Best Salt Lamp Sizes for Your Bedroom

Whether big or small, a Himalayan salt lamp can instantly change the atmosphere of a room while providing a variety of health benefits.


But does the size of a salt lamp really make a difference? And if so, what size is best?

To answer that question, we first need to understand that salt lamps cleanse the air by emitting negative ions which bond with positive ions around it; effectively neutralising and purifying the surrounding environment.

To do this effectively, a salt lamp should be sized in proportion to the room around it to calculate the best size lamp to invest in. Although size isn't the only factor in getting the most out of your lamp, it's the main factor, and the focus of this article. However we do recommend you also read our article how to use a salt lamp in order learn more on how to best use your lamp.

What Size Salt Lamp Do I Need For My Bedroom?

Health Benefits

The size of the salt crystal directly affects the effectiveness of the lamp. Generally speaking, the larger the lamp, the more radiant it is, and the more negative ions it produces.Therefore choosing a salt lamp big enough for the room around it, is essential.

For rooms that measure 3 by 3 meters in size, a salt lamp of around 2 to 3kg is recommended. For a larger room of 4 by 4 meters, the ideal weight of the lamp should be around 5kg.

And so it goes, the larger your room the larger the lamp. Massive spaces such as 10 by 10 meters living rooms, lounges or waiting rooms need a huge salt lamp that weights between 18-22kg to be effective.

If your room doesn’t fall in the above measurements, a good rule to follow is: Add a kilogram of lamp for every 10 square meters of room space.

Two or more smaller lamps can compensate for a large lamp, and can often be more effective if strategically placed around a room.


Another factor to consider when choosing the best size of a Himalayan salt lamp is the illumination. A 5kg to 7kg lamp can cover around 4 to 5 meters radius, and provide ample lighting for most bedrooms.

A lamp of this size is also ideal for pet rooms or any area of your house with strong odours.

Can A Salt Lamp Be TOO Big?

There really is no negative side effects to using a large salt lamp for a smaller room. In fact, it can thoroughly cleanse the air in your room - far more efficiently than a smaller lamp - and provide respiratory benefits.

Quality Himalayan salt lamps that weigh 5 kg or heavier are often difficult to find. When choosing a large lamp, be sure to choose one that’s safety approved by RCM, like our lamps.

Quality lamps usually come with long power cords and extra salt light bulbs for replacement, with prices ranging upwards of $60.

If you can’t find a large salt lamp for your room, an even better option is to buy a few smaller ones to reap the same benefits.

Mini Salt Lamps - Adorable

As large Himalayan lamps can be expensive, a mini salt lamp can be a great substitute for both smaller rooms and budgets. Powered by a mini USB, the lamp gives off a soft and warm glow.

While it does still cleanse and purify the air, it can only effectively work in a small space unless you use more than one mini salt lamp for your room.

Like larger salt lamps, this mini salt lamps are hand-carved from huge chunks of salt crystals. They’re light, portable, and easily cleaned – simply wipe it with a damp sponge.

The smallest can weigh just less than 1kg and stand for only 10 centimetres tall. The heaviest USB salt lamps can get to around 2kg in weight.

The only drawback is that since the smaller bulb generates less heat, it will have less of it’s air purifying effect. However it still makes a great nightlight, and much more natural alternative to led lamps and night lights.
