Natural light transforms a home, and few features make as big an impact as a roof lantern. The right size lantern not only brightens your living space but also adds a sense of height, drama, and modern style. But how do you know which size is right for your room?
At The Rooflight Centre, we specialise in helping homeowners bring more light into their homes with beautifully designed roof lanterns. If you’re ready to explore our full range, take a look at our roof lantern collection – or read on for expert advice on choosing the perfect size.
1. Match Your Roof Lantern to Room Size
When selecting a roof lantern, the size of the room should always be your starting point. A lantern that’s too small can look underwhelming, while one that’s oversized may dominate the space and feel unbalanced.
Before: Imagine a large open-plan kitchen-diner with a tiny lantern installed. Instead of making a statement, it looks lost in the ceiling, barely making an impact on light or design.
After: Now picture the same kitchen with a lantern that spans almost the central island. The natural light floods in, the proportions feel right, and the entire space gains a wow factor.
As a general rule, aim for your lantern to cover around one-third of the ceiling space in the room it serves. This keeps the proportions visually appealing and ensures maximum light without overpowering the interior.
2. Consider Ceiling Height and Vertical Space
Ceiling height is often overlooked when choosing a roof lantern, but it makes a big difference. Higher ceilings can handle larger lanterns, as the extra vertical space balances the proportions. Lower ceilings, however, may benefit from something more compact.
Before: A low ceiling with a large lantern frame can feel cramped, making the room seem smaller rather than bigger.
After: A carefully sized lantern that complements the ceiling height creates a sense of airiness, giving the illusion of more space and letting the light do the talking.
Think of your ceiling as the “canvas” – the lantern should enhance it, not overwhelm it.
3. Define Your Lighting Goals
Different rooms demand different levels of natural light. In some spaces, you may want maximum brightness all day, while in others, a softer glow works better.
Before: A snug living room fitted with an oversized lantern may feel too exposed and overly bright, especially in summer months.
After: The same room with a medium-sized lantern provides a cosy atmosphere during the evening while still making the most of daylight hours.
By clarifying your goals – whether it’s creating a sunlit family kitchen, a relaxed lounge, or a bright home office – you’ll be better placed to select the right lantern dimensions.
4. Avoid Common Sizing Mistakes with Roof Lanterns
It’s easy to make errors when sizing a roof lantern, but avoiding these mistakes will save you time, money, and disappointment.
- Going too small: A lantern that’s undersized won’t deliver the dramatic effect you expect.
- Ignoring roof pitch and placement: The shape and slope of your roof determine how much light will filter in. A well-positioned lantern of the correct size will maximise natural light.
- Not planning for furniture layout: If your lantern is directly above a dining table or island, its size should complement the furniture below for a cohesive look.
Before: A homeowner installs a lantern that’s offset and too small, only to find their dining table sits in shadow most of the day.
After: By planning carefully, they choose a wider lantern, centred over the table, creating the perfect illuminated dining zone.
5. Use Real-Life Examples for Guidance
Still unsure? Visualising how others use roof lanterns can help.
- Small rooms (3m x 3m): A 1m x 2m lantern strikes the right balance, brightening the space without overpowering it.
- Medium rooms (4m x 5m): A 1.5m x 3m lantern creates a stunning focal point and floods the room with daylight.
- Large open-plan areas (6m x 8m or more): Multiple lanterns or a single expansive 2m x 4m design can transform the atmosphere.
Before: A homeowner struggling with a dark central kitchen feels restricted to artificial lighting.
After: By installing a roof lantern sized perfectly for the space, the room becomes light-filled and welcoming, reducing the need for artificial lighting during the day.
These examples show how thoughtful sizing decisions directly impact comfort, style, and practicality.
