En Right sizing and decision support
How do you right-size an office?
Right sizing an office means deciding how many desks and what types of work settings need to work when the office is used under real conditions. It is not a total headcount calculation.
Office sizing goes wrong when organisations count people instead of attendance, variation and activity patterns. That is why an office can be under-dimensioned even when average occupancy looks modest.
The most common simplification is to assume that the average is enough. It is not. If variation is ignored, the office is often designed for a working week that only exists some of the time.
At WeOffice, right sizing starts with evidence about attendance, activities and variation rather than with a target ratio. That is what turns office sizing from a guess into a decision base.
Key takeaways
- Office sizing should be based on actual attendance, variation over time and which settings need to work at the same time.
- Headcount and average occupancy are too weak to use as the only decision base.
- Clean desk policy, activity patterns and normal peak pressure all change how much capacity is needed.
Decision signal
If the organisation is sizing from headcount or average occupancy without understanding normal peaks, variation, and clean desk behaviour, the office is likely to be under-dimensioned.
What does office right sizing mean in practice?
Office right sizing means determining how many desks, meeting settings and other workplace types are required for the workplace to function under realistic demand. It is therefore a question of both quantity and type of capacity.
That matters because desk numbers alone do not define whether an office is usable. Meeting rooms, focus settings and collaboration areas can be under-dimensioned as well. A workplace only works when the settings people actually need are available when demand rises.
Right sizing is therefore not only about how many seats you have. It is about how many people are present, what they need to do when they are there and which settings must hold up at the same time.
For WeOffice, right sizing is part of workplace strategy rather than a late layout adjustment. The sizing decision only becomes robust when it is connected to how work is actually carried out.
Why are headcount, averages and simple occupancy readings not enough?
Headcount is not enough because the whole workforce is not present at once. Averages are not enough because attendance varies between days and often between weekdays. A simple occupancy reading is not enough because it shows how today’s spaces are being used, not necessarily what the future solution will need after a change.
If the office averages 60 per cent attendance but sees much higher levels on certain days, designing for 60 per cent and hoping the rest will sort itself out is a weak decision. The office may feel fine at the end of the week and still fail badly on busier days.
Occupancy is not proof. It is only one signal. A low level of desk use can reflect weak desk placement or poor settings for concentrated work rather than a genuinely low need for ergonomic desk-based work.
Which data do you need in order to size an office properly?
The strongest starting point is attendance data over time, ideally across several months, combined with an understanding of the variation around the average. That is what allows you to size for normal peaks rather than for a fictional average day.
You also need activity analysis, because different tasks require different settings. Work that involves comparing information, processing material and concentrating for longer periods often benefits from properly equipped desk settings. Collaborative work may require different space types altogether.
Occupancy measurement can still be valuable as a complement when you want to understand how existing spaces are currently used. But it should be treated carefully if the organisation is planning a significant shift in workplace model or behaviour.
Four steps to a better sizing decision
- Measure actual attendance over time instead of starting from total headcount.
- Interpret the variation around the average and identify normal peaks.
- Connect attendance to activity patterns and the settings that need to work at the same time.
- Choose a sizing level based on both buffer needs and the behaviours the organisation can realistically sustain.
How does clean desk policy affect the number of desks you need?
Clean desk policy has a bigger impact on office sizing than many organisations expect. The longer people are allowed to leave a desk occupied while away from it, the more desks the office needs if it wants to avoid actual shortage.
That happens because a desk can be unavailable without being used. Someone may spend large parts of the day in meetings, lunch breaks or other activities and still keep the desk blocked. In practice, that sharply reduces effective desk availability even when activity analysis shows that desk work itself only takes part of the day.
This is why clean desk policy needs to be decided before right sizing takes place. If the policy is permissive, the office needs to absorb that. If it is strict, the organisation also needs to be honest about how consistently it will really be followed.
Decision box
A desk that is blocked but unused is still lost capacity. That is why clean desk policy is part of the sizing decision itself, not an afterthought.
How should you think about different sizing levels?
One helpful way to think about office sizing is to choose a sizing level based on both attendance variation and the amount of buffer the organisation wants. A more effective level gives stronger space efficiency but assumes strict behavioural discipline and more use of touchdown options during peaks. A more generous level creates more resilience but requires more space.
The goal is not to find one universal ratio. The goal is to be explicit about which level you are sizing for and which behaviours that level assumes. If the organisation wants everyone to have easy access to desks even on normal busy days, it needs to accept what that means in terms of space and cost.
The right level therefore depends on work patterns, attendance variation, growth expectations, tolerance for crowding and how much movement between zones the workplace is meant to support.
Which misunderstandings most often lead to under-dimensioning?
One common misunderstanding is to treat every empty desk as proof of surplus. Another is to assume that every place where a laptop can be opened should count as an equivalent workstation. That is rarely true for more demanding individual work.
Another mistake is to think meeting rooms and other settings will sort themselves out once desk numbers are right. They may not. Offices are often under-dimensioned because the decision only counts desks and ignores what has to happen around those desks.
Perhaps the most important misunderstanding is to treat right sizing as a layout problem only. In reality, it is a strategic decision about which working conditions the organisation wants to secure over time.
Common misconception
Right sizing is not the same as deciding desk count. The decision also needs to cover meeting rooms, focus settings, collaboration areas and which conditions must hold up on normal peak days.
Next step
If your organisation needs a stronger evidence base around attendance, activity patterns and which settings must work on normal peak days, the next step is to move from assumptions to measurable signals.
FAQ
Is total headcount enough for office sizing?
No. Total headcount is not enough to right-size an office. The workplace needs to be designed around actual attendance, variation over time and the activities that must work when many people are present.
Why is the average not enough?
The average hides variation between days and across the week. If that variation is ignored, the office may look adequate on paper while still failing on the days that matter most.
What is the difference between attendance measurement and occupancy measurement?
Attendance measurement shows how many people come to the office. Occupancy measurement shows how current spaces are being used by those who are there. For sizing decisions, attendance is often the stronger base.
How does clean desk policy change the sizing outcome?
A permissive clean desk policy increases the number of desks you need because desks stay blocked while unused. That is why the policy needs to be decided before the sizing calculation is trusted.
Is right sizing only about desks?
No. Meeting rooms, focus settings and collaboration spaces can be under-dimensioned too. Right sizing is about the capacity of the whole workplace, not only about desk count.
