Aluminium rooflights are an excellent way to brighten up your living space by letting in natural light and providing ventilation. Whether you’re looking to install them in a loft conversion, an attic, or even in an extension, choosing the right size roof light is crucial to achieving the desired effect and functionality. But with so many options available, you might be wondering: What size rooflights can I buy?

In this guide, we’ll explore the different sizes of roof lights available, what factors to consider when choosing the size, and how to ensure your new roof windows fit perfectly within your space.

Standard Rooflight Sizes

So, what size rooflights can you buy?

At Lantern Superstore, our Rooflights come in a variety of standard sizes to accommodate different needs and personal preferences. These sizes are typically based on the window’s width and height, with common measurements ranging from small, space-saving options to larger designs.

Here are some typical standard sizes you can find:

• Small Rooflights: Ideal for compact spaces, bathrooms, or areas where only a modest amount of light is needed throughout the day. Square rooflights can suit a square room or corridor perfectly, with circular rooflights offering a unique spotlight feature.
  • 600mm x 600mm
  • 750mm x 750mm
  • 900mm x 900mm
  • 1000mm x 1000mm
  • 1050mm x 1050mm
• Medium Sizes: Suitable for most rooms, providing a good balance of light and ventilation.
  • 900mm x 600mm
  • 1200mm x 600mm
  • 1200mm x 900mm
  • 1200mm x 1200mm
• Large Sizes: Perfect for creating a bright, open feel in larger rooms or loft spaces with more light.
  • 1350mm x 1350mm
  • 1500mm x 1000mm
  • 1500mm x 1500mm
  • 2000mm x 1000mm
  • 2000mm x 2000mm

These measurements can vary slightly depending on the manufacturer, but at Lantern Superstore we can cater for a huge array of sizes with our flat rooflights. Additionally, our manufacturers also provide custom sizing options to meet specific design requirements or fit unusual spaces. Some of these sizings can reach up to 2850mm x 1650mm.

Considerations for Choosing the Right Size of Aluminium Rooflight

Selecting the right size aluminium roof light involves more than just measuring the available space. Here are some key factors to consider before you purchase your new rooflight:

1. Room Size and Ceiling Height

The size of the room and the height of the ceiling are crucial factors when choosing roof windows. Larger rooms can accommodate bigger windows, which will maximise the amount of natural light entering the space. For rooms with higher ceilings or pitched roofs, consider windows with greater height or length to ensure the light reaches deeper into the room. You may also want to explore our range of roof lanterns for home with higher ceilings, as these can help bring light further into a room due to their pitched projection.

2. Functionality and Purpose

Think about what you want your new aluminium rooflight to achieve. If your primary goal is to increase natural light, multiple, large windows might be the best option for your living space.

For ventilation purposes, consider how easy it will be to open and close the windows. In some cases, you might prefer smaller, rooflights that open in combination with fixed, larger panes. Our range of Brett Martin aluminium rooflights are available in both manual and powered opening options, which are ideal for those looking for a well-ventilated solution. You might also want to consider how easy it will be to clean your rooflights depending on their size.

3. Roof Pitch and Structural Constraints

The pitch (angle) of your roof will also influence what size rooflights you can install. Some sizes and styles are better suited to specific roof pitches, so be sure to check the manufacturer’s recommendations. Additionally, consider any structural constraints, such as the placement of rafters or beams, which may limit the size of the window you can install.

To find out more about the pitch requirements for our products, check out our useful help and guides page, with all the information you need to know before installing a rooflight.

4. Building Regulations

Before deciding on the size of your roof window, it’s essential to check local building regulations. These rules can dictate the maximum size of windows, especially in conservation areas or listed buildings. Some areas may have restrictions on how much of the roof space can be replaced with glazing, or they may require specific materials to maintain the aesthetic of the area.

You should always do this prior to any development work on your property, to avoid any conflict resulting in you needing to take your constructions down. In some instances, you may need to apply for planning permission for a roof lantern.

Custom Roof Window Sizes

If standard sizes don’t suit your needs, at Lantern Superstore, we also cater for custom sizings. Custom rooflights can be tailored to fit unique spaces or to achieve a specific design vision. This option is particularly useful for irregularly shaped rooms, or when integrating the window into an existing structure where standard sizes won’t fit.
