Choosing the correct Ceiling Fan

Ceiling fans are available in many sizes and styles, with some being more feature rich than others. Be sure that you have the coolest space by reading through this helpful guide.



Be sure to double check the hanging measurements for the particular ceiling fan you choose. Paying attention to these measurements will help ensure you get the best performance from your ceiling fan. Use the diagram below as a reference when measuring your space.

• Silent operation
• Offers more power whilst using less energy
• Most commonly 6-speed options


Ceiling fan performance guide

Air performance (example)
Airflow cubic ft. per minute on high 7587
Power usage Watts on high 34
Airflow efficiency cubic ft. per minute per watt 220

Airflow This is measured in Cubic Feet per Minute (CFM). The higher the airflow number, the more air the fan is circulating.


Power usage The fan motor is measured in watts. The lower the watts, the less energy the fan consumes. DC motor ceiling fans are the most energy-efficient, using the least amount of energy.


Airflow efficiency This gives you the total picture: dividing the fan's CFMs by the watts of power it consumes. The higher the airflow efficiency number, the more air the fan is moving per watt.

Measuring your space

When choosing your ceiling fan, it is important to know the size of your intended space and focus on areas where people are most likely to spend their time. There are some important measurements that you should take in order to choose the correct size ceiling fan. See the diagrams below for more information.



  1. Measure the length and width of your intended space and then multiply together. For example, if your space is 3.7m long by 3m wide, your total area would be 11.1m squared.



  1. Measure the height of your ceiling. There should be a 2.1m clearance between the bottom of the fan blades and the floor.



  1. There needs to be at least 30cm clearance between the tip of the fan blades and any wall or object. If you are using multiple ceiling fans in the same space, then be sure space them at least 1m apart.


Room size Room type Blade sweep Fan size
8m2 Small bedroom 38 - 107cm S
8 - 9m2 Kitchen or porch 38 - 107cm M
9 - 19m2 Dining room 38 - 107cm M
19 - 27.87m2 Outdoor space 38 - 107cm L
Over 27.87m2 Lobby or restaurant 38 - 107cm XL

What is bladespan?

The bladespan refers to the width of the overall fan blades and is essential to picking the right sized ceiling fan for your outdoor space.


The current bladespans available range from 86cm (34in) to 203cm (80in). We suggest using a smaller bladespan for small patios and outdoor porches, whilst a larger bladespan will be perfect for any outdoor alfresco living space.


IP ratings explained

IP ratings are a measure of the protection a sealed (or unsealed) electrical fitting has against dirt or moisture. IP stands for 'Ingress Protection', and its following number codes are defined in international standard EN 60529 (British BS EN 60529:1992, European IEC 60509:1989).


All of our ceiling fans are appropriate for indoor use, however, some are more hardwearing than others. There are many IP ratings that you may need to consider when choosing for your intended space. For example, IP20 (dry) is intended for indoor use only, whilst IP20 (humid) can be used if you have a space with bi-fold doors that integrates with the outdoors. Ceiling fans with an IP23 rating need to be positioned in a fully sheltered space, such as a conservatory, whilst a rating of IP44 can withstand a much harsher environment.

What about blade direction?

Most ceiling fans have a range of speeds and functions. Whether it's a simple 3 speed pull chain like the Kevlar or the 6 speed remote controlled Lehr. However, have you ever paid attention to the blade direction? Ensure you are using your ceiling fan to its full potential.


For summer months, any of the regular fan speeds will give you a tremendous cooling effect. Make sure the blades are rotating in an anti-clockwise direction. In the late summer, when we are still holding on to the last of the lighter evenings, switch the fan into the reverse function. The blades will rotate in a clockwise direction.


This will drive the heat from above the fan downwards to fill the space with warm air, allowing you to fully enjoy those last few alfresco evenings.


Style options

Whether it's traditional finishes or sleek lines, you will find all you need with the new range of ceiling fans from Kichler. For a true industrial feel, the Ahrendale Ceiling Fan is the perfect choice. With an anvil iron finish, anvil mesh and distressed antique grey blades, this product adds the perfect timeworn charm to any outdoor space.


In contrast, the Sola encapsulates a modern style that looks great in or outside of the home. Showcasing sleek blades, an IP23 rating and integrated dimmable LED bulb, this is a great choice for small patios and porches.


All of our ceiling fans have the option for downrods, which are available upon request. If you require more information, please contact our customer service team at customerservies@worm.co.uk or call us on 0345 605 2505.
