Minimum Depth of a Seating Counter

Eighteen inches is comfortable for sitting and eating from plates. February 11, 2010

I have a split level counter to do at an island. There will be seating on one side (42" to top of counter), cabinets on the other (36" tall counter). There will be a 40 1/2" tall half wall between the two areas. How deep should the upper counter be? I was thinking of a 12" overhang plus 4 1/2" for the wall plus 1 1/2" overhang on the other side, but 18" seems very deep for this.

From contributor J:
16" minimum to eat with a plate and have a glass set 45 degrees to center, 18 is comfortable, 12 is a place to set a purse.

From the original questioner:
Is the 12" overhang enough to pull a chair under?

From contributor J:
Good bar ergonomics call for 9-11" of overhang to sit at.

I concur with contributor J.
