# Hybrid Office Desk Ratio

> A hybrid office should be sized for its peak-day attendance, not its average. Averages hide the busiest days, so desks sized to the average run short on those days and sit empty on the rest. The right desk ratio varies by organisation and should be tested against several weeks of real attendance data.

## The average is the wrong number for a hybrid office desk ratio

Ask most organisations how many people come to the office and you will get an
average: perhaps a rough share of headcount on a typical day. Plan the floor
from that number and it looks efficient. Fewer desks, less area, lower rent.

The trouble is that **hybrid attendance is uneven.** Teams tend to choose the
same days. Some days are busy and others are quiet, and the average sits between
them describing neither. A floor sized to the average has too few desks on the
busy days and too many on the quiet ones.

For a CFO the question is not "how many people are here on average" but "what
does it cost us when the office is full, and what does it cost us when it is
empty." Both have a price, and they are not equal.

## Size for the peak-day, then look at how often it happens

The design question is **peak-day headcount**: the number of people who want a
seat on the busiest day, and how frequently that day occurs.

| Question | Why it matters |
| --- | --- |
| What is the peak-day attendance? | It sets the upper limit the floor must handle |
| How often is the peak reached? | A rare peak may be handled another way, such as booking or overflow space |
| Do teams cluster on the same days? | Clustering pushes the peak up, and staggering flattens it |
| What are people coming in for? | Sets the balance between desks and other space |

Two organisations with the same headcount and the same average attendance can
have very different peaks. A business with a mandated team day has a sharp peak.
One with fully flexible attendance has a flatter profile. The difference is
policy, and it feeds straight into area.

**A peak that happens a few times a year is a different problem from a peak that
happens every week.** The first can often be handled by policy or overflow; the
second needs to be built for.

## Assigned, shared and free address

These are three points on a scale, not three products.

| Model | How it works | What it gives | What it costs |
| --- | --- | --- | --- |
| Assigned seating | Each person has a desk | Familiarity, storage, simple | Most area, empty desks on absent days |
| Desk sharing | A defined group shares a defined pool, often booked | Releases area, keeps some structure | Needs a booking system and clear rules |
| Free address | Any person, any free desk | Most flexibility and area saving | Storage, etiquette and finding colleagues all need designing |

Which suits a role depends on the work. Roles with specialist equipment,
sensitive material or heavy personal storage may need a fixed position. Roles
that move between teams and sites may prefer none.

The commercial trade-off is consistent: **the further toward free address, the
more area is released and the more operating discipline is needed** to make it
work. A shared model with no booking system, or a floor with too few desks and
no overflow, produces frustration rather than savings.

## Test the ratio against data, not opinion

Because the right ratio varies with the organisation, the reliable approach is
to test it against evidence, not to adopt one.

- Gather **several weeks** of actual attendance, from badge or access records, a
  booking system or occupancy sensors.
- Look at the **peak day and how it moves**, not only the mean.
- Check **how much of the day** a desk is actually occupied. A desk booked all
  day and used for an hour is a different case from a busy desk.
- Note **events that distort the sample**: holidays, a policy change, a
  headcount change, a busy season.
- Run the proposed number against the data and see **how many days it would have
  failed.**

If the plan fails on a few days a year, that may be acceptable. If it fails
every week, the ratio is wrong for this business, whatever any benchmark says.
Any figure you see quoted elsewhere is a starting hypothesis, not a rule.

Density in its wider sense, including how area is counted, is covered in our
notes on [workstation density](/glossary/workstation-density) and
[carpet area vs built-up area](/glossary/carpet-vs-built-up-area). Comparing
proposals on area alone is misleading if they measure it differently.

## Fewer desks does not mean less floor

The most common misreading is that a hybrid office is a smaller office. It is
often a **different** office.

If people come in for collaboration, focused work that suits the office better
than home, or to see colleagues, then the space shifts:

- **Meeting rooms** in a range of sizes, often more of them.
- **Focus rooms and phone booths**, for calls and quiet work.
- **Team and social space**, for the reason many people come in at all.
- **Fewer desks per team**, but more flexible ones.

Meeting rooms in particular use a lot of area per person present. So a floor
that cuts desks by a large margin may not release much space once the
meeting and focus provision is added. The
[open-plan versus cabin layout](/compare/open-plan-vs-cabin-office-layout)
question also comes back in a hybrid setting, since acoustic separation matters
more when a floor is full of calls.

## What changes in services

The services design follows the people and equipment in each zone, and a hybrid
office shifts where they are.

- **Power and data** are needed in more places, including bookable desks and
  meeting rooms, and often at higher peak use in the collaboration areas.
- **Cooling and ventilation** respond to occupancy, and a full team day in a
  meeting area is a real load, with ventilation provisions under **NBC 2016,
  Part 8**.
- **Lighting** follows the use of each area, with guidance in **IS 3646**.
- **Escape and occupancy** are set by the layout and the number of people, so
  they belong in the conversation early, with provisions in **NBC 2016, Part 4**.

Whether any diversity can be assumed, meaning that not every desk is used at
once, is a **decision for the project's services engineers**, made explicitly
and documented. It should not be assumed in the layout and discovered later.

## Lease flexibility is part of the answer

A hybrid policy is still changing in many organisations. Sizing a floor tightly
to today's attendance can lock in a decision that the business revises within a
year or two.

Practical protections include a layout that can be reconfigured without major
works, fit-out choices that allow a change of desk density, and, where
possible, lease terms that fit the uncertainty. Our note on
[Cat A versus Cat B fit-out](/glossary/cat-a-vs-cat-b-fit-out) sets out which
elements are fixed and which are flexible, and that split influences how easy
later change is.

## Common mistakes

- **Sizing to the average** and finding the peak-day shortage at move-in.
- **Copying a ratio** from another company or a benchmark without testing it.
- **Using a short data sample**, or one distorted by a holiday or a policy
  change.
- **Cutting desks without adding meeting and focus space**, so the floor works
  for neither.
- **Adopting free address without a booking system** or storage plan.
- **Assuming services diversity** without the engineers agreeing it.
- **Locking the layout** tightly to today's policy.

## What to ask

- What is the peak-day attendance, and how often is it reached?
- What are the actual attendance records for the last several weeks?
- Which roles need a fixed desk, and which do not?
- What will the space released be used for, and how much area does that need?
- Has the services design been told what occupancy it should assume, and has
  that been agreed in writing?
- How easily can the layout change if the policy changes?

## Frequently asked questions

### Why is sizing to average attendance a mistake?

Hybrid attendance is uneven across the week, and averages hide that. If the office is sized to the average, it is short of desks on the busiest days and half empty on the quiet ones. Because the busiest days are often the ones the business most wants the office for, such as team days and client days, the shortage lands where it does most harm.

### Is there a standard desk-to-employee ratio for hybrid working?

There is no ratio that is right for every organisation. It depends on the roles, how attendance is scheduled, how teams cluster on the same days and what the office is for. Treat any quoted ratio as a hypothesis to test against your own attendance records rather than a rule to apply.

### What is the difference between assigned seating, desk sharing and free address?

With assigned seating each person has their own desk. With desk sharing, a defined pool of desks is shared by a defined group, often booked. With free address, anyone can sit at any available desk. Moving along that line usually releases area and raises flexibility, but it adds booking, storage and etiquette needs, and it suits some roles far better than others.

### What data should be used to test a desk ratio?

Several weeks of actual attendance, from badge or access data, booking systems or occupancy sensors, looking at the peak day and how it changes, not only the mean. Include the time of year and any planned change in policy or headcount. A short sample can mislead, especially around holidays or after a policy change.

### If desks go down, where does the space go?

Usually into meeting rooms, small focus rooms, phone booths and social or team space, because the reasons people come to the office are collaboration and separate focused work that home does not suit. Fewer desks does not automatically mean less area, and meeting rooms are often more space-hungry per person than desks.

### Does a lower desk count reduce the building services load?

It can change how services are designed, but not automatically. Power, data, cooling and ventilation are sized on the expected people and equipment per zone, including peak occupancy in meeting and collaboration areas. Whether any diversity can be assumed is a decision for the project's services engineers, and it should be stated explicitly, not assumed.
