Because they're so small, I'd go knobs.
As a matter of fact, I am going knobs!

I went with cup pulls for two reasons:

(1) I used pulls on all the other drawers in my design
(2) My spice drawers do not have the soft-close feature that my larger drawers do and I found it sturdier to open/close the drawer with a pull. I have a small kitchen and use these drawers everyday because they store cooking utensils next to my range, so I wanted them to be easy to manage.

Thanks for the good points! Brooklyngalley, are your drawers 5" as well? I hope to store utensils in mine too - good idea (mine will be next to my range too)

Not sure if this will help, but I chose to only put cup pulls on the top drawers of our cabs (used pulls for the drawers lower down and knobs on the few doors we have). Although it's not a huge ergonomic issue, it's a little bit easier to grab a pull or knob than get your fingers under a cup pull on lower drawers. Can't take the credit, though....got the idea from mamagoose. :)

Thanks, hlove. Can you share a picture please?
