Choosing the right size of Bathroom Mirror is more important than most folks believe. It affects the space, the room feel and how everything looks. Whether you want to update a big bath or set up a tiny bathroom, a good mirror lights the place and eases the everyday routine.
A simple rule often helps. Do not hang a mirror wider than the vanity under it. Most Bathroom Mirror sizes come in a usual range of sizes that works for typical setups.
How to Choose the Right Bathroom Mirror Size
Practical advice is choose a mirror that is two to four inches narrower than the vanity on both sides. This way you get nice visual balance and avoid the space looking messy.
You can also think about proportions. The mirror should match two-thirds to three-quarters of the width of the furniture below. For instance, for a vanity of 60 inches wide, a Bathroom Mirror of around 40 to 45 inches works well.
Meanwhile a double vanity of 60 inches can go with a mirror of 56 to 58 inches, if it fits beetween the light fixtures and does not cover taps or tools on the vanity face.
The same rule counts for tinier vanities. A vanity of middle size, 600 mm wide, pairs well with mirrors of 500 to 600 mm wide.
The height also plays a role. Usual height for Bathroom Mirror options ranges between 30 and 36 inches. That range gives enough space for a good look.
To find the right height, measure the distance from the lights to the tap. The mirror should leave space above the tap and stay under the lights. Standard depth of the sink is 24 inches, plus a small bump from the countertop, which puts the wall around 25 inches behind the edge of the vanity.
That gap can make it hard too reach the mirror, if it is too high.
Mirrors need to be tall enough so that each user of the bathroom can see their face. Up to six feet from the floor is a good maximum, with the bottom edge low enough for shorter people.
So, whether one big mirror or two smaller ones? When the sinks stand side by side, one big mirror usually looks cleaner. Even so two separate mirrors maybe work better, depending on the setup of the lights.
Everything depends on the layout. Deciding ahead about size andposition makes buying a mirror much more simple and fast.
