I am trying to place an order for cabinet and cabinet drawer pulls - truss style pulls in stainless steel.

27 cabinet doors - I think 6" with 3 3/4 cc will do.

drawers range in width from 12" (2), 18" (2), 24" (5), 30" (5), 33" (1), 36" (2)

There are also (3) range / stove top blanks which I am thinking no handles at all

I am wondering if there is a standard or norm for width of handle relative to the width of the drawer?

I tentatively was thinking 6" pulls for all cabinets and 12" drawers. !2 inch pulls for the 18" and 24" drawers and then 18" pulls for the 30+ inch drawers.

I'd appreciate any comment or advice anyone might suggest.
