What Size Mirror Should I Buy? The Complete Mirror Size Guide
Choosing the right mirror size can completely transform a room. A mirror that's too small may look insignificant, while one that's too large can overwhelm the space.
Whether you're shopping for a bathroom mirror, hallway mirror, bedroom mirror or statement decorative mirror, selecting the correct size is essential for achieving a balanced and stylish look.
This guide will help you determine the ideal mirror size for every room in your home.
Why Mirror Size Matters
Mirrors do more than simply provide a reflection.
They can:
- Make small rooms feel larger
- Increase natural light
- Create a decorative focal point
- Add depth and visual interest
- Improve the balance of a room
The key is choosing a mirror that is proportional to the furniture and wall space around it.
Quick Mirror Size Guide
| Location | Recommended Mirror Width |
|---|---|
| Bathroom Vanity | 70–90% of vanity width |
| Above Console Table | 60–80% of table width |
| Above Fireplace | 60–80% of mantel width |
| Full-Length Mirror | Minimum 150 cm high |
| Bedroom Dresser | 60–80% of dresser width |
What Size Mirror for a Bathroom Vanity?
The most common mirror sizing question relates to bathrooms.
A good rule is:
Choose a mirror that is approximately 70–90% of the width of your vanity.
Examples
| Vanity Width | Suggested Mirror Width |
| 60 cm | 45–55 cm |
| 80 cm | 60–72 cm |
| 100 cm | 70–90 cm |
| 120 cm | 85–110 cm |
| 150 cm | 105–135 cm |
The mirror should usually be slightly narrower than the vanity to create visual balance.
What Size Round Mirror Should I Buy?
Round mirrors are incredibly popular in modern homes.
Bathroom Round Mirrors
| Vanity Width | Recommended Round Mirror |
| 60–80 cm | 50–60 cm mirror |
| 90–120 cm | 70–80 cm mirror |
| 120–150 cm | 80–100 cm mirror |
Entryway or Decorative Mirrors
For feature walls and entryways:
- Small statement mirror: 60 cm
- Medium statement mirror: 80 cm
- Large statement mirror: 100 cm
- Oversized statement mirror: 120 cm+
Larger mirrors often create a more luxurious appearance.
What Size Mirror Above a Console Table?
A mirror above a console table should generally be:
60–80% of the table width.
Example
| Console Width | Mirror Width |
| 100 cm | 60–80 cm |
| 120 cm | 72–96 cm |
| 150 cm | 90–120 cm |
Position the mirror approximately 15–25 cm above the console table.
What Size Mirror Above a Fireplace?
For a balanced look:
- Mirror width should be approximately 60–80% of the mantel width.
- Leave some wall space visible around the mirror.
- Avoid mirrors that extend beyond the fireplace width.
This creates a focal point without overpowering the room.
Choosing a Full-Length Mirror
Full-length mirrors are ideal for bedrooms, dressing rooms and entryways.
Recommended Sizes
| Mirror Height | Suitable For |
| 150 cm | Basic full-body reflection |
| 170 cm | Most popular size |
| 180 cm | Premium full-length mirror |
| 200 cm+ | Luxury oversized mirrors |
For most homes, a mirror between 170 cm and 180 cm high provides the best balance.
Mirrors for Small Rooms
One of the easiest ways to make a room feel larger is by using a larger mirror.
In small rooms:
- Choose the largest mirror the wall can comfortably accommodate.
- Position mirrors opposite windows where possible.
- Consider round mirrors to soften the room.
- Use full-length mirrors to increase the sense of height.
Large mirrors can dramatically improve the feeling of space and brightness.
Common Mirror Sizing Mistakes
Choosing a Mirror That Is Too Small
This is by far the most common mistake.
A slightly larger mirror generally looks more expensive and more intentional.
Ignoring Furniture Scale
The mirror should relate to nearby furniture such as vanities, consoles and dressers.
Hanging Too High
The centre of the mirror should generally sit close to eye level.
Not Considering Reflection
Think about what the mirror will reflect.
Positioning a mirror opposite a window can maximise natural light and enhance the room.
