The humble can of tomatoes is a pantry staple for countless home cooks and professional chefs alike. Its versatility makes it an indispensable ingredient in everything from hearty pasta sauces to comforting stews and vibrant salsas. But standing in the grocery aisle, faced with rows upon rows of tomato cans, can be surprisingly overwhelming. One of the first questions that invariably pops up is: “How big is a can of tomatoes, really?”
This article aims to demystify the world of canned tomato sizes, providing a comprehensive guide to understanding the different volumes, weights, and common uses associated with each standard can size. By the end, you’ll be able to confidently choose the right can of tomatoes for any recipe, eliminating guesswork and ensuring culinary success.
Understanding Standard Can Sizes for Tomatoes
Canned goods, including tomatoes, are packaged in standardized can sizes established by industry conventions and regulations. These sizes are typically referred to by their “trade size” or “designation,” which may not directly correspond to the actual net weight or volume inside. It’s crucial to understand the common designations and their approximate equivalents in both weight and volume to make informed decisions while cooking.
The 14.5-Ounce Can: A Versatile All-Arounder
The 14.5-ounce can is perhaps the most common and versatile size you’ll encounter. It’s the go-to choice for a wide range of recipes, striking a balance between quantity and convenience. This size is suitable for smaller families or when you only need a moderate amount of tomatoes for a particular dish.
Generally, a 14.5-ounce can of tomatoes contains approximately 1 ¾ cups of product. The net weight is, as the name suggests, 14.5 ounces (or about 411 grams). These cans are readily available in various forms, including diced, whole peeled, crushed, stewed, and puréed, giving you plenty of options depending on your culinary needs.
You might use a 14.5-ounce can for making a small batch of pasta sauce, adding to chili, thickening soups, or preparing enchilada sauce. The convenient size makes it perfect for quick weeknight meals and single-serving recipes.
The 28-Ounce Can: For Family Meals and Batch Cooking
Stepping up in size, the 28-ounce can is a popular choice for larger families or when you’re planning to batch cook and freeze portions for later use. This size offers a significant increase in volume compared to the 14.5-ounce can, making it ideal for recipes that call for a substantial amount of tomatoes.
A 28-ounce can of tomatoes holds approximately 3 ½ cups of product. The net weight is, predictably, 28 ounces (or roughly 794 grams). Similar to the smaller size, 28-ounce cans are available in various forms, including whole peeled, crushed, diced, and puréed.
Consider using a 28-ounce can when making a large pot of spaghetti sauce, a hearty stew, a flavorful tomato soup, or a big batch of salsa. The larger quantity is also perfect for canning your own tomato-based sauces or preserving tomatoes for the winter months.
The 15-Ounce Can: A Close Cousin with a Slight Difference
While the 14.5-ounce can is the most prevalent, you may also encounter 15-ounce cans of tomato sauce. The difference is minimal, and in most recipes, you can easily substitute one for the other without noticing a significant change in the outcome.
A 15-ounce can of tomato sauce contains almost 1 7/8 cups and the net weight is approximately 425 grams. This size is primarily for tomato sauce rather than diced or whole tomatoes.
The 6-Ounce Can: Tomato Paste Powerhouse
Tomato paste typically comes in smaller cans, with the 6-ounce can being the most common. Tomato paste is a concentrated form of tomatoes, offering an intense flavor and thickening properties to sauces and stews. A little goes a long way, making the small can size perfectly suited for its purpose.
A 6-ounce can of tomato paste contains approximately ¾ cup of product. The net weight is 6 ounces (or around 170 grams). Because of its concentrated nature, tomato paste is usually used in smaller quantities than other forms of canned tomatoes.
Use a 6-ounce can of tomato paste to deepen the flavor of pasta sauces, thicken stews and soups, add richness to braised dishes, or create a base for barbecue sauces. Its intense flavor makes it a valuable ingredient in a wide range of savory recipes.
The 10-Ounce Can: Diced Tomatoes and Green Chilies
The 10-ounce can is often used for specialty tomato products, such as diced tomatoes with green chilies. This combination adds both tomato flavor and a spicy kick to dishes, making it a convenient option for Southwestern and Mexican-inspired cuisine.
A 10-ounce can holds approximately 1 ¼ cups. While less common than other sizes for plain tomatoes, its specific combination of tomatoes and chilies makes it a handy pantry staple for certain types of cooking.
Use a 10-ounce can of diced tomatoes with green chilies in chili, quesadillas, salsa, dips, or to add a flavorful boost to scrambled eggs or omelets. The added chilies bring a pleasant heat and complexity to your dishes.
Larger Cans: For Commercial Use and Big Batches
While the sizes discussed above are the most common for home cooks, larger cans of tomatoes are available, primarily for commercial use in restaurants, catering services, and food processing plants. These cans can range in size from 35 ounces to over 100 ounces, offering significant cost savings for those who use tomatoes in large quantities.
For instance, a #10 can, which is a common commercial size, holds approximately 109 ounces (or 6 lbs 13 oz). This translates to roughly 13 cups.
A Table for Quick Reference
The table below summarizes the most common can sizes for tomatoes, their approximate volume in cups, and their common uses:
| Can Size | Approximate Volume | Common Uses |
|---|---|---|
| 6-ounce (Tomato Paste) | ¾ cup | Flavoring sauces, thickening stews, barbecue sauce base |

Choosing the Right Type of Canned Tomatoes
Beyond the size of the can, the type of canned tomatoes you choose also plays a crucial role in the outcome of your dishes. Different types of canned tomatoes are processed and prepared in various ways, each offering unique textures and flavors.
- Whole Peeled Tomatoes: These are typically packed in tomato juice or purée. They are the most versatile option, as you can crush, chop, or purée them to your desired consistency. They are ideal for recipes where you want to control the texture of the tomatoes.
- Diced Tomatoes: These are pre-cut into small cubes, making them convenient for recipes where you want a chunky tomato texture. They are often packed in tomato juice or purée.
- Crushed Tomatoes: These have a coarser texture than purée but are smoother than diced tomatoes. They are a great choice for sauces and soups where you want a slightly rustic texture.
- Tomato Purée: This is a smooth, thick tomato product made from cooked and strained tomatoes. It’s ideal for thickening sauces and adding a concentrated tomato flavor.
- Tomato Paste: As mentioned earlier, tomato paste is a highly concentrated form of tomatoes, used to add intense flavor and thickening properties.
- Stewed Tomatoes: These are whole or diced tomatoes that have been cooked with seasonings, such as onions, celery, and peppers. They are a convenient option for adding both tomato flavor and vegetables to dishes.
- Tomato Sauce: A cooked and seasoned tomato product, often used as a base for pizza sauce or pasta sauce.
Tips for Using Canned Tomatoes
To get the most out of your canned tomatoes, keep these tips in mind:
- Check the expiration date: While canned goods have a long shelf life, it’s always best to use them before the expiration date to ensure optimal flavor and quality.
- Look for high-quality brands: The quality of canned tomatoes can vary significantly between brands. Look for brands that use ripe, flavorful tomatoes and minimal additives.
- Taste before adding: Canned tomatoes can sometimes have a slightly metallic taste. Taste them before adding them to your dish and adjust seasonings accordingly.
- Don’t discard the juice: The juice in the can is packed with flavor and can be used in your recipe.
- Store opened cans properly: Once opened, transfer any unused tomatoes to an airtight container and refrigerate. Use within a few days.
Canned Tomatoes: A Sustainable Choice
Canned tomatoes offer a sustainable alternative to fresh tomatoes, especially during the off-season. Canned tomatoes are often processed and packaged close to where they are grown, reducing transportation costs and emissions. The canning process also helps to preserve tomatoes for longer, reducing food waste.
In conclusion, understanding the different sizes and types of canned tomatoes available empowers you to make informed choices in the kitchen. By knowing the approximate volume of each can size and the characteristics of different tomato products, you can confidently select the perfect ingredients for your recipes, ensuring delicious and satisfying results every time. So, the next time you’re faced with a wall of tomato cans, you’ll be equipped with the knowledge to choose the right one for the job.
What are the standard sizes of canned tomatoes available in stores?
Canned tomatoes come in a range of sizes, typically measured by weight. The most common sizes include 14.5 ounces (often labeled as “small” or “regular”), 28 ounces (considered “large” or “family-size”), and 10-12 ounces (sometimes found in diced or stewed varieties). You may also encounter smaller cans around 6-8 ounces, and larger “institutional” sizes, but these are less frequent in regular grocery stores.
The specific weight can vary slightly between brands, but these are the general guidelines you can use when shopping. Always check the label for the exact weight and the type of tomatoes inside, as this impacts both the amount and the suitability for your recipe. Understanding these standard sizes helps you purchase the correct amount for your cooking needs.
What types of canned tomatoes are typically sold?
Aside from size, canned tomatoes are sold in various forms, each suited to different culinary applications. Diced tomatoes are pre-cut into small cubes, often with added seasonings or juice. Whole peeled tomatoes come whole, immersed in tomato juice or purée, and are easily crushed or chopped to your desired consistency.
Crushed tomatoes offer a smoother texture than diced, while tomato purée is a smooth, thick sauce made from cooked and strained tomatoes. Tomato paste is a highly concentrated form of tomatoes, used for thickening sauces and intensifying flavor. Finally, stewed tomatoes often contain added vegetables and seasonings, making them a convenient component for stews and casseroles.
How do I choose the right size and type of canned tomatoes for a specific recipe?
The recipe itself is the best guide for choosing the appropriate size and type of canned tomatoes. Recipes that call for a specific weight, such as “28 ounces of crushed tomatoes,” leave little room for interpretation. For other recipes, consider the desired texture and flavor profile.
If you need smooth, rich sauce, use crushed tomatoes or purée. For a chunky texture, opt for diced or whole peeled tomatoes that you can crush yourself. A general rule of thumb is to use smaller cans for single-serving meals or to avoid leftovers, and larger cans for feeding a family or making big batches of sauce.
Can I substitute one size of canned tomatoes for another?
Yes, you can usually substitute one size of canned tomatoes for another, but you might need to adjust other ingredients in the recipe. If a recipe calls for a 28-ounce can and you only have two 14.5-ounce cans, those are generally equivalent and can be used in their place.
However, remember to account for the liquids as well. If the recipe specifies reducing the sauce, using more liquid (from smaller cans) may require a longer cooking time. Always taste and adjust seasonings as needed to maintain the intended flavor.
How should I store leftover canned tomatoes?
Once opened, canned tomatoes should be transferred to an airtight container and refrigerated immediately. The acidity of the tomatoes can react with the can lining, potentially affecting the flavor and safety of the remaining contents if left in the can.
Glass or plastic containers with tight-fitting lids are ideal for storing leftover tomatoes. They can typically be stored in the refrigerator for up to 5-7 days. Be sure to check for any signs of spoilage, such as mold or an off odor, before using them.
What is the shelf life of unopened canned tomatoes?
Unopened canned tomatoes have a relatively long shelf life, typically lasting for 1-2 years beyond the printed “best by” or “use by” date on the can. This date indicates the manufacturer’s estimate of peak quality, but the tomatoes are usually safe to consume beyond that date.
Store unopened cans in a cool, dry place away from direct sunlight. Regularly inspect the cans for any signs of damage, such as dents, bulges, or rust. If a can is damaged, discard it immediately, as this can compromise the integrity of the seal and the safety of the contents.
Are there any health considerations when choosing canned tomatoes?
When choosing canned tomatoes, be mindful of the sodium content, as some brands add salt during the canning process. Opt for “no salt added” or “low sodium” varieties to control your salt intake, especially if you are following a sodium-restricted diet.
Also, consider the lining of the can. While most modern cans are lined with BPA-free materials, it’s worth checking the label to ensure it. Choose products that emphasize sustainability and use BPA-free linings to minimize potential health risks associated with BPA exposure.
