Desk sharing: how to set the ratio, the rules and the software
Desk sharing means fewer desks than people — but desks that match how people actually work. This guide shows how to calculate your sharing ratio, which rules create acceptance, and what a desk booking system needs to deliver.
Overview
Desk sharing (also called hot desking or flex office) removes fixed desk assignments: people book a free workstation for the day. In hybrid teams offices often run at only 40 to 60 percent occupancy — desk sharing turns that gap into usable space instead of paid-for emptiness.
The key lever is the sharing ratio: desks per employee. With an average of three office days per week, a ratio of 0.7 to 0.8 usually works — 70 to 80 desks for 100 people. What matters is the peak day, not the average: if everyone comes in on Tuesday and Wednesday, either the ratio absorbs that peak or attendance rules flatten it. The number only becomes reliable with real occupancy data rather than booking intentions.
Desk sharing rarely fails on technology; it fails on missing ground rules. Where do I keep my things? Will my team sit together? What if nothing is free? Every rollout therefore needs a clear rule set (booking window, no-show rule, team zones, clean desk, lockers), works-council involvement, and honest communication about why the change is happening.
Compliance still applies: shared desks must meet German workplace regulation (ArbStättV) and occupational safety law (ArbSchG). Height adjustment, monitor, lighting and ergonomics cannot depend on which desk someone grabs in the morning — and home-office days require their own risk assessment plus proper equipment.
Software is the enabler. A desk booking system shows free seats on the floor plan, models team zones, combines desk, room and parking bookings, and produces the utilization data for your next space decision. onyo pairs that desk booking with equipment for both office and home office — one provider for both sides of hybrid work.

Frequently asked questions
What exactly is desk sharing?
With desk sharing there are no fixed desks. Employees book a free workstation for the day, usually via a desk booking app. Personal items live in lockers and the desk is cleared in the evening (clean desk).
Which sharing ratio makes sense?
As a guide: around 0.5 to 0.6 desks per person at two office days a week, 0.7 to 0.8 at three days, 0.9 at four. The peak day decides, not the average — so validate the ratio with at least four weeks of real occupancy data.
Is desk sharing legally allowed?
Yes. There is no entitlement to a specific desk. But workplace regulation and occupational safety law still apply: every shared desk must be ergonomically suitable. In Germany the rollout is also subject to co-determination — involve the works council under § 87 BetrVG.
How do employees react to desk sharing?
Acceptance comes from choice and reliability: team zones where colleagues sit together, enough focus and retreat rooms, sufficient lockers, and a guarantee that booked desks are actually available. If space is simply cut without improving the work environment, sentiment turns.
What does desk sharing cost — and what does it save?
The main benefit is space cost: in major German cities a workstation costs roughly EUR 4,000 to 8,000 per year depending on location. Cutting 20 percent of desks usually pays for booking software, lockers and better home-office equipment several times over.
What software do you need for desk sharing?
A desk booking system with floor-plan view, team and zone logic, calendar integration, a mobile app, no-show handling and utilization reporting. Ideally it also covers rooms and home-office days, so you see the full hybrid week.
How do you roll out desk sharing?
Five steps work well: 1. measure occupancy, 2. set the sharing ratio and zone concept, 3. agree rules and a works agreement, 4. pilot with one team on one floor, 5. adjust after eight to twelve weeks based on the data and roll out.

Short, reliable answers from our knowledge base.
How much office space does hybrid work save?
In practice, hybrid work and desk sharing typically save 20–40% of office space and therefore rent. Fewer desks needed means less space – how quickly the saving materialises depends on the lease.
Read answerHow does a desk booking system work?
Employees select an available desk for a given day. Depending on the system they see a floor plan, team zones or utilisation. Bookings generate planning data – they evidence the booking, not necessarily actual attendance.
Read answerWhat is desk sharing?
Desk sharing means not every person has a permanently assigned desk. Employees use or book available desks. Typical ratios reduce desks, office space and rent by 20–40%.
Read answerWhat is a clean desk policy?
A clean desk policy requires desks to be left free of personal and confidential material at the end of the day. This makes desk sharing easier and is a building block of data protection – on its own it is not a sufficient data-protection measure.
