About Corrugated Board Requirement Calculator

Corrugated board is bought by area or weight, so the blank size drives the order: area per box is blank length x blank width, uplifted around 4% for trim and make-ready waste. Multiplying by board grammage gives tonnage, which is how the mill invoices.

Formula

Board requirement

Area = blank length x blank width x boxes x 1.04; weight (kg) = area (m2) x grammage (g/m2) / 1000

Worked example

With the default values below, Corrugated Board Requirement Calculator returns Board Weight Required of 9,434.71. 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, fees or charges or compounding frequency into account.
Figures are rounded for display to 4 decimal places, so totals built from several rounded parts can differ slightly from the unrounded arithmetic.

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

Frequently Asked Questions

What is included in the 4% allowance?

Slitting and creasing trim, set-up sheets, and rejects at the printer-slotter. High-graphics or short-run jobs need more, sometimes 8-10%.

Does the blank size include flaps?

Yes. The blank is the flat sheet before folding, so its length spans all four panels plus the glue tab and its width spans the body depth plus both flap sets.
