight per foot and total tubing weight.

Understanding your result

This is a practical tubing estimate, not a finished-cage weight guarantee. Bend length, notching, plates, gussets, and exact material spec can all change the final number.

Examples

Ways people use this tool

Example scenarios help turn a quick estimate into a more useful comparison or planning step.

Compare material choices

Switching between steel-style and aluminum-style density assumptions can show how much total tubing weight may move.

Budget total tubing before fabrication

A rough total weight can help with chassis planning before every bend and notch is finalized.

Check one tubing size against another

Outer diameter and wall thickness changes can move weight faster than many builders expect.

FAQ

Common questions

How is tubing weight estimated here?

The calculator estimates hollow-tube cross-sectional area from outer diameter and wall thickness, then uses length and material density to estimate weight.

Why show weight per foot and total weight?

Weight per foot helps compare tubing sizes, while total weight helps with full-project planning.

Why might finished cage weight differ?

Bends, notching, mounting plates, gussets, and the exact material spec can all shift finished weight away from a straight-tube estimate.
