How to Choose the Correct Size of Light for a Room

Sep 28, 2025

Lighting is more than just illumination — it defines the atmosphere, scale, and elegance of a space. One of the most common mistakes when designing interiors is choosing a light that’s either too small or too large for the room. At The Lighting Vault, we believe the right size fixture doesn’t just brighten a room, it completes it. Here’s our guide to getting it right.

1. Measure Your Room First

Start with the basics. Add together the length and width of your room (in feet). The total (in inches) is the approximate diameter your ceiling light should be.

  • Example: If your room is 12ft x 14ft, the sum is 26ft. A chandelier or pendant around 26 inches wide will be proportionate.

This formula ensures balance — avoiding a pendant that disappears in a large space or overwhelms a smaller one.

2. Think About Ceiling Height

Scale isn’t just about width, it’s also about drop.

  • For standard 8ft ceilings, choose semi-flush or flush mounts to avoid overcrowding.

  • For higher ceilings, pendants and chandeliers can hang lower — ideally leaving at least 7ft clearance above the floor.

  • In dining rooms or kitchens, lights should hang around 75–90cm above a table or island for both function and impact.

3. Match the Light to the Space’s Function

Consider how the room is used:

  • Dining Rooms: A chandelier should be around half to two-thirds the width of the table.

  • Living Rooms: Statement lights act as a focal point, but balance them with wall lights or floor lamps for layered lighting.

  • Hallways & Entrances: Scale matters here more than ever — a grand chandelier sets the tone for the entire home.

4. Don’t Forget Visual Weight

Two chandeliers can be the same width but look completely different depending on their design.

  • A light with glass rods or crystal details will feel more substantial.

  • A minimalist pendant in the same size may appear lighter and less dominant.
    Balance size with style so the fixture feels right in context with your furniture and finishes.

5. Consider Multiple Fixtures

In larger rooms, sometimes one light isn’t enough. Pendant bars or rows of pendants over an island, or twin chandeliers in a long dining room, can create symmetry and elegance while distributing light evenly.

Final Thoughts

Choosing the right size of light is about proportion, balance, and lifestyle. A fixture should feel integrated into the architecture of the room — not an afterthought. At The Lighting Vault, our collection of hand-picked chandeliers, pendants, and wall lights are available in multiple sizes, so you can find the perfect fit for your space.
