1. What is the Mirror Size Formula?

The standard formula for bathroom mirror sizing is to multiply the vanity width by 0.8. This creates a balanced, proportional look while leaving space on either side of the mirror.

2. How Does the Calculator Work?

The calculator uses the simple formula:

Where:

• \( Vanity\ Width \) — The width of your bathroom vanity in inches
• \( 0.8 \) — The standard multiplier for proportional mirror sizing

Explanation: This calculation ensures your mirror is appropriately sized for your vanity while maintaining aesthetic balance.

3. Importance of Proper Mirror Sizing

Details: Correct mirror sizing enhances bathroom aesthetics, improves functionality, and creates visual harmony with your vanity and other fixtures.

4. Using the Calculator

Tips: Measure your vanity width accurately in inches. The calculator will recommend an ideal mirror width that's 80% of your vanity width.

5. Frequently Asked Questions (FAQ)

Q1: Can I go larger than the recommended size?
A: While you can go slightly larger, maintaining the 0.8 ratio typically provides the most balanced look.

Q2: What if I have a double vanity?
A: Measure the total width of the vanity unit and apply the same formula.

Q3: Does this work for vertical mirrors?
A: This calculation is primarily for width. Mirror height is typically determined by ceiling height and user height.

Q4: What about mirrors with frames?
A: The calculation is for the mirror glass itself. Account for frame width separately when planning your installation.

Q5: Is this formula appropriate for all bathroom styles?
A: While it works for most styles, some modern or minimalist designs might call for different proportions.
