How to mark mirror center point?

How would you recommend that I (a) determine the precise center of the mirror and (b) what should I use to mark it?

I normally take the mirror out, trace around the mirror on a piece of paper. Then cut out the trace. Fold the circle in half and then in half again. Cut the little corner off. Unfold the paper, lay it over your mirror and where the hole is mark your center point with either a sharpie or a donut sticker.

You can use the little donut reinforcement stickers for binder paper. Or, you can buy inexpensive templates and stickers from Catseye or Farpoint.

The traced circle method can work well, but there is a bit of wiggle room in placing circle back on the mirror and placing the Sharpie dot. Check your work by measuring the location at right angles with a ruler or tape measure, taking care with the mirror surface. It’s quick and you may end up redoing your center dot. Placing a white paper ring with a tweezers after the center is determined helps visibility of the center.

When placing the paper on the mirror, through which you make the Sharpie dot, I scotch tape the paper to the edge of the mirror to guarantee it stays centered and doesn't move.
After the dot is placed, the paper and tape are removed and I apply a paper reinforcement ring with tweezers to guarantee I place the dot on the mirror precisely at the center of the ring.
