Cambro brand containers. Restaurant quality, all sizes. Google at Amazon. The best.

Do you prefer plastic or glass?

I can't do glass due to the weight and risk of breaking. Mine are all in cupboards or drawers. Dropped plastic canisters are sometimes ruined, but intact. I started with KlickKlacks, which have pressure seals. They were great, and got even better, but they don't age well. Then, I liked the OXO with the button, but the tops don't remain tight. I still have some of each in use, of course, but I changed to Rubbermaid brilliance. The shapes aren't quite as space efficient, but the large top lips make them work really well, and they stack well when empty. The tops are clear, making it easy to see what's in them from above. They're extraordinarily clear (the “brilliance” art), which elevates utilitarian to beautiful. The lids have gaskets and latches, and are very thin compared to pressure lids, and don't loosen. The latches are easy to use.

There are only a few lid sizes, which makes them interchangeable, whereas the vessels come in a number of different heights. There are large top shallow ones, which I've found very useful for seeds, powders and grains. That surprised me because I'm used to tall jars for those. The big opening makes it easy to get a large scoop in, etc. Turns out to work great, though if they're in a lower shelf, where one can't see from the side, it does mean picking them up from the stack to get the right one. But then, with the tight latched seals, They also fit nicely in small spaces, standing on end.. I cut and tape labels and info from the food bags, or use P-touch labels. Those are easier to see with backgrounnd colors, esp. with dark contents, but it doesn't bother me enough to change from clear.

Good luck with the shopping!

I got these from Walmart. They hold a five pound bag.

I bought different sizes of these for everything else, rice, beans, pasta, cookies, candy, etc. I like the better than the Oxo,

I use Sistema, the Bake It. It's made in New Zealand but readily available here. I got mine at Marshall's several years ago.

I use the Rubbermaid Brilliance containers also, and I think they are great.

I have Rubbermaid Lock-its, the size to hold a 5 pound bag of flour. They have worked great for years. Sugar, AP flour, bread flour, wheat flour. I also use canning jars for some of my smaller quantity things. I would say using the two... I prefer the plastic containers for the stuff I tend to use a one cup measure on a lot. I can also feel safe storing those on the top shelf. Wide mouth jars aren't quite wide enough for my cup, lol. But I like storing in glass. Glass jars I have on a lower shelf.

I also have some of the plastic containers that have an inside seal with a turn or flip lock in the middle of the lid rather than the outside seal and latches like the Lock-its have. Don't use those kind for your baking stuff. I like them a lot for big stuff like pasta, but the small particles of the sugar or flour can get up behind those inner seals easier IMO. I find it easier to really clean and fully trust the dry on a Lock-its than the canisters I use to store pasta.

So, I would recommend... Look for a container that holds a whole full bag of flour, and empty your flour into the container. Look for a container that has an opening plenty wide enough for your one cup measure. Make sure your lid is easy to clean, and does not have hidden or internal crevices where flour or sugar could accumulate- or could remain damp after washing without you realizing it.

I still keep mine in Tupperware in the pantry. Flour’s in the fridge in a large, round Tupperware container.

DH says he can taste the plastic of the container in the dry goods. I worked in a hotel where the kitchen gave me the big glass jars that dressings et cetera came in, like big pickle jars. They work great but I need both hands to open it. We also use various sizes of apothecary-type jars, with a plastic gasket. And like the old Planters Peanuts jars. They come in just-right sizes for many of our dry goods.

I've always used really large vintage tins that can hold all my flours in their separate bags. I like to keep a few silica gel packs inside too.

I've switched to OXO hard plastic to keep out the ants... which can even chew some softer/older plastics.

Carol, you remind me: My mother had giant popcorn tins (likely actually steel) from the 1960’s, painted to match her kitchen. They had tops of the same material, that fit very tightly. No ants. You had to use the wrong end of a spoon to pry them open, and bang them closed with the heel of your hand. Easy to get measuring cups and whole arms into.

Before I switched to glass, I had these. They worked very well for years, easy to open and access and they fit well on my cabinet shelf. I think the bad reviews are for the larger 50 cup size. Mine were definitely air-tight.

Food Storage Containers

I use Rubbermaid brilliance for general food storage. I have plastic, but bought glass for my new house. Lids are the same plastic for both. At least one ”professional” review out there dings them for supposedly being succeptible to mold if above the seal stays wet, but that’s not something I’ve experienced in my couple years of using them.

For flour, I have some Prokeeper canisters. At 16 cups, they’re about the size you’re asking for. King Arthur sells them, among other, but I got mine at Target.

I store a number of dry goods in wide mouth canning jars with plastic lids you can buy separately. I like peanut butter jars too, since they tend to have a bit wider openings.

I just ordered Marmir storages containers for rice and glor etc from Amazon, they come with labels and are sealed containers.

Glor : flour sorry using phone far from pc so no edit available

I have the same Prokeeper container foodonastump has, also got it at Target. I keep my flours in them. I also have a smaller size for whole wheat flour, since I don't use much of that and only buy a small bag at a time. What I really like about the Prokeeper is it has a magnetically attached leveler housed on the inside lid; not a necessity but something nice to have right there when you need it.

For my grains, I use glass containers, the Bormioli Rocco Fido ones made in Italy. I've gotten all of mine at HomeGoods, but you can order on-line too. Very thick, high quality glass with rubber gaskets (which you can buy separately should you need replacements).
