Balanced vanity proportions
A mirror commonly looks balanced when it is slightly narrower than the vanity. The calculator uses a practical range and then limits the result to the clear wall width you enter.
Mirror Size Calculator
Use your vanity and wall measurements to estimate a balanced mirror width, suitable shapes and matching products from our LED bathroom mirror range. Measurements are planning guidance; always confirm the selected product dimensions and installation clearances.
Your recommended width, suitable shapes and matching mirror sizes will appear here.

This result is a visual proportion guide, not an electrical or installation specification. Confirm taps, cabinetry, mounting points and cable position before ordering. Hardwired work must be completed by a qualified electrician.
How the bathroom mirror size recommendation works
Single and double basins
A double vanity usually suits a wider rectangle or two coordinated mirrors, while a single vanity can work well with round, oval, arched or rectangular shapes.
