I have a small galley kitchen and am looking to get European (modern) door pulls (as in the photo below). I have espresso slab cabinets. One side of the kitchen (with appliances) has several 15" wide uppers (42" length). The other side has six 15" x 42" cabinets on top. On the bottom are three 3-drawer stacks, each 30" wide (two big drawers topped with a third small drawer). My contractor suggested pulls 6–9" for the drawers (every drawer the same size pull) and 3–4" for all the cabinets (every cabinet the same size pull). Opinions? And should there be a specific ratio? For instance, should the larger handles be twice as big as the small? One-third larger? Two inches larger? Please help.

Also, can anyone suggest top-quality ones that aren't majorly expensive?

Thank you!
