We need to see your kitchen. Is it all installed ? IMO handles, knobs, backsplash and wall color are all best when chosen after cabinets, flooring and counter are in. So post pics here in a comment DO NOT start another post

Cabinets going in end of this week and they wanted hardware onsite for the install
Completely agree need to see the hardware on actual cabinetry so I ordered all sizes for the pulls except for the 12 inch . I did not realize those measurements were for the holes. Thank you !!

Handles ship pretty quick. Are the cabinets at your house already? If so - open a box and have a look . Or go to a local big box store and hold them up to their cabinets to get a sense of scale.

Cabinets are in
Island= (4) 24 inch drawers
(1) 18 inch drawer then 18 inch trash pull

set of
(3) 21 inch drawers by stove opening

Then (3) 31 inch drawers next to dishwasher opening and refrigerator

9 inch spice pullout next to stove

I have sizes of the available hardware
Below is the 5,6 and 7 inch pulls
Also ordered the 8 inch just in case

Was going to maybe use combination of 6 and 7 inch pulls or maybe 8 inch on the 31 inch drawer .
Spice pull probably knob as the smallest pull is 5 inches ?
Don’t know if making this too complicated

All cabinets upper and under sink will be knobs

Pros will usually tell you only to use 2 different sizes because otherwise it will look too busy; we did use 12” pulls on our 30” drawers, though, and it does not look busy at all. (We also used 6” on doors and smallest drawers, but most are 9”.)

That is way too complicated with the handle. The only time I do that many different sizes is if someone is doing full length bar pulls on a very modern kitchen.

Pick a size for all the doors. Then pick a size for all drawers smaller than 30" wide. You can do a wider handle ( if you want ) on the wider drawers but it should be an obvious difference - not 1" That will look like a mistake .

Then you look at any special sizes you might need : small drawers, tall pantry doors, glass doors.

Good luck!

Was only going to use 6 or 7 inch pulls on the drawers 18 to 24 inches.
Was not sure which size would be better ?
And maybe 8 on the 31 inch drawers
Not using all those sizes
All knobs on doors and super Susan

Any advice for knob placement !
He is recommending 2 inch up on door frame
I am seeing people say 2 1-2 to 3 up on door is the norm

You could use 9” pulls on all of those, if you want to keep it simple (or whatever size that co makes). I had my installer hold the knobs/pulls up to the doors/drawers so I could decide where I wanted them; much of this is down to personal preference. The installer should be able to show you different ways people do theirs so you can see the difference.

They don’t have 9 inch in that style pull only 5,6,7,8 or 12

I usually do knobs based on the size of the stiles and rails

In this picture, the hole is across from where the 2 meet. If it is a diagonal joint then I suggest a little higher so you are not drilling to close to the joint.

Thank you Deb ! 2 inch stiles and rails and contractor wants to have them even where the stile and rail meet like you show . Joints are vertical not diagonal
