Calculating Office Space Needs

Determining the right amount of office space requires balancing employee comfort, collaboration needs, and budget constraints.

Space Standards

  • Executive office: 200-400 sq ft per person
  • Private office: 100-200 sq ft per person
  • Open plan: 60-110 sq ft per person
  • Hot desking: 50-80 sq ft per person
  • Industry average: 125-175 sq ft per person (including circulation)

    • Common Area Requirements

    Add 15-25% for common areas:

  • Conference rooms, break rooms, reception
  • Restrooms, storage, utility rooms
  • Corridors and circulation space

    • Hybrid Workforce Adjustments

    With hybrid work, companies can reduce space by sharing desks:

  • A 0.6 sharing ratio means 6 desks for every 10 hybrid employees
  • This can reduce total space needs by 15-30%
  • Consider booking systems and collaboration spaces for in-office days

    • Example Calculation

    25 employees, 150 sq ft each, 20% common area, $28/sq ft rent, 30% hybrid with 0.6 desk sharing ratio.

    1. 01On-site employees: 25 x 70% = 17.5
    2. 02Hybrid employees: 25 x 30% = 7.5
    3. 03Total desks: 17.5 + (7.5 x 0.6) = 22
    4. 04Usable workspace: 22 x 150 = 3,300 sq ft
    5. 05Total with common area: 3,300 x 1.20 = 3,960 sq ft
    6. 06Annual rent: 3,960 x $28 = $110,880
    7. 07Cost per employee: $110,880 / 25 = $4,435
