Thank you so much! I appreciate your help..

IMO a 6"' pull on a 30" drawer is not big enough but I usually use painters tape to check out what looks right I actually like pulls to be in scale to the cabinets so I never do all one size but I aslo do all one style so all pulls . Use the painters tape is is very helpful to visualize

Why only one size of pull? On a 30” drawer, a single 6” pull may look odd, I think, especially in a traditionally styled kitchen. Traditionally larger drawers had two pulls or large single pulls because you needed two hands to open a wide, heavy drawer sliding on wood runners. That need isn’t there with modern drawer slides, but if you are sticking to a traditional “look” . . .

Still, it’s all subjective so we can do whatever we like. I went weird with my drawer pulls.

Thank you Patricia, I’ll do that tomorrow with the tape. Do you think I could use the 8” pull on the trash and 21” drawers? Or would thar look too big on those yet undersized on the 30s ? With the knobs on the uppers and lower doors and already a smaller size pull on the 12” tray, I was trying to keep it from looking too busy with so many different sizes and also it make ordering and install easier and less confusing

For install you need to be on hand if the contractor is the installer use the tape . This is the look Ilike but I ma a contemporary style girl but you get the idea of scaled pulls I have never found it busy but very functional and of course all pulls not a mix of knobs and pulls . If you notice some are even vertical and some horizontal Can you post a pic of your kitchen that could help too.
