Direct answer
Multiply each room dimension in feet by 0.3048.
For a 12-foot by 10-foot room:
12 x 0.3048 = 3.6576 meters
10 x 0.3048 = 3.048 meters
12 ft x 10 ft = 3.6576 m x 3.048 mUse the Feet to Meters Converter for each room dimension.
How to convert room length and width
- Record the room length in feet.
- Record the room width in feet.
- Multiply the length by 0.3048.
- Multiply the width by 0.3048.
- Write the converted dimensions in the same order.
Do not multiply the length and width together unless you also need the floor area.
Example: convert a 10-foot by 10-foot room
10 x 0.3048 = 3.048 meters
10 ft x 10 ft = 3.048 m x 3.048 mRounded to two decimal places, the room is approximately 3.05 meters by 3.05 meters.
Example: convert a 12-foot by 14-foot room
12 x 0.3048 = 3.6576 meters
14 x 0.3048 = 4.2672 meters
12 ft x 14 ft = 3.6576 m x 4.2672 mRounded to two decimal places, this is approximately 3.66 meters by 4.27 meters.
Example: convert a 15-foot by 20-foot room
15 x 0.3048 = 4.572 meters
20 x 0.3048 = 6.096 meters
15 ft x 20 ft = 4.572 m x 6.096 mCommon room dimensions in meters
| Room dimensions | Metric dimensions |
|---|---|
| 8 ft x 10 ft | 2.4384 m x 3.048 m |
| 9 ft x 10 ft | 2.7432 m x 3.048 m |
| 10 ft x 10 ft | 3.048 m x 3.048 m |
| 10 ft x 12 ft | 3.048 m x 3.6576 m |
| 11 ft x 12 ft | 3.3528 m x 3.6576 m |
| 12 ft x 12 ft | 3.6576 m x 3.6576 m |
| 12 ft x 14 ft | 3.6576 m x 4.2672 m |
| 12 ft x 16 ft | 3.6576 m x 4.8768 m |
| 14 ft x 16 ft | 4.2672 m x 4.8768 m |
| 15 ft x 20 ft | 4.572 m x 6.096 m |
Convert a ceiling height from feet to meters
Ceiling height is a linear measurement and uses the same conversion factor.
| Ceiling height | Meters |
|---|---|
| 7 ft | 2.1336 m |
| 8 ft | 2.4384 m |
| 9 ft | 2.7432 m |
| 10 ft | 3.048 m |
| 12 ft | 3.6576 m |
| 15 ft | 4.572 m |
Convert room dimensions containing inches
Some room measurements contain separate feet and inches. Convert them to total inches or decimal feet before calculating meters.
Example: 12 feet 6 inches
12 feet 6 inches = 150 inches
150 x 0.0254 = 3.81 meters
12 feet 6 inches = 3.81 metersExample room: 12 feet 6 inches by 10 feet 3 inches
12 ft 6 in = 3.81 meters
10 ft 3 in = 3.1242 meters
12 ft 6 in x 10 ft 3 in = 3.81 m x 3.1242 mRoom dimensions versus floor area
Length and width are linear dimensions. Floor area is a separate square measurement.
A 12-foot by 10-foot room has an area of 120 square feet. Converting the two dimensions produces 3.6576 meters by 3.048 meters. Multiplying those metric dimensions gives 11.1483648 square meters.
Do not use the linear factor 0.3048 directly on a square-foot value.
Wall measurements
Convert wall length and wall height separately. For example, a wall measuring 12 feet long and 8 feet high converts as follows:
12 feet = 3.6576 meters
8 feet = 2.4384 meters
Wall dimensions: 3.6576 m x 2.4384 mCalculating paint, wallpaper, or paneling quantities may also require wall area and allowances for doors, windows, and waste.
Room dimensions for furniture planning
Converting room dimensions can help compare them with furniture specifications listed in metric units.
Keep these practical details in mind:
- door swing and doorway width;
- window and radiator positions;
- walkway clearance;
- baseboards and trim;
- built-in cabinets;
- measurement uncertainty;
- furniture assembly clearance.
A unit conversion does not determine whether an item will fit through a doorway or around a corner.
How much should room dimensions be rounded?
Two decimal places are often sufficient for general room comparisons, but detailed planning may require more precision.
Exact: 12 feet = 3.6576 meters
Three decimals: 3.658 meters
Two decimals: 3.66 meters
One decimal: 3.7 meters
The rounding level should reflect the quality of the original room measurement.
Common room conversion mistakes
Converting only one dimension
Convert both length and width when describing a room.
Confusing feet and square feet
Room dimensions are linear, while floor area is square.
Dropping the inch portion
A measurement such as 12 feet 6 inches should not be rounded to 12 feet before conversion.
Rounding too early
Keep the full metric dimensions until the final step.
Assuming converted dimensions guarantee furniture fit
Openings, corners, trim, and installation clearance also matter.
