Office Space Per Employee Calculator

Work out office space per employee instantly with clear inputs, formula shown and shareable results.

About Office Space Per Employee Calculator

Space per employee should be reported two ways: total usable area per head, which includes meeting rooms and circulation, and workspace area per head. Modern offices run 70-100 square feet per person total, with an increasing share given to collaboration rather than assigned desks.

Formulas

Area per employee

Per person = Total usable area / Employees

Capacity at target

Capacity = Total usable area / Target area per person

Worked example

With the default values below, Office Space Per Employee Calculator returns Total area per employee of 81.8. 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 1 decimal place, 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 density is appropriate?

Around 80-100 square feet per person for a mixed office, 60-70 for a dense open plan, and 150 or more where private offices dominate.

Should hybrid working change the target?

Yes. With desk sharing the relevant denominator is peak attendance, not total headcount, which often releases 20-40% of the floor plate.
