How the Five Compare on the Numbers
Every listing in this pool publishes a capacity and almost none publishes it in the same unit. Liters, fluid ounces, cups and quarts all appear, sometimes two at once, and one listing publishes a figure in its title that is not a volume at all. Comparing these five means converting before you can even start.
Rubbermaid publishes 18 Cup in its size field and 32 oz in its title. Shazo publishes 6.3 L and 213 oz on one set and 11 L and 372 fl oz on another. OXO publishes 3.4 qt and 3.2 L for each of three dispensers. Snapware publishes 22.8 cup each. One listing elsewhere in this pool publishes liters, fluid ounces and quarts for the same container.
What the table cannot do is put these five on one scale. A cup is a volume, a quart is a volume, a liter is a volume, and a 32-ounce box of cereal is a weight. Four of the five publish a volume in some unit. The fifth publishes the size of the box it swallows, which is a useful thing to know and not a capacity.
One Listing Publishes Two Different Kinds of Figure
Eighteen Cups, or a Thirty Two Ounce Box
The Rubbermaid single container publishes 18 Cup in its size field. Its title publishes 32oz Capacity, and its own bullet explains what that means: fits an entire 32-ounce box of cereal. Those two figures are not in conflict, because 18 cups is the volume and 32 ounces is the weight of the cereal box that fits inside it.
The trouble is that a buyer scanning titles sees 32 oz beside another listing’s 213 oz and reads them as the same kind of number. They are not. 18 cups is far more than 32 fluid ounces, so on volume this container sits between the Snapware pair and the smaller Shazo. Its dimension fields read 4.75 by 10.25 by 9.38 inches and it publishes no weight.
Three Units for One Container
One listing elsewhere in this pool goes the other way and publishes everything. Its containers are stated in liters, in fluid ounces and in quarts, which is the same volume written three ways so that nobody has to convert anything. It is the only listing on this fact sheet that does that, and the clearest capacity statement among the sixteen. None of these five manages it.
The rest publish one unit or two. Shazo publishes liters first and ounces second on both of its sets. OXO publishes quarts first and liters second. Snapware publishes cups and nothing else. Rubbermaid publishes cups in a field and an ounce figure in a title. Five listings, four conventions.
Where the Volume and the Box Disagree
Eleven Liters in Two Different Boxes
The extra large Shazo set publishes 11 L, or 372 fl oz, for each of two containers, and its own bullet gives the size as 11.2 inches long by 5.2 wide by 9.8 high. Its dimension fields read 7.1 by 13.2 by 10.2 inches instead. Those are two different boxes, and the one in the sentence is smaller than the one in the fields.
This page uses the sentence, because the maker wrote it out alongside the capacity. What it cannot resolve is which box holds 11 liters. The smaller Shazo set does not have the problem: it publishes 10.8 by 5.1 by 11.2 inches in its bullet and 5.1 by 10.8 by 11.2 in its fields, which is the same three figures reordered.
Two Listings Publish No Size at All
OXO and Snapware publish a capacity and nothing you could measure against a shelf. OXO publishes three 3.4 qt dispensers, states they are contoured for easy dispensing even when full and shaped for space-efficient storage, and gives no dimension. Snapware publishes two 22.8-cup containers, states they hold a full box of cereal, and gives no dimension either.
That is the gap a capacity figure cannot fill. A 3.4 quart dispenser and a 22.8 cup container are both roughly a box of cereal, and neither listing says whether it will stand up under a kitchen shelf. OXO publishes 5.0 pounds for three and Snapware 2.25 pounds for two, which is the only clue either gives about bulk.
What the Lids and the Washing Add
Four Lids, Four Mechanisms
Every pick here publishes a lid and the mechanisms differ more than the capacities. Both Shazo sets publish a four-sided snap locking lid with a silicone seal, and the extra large one adds a removable seal and an easy-grip carry handle. OXO publishes a lid that pops open and seals shut with one hand. Rubbermaid and Snapware both publish a flip-top.
Only one of the five publishes a flap in the lid for getting food out without opening it: the smaller Shazo set states an extra secure flap for easy access. HKJ Chef, elsewhere in the pool, publishes a flip-top plus two separate pour spouts for the same reason. A flip-top is what turns a canister into a dispenser.
The Washing Rules Split Three Ways
Snapware publishes the widest permission here: the top rack of a dishwasher, the freezer and the microwave. Rubbermaid publishes dishwasher safe on Tritan plastic that also resists odors and stains. The smaller Shazo set publishes a dishwasher-safe clear design. OXO publishes the only conditional rule of the five.
The OXO instruction is worth quoting because it is the only split one: the silicone gasket is dishwasher safe, hand wash other parts. That is a maker telling you the seal and the body need different treatment on a container sold as a three piece set. The extra large Shazo set publishes no dishwasher, hand wash or rinse instruction anywhere.
Which One Fits Your Kitchen
You want one container for one cereal box. The Rubbermaid single publishes 18 Cup in its size field and a bullet saying it fits an entire 32-ounce box, in shatterproof Tritan plastic with a contoured body for one-handed pouring, and dimension fields of 4.75 by 10.25 by 9.38 inches.
You buy rice and flour in sacks. The extra large Shazo set publishes 11 L, or 372 fl oz, for each of two containers, with a four-sided snap lock, a removable silicone seal, an easy-grip carry handle on each lid and two measuring cups.
You want the capacity and the size to agree. The smaller Shazo set publishes 6.3 L or 213 oz per container and 10.8 by 5.1 by 11.2 inches in its own bullet, which its dimension fields repeat in a different order and no other pick here manages at all.
You want three matching dispensers. OXO publishes three 3.4 qt containers, lids that pop open and seal with one hand, contoured bodies for pouring when full, and the only split washing rule here: gasket in the dishwasher, everything else by hand.
You want the widest permissions. Snapware publishes two 22.8-cup containers with flip-top snap-lock lids, stated safe in the top rack of a dishwasher, the freezer and the microwave, and made in the USA, at 2.25 pounds for the pair.
What We Could Not Verify
Every figure above is a manufacturer’s own published number or sentence. These are the things we went looking for across all sixteen listings and did not find.
- A dimension of any kind from OXO or Snapware, so whether either fits a shelf is unstated.
- Which of the two boxes holds 11 liters on the extra large Shazo set, whose bullet and dimension fields disagree.
- A weight from the Rubbermaid single container.
- A dishwasher, hand wash or rinse instruction from the extra large Shazo set.
- Any of these five publishing a capacity in the same unit as all the others, which only one listing elsewhere in the pool does.
- A lid or gasket replacement statement from any of the five, on containers whose seal is the part that fails.
