Mirror Size
The first decision to make when you’re choosing a wall mirror is how large it should be. The size of the mirror should be influenced by a couple of factors. Size does matters because the size of your mirror can influence the impact you want to create. The selection of size should also be based on whether you want the mirror to be a focal point, an accent, or merely act as the background. A single small mirror on a large wall will look lost and insignificant.
Choose a size that is appropriate for the wall you have selected. If you want your mirror to be a focal point in your room, make sure it is large enough to stand out, but also define it by choosing a frame that makes it even more noticeable. If you want your mirror to become part of the background, you should choose one that is extra large so that its function then becomes to make your space appear larger.
Don’t give it a frame that draws attention to itself. Smaller mirrors can be used as accents, catching light here, reflecting an interesting object there. They can also be used in groups. If you do plan to use smaller mirrors in groups, remember that together are acting to form a much larger shape and these could act as a focal point in the room. You need to ask yourself, where am I hanging it?
What size is the wall space? The size of the wall that you’re placing it on and how big an impact you want the mirror to make in your room. If you’re hanging the mirror on a large wall in your living room, dining room or bedroom and you want to make a bold statement, opt for an extra-large mirror, measuring between 25 and 31 inches on each side. If you’re using the mirror as an accent on a small wall near your entryway, you may need one as small as 10 inches on each side. Measure your wall so you know how much space you have to work with and determine how much of it you want the mirror to fill.
