Here's how it looks in our kitchen: pulls in the corners.

It's all personal preference with the style of door that you have.

A suggestion is to scotch tape the hardware where you'd like the permanent install to see how it feels and appeals to you. The tape won't harm the doors. Try it for a few days. You can even put one on a few doors in different places to see what floats your boat. This is a good idea to use when you are trying out a few different styles and finishes too. That's what I did. I ended up going with the hardware more toward the bottom corner.

I dislike the hardware in the middle of the door. It just looks plain wrong to me, IMO.

I've seen them in both locations and I decided to do mine in the lower corner (but not too low - actually about 3" up from the bottom) because (a) I am only 5"1" so it would be pushing it for me to reach it in the center of the stile of the door, and (b) I am a fan of symmetry and was worried that then I would need to put the lower cab knobs in a similar location, which would be really low for a taller person. I never thought of it as a problem of being "dated" though - more of a practicality thing.

My doors in my 1983 cabinets were put in the middle by the builder and I always hated them there. I never used them and the cabinets showed a lot of wear where I used my hands to open them.

I put the handle on my new doors in the lower corners and it looks much better and works better, too.

My friend has hers in the center of the doors and it is about 27 years old. I definately think it dates it. I also think it is easier to open on the lower corners than reaching to the center. Just my two cents.

Thanks for all of your responses. I think the placement of the pull is also dictated by its size. If one is using a 4-6" long pull, it might look out-of-place tucked into the lower corner vs up-and-in a few inches towards the center of the panel.

In my BIL's cabinet shop, here's what they typically do:

lower cabs: drill for knob or upper end of handle where bottom edge of top rail meets center of stile

upper cabs: drill for knob or lower end of handle where top edge of bottom rail meets center of stile

I know pretty much everyone here is TKO so a definition may be superfluous, but the rail is the horizontal board at top, bottom and sometimes middle of the door; the stile is the vertical.
