Dimensions at a Glance
I can’t tell you how many times I’ve watched someone fall in love with a diffuser online, only to have it arrive and completely overwhelm their space—or worse, look like a tiny toy lost on their coffee table. The Brevi essential oil diffuser has become one of my go-to recommendations because it hits that sweet spot of being perfectly sized without sacrificing performance.
The Brevi Stone Diffuser from doTERRA measures exactly 12.5 cm (4.9 inches) in diameter and stands 8 cm (3.15 inches) tall. What makes this ultrasonic diffuser so appealing is how it manages to pack serious misting power into such a compact, elegant design. With its marble-inspired finish and circular shape, it’s the kind of aroma diffuser that actually enhances your space rather than cluttering it.
Core Specifications: Brevi Diffuser Dimensions and Capacity
Let me break down the exact dimensions of the Brevi essential oil diffuser because these numbers really matter when you’re trying to figure out placement. The diffuser dimensions are surprisingly compact—that 4.9-inch diameter means it’ll fit comfortably on most nightstands, desks, or side tables without dominating the space.
The water capacity is 120 mL (4 fluid ounces), which might sound small, but here’s what I love about this size: it’s perfect for personal use without requiring constant refills. The coverage area extends up to 270 square feet, which means this little powerhouse can effectively scent a medium-sized bedroom, home office, or cozy living area.
What really sets the Brevi apart in terms of functionality is its dual operational modes. You can run it for 5 hours continuously or switch to the 10-hour intermittent cycle that runs 5 minutes on, 5 minutes off. The LED lighting system offers four color options—blue, purple, yellow, and warm white—with both cycling and static modes.
Comparative Size Analysis
I’ve tested dozens of diffusers over the years, and the Brevi’s size positioning is quite strategic. Most ultrasonic diffusers on the market range from 10 cm to 30 cm in diameter, so the Brevi’s 12.5 cm diameter places it in the smaller-to-midsize range—ideal for personal use without being too tiny to be effective.

Here’s how the Brevi diffuser size comparison stacks up against typical market options:
- Size: Brevi at 12.5 cm × 8 cm vs. typical range of 10-30 cm diameter
- Mist Coverage: 270 sq. ft. compared to the 100-500 sq. ft. range of most diffusers
- Runtime: 5-hour continuous or 10-hour intermittent vs. standard 2-8 hours continuous
- Design: Sleek marble-inspired finish vs. bulkier plastic models
The beauty of the Brevi’s dimensions is that it doesn’t sacrifice mist output for compactness. While some smaller diffusers struggle to fill even a small room, this one confidently handles spaces up to 270 square feet.
Ideal Placement by Room Size
The question “will the Brevi diffuser fit on a small nightstand?” comes up constantly, and the answer is absolutely yes. At just under 5 inches in diameter, it’s perfectly sized for bedside tables, and I often recommend it for creating a peaceful sleep environment with calming essential oils.
For different room sizes, here’s where I’ve found the Brevi works best:
- Small bedrooms (100-150 sq ft): Place it on a nightstand about 3-4 feet from your bed
- Home offices (150-200 sq ft): Perfect for desk placement to help with concentration and focus
- Medium living areas (200-270 sq ft): Position on a side table or shelf at roughly chest height
The compact design means it won’t take up much space, but the coverage area ensures you’ll still get the full aromatic benefits. I’ve placed mine in various spots, and it consistently delivers whether it’s tucked into a cozy corner or sitting prominently on a main surface.
Choosing the Right Diffuser Based on Dimensions
When I’m helping someone choose between different diffuser sizes, I always start with their space and usage patterns. The Brevi’s dimensions make it particularly suitable for personal spaces rather than large, open-concept areas. Selecting the right diffuser size really comes down to matching the device’s capabilities with your specific needs.
The Brevi diffuser specifications show it’s designed for efficiency rather than maximum coverage. If you’re looking for something to scent a large living room or open kitchen, you might want to consider a larger model. But for bedrooms, offices, or any space where you want focused aromatherapy benefits, the Brevi’s size is actually perfect.
I particularly appreciate how the compact design doesn’t compromise on features. You still get the full range of essential oil compatibility—whether you’re diffusing eucalyptus for respiratory support or using oils for lymphatic system support.
Conclusion – Find Your Perfect Fit
The Brevi essential oil diffuser dimensions make it a versatile choice for most personal spaces. At 4.9 inches in diameter and 3.15 inches tall, it offers the perfect balance of compact design and effective performance. The 270 square foot coverage area, combined with up to 10 hours of runtime, means you’re getting serious aromatherapy benefits without the bulk.
Whether you’re placing it on a small nightstand, desk, or side table, the Brevi’s size ensures it enhances rather than overwhelms your space. The key is understanding that this ultrasonic diffuser excels in personal and medium-sized rooms where you want consistent, quality misting without the footprint of larger models.
