I like having only one pull per drawer, no matter how wide the drawer. That way you can open the drawer with one hand without placing stress on the drawer. It's important to have smoothly-operating glides if you go this route, though. I also placed the pulls on my deep drawers at the top of the drawer fronts (not centered top to bottom), to make them easier to reach. I used a 5" pull on drawers 30" and wider, a 4" pull on drawers narrower than that (exception was my 15" pullout pantry, where I used a 5" pull).

okay... this makes sense. the drawer arrangement is sort of busy and the idea of interior dividers is a good one. In the last house our drawers were 24" wide and I found it difficult to keep thing organized especially the smaller items like measuring cups, ramekins, tupperware lids, things like that. i think with the bank of two drawers I'd be likely to go back to inset which i really do love more than full overlay. thanks for your feedback. always so appreciated by me!

I would do one pull on the 24" drawers. 30" and wider you could do 2. As gw said, nothing on the sink drawer. I'd pass on the handles used as towel bars simply because that's not a convenient place for towels. Also, I'd find it a nuisance to have them between me and sink.

I researched this recently. It seems most people think below 30", use one pull. Above 30", use two or one extra wide one. The downside of two vs. one extra wide is that you need two hands to open a drawer with two pulls, and usually one hand is already occupied whatever you are intending to put in the drawer. All my drawers are 30", which put me right on the cusp, and nobody seemed to talk about how to decide in that case. I read some guy on a woodworking forum saying modern drawer slides are so good that mechanically, you don't actually need two pulls or an extra wide pull on a 30" drawer - it's just that people tend to prefer that aesthetically. So I did some experiments pulling my 30" drawers open with one finger in the center or pulling on a centered piece of tape, and he was absolutely right. They roll beautifully. (I have Blum hardware, for reference.) As it happened, I found knobs I like, but not pulls, so I am just doing the same one knob on everything - doors and drawers.
