Most companies plan their desk count based on gut feeling. The result: either too many empty desks or not enough to go around on peak days. According to the Desk Sharing Index for Germany , the average desk utilization in German offices is just 31%. For every occupied desk, two remain empty. Desk sharing is the answer to this vacancy—but only if the ratio is calculated correctly. This article shows you how the formula works, what a realistic ratio is for hybrid teams, and why Tuesdays and Wednesdays should be the most important figures in your office planning.
Key takeaways
- The desk sharing ratio is the number of desks relative to the number of employees: 0.7 means there are 70 desks available for 100 employees.
- The basic formula is: Desks = Employees x Net Attendance Rate x 1.1 safety buffer.
- For hybrid teams with 2 to 3 office days per week, a ratio between 0.6 and 0.8 is realistic and recommended.
- Tuesdays and Wednesdays account for nearly 48% of all office bookings. These peak days determine your minimum capacity.
What is the desk sharing ratio? And what does it tell you?
The desk sharing ratio describes the relationship between available desks and the total number of employees in the company. A ratio of 0.7 means that for every 100 employees, there are 70 desks available. The lower the ratio, the more efficiently the space is used—and the more success depends on reliable booking rules.
Desk sharing ratio = Number of desks / Number of employees
A ratio above 1.0 means there are more desks than employees, which is the traditional office model. A ratio below 1.0 means multiple employees share a single desk. This works as long as not everyone is in the office at the same time.
For hybrid companies, a ratio well below 1.0 is the goal. It is not a sign of cost-cutting, but a strategic planning tool. More on the Desk sharing basics can be found in our pillar article.
How to calculate the desk sharing ratio: Formula and step-by-step guide
The desk sharing ratio is calculated in two steps: First, determine the net attendance rate of your employees, then calculate the number of desks required. Employees multiplied by the net attendance rate multiplied by a 1.1 safety buffer gives the minimum number of desks. Divided by the total number of employees, this gives you your desk sharing ratio.
Step 1: Calculate the net attendance rate
Subtract all absences from the annual gross working days (approx. 250 in Germany):
- Remote work days (e.g., 40% of the time = 100 days)
- Vacation days (e.g., 25 days)
- Sick days (e.g., 5 days on average)
- Business travel days (e.g., 5 days)
The result is the actual number of office attendance days per employee per year.
Step 2: Calculate the required number of desks
We recommend adding a buffer of around 10%to accommodate peak days:
Desks = Employees x (Attendance days / 250) x 1.1
Calculation example: How to calculate the ratio for 100 employees
Let's look at a concrete example — based on the sample calculation from goconut:
Initial situation: 100 employees, 2 remote work days per week (= 40% remote rate), 25 vacation days, 5 sick days, 5 business travel days.
- Gross working days: 250
- Minus remote work (40%): -100 days
- Minus vacation: -25 days
- Minus sick days: -5 days
- Minus business travel: -5 days
Net office days: 115 days per year
Net office attendance rate: 115 / 250 = 46%
Required desks: 100 x 0.46 x 1.1 = approx. 51 desks
Desk sharing ratio: 51 / 100 = 0.51
This means: 51 desks are sufficient for 100 employees, provided office attendance is evenly distributed. Since this is rarely the case in practice, the next section explains why the peak-day factor is crucial.
What is the right desk sharing ratio?
For hybrid teams with 2 to 3 office days per week, the recommended desk sharing ratio is between 0.6 and 0.8. Planning too low risks bottlenecks and employee frustration. Planning too high means paying for space that goes unused. Maximum occupancy on peak days should consistently stay below 85 to 90%.
Current studies show: A ratio of 0.7 to 0.8 is considered the target range for most hybrid companies. Those offering employees more remote work flexibility can go lower.
Reference values:
- 3 office days/week: ratio approx. 0.7 to 0.8
- 2 office days/week: ratio approx. 0.5 to 0.65
- 1 office day/week: ratio approx. 0.3 to 0.45
According to Owl Labs State of Hybrid Work 2025 , around 54% of German employees currently work in a hybrid model. And according to the PwC study 2025 , employees want an average of 2.77 work-from-home days per week. For space planning, this means that a ratio of around 0.6 is realistic and sustainable for many companies.
Those who also familiarize themselves with the pros and cons of desk sharing or already have a works agreement in mind can incorporate these values directly into their planning.
Why Tuesday and Wednesday are the foundation of your planning
Averages can be misleading. If you only use the average attendance rate, your planning will be too tight—because office presence is not distributed evenly throughout the week.
According to the Desk Sharing Index , Tuesday and Wednesday alone account for 47.7% of all bookings: 24.3% on Tuesday and 23.4% on Wednesday. These two days are the peak days—and they determine the minimum number of desks that must be available.
If you base your desk count solely on the annual average, you will regularly have insufficient capacity on these days. This leads to frustration, competition for preferred spots, and ultimately, rejection of the entire desk-sharing concept.
Our recommendation: First, determine the utilization on your peak days. Plan the number of desks so that utilization on these days reaches a maximum of 85 to 90% is. Only then is the 10% to 15% buffer added on top.
How zone planning in a desk-sharing office is aligned for these peak days is a topic in itself—the crucial point is that team zones and quiet zones must function even on busy Tuesdays.
How OfficeEfficient helps to continuously optimize the ratio
A one-time calculation is not enough. Attendance patterns change with new employees, remote work policies, seasons, and team structures. If you calculate the desk-sharing ratio only at the start and never touch it again, you will lose touch with reality.
The digital workspace booking from OfficeEfficient provides exactly the data needed for ongoing optimization: utilization by day, zone, and floor—in real-time and as historical reports. This allows you to see immediately whether your current ratio is still appropriate or if you should adjust your capacity.
The entire workplace management platform covers not only desks but also meeting rooms, parking spaces, and visitor management. This gives you a complete picture of office utilization—and a sound basis for every decision regarding space optimization.

Conclusion
The desk-sharing ratio is not a one-time figure, but a continuous management tool. By calculating it with the right formula, accounting for peak days, and including an appropriate buffer, you create an office that is efficient while still offering enough space for everyone. For hybrid teams with 2 to 3 office days per week, a ratio of 0.6 to 0.8 is the most realistic target range. And with the right data from a booking system, this ratio can be continuously refined instead of having to be re-estimated every year.
Frequently asked questions
What is a good desk-sharing ratio for hybrid teams?
For hybrid teams that come into the office 2 to 3 days a week, the recommended desk-sharing ratio is between 0.6 and 0.8. This means 60 to 80 desks for every 100 employees. Current recommendations suggest limiting maximum capacity on peak days to 85–90%.
How do you calculate the number of desks needed for desk sharing?
The formula is: employees x net attendance rate x 1.1 safety buffer. The net attendance rate is calculated by taking the total working days and subtracting days spent working from home, on vacation, on sick leave, or on business trips. The result is the minimum number of desks your office should provide.
What happens if the desk sharing ratio is too low?
If the ratio is too low, bottlenecks will occur on peak days. Employees won't be able to find a seat, will have to look for alternatives, or will simply stop coming into the office as often. This jeopardizes the acceptance of the entire desk sharing concept. As a rule of thumb: if peak-day occupancy is consistently over 90%, capacity should be increased.
How often should you review the desk sharing ratio?
At least once a quarter, ideally monthly. Attendance patterns change with team size, remote work policies, and seasonal factors. A digital booking system that automatically tracks occupancy data makes this review process effortless, eliminating the need for manual surveys.
Can the desk sharing ratio vary by department?
Yes, and in practice, this is highly recommended. Departments with a high preference for remote work can be planned with a lower ratio than teams that require a strong office presence. Zone-based planning allows you to set individual ratios and booking rules for each area.
