As usual, Beverly nails it!!

The mirror should be either smaller or the same size as the buffet .

I gotta tell ya, I am not a fan of that huge mirror over the buffet. I think it dwarfs the buffet.

IMO mirrors in DRs are not wonderful no one I know wants to see themselves eating and often the mirror reflects nothing worth seeing twice. Get a great piece of art instead.BTW if you insist the mirror needs to be no larger than the buffet and that includes the frame.

Thank you that was my question! No larger than buffet including the frame.

You don't say what space this is for, but to me "buffet" means "dining room". I would not hang a mirror in a dining room. I would hang art. However if this is for another space (like an entry way as some of the pics above denote), then I would not hang a mirror horizontally, I would hang it with the height vertically.

In my dining room.

Absolutely vertical. I’ve had a mirror in every DR I’ve ever had, as did my mother. They are traditional over a sideboard or buffet. No one has ever spent the meal looking in the mirror. It should fleck tge room - wallpaper or pain, curtains opposite, the table with its lovely china/crystal/silver/candlesticks. It could not be more classic.

Echo - no mirrors in dining room. I don't know anyone who looks good chewing.
