How to Use This Calculator
- Enter Total area (sq ft), Space type (0-5), and Planned occupants.
- Set ADA required (0/1), Density (0=generous, 1=standard, 2=dense), and Circulation (%).
- Review Maximum capacity and Area needed - gross (sq ft).
- Use Sq ft per person (standard) and Net usable area (sq ft) to inform your decision.
How the result changes with Total area (sq ft)
| Total area (sq ft) | Maximum capacity | Area needed - gross (sq ft) |
|---|---|---|
| 50,045 | 547 | 1,829 |
| 175,033 | 1,914 | 1,829 |
| 325,018 | 3,554 | 1,829 |
| 450,005 | 4,921 | 1,829 |
What each input means
- Total area (sq ft)
- Gross floor area available for the space.
- Space type (0-5)
- 0=private office, 1=open workstation, 2=conference, 3=reception, 4=break room, 5=library.
- Planned occupants
- Number of people to accommodate.
- ADA required (0/1)
- 1 = ADA-compliant clearances required.
- Density (0=generous, 1=standard, 2=dense)
- Space allocation preference per person.
- Circulation (%)
- Percentage of floor area dedicated to aisles and circulation.
What each result means
- Sq ft per person (standard)
- Space allocation per person based on type and density.
- Net usable area (sq ft)
- Usable area after subtracting circulation.
- Maximum capacity
- Maximum people the space can accommodate at selected density.
- Area needed - gross (sq ft)
- Total gross area needed for planned occupants.
- Area surplus/deficit (sq ft)
- Positive = surplus space, negative = insufficient space.
- Primary aisle width (in)
- Main circulation aisle width requirement.
- Secondary aisle width (in)
- Secondary/branch aisle width requirement.
- ADA accessible stations
- Minimum ADA-accessible workstations required (5% of total).
- Density rating (0-3)
- 0=overcrowded, 1=dense, 2=standard, 3=generous.
- Furniture zone area (sq ft)
- Area available for furniture placement.
How this is calculated
Worked example, using the default values
- Identify Input Parameters4 parametersTotal area (sq ft) = 2000, Space type (0-5) = 1, Planned occupants = 20, ADA required (0/1) = 1 = 6 input(s) provided
- Calculate Maximum capacityMaximum capacity21 = 21
- Calculate Area needed - grossArea needed - gross = areaNeededNet / (1 - circulationPct / 100)1829 = 1829
- Calculate Sq ft per person64 = 64
- Calculate Net usable areaNet usable area = totalAreaSqFt * (1 - circulationPct / 100)1400 = 1400
