I have 24 inch wide, went with 7” on the handle part with 2 inches on the supports. This size fits my hand with wiggle room and worked with smaller drawers as small as 11 inches wide. As others have said was an eye of the beholder deal.

I did custom hand made iron pulls on my Kitchen last year. Looked at store bought double and single pulls and just didn’t like anything we saw. So we chose a single, At 12” long. My drawers ranged from 20” up to 36” .

So I think its all about what looks good to you. No real rule to follow.
