What Size LED Mirror Do You Need? Size Guide by Basin & Wall
AURA Mirrors Co.Contents
The width of your LED mirror should sit close to the width of your basin or vanity unit, ideally between 70 and 90 percent of it, and its centre should sit at roughly average eye level, around 150 to 160cm from the floor. Everything else, from cloakroom mirrors to statement pieces, follows from those two rules.
At a glance
- Aim for a mirror width between 70 and 90 percent of your vanity's width, and never wider than the unit itself.
- For a pedestal basin, match the mirror width to the basin width, or go slightly narrower.
- Mount the mirror's centre at roughly average eye level, around 150 to 160cm from the floor.
- Leave 10 to 20cm of clearance above the tap and below the ceiling where possible.
- In small bathrooms, don't undersize the mirror purely because the room is compact.
Mirror sizing is one of those decisions that's easy to get roughly right and just as easy to get subtly wrong. A mirror that's too wide for the vanity below it looks top-heavy; one that's too narrow looks like an afterthought. This guide sets out the rules designers actually use, then maps them onto AURA's own size ranges so you can go straight from "my basin is this wide" to "this is the mirror I need."
The basic width rule
For a mirror above a single vanity unit, aim for a width between 70 and 90 percent of the vanity's own width, and avoid going wider than the unit itself. In practice, that means a couple of centimetres of visible wall or tile should show on either side of the mirror once it's mounted, rather than the mirror running edge to edge with the cabinet below.
For a pedestal basin with no vanity either side, let the basin itself be your guide instead. A mirror the same width as the basin, or slightly narrower, reads as balanced; anything noticeably wider tends to overwhelm the fixture below it.
Height and mounting position
Most bathroom mirrors are mounted so their centre sits at roughly average eye level, commonly cited as between about 150 and 165cm from the floor. As a secondary check, aim to leave a gap of around 10 to 20cm between the bottom of the mirror and the top of the tap or basin, and a similar or slightly larger gap between the top of the mirror and the ceiling, so the mirror doesn't feel cramped into the space.
In a household where several people of noticeably different heights share the same bathroom, a taller mirror, or one mounted a little lower than the strict "average eye level" rule, tends to work better in practice than mounting purely to a single average.
Matching AURA's sizes to your basin
AURA's rectangular GLOW comes in three sizes: 45 x 60cm, 50 x 70cm and 80 x 60cm. The round HALO comes in 50cm, 60cm and 80cm diameters. Mapped against typical basin widths:
| Basin or vanity width | Suggested GLOW size | Suggested HALO diameter |
|---|---|---|
| Cloakroom / narrow basin (up to ~55cm) | 45 x 60cm | 50cm |
| Standard single vanity (~60-70cm) | 50 x 70cm | 60cm |
| Wide vanity / double basin (80cm+) | 80 x 60cm (landscape) | 80cm |
These are starting points rather than fixed rules. If your basin sits between two sizes, or your wall is unusually narrow or wide for the fixture below it, it's worth measuring the actual wall space available before ordering, since the wall, not just the basin, sets the outer limit on what will look right.
Small bathrooms and cloakrooms
In a genuinely small space, resist the instinct to go smaller across the board. A mirror that's too small on a compact wall can make the room feel more cramped, not less, because it draws attention to how little wall space there is. A mirror close to the full width of a narrow basin, rather than a noticeably smaller one, tends to make a small bathroom feel more considered.

Frequently Asked Questions
Should a bathroom mirror be wider than the basin?
Generally no. For a pedestal basin, match the mirror width to the basin or go slightly narrower. For a vanity unit, keep the mirror within 70 to 90 percent of the vanity's own width rather than exceeding it.
How high should a bathroom mirror be mounted?
Most mirrors are mounted with their centre at roughly average eye level, commonly around 150 to 160cm from the floor, with some allowance made if the bathroom is shared by people of noticeably different heights.
What size mirror suits a small bathroom or cloakroom?
A mirror close to the full width of the basin, rather than a deliberately undersized one, tends to suit small bathrooms better, since an overly small mirror can make a compact wall look emptier rather than larger.
Do I need to leave a gap between the mirror and the ceiling?
It's not a strict requirement, but leaving a similar gap above the mirror to the gap you leave below it, roughly 10 to 20cm, generally looks more considered than mounting the mirror hard against the ceiling line.
