What Size Rooflight Do I Need for My Extension?
Choosing the right rooflight size for an extension is a decision that affects how the finished room looks, feels and performs for years to come. An extension rooflight is often the main source of natural light in the room and the size you choose determines how much of that light reaches the space below. A rooflight that is well matched to the extension makes the space brighter, more comfortable and far more enjoyable to use throughout the day.
How Your Extension Layout Affects Rooflight Size
The layout of your extension is the best starting point when deciding on size. A kitchen extension where you cook and spend time with family needs good overhead light across the area where most of the activity takes place. A dining or living space benefits from a rooflight that covers the table and seating area so the light spreads evenly across the room.
Where you spend the most time in the room is where the rooflight should be positioned. That single decision will shape how much light the room receives and how the space feels day to day.
Positioning Your Rooflight for the Best Result
A well-positioned rooflight makes a real difference to how the room feels. In a kitchen extension, positioning it above the island or worktop brings light directly where you need it most. In a dining or living area, placing it above the table or main seating area makes the room feel naturally brighter and more welcoming throughout the day.
Once the position is decided, the right size follows more easily. The position and size work together to give you the best result from your rooflight.

A single rooflight works well where the extension has one main area of use. It creates a strong visual presence overhead and brings a wide spread of light into the room. For longer or L-shaped extensions, two rooflights placed at different points across the ceiling provide a more balanced spread of light and are an effective way to brighten an open-plan extension evenly.
Your installer can recommend the best arrangement based on how your extension is shaped and how the room will be used.
Standard and Bespoke Sizes for Extension Roofs
Most extensions have flat roofs, which makes fitting a rooflight a simple process. A wide range of ready-made rooflights is available and these suit the majority of extension projects. Where the roof does not match a standard option, bespoke rooflights are manufactured to your exact measurements for a precise fit.
Ready-made sizes ship quickly, which helps keep your project on schedule. Bespoke sizes allow you to match the rooflight to your roof exactly for a result that looks right from every angle.
Roof Lanterns as an Option for Larger Extensions
If your extension has the ceiling height for it, a roof lantern brings light in from more than one angle and adds extra height and space to the room. They suit larger kitchen extensions and open-plan dining areas particularly well and have become one of the most popular rooflight trends in modern home design.
A roof lantern is available in a range of sizes and your supplier can help you choose one that works for your extension and ceiling height.
Choosing the Right Rooflight Size for Your Extension
The right size comes down to your extension layout, the room it serves and how you plan to use the space. A rooflight that is well matched to the room brings in the right amount of light, fits the roof properly and makes the extension a brighter and more comfortable part of your home.
Your installer or rooflight supplier can advise on the best option for your project before you order.
