What Size Reed Diffuser for My Room? A Guide by Rosemary Jane UK

Reed diffusers are a simple yet stylish way to keep your home smelling beautiful all day, every day. Unlike candles or electric diffusers, reed diffusers don’t require a flame or power source—just pop in the reeds and enjoy long-lasting fragrance. But when it comes to choosing the right size for your space, things can get a little confusing.

At Rosemary Jane UK, we believe fragrance should be effortless—and that includes selecting the perfect diffuser. So, if you’re wondering what size reed diffuser is best for my room, we’ve put together this guide to help you find your scent-sational match.

Why Size Matters

It’s not just about aesthetics. The size of your reed diffuser directly affects how far the scent travels, how strong it is, and how long it lasts. A diffuser that's too small for a large room may leave you underwhelmed, while one that's too large for a small space might feel overpowering.

So, how do you find the perfect balance? Let’s break it down.

Room Size vs. Diffuser Size

Here’s a simple guide to help match diffuser sizes with room sizes:

Room Size Suggested Diffuser Size Typical Room Examples
Small (under 10m²) 50–100ml Cloakroom, ensuite, small hallway
Medium (10–20m²) 100–150ml Bedroom, bathroom, small office
Large (20–30m²) 150–200ml Living room, kitchen-diner
Extra-Large (30m²+) 200ml+ or multiple smaller diffusers Open-plan living spaces, large halls

Tip: For large or awkwardly shaped rooms, two smaller diffusers placed strategically often work better than one oversized diffuser. This allows the scent to distribute more evenly across the space.

The Role of Reed Quantity and Length

The reeds are the heroes of the diffuser world. They draw up the fragrance oil and disperse it into the air. But it’s not just a case of ‘the more, the merrier’.

How Many Reeds Should I Use?

  • Small diffusers (50–100ml): 4–6 reeds

  • Medium diffusers (100–150ml): 6–8 reeds

  • Large diffusers (150ml+): 8–10 reeds

Adding more reeds increases the intensity of the fragrance, but also means the oil will be used up faster. If you prefer a lighter scent or want to make it last longer, use fewer reeds to start, then add more as needed.

What About Reed Length?

Reeds typically range from 20cm to 30cm in length. Longer reeds are best for larger bottles, as they have more surface area to disperse the scent. Just make sure the reeds are proportionate to the bottle height—if they’re too short, the scent throw will be limited; too long, and they may topple over or look awkward.

Placement is Everything

Even the best diffuser won’t perform well if it’s hidden behind a curtain or stuck in a draughty corner. Where you place your reed diffuser has a big impact on how well the scent circulates.

Best Practices for Placement:

  • Keep it at nose level: Whether that’s on a shelf, side table, or bathroom unit, try to place the diffuser where it’s in the natural airflow and within the breathing zone.

  • Avoid direct sunlight and heat sources: These will evaporate the oil too quickly and reduce longevity.

  • Use high-traffic areas: Placing your diffuser in places where people walk through often—like hallways or entryways—helps to naturally distribute the scent.

  • Don’t block the reeds: Avoid placing the diffuser behind furniture or near vents where air might carry the scent away from the room.

Making the Most of Your Diffuser

To keep your reed diffuser working its best:

  • Flip the reeds regularly – Every 1–2 weeks is ideal. This freshens up the scent.

  • Use fresh reeds – If you’re refilling the bottle, always replace the reeds. Old reeds can get clogged and lose effectiveness.

  • Clean your bottle between refills – A quick rinse with warm soapy water prevents mixing of old and new fragrances.

FAQs 

Q: Can I use fewer reeds in a large diffuser?
Yes, using fewer reeds will reduce the intensity and make the diffuser last longer. It’s a great way to control the fragrance strength.

Q: How long do reed diffusers last?
Typically between 2–4 months, depending on the room temperature, air circulation, and number of reeds used.

Q: Can I reuse reeds?
Not recommended. Reeds get clogged over time, which reduces their effectiveness. Always use fresh reeds when refilling.

Q: Why can’t I smell my reed diffuser anymore?
Try flipping the reeds, moving it to a better location, or adding a few fresh reeds. If it still doesn’t help, the oil may be used up or the reeds may be saturated.

Q: Are Rosemary Jane UK diffusers refillable?
Yes! We offer eco-conscious refills so you can top up your favourite scent without needing to buy a new bottle each time.
