A:Answer The mirror size is about one and a 1/2 compact (powder) makeups in circumference. I can't find my paperwork to give exact dimensions, sorry. It is larger than a regular compact, but not too large. It is actually a perfect size for looking at parts of your face close up. If you are looking for a mirror that gives you a full view of entire face, this is not the mirror. I use it to be able to see the eyebrows that need to be plucked and yes, the chinny, chin, chin hairs!
