Definition
Square footage refers to the total area measured in square feet within a property, usually calculated by measuring the length and width of the space and multiplying these dimensions. For buildings, this is typically measured from the outer surface of the exterior walls.
Examples
- Rectangular Home: If a rectangular home measures 40 feet by 50 feet from the outside, the square footage is calculated as follows: \[ 40 \text{ ft} \times 50 \text{ ft} = 2,000 \text{ ft}^2 \]
- Apartment Unit: An apartment unit measuring 25 feet by 30 feet would have a square footage of: \[ 25 \text{ ft} \times 30 \text{ ft} = 750 \text{ ft}^2 \]
Frequently Asked Questions
1. How is square footage calculated for different types of properties?
Answer: For residential properties, square footage is often calculated by measuring the dimensions of each room and summing the areas. For commercial properties, it usually involves calculating the gross leasable area, including common areas.
2. Do basements and attics count in square footage measurements?
Answer: Generally, only finished and livable spaces count towards a property’s square footage. Unfinished basements or attics are typically excluded unless they are fully finished and meet certain standards.
3. Why is square footage important in real estate?
Answer: Square footage is crucial for property valuation, pricing, and comparison. Larger square footage often justifies higher property values and rents.
4. Are there standard methods for measuring square footage?
Answer: Yes, the American National Standards Institute (ANSI) and the International Property Measurement Standards (IPMS) provide guidelines to ensure uniformity and accuracy.
5. Can square footage affect property taxes?
Answer: Yes, larger square footage can result in higher property assessments, which may lead to higher property taxes.
6. Why might square footage reported by sellers differ?
Answer: Variations can occur due to different measurement methods or including/excluding non-livable spaces, which is why independent verification is essential.

### How is the square footage of a rectangular room calculated?
- [x] Length times width
- [ ] Add all walls
- [ ] Length plus width
- [ ] Width minus length
> **Explanation:** The square footage is calculated by multiplying the length by the width of the room.
### Does the measurement of square footage typically include the exterior walls?
- [x] Yes, the measurements are usually taken from the outer edges of the exterior walls.
- [ ] No, it only includes interior space.
- [ ] Yes, but only if the walls are structurally essential.
- [ ] It varies by geographical location.
> **Explanation:** Square footage commonly includes the area measured from the exterior walls unless otherwise specified, like interior-only measurements.
### What areas are generally excluded from square footage in residential properties?
- [ ] Living rooms and kitchens
- [ ] Bedrooms
- [ ] Unfinished basements and attics
- [x] Unfinished basements and attics
- [ ] All rooms with windows
> **Explanation:** Unfinished basements and attics are usually excluded because they are not considered livable space unless finished to a certain standard.
### Why might independent verification of square footage be necessary?

- [ ] The value of the land
- [x] The ratio of total floor area to the lot area
- [ ] The construction timeline
> **Explanation:** FAR indicates the ratio of the building's total floor area to the size of the lot, crucial for zoning and development.
