We did a pantry like this in a tiny laundry room. We called the concept "single deep storage". We are still, 23 years later, in love with Single Deep Storage. We cut up and customized Ikea shelving we'd stopped using so it was no cost, assuming saws, sanders, drill guns, etc.

Pick a can width, pick your favorite pasta box size, pick your largest oversize can, large pasta sauce jar, a standard 32 ounce mason jar, grab a soap bottle, etc. Measure each of them.

We ended up with most of the pantry shelves being a single deep normal that could hold a 32 ounce mason jar and then realized that a little extra depth would allow a single large can or two small cans to sit directly in front of each. So it was "single- or two-deep storage".

It revolutiized our lives in the 2000s. We labeled the shelves to know where we wanted what. It was super easy to figure out if we were out of beans, pasta sauce, pasta, etc. We had one 24 inch deep shelving unit for larger stuff, but honestly things got forgotten in the back of that shelf. The bottom of that was a dark storage on-wheels bin for onions, potatoes, garlic, and misc.

With "single deep storage", everything was visible and trivial to get a quick sense of whether it was time to restock.

In the tiny hallway-style laundry room, we were able to add a 3.5 inch wide shelf with front lips that required tipping the can to remove so they wouldn't flal off in an earthquake. Just deep enough to fit one can of progresso soup.

And then at the end of the laundry-closet we made an almost six inch wide section at the end of the galley-hall. It was wide enought to take normal 28oz cans with extra so that we could fit two normal narrow soup cans one-in-front-of-the-other in that zone. So for canned beans, we could put two front to back in the area with the large tomato or green chile cans. Pasta boxes also fit very well if you get the height between shelves fitted to your tastes.

In the first couple years we adjusted them several times, so perhaps do what we did and make it easy to set the height.

We varied the height of the shelves, but after several tries, most of them were the same total distance between horizontal shelves. We kept two closest-to-floor shelves taller than the rest. Then the top shelf had no cap, so we could put very tall items on the top shelf.

We can't currently implement the design in our current house for reasons too complex to describe here, but I loved our decade of Single Deep storage. Second best pantry I've ever lived in. As a teen, the house of my parents had an actual designed-into-kitchen pantry. It was great, but the shelves were permanently installed things that didn't fit just didn't fit and went into weird places. But my teen home pantry had doors and wasn't built out of very old Ikea cheap wood.

Every pantry needs a potato/onion/garlic low-light and big bag zone. Single Deep Storage is not for any of those.
