Can this calculator work with metric measurements?

The tool requires vanity width and side margin inputs in inches only; metric conversions would need to be done manually before entering values.

What if I have an unusual vanity size not listed in the results?

The calculator accepts any vanity width input and generates proportional mirror width and height ranges based on the 0.75 to 0.95 vanity width formula, regardless of whether the size appears in the reference table.

Does the calculator consider the mirror frame thickness?

No, the recommended dimensions refer to the mirror glass size only; frame thickness would need to be added separately to the overall installation measurements.

How do I choose between single and double mirror options?

Select single mirror if you have one sink or want one mirror above the vanity; choose double mirror if you have two sinks or want two separate mirrors, each sized according to the respective vanity section.
