Looking for some suggestions for our pantry wall hardware.

The drawing below is a rough cabinet layout from our cabinet maker.

The two outside doors on the left and the two outside doors on the right measure 60 inches in height.

The two center doors measure 53 inches in height.

I am planning on using pulls for all of the doors. Knobs will be placed on the upper cabinets and the opening in the center is for a TV.

What size pulls would you suggest for the doors?

The line of hardware I am looking at has 6 & 8 inch pulls - as well as 12 & 18 inch appliance pulls - available.

Should all of the pulls be the same size or should they bump down a size for the center doors?

The kitchen prep area and island will have a combination of cup pulls and knobs. The dishwasher and beverage fridge will have 12'' pulls and the french door fridge will have 18'' pulls. All of the hardware will be antique english on BM Silver Satin cabinets.

I like symmetry and can't quite visualize what would look best in this run of cabinets.

Thanks in advance for any and all input!
