We're nearing the end of a kitchen remodel and have opened our kitchen to a living/eating room. The counter will go through to the other side. The plan is to put wood panels under the counter and along the whole wall. The passthrough is not centered on the wall. There's also a corner cabinet that opens from the other side at one end. So the 'panel' at the far right will be vertical (it's the cabinet door).

The question is how wide do we make the other panels? The original thought was put a narrow (vertical panel) at the other end and then 3 wider (horizontal) panels in the middle (but because the passthrough isn't centered, it won't fall evenly with regards to the counter/pass through). Or we could make all the panels (except the cabinet door one) even, which makes them nearly square. Or we can make more of them, which makes them more similar to the one that's the cabinet door (and in this case it makes vertical rectangles).

The picture only helps some (unfortunately the appliances are in the way of taking a shot of the whole wall).
