FDA net quantity declarations, in plain language
The useful question is not simply whether a package says “net weight.” It is whether the label communicates the quantity of food, in the appropriate units, in the required place, and at a readable size under the rules that apply to that product and package.
A net quantity-of-contents statement tells consumers how much food is in the package. Under 21 CFR § 101.7, it is expressed by weight, measure, numerical count, or an applicable combination—and the quantity excludes wrappers and other material packed with the food.
For many packaged foods, the right expression depends first on the physical form of the product, then on how the statement appears on the principal display panel. The rule addresses the quantity basis, location, separation, contrast, proportions, and minimum letter height.
This guide is an educational summary for FDA-regulated packaged foods. Product-specific requirements and exceptions should be checked against the current eCFR text and applicable official guidance.
Quantity basis · Placement · Readability
Start with the current rule, not a copied example. The examples below explain the structure of the requirement; they are not a substitute for reviewing the specific product and package.
The rule generally uses fluid measure for liquids and weight for solid, semisolid, viscous, or mixed solid-and-liquid foods. Numerical count or dry measure applies in the circumstances the rule describes.
“Net weight” is not the universal expression for every packaged food. The product form and applicable rule determine the quantity basis.
The declaration appears as a distinct item on the principal display panel, separated from surrounding label information and generally within the bottom 30 percent in lines parallel to the package base.
For a principal display panel of 5 square inches or less, the bottom-30-percent placement rule does not apply when the declaration meets the other requirements.
The declaration must be conspicuous, easily legible, boldface, and in distinct contrast. Minimum letter height is tied to the area of the principal display panel.
FDA’s metric policy includes examples such as Net Weight 15 oz (425 g). The exact expression depends on the applicable unit and package.
The declaration must accurately reveal the quantity of food in the package, exclusive of wrappers and other material packed with it. Package-content testing is a separate subject addressed through the applicable authorities and testing procedures.
Under 21 CFR § 101.7, the minimum letter height changes with the size of the principal display panel. These thresholds do not replace the separate legibility, contrast, spacing, and proportion requirements in the rule.
| Principal display panel area | Minimum letter height |
|---|---|
| 5 square inches or less | 1/16 inch |
| More than 5 through 25 square inches | 1/8 inch |
| More than 25 through 100 square inches | 3/16 inch |
| More than 100 through 400 square inches | 1/4 inch |
| More than 400 square inches | 1/2 inch |
The eCFR also addresses contrast, letter proportions, lower-case measurement, fractions, and increased size when the declaration is blown, embossed, or molded rather than printed.
Section 101.7 states that the declaration must accurately reveal the quantity of food in the package, excluding wrappers and other packed-with material. It does not support replacing a product-specific assessment with a single, unsourced “allowable tolerance.”
Use the current regulation to review the declaration’s quantity basis, location, format, legibility, and size requirements.
FDA’s Food Labeling Guide and metric policy organize common questions and examples, but the current regulation remains the governing starting point.

No. Section 101.7 says the declaration must accurately reveal the quantity of food in the package, exclusive of wrappers and other material packed with it. Check the current rule and applicable guidance for product-specific questions.
For a package with a principal display panel of 5 square inches or less, the rule provides an exception from the bottom-30-percent placement requirement when the declaration meets the other applicable requirements. It is not a general exemption from making the declaration.
The rule generally uses fluid measure for liquids and weight for solid, semisolid, viscous, or mixed solid-and-liquid foods. Numerical count or dry measure applies in the circumstances described by the rule.
Minimum letter height is tied to the area of the principal display panel. Under § 101.7, the thresholds range from 1/16 inch on panels of 5 square inches or less to 1/2 inch when the panel area exceeds 400 square inches.
