As you’re planning the audio requirements for a room – specially your media or entertainment room it would make sense to consider the use of in-ceiling speakers. These speakers

- Minimize clutter,
- Provide a more immersive audio experience and
- Enable more flexibility in your room layout (speakers won’t interfere with furniture for instance)

**How many ceiling speakers do you need?**

This calculator helps find **the number of ceiling mount speakers that are required for a room of any size **(specified in square feet or meters).

Enter

- Height of the ceiling (feet/meters)
- Floor area (ft
^{2}/m^{2})

**Example Calculation**

Consider a room with a ceiling height of 3 meters. A single speaker will cover a diameter of 9 meters and area of 63.6 m^{2}.

If the total floor area of the room is 800 m^{2} then a total of 13 speakers are required.

As the height of the speakers above the floor is increased, the area covered also increases.

**Formulas**

- Diameter of the area that a single speaker covers on the floor
**d = h*3** - Area covered by a single speaker
**A = π*(0.5*d)**^{2} - Total Number of Speakers =
**Floor Area/A**

**How many ceiling speakers are required per square feet?**

The number of speakers required per square feet is **1/A** (where A is the area covered by a single speaker in square feet). In the above example, with a ceiling height of 3 meters, **a single speaker will cover 63.6 m ^{2} or 685 square feet.** In this case, 1/685 = 0.0015 speakers are required per square foot.

## Number of Ceiling Speakers vs Room Area

This table provides the number of speakers required for a room with a certain square footage. The ceiling height is assumed to be 8 feet.

Room Area (Sq. Feet) | Number of Speakers |
---|---|

100 | 1 |

200 | 1 |

300 | 1 |

400 | 1 |

500 | 2 |

600 | 2 |

700 | 2 |

800 | 2 |

900 | 2 |

1000 | 3 |
