# Hybrid Work Office Sizer

## TL;DR

- Right-size your hybrid office: required desks, [sharing ratio](/topics/hybrid-workplace-strategy), sq ft, and full space-type breakdown.
- Quantifies dollars saved versus traditional 1:1 assigned seating.
- Calibrated to [Class A](/glossary/class-a) space-planning norms.

## Methodology

Peak on-site utilization = days_in_office / 5 + 10% buffer. Sharing tolerance applies a multiplier (low 0.95, medium 0.8, high 0.65). Space breakdown uses Class A norms: 70 sf/desk, 150 sf/private office, ~12 sf/seat collaboration, ~18 sf/seat amenity, plus meeting / phone-booth / circulation. A 22% [loss factor](/glossary/loss-factor) converts net usable to rentable. Traditional baseline assumes 180 sf/person rentable; annual savings = (traditional − hybrid) × rent psf.

## How to use it

- **Enter your headcount** — Total staff and how many of them get private offices.
- **Set the policy** — Days per week required on-site and how comfortable the company is with desk sharing.
- **Add meeting intensity** — Higher meeting load adds meeting room and phone booth area.
- **Review the footprint** — See required desks, sharing ratio, sq ft range, and savings versus traditional 1:1.

## Frequently asked questions

****What sharing ratio is realistic?****
: Most hybrid Class A occupiers land between 1.2:1 and 1.6:1 (people per desk). Heavily flexible cultures push to 2:1+.

****Should I plan for 100% in-office days?****
: No — but build in a 10–15% surge buffer above expected peak attendance to absorb all-hands and team-onsite days.

****Are private offices included?****
: Yes. Exec/private headcount is sized at 150 sf each and excluded from the desk-sharing pool.

****How does this compare to the Office Space Calculator?****
: The Space Calculator sizes for any work style; this tool focuses specifically on hybrid policies and quantifies the savings vs assigned seating.

****Do the savings include fit-out?****
: No — savings are recurring rent only. Smaller footprints also reduce one-time [fit-out](/topics/fit-out-capex)">fit-out capex roughly proportionally.
