Primary bath reno has two vanities in different sizes. On the wall directly across from entrance there is one 5' vanity with a single sink to left side with 2 single sconces on either side and one double sconce in center. To the right of the entrance there is one 6' vanity with a single sink on right side with 2 single sconces on each side and a triple sconce in center.

What size mirrors should be used? 20 inch for the 5' vanity and 24 inch for 6' vanity? or should they all be the same size??
