A 10x12 room is 120 square feet.
A 10x12 room measures 10 feet in width and 12 feet in length, resulting in a total area of 120 square feet. This is calculated by multiplying the width (10 feet) by the length (12 feet), which gives you the total square footage of the room.
How to calculate square footage for different room dimensions
- Measure the length and width of the room in feet
- Multiply length × width to get square footage
- For irregular rooms, divide into rectangles and sum areas
- Round measurements to nearest foot for simplicity
Comparison of common room sizes and their square footage
| Room Dimensions | Square Footage | Typical Use |
|---|---|---|
| 10×10 | 100 sq ft | Small bedroom, office |
| 10×12 | 120 sq ft | Medium bedroom, guest room |
| 12×12 | 144 sq ft | Large bedroom, living room |
| 12×15 | 180 sq ft | Master bedroom, family room |
Factors affecting square footage calculations
- Include closets and alcoves in measurements
- Subtract non-usable spaces like built-in cabinets
- Account for wall thickness in architectural plans
- Consider ceiling height for volume calculations
