My pantry is roughly 8 X 3. I have 8" deep shelves on one long wall, 18" deep shelves on one short wall and a section on the other short wall to house ironing board, mop, vaccum and cleaning products that is 12" deep. The 18" deep wall has a section for vertical storage for cookie sheets and lasagne pans etc. And a very high section for a large stockpot that only gets ocassional use. The long wall of 8" deep shelving has all adjustable shelves. I recommend this to you so that you can then adjust as needed once you start filling the pantry. After that, I doubt you'll ever move the adjustable shelves again (I haven't had to in two years). But flexibility is wonderful in a pantry so I recommend it.

Buehl has great diagrams of her pantry...I think the thread is titled "Sharb-Inspired Pantry".

Good luck! Someone (is it you?) has an awesome screen door for a pantry...red and old fashioned. I love it!

I decided my shelf heights ahead of time (different heights for different things...Worth the time to think it through), because I knew that I'd never adjust them after they were in and wanted the more sturdy, stable construction of stationary shelves. They are white melamine with wood edges...Look neat and bright, and are easy to wipe clean.

I have 16" deep shelves on the back and 12" deep on one side. With your setup, I'd probably do shelves on each side...without corners, which are the least efficient storage.

From the floor, my shelf spacing is

19" for wheeled bins that hold wheat, beans, and pet food

2 @ 14-15" for small appliances, special grain storage, and larger items, like baskets of fruit and potatoes

2 @ 10" for dbl tall stacks of canned foods

1 more at 14" for cereal boxes, less often used small appliances, etc.,

and the top shelf is about 21" from the ceiling for paper towels, baskets, etc.

There is a pantry thread with links to other pantry threads in the gallery section of the forum...Lots of good info and great photos.

I haven't used mine, but I have 18" deep shelves, 24" deep (both for platters, etc.). Then, I have some 6" deep and some 12". In my current house, I HAVE adjusted my pantry shelves. I think I got some of both in this house. I figure, why not have flexibility? My pantry is long and narrow and doesn't have a screen door--that part would scare me--having to keep it neat!
