Stocking Density Calculator

Work out stocking density instantly with clear inputs, formula shown and shareable results.

About Stocking Density Calculator

Expresses stocking density by head and by live weight per square metre, the measure most welfare codes regulate.

Formula

Stocking density

Animals per m2 = animals / area; density by weight (kg/m2) = animals per m2 x average live weight

Worked example

With the default values below, Stocking Density Calculator returns Stocking density by weight of 1.100. Change any input above and every figure here is recalculated in your browser.

Inputs used

Animals housedaccepts 1–1,000,000: 500
Available floor areaaccepts 0.1–1,000,000 m2: 1,000 m2
Average live weightaccepts 0.01–1,500 kg: 2.2 kg

Results

Stocking density by weight: 1.100 kg/m2
Animals per square metre: 0.5000
Floor area per animal: 2.0000 m2
Floor area per animal: 20,000 cm2

Assumptions and limits

The result is derived only from the 3 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

Why regulate by weight rather than head?

Birds and animals grow, so a fixed head count becomes progressively more crowded; weight-based limits track the real space need.

What limits apply to broilers?

EU rules cap most systems at 33 kg/m2, rising to 39 or 42 kg/m2 only with additional welfare conditions.
