Ceiling Fans Buying Guide: Size, Cost and Installation Rules
How to choose ceiling fans in Australia: match fan size to the room, check ceiling height, work out running cost, and know who can legally install one.
A ceiling fan suits rooms where you want moving air without a separate floor or pedestal fan. The main thing to decide is size. One Australian fan maker's size guide matches fan width to the room's floor area, and says the most common sizes are 122 cm and 132 cm. In NSW, installing a ceiling fan is work for a qualified electrician, and Victoria requires a registered electrical contractor for electrical installation work, so plan for one.[1],[2],[3]
How to choose a ceiling fan
Work through these in order, starting with room size.
Match fan size to the room. One Australian maker's size guide suggests the ranges below. Treat them as a starting point, not a rule.[1]
| Room | Suggested fan size |
|---|---|
| Regular room, 7 m² to 13 m²[1] | 122 cm to 132 cm[1] |
| Large room, 13 m² or larger[1] | 132 cm or larger[1] |
| Standard bedroom[1] | Around 122 cm to 132 cm[1] |
| Living room[1] | Often 132 cm to 142 cm[1] |
Check your ceiling height. Measure from the finished floor to the ceiling before you shop, and allow for tiles or carpet. The National Construction Code sets a generally applied minimum ceiling height of 2.4 m for habitable rooms other than kitchens, and 2.1 m for kitchens and laundries. These are room-height minimums, not fan clearance figures, and your own ceiling may be higher or lower, so measure it. Then check the clearance the fan's maker states for the model.[4]
Compare running costs. If a model states its yearly energy use in kilowatt hours (kWh), you can work out a yearly running cost: multiply that figure by your electricity tariff in dollars per kWh. On appliances that carry the Energy Rating Label, the figures come from standardised testing under Australian and New Zealand Standards. They are based on how most people use an appliance, so your actual use may differ.[5]
Plan the installation before you buy. In NSW, installing or replacing ceiling fans, and installing, replacing or moving lights and switches, is work you should never attempt unless you are a qualified electrician. NSW also says DIY electrical work is dangerous and illegal. Victoria requires a registered electrical contractor for electrical installation work. If you live elsewhere, check the current requirements with your state or territory electrical regulator before you book anyone.[2],[3]
In NSW, electricians are required to give you a uniquely numbered Certificate of Compliance Electrical Work. In Victoria, a licensed electrician must provide a Certificate of Electrical Safety when they complete electrical installation work. NSW also makes property owners responsible for ensuring electrical wiring work is done by a licensed electrician.[2],[3]
Ceiling fan questions
What size ceiling fan suits a bedroom?
One Australian fan maker suggests about 122 cm to 132 cm for most standard bedrooms. For a regular room of 7 m² to 13 m², it also suggests 122 cm to 132 cm. Measure your room's floor area first, then compare it against the size ranges above.[1]
What size ceiling fan do I need for a large room?
The same maker suggests 132 cm or larger for rooms of 13 m² or more. For rooms of 13 m² and above, its guide gives a range of 132 cm to 147 cm.[1]
Can I install a ceiling fan myself?
In NSW, installing or replacing a ceiling fan is work you should not attempt unless you are a qualified electrician. Victoria requires a registered electrical contractor for electrical installation work. Check the current rules with your state's electrical regulator.[2],[3]
