If you choose a space that is too small, you’ll need to look for a new one within a year. If you select one that is too large, you’ll pay monthly for empty square feet. Making the right size choice is one of the most practical decisions a business can make and does not involve much guessing. When looking at commercial real estate for lease, here is how to work out exactly what you need before seeing a single space.
Consider the number below as a starting point to improve upon, not as a strict rule. Although every business is different, these guidelines will bring you close to the right answer.
Why Getting Your Commercial Real Estate Square Footage Right Matters
Since space is one of your biggest fixed expenses when leasing commercial real estate, the amount you choose affects your entire budget. Too little space will hinder your team, annoy customers, and force an early move. Too much space ties up cash that could be spent on staff, inventory, or marketing.
The aim is to create a space that is comfortable today while leaving a small margin for tomorrow. This guide will help you achieve that balance.
Start With Your Headcount: Square Footage Per Employee
For office-based companies, the first consideration when looking at commercial real estate for lease is the number of employees. A generally accepted guideline is 150 to 250 square feet per employee in a traditional office. Less space is needed for dense, open-plan designs. Thus, a team of six would need 900 to 1,500 square feet for a comfortable office.
These are approximate figures, not exact, but they provide a realistic starting point. After you have this base, adjust it according to how your business operates.
Adjust for the Type of Business You Run
Not all square footage is used the same way, so your business type matters as much as your headcount:
- Office and professional services generally adhere to the per-employee calculation, together with allowance for meeting space.
- As well as allowing room for the products, the displays, and giving customers space to move around, retail should include the sales floor space in addition to any storage area in the back of the shop.
- Medical and wellness providers usually need exam or treatment rooms, along with a reception and waiting area and accessible layouts, which can add up rapidly.
- The location of service businesses varies all over the map depending on whether customers come to you or you go to them.
Envision a typical day in space and use that to determine how much room each function actually requires.
Factor In Room to Grow
The size that suits your business today could be too small in two years. Before deciding on commercial real estate for lease, consider where the business is headed. Will you hire more people, increase inventory, or expand services during the lease?
It’s good to have some breathing room, but don’t overdo it. Adjust the space size to your realistic short-term plans and choose a lease term that lets you review the situation later. Our guide on buying vs. leasing commercial space explains how flexibility matters in this decision.
Do Not Forget the Support Spaces
It is easy to size only the obvious areas and neglect others. A complete estimate must include all areas that enable a workplace to function.
- Restrooms and a break area
- Storage and supply rooms
- A reception or waiting area
- Hallways and shared circulation space
Adding them up shows that omitting these areas often causes a space that looks right on paper to feel cramped in person.
Common Commercial Space Sizing Mistakes
A few missteps trip up business owners more than any others:
- Sizing only for today and ignoring growth
- Counting only workstations and forgetting support space
- Comparing spaces by rent alone instead of by usable square footage
- Not touring the space to see how the layout actually flows
Avoiding these mistakes will keep your estimate valid when you enter the space.
