How to Calculate Square Footage of an Apartment
Apartment square footage determines rent pricing, furniture fit, and overall livability. Landlords and tenants alike need accurate measurements.
How Apartments Are Measured
- Measure each room — bedrooms, living room, kitchen, bathrooms.
- Include hallways and closets in the total area.
- Add all areas together for total living space.
Typical Apartment Sizes
- Studio: 300–500 sq ft (28–46 sq m)
- 1-bedroom: 550–800 sq ft (51–74 sq m)
- 2-bedroom: 800–1,100 sq ft (74–102 sq m)
- 3-bedroom: 1,100–1,500 sq ft (102–139 sq m)
Gross vs. Net Square Footage
Gross area includes walls, columns, and shared spaces. Net area (usable space) is typically 15–20% less than gross area. Always ask which measurement a landlord is using.
