It will look fine. I actually have 4 different size pulls in my kitchen. My pulls are longer than yours and I used a rule of 1/2 instead of 1/3. But just so you can see different sizes together, here is a portion of my kitchen that has 13”, 19” and 10” pulls.

I always prefer pulls to be in proportion the cabinet but IMO there is no rule as to the size I do not like 2 pulls on a wide drawer also pulls are a but more contemporay when used on all cabinets so a picture of you space would be good this is what I find a good solution sometimes so that pulls are not interfering with cabinet door function. and I knd of like the look of some horizontal and some vertical. I use painters tape to both get a feel for the look and also to figure out the right proprtion for the space.

Badgergirl, I love your cabinet/drawer pulls and the way you used them. Would you mind please sharing the name of them?

Jodi Jane, my cabinet pulls are Hickory Hardware's Greenwich Pulls. The come in several different finishes and quite a few different lengths. check Hickory Hardware's website to see all the sizes. Not all online places carry all of the sizes. I bought pulls from a local independent cabinet and door hardware store. Their prices were comparable to online sites. Some big box stores also carry this line of pulls. Speaking of prices, I thought the pulls were reasonably priced. My kitchen was redone 8 years ago. The hardware looks the same as it did on install.

Thanks so much Badgergirl, I will search for the Hickory Hardware Greenwich pulls, they look lovely. It’s a real challenge to find pulls that I like in the longer lengths that aren’t appliance sized pulls (that tend to extend much farther out). I found Jeffrey Alexander, Belcastel pulls that look wonderful, but once you get to the 12” size, I’m afraid the projection is too much). I will have quite a few 36” drawers to deal with in my new kitchen.
So thank you for sharing!

Ephma I love your kitchen! Are your counters marble? I’m choosing a white for my cabinets and wondering which white you chose?

Thanks! My cabinets are BM White Dove and my counters are Opus White quartzite.

Ephma thanks so much for your quick response! It has been a few years since your post about your kitchen after all. How have your beautiful counters worked for you? They look like marble! I have slabs of Calacatta quartzite reserved. I’ve heard it’s Macaubus just cut differently-not linear. Thinking of Sea Pearl for my cabinets and White Dove for walls. Sea Pearl is on the same color card as White Dove.

The counters have been great. Opus White is bulletproof.

Ephma that’s good to hear. I’ll be thrilled if mine are as beautiful installed! And bulletproof.

I have 4 different size pulls in my kitchen also. Just replaced the hardware last week, and I actually only thought I had 2 sizes until I tried installing! I didn’t even realize it, so apparently not a visual issue to have different sized pulls!!
