Lets look at a few of these in more detail.


Standard Wall Mounted Bathroom Mirror Sizes

When shopping for a mirror to mount above your vanity, the rule of thumb is 2 to 4 inches narrower than your vanity. For example, a 24-inch wide vanity would normally get a mirror that was 20 to 24 inches wide. Not only does this look right plain, it leaves room to frame your mirror and give it extra style!

The wider your vanity is , the larger mirror you can get. Check the vanity for maximum dimensions, and choose a mirror that fits inside those dimensions.


Shower Wall Mirror Sizes

Shower wall mirrors have a special standard size. They are made to be mounted on a 45-degree angle, which actually takes up less space compared to a flat mirror that is mounted vertical or horizontal to the surface it’s on

These mirrors are often convex shaped to make up for the fact that they usually don’t have any backing behind them. The size of these mirrors is also smaller than standard wall mirrors to make up for the curve and give you a more accurate reflection.


Wall Mirrors Sizes

Wall mirrors vary the most in size. The size mirror you want depends greatly on the space available on the wall where you’re placing it.

The standard size for a typical wall mirror is 24 inches by 36 inches. However, you have to be careful when shopping for these. If you are buying a framed mirror, many manufacturers make a mirror that is the same size, but flipped horizontally so that the frame is on top instead of at the bottom and vice versa.



There is quite a range in standard mirror sizes, so try to find a mirror that fits within the range of the standard sizes for the type of mirror you’re going to get!
