Strapping Length Calculator

Work out strapping length instantly with clear inputs, formula shown and shareable results.

About Strapping Length Calculator

A vertical strap goes round the length and height, a horizontal strap round the length and width, and each needs about 250 mm extra for the seal, tensioner grip and overlap. Multiplying the average by the number of straps gives the consumption per load and hence loads per coil.

Formula

Strap length

Vertical = 2 x (length + height) + 250 mm; horizontal = 2 x (length + width) + 250 mm

Worked example

With the default values below, Strapping Length Calculator returns Strapping Per Load of 20.200. Change any input above and every figure here is recalculated in your browser.

Assumptions and limits

The result is derived only from the 4 inputs listed above. Anything not among them is not part of the calculation.
In particular, this calculator does not take inflation, tax or compounding frequency into account.
Figures are rounded for display to 3 decimal places, so totals built from several rounded parts can differ slightly from the unrounded arithmetic.
Strapping under tension stores significant energy and can whip on release. Wear eye protection and use the correct cutter when opening strapped loads.

How these calculators are built and tested is described on the Methodology page. If a figure looks wrong, please report it.

Frequently Asked Questions

How many straps does a load need?

Two vertical straps for pallet-to-load locking is the minimum, plus horizontal straps every 400-600 mm of height for tall loads. Edge protectors are needed on compressible loads.

Steel or polyester strapping?

Polyester suits loads that settle, since it retains tension elastically. Steel suits rigid heavy loads needing very high break strength, but loses tension if the load compresses.
