How to Size a Bathroom Vanity Bar Light Over a Mirror
- 1). Measure the width of the mirror and write the measurement down.
- 2). Measure the space between the mirror and the ceiling. If it isn't a large space, you must be certain that there is room for the fixture. Most light bars require at least 6 inches between the top of the mirror and the ceiling for proper installation.
- 3). Strike a line with a pencil about 2 inches above the mirror, across the top. Strike another line, parallel and above the first, to indicate where you will place the light bar.
- 4). Measure your light bar and make sure it isn't too long for the mirror or too wide for the space between the mirror and the ceiling.
