Parts of a fan and their sizes
A ceiling fan has a canopy that covers the hook and the wires, a down rod, a motor housing, blade arms and blades. Each has its own size. The canopy is usually 4 to 6 inches across, the motor housing 7 to 10 inches across and the blade span 36 to 60 inches, depending on the fan.
Typical dimensions by span
These typical ranges help you plan. Always read the maker's specification for your model.
| Item | Typical size |
|---|---|
| 36 inch fan, weight | About 3 - 4.5 kg |
| 48 inch fan, weight | About 4 - 6 kg |
| 56 inch fan, weight | About 4.5 - 7 kg |
| Motor housing diameter | About 7 - 10 inches |
| Canopy diameter | About 4 - 6 inches |
| Blade width | About 5 - 8 inches |
Prices move with brand, model, size and stock. Use these ranges to judge a quote, then compare the exact model and what is included.
Blade width and thickness
Blades are typically 5 to 8 inches wide and a few millimetres thick. Wider blades with a steeper angle move more air but need a stronger motor. Wood and plywood blades are thicker and heavier than metal or plastic. Check the finish for warping, which makes a fan wobble.
Weight and the hook
A 56 inch fan commonly weighs 5 to 7 kilograms, and the load on the hook is higher while it spins. Use a hook rated well above the fan weight and fix it in the slab. Never hang a fan from a false ceiling, a wooden batten or a light hook. See false ceiling fans for fixing details.
Box size and delivery
A packed 56 inch fan box is often about 60 by 25 by 20 centimetres. It fits a rickshaw or a car boot but can be awkward on a narrow staircase. Check the box size if you are carrying it up to a flat, and open it at the door so you can reject damage.
Mounting box and canopy fit
The canopy should sit flat on the ceiling and cover the hook and wires neatly. If the ceiling is uneven or the hook is off centre, the canopy may not cover it. Check the clearance of the canopy against lights and beams before you start. A longer rod needs a longer canopy cover.
How dimensions affect airflow and noise
Blade span, width and pitch together shape airflow. A fan with a poor balance has the same dimensions as a good one but wobbles. Read our guides on ceiling fan length and ceiling fan sizes for choosing the span, and the wattage guide for power.
Checking dimensions before you buy
- Blade span. Matches the room.
- Drop. Matches the ceiling height.
- Weight. Within the hook rating.
- Box size. Fits the route to the room.
- Canopy. Covers the hook and wires.
Fitting
Hang the fan from a hook in the slab and keep blades about seven feet above the floor. Protect the circuit with an MCB. Fixed wiring should be done by a licensed electrician.
