Office space per person

It’s generally accepted to allow approximately 100 sq ft per person. This is based on 50 sq ft per desk in an open plan environment, and 50 sq ft towards communal areas, such as meeting rooms, kitchens and break out spaces. If your work environment is cubicle based, allow 100 sq ft per cubicle.

In areas where office space is expensive companies have been known to reduce space per person to around 70 - 80 sq ft. Alternatively depending on the environment you wish to create, and if budgets allow, you may want to consider increasing above the standard 100 sq ft per person.

How much office space will I need?

While the above provides a helpful starting point when beginning your office space search, it’s important to consider a range of factors which will impact the amount of space you require. There isn’t really a standard office size that exists, even for companies with similar numbers of employees, as many things affect how much space is required.

Things to consider when calculating office space include

  • Company plans - are you likely to be increasing the number of employees, or downsizing?
  • How many employees work remotely
  • How far employees will be situated from natural light
  • How many meeting rooms and communal spaces you require - will this change as the business changes?
  • What sort of environment do you want to create?
  • The shape of the space - there may be unusually shaped spaces that will be difficult to use effectively.

An architect or space consultant can help advise you on the best use of the space, and we’d recommend you liaise with them before signing a lease.
