Choosing the right mirror size for your bathroom can make a big difference in both style and function. Whether you're designing a powder room or renovating a master bath, finding the best fit is essential.
🪞Standard Mirror Sizes for Bathrooms
A common rule of thumb is that a bathroom mirror should be 2 to 4 inches narrower than the vanity it hangs above. For example, a 24-inch vanity pairs well with a 20-inch mirror:
or a 36-inch vanity fits a 30–32 inch mirror:
Double vanities often use two mirrors, each sized to the individual sink.
For small spaces, a 24x32” wall mirror is one of the most popular sizes — it’s compact enough for most bathrooms, yet tall enough to provide a full reflection. Mirrors in this size (like our Balian Collection) work beautifully in guest baths and cozy powder rooms.
💡 Other Factors to Consider
Vertical space: Tall mirrors (32” and up) help elongate the room and reflect more light.
Lighting: Make sure your mirror doesn’t block sconces or overhead lights.
Frame style: A slim or frameless mirror feels minimal, while a carved wood frame adds warmth and detail.
🎯 Final Tip
The best mirror size for your bathroom balances proportion, functionality, and style. And don’t forget — a well-placed mirror also adds depth and brightness to the space.
