Standard food can dimensions range from about 2.69 inches in diameter for a picnic can up to 6-3/16 inches for a #10 can. Heights range from roughly 1.5 inches to 7 inches, depending on size and use.
This guide covers every standard food can size, from the tiny picnic can to the massive #10 can, plus safety and storage tips most guides skip.
What Are Food Can Dimensions?
Food can dimensions simply mean two numbers: diameter and height, both measured in inches. Diameter is the width across the lid. Height is the distance from the bottom to the top rim.
Manufacturers also use a can code, like 401×411, to describe size without spelling it out. It looks confusing at first, but it’s actually simple math.
How to Read Food Can Size Codes
Each number in a can code represents inches and sixteenths of an inch. A code of 401×411 means the can is 4 and 1/16 inches in diameter and 4 and 11/16 inches tall.
The first two digits are whole inches. The last two digits are sixteenths. This system, set by the Can Manufacturers Institute (CMI), keeps sizing consistent across every US can maker.

Food Can Sizes Explained
Picnic and Small Food Can Dimensions
The picnic can measures about 2.69 inches wide and 4 inches tall, holding 10 to 12 ounces. You’ll spot this size on tuna, condensed soup, and small vegetable portions.
Even smaller is the baby food and tomato paste can, around 2 11/16 inches wide and just over 1 inch tall. It’s built for single-use, low-waste portions.
#300 and #303 Can Dimensions
The #300 can stands 3 inches wide and 4-7/16 inches tall, holding 15 to 16 ounces. It’s the classic soup and bean can found in nearly every US pantry.
The #303 can is slightly wider at 3-3/16 inches and holds 16 to 17 ounces — exactly 2 cups. That makes it a favorite for stewed tomatoes and canned fruit.
#2 and #2.5 Can Dimensions
A #2 can measures 4 inches in diameter and holds about 20 ounces, typically used for fruit and vegetables. It’s one of the most recognized sizes on grocery shelves.
The #2.5 can steps up to 4-1/16 inches wide and 4-11/16 inches tall, holding 26 to 30 ounces. Bakeries lean on this size for pie filling and pineapple.
#3 and #5 Can Dimensions
The #3 cylinder can holds around 46 ounces of juice or bulk fruit, with a 4-1/4 inch diameter. It bridges the gap between retail and foodservice sizing.
The #5 can is built for volume — 5 to 6 inches wide, holding 56 ounces. Restaurants and institutional kitchens use it for chili and bulk soup.
#10 Can Dimensions (The Foodservice Standard)
The #10 can is the giant of the lineup: 6-3/16 inches in diameter and 7 inches tall, holding 100 to 110 fluid ounces — nearly 13 cups. Schools, hospitals, and restaurants rely on it daily.
This size cuts cost per ounce and reduces how often staff reorder supplies. Once opened, though, it needs quick use or refrigeration to stay fresh.

How to Substitute Can Sizes in a Recipe
Running low on the exact can size a recipe calls for isn’t a dealbreaker. You can combine two smaller cans to match a larger one’s volume.
For example, two 8 oz cans roughly equal one 15 oz can. Just check the total ounces on the label before swapping, since drained weight can vary between brands.
What Are Food Cans Made Of?
Most food cans are made from tinplate, which is steel coated with a thin layer of tin. This coating stops rust and keeps food from reacting with the metal.
Aluminum is the other common choice, mostly for smaller cans and beverages. It’s lighter than tinplate and naturally resists corrosion.
Two-Piece vs. Three-Piece Can Construction
A two-piece can is pressed from a single sheet of metal, so the body and bottom form one seamless piece. Only the lid gets sealed on after filling, which makes it stronger under pressure.
A three-piece can uses a separate body, top, and bottom, joined with a welded side seam. Most vegetable and fruit cans use this build because it’s cheaper and easier to customize.
How to Measure a Food Can Correctly
Measuring a can yourself is simple with just a ruler or tape measure. Measure diameter straight across the lid, avoiding the raised seam.
For height, measure from the flat bottom to the top edge. Round to the nearest 1/16 inch for accuracy that matches industry standards.
Food Can Storage and Shelf Life Tips
Store cans in a cool, dry spot away from direct sunlight and temperature swings. Heat speeds up can corrosion and shortens shelf life.
Most high-acid foods, like tomatoes, last 12 to 18 months. Low-acid foods, like beans and vegetables, can safely stay fresh 2 to 5 years when stored properly.

Why is a #10 can called a #10 can?
The #10 can name comes from an older can-sizing system used decades ago by US manufacturers, not from its capacity or a metric measurement. The name stuck even after sizing methods changed, and it’s now the standard term for the large 100+ ounce foodservice can..
