Quick answer

The net quantity of contents is the statement of how much product is in the package, such as 100 tablets or a net weight in ounces and grams. It goes on the front panel, within the bottom 30% of it, and counts only the product, not the container or packing material.1,2

Key facts

  • It is stated by weight, measure, numerical count, or count combined with weight or measure; solids by weight and liquids by fluid measure.2
  • Weight or measure statements give both metric and US customary units, such as grams and ounces.1
  • The term net weight must be used for weight; net or net contents is optional for fluid measure and counts.2
  • Words that exaggerate the amount, such as jumbo quart or full gallon, are not allowed.2
  • The minimum type height depends on the front panel's area, from 1/16 inch on panels of 5 square inches or less up to 1/2 inch on panels over 400 square inches.1,2

Where it goes and how it looks

  • On the principal display panel, the part of the package most likely to be seen at purchase, and repeated on any alternate front panels.2,3
  • As a distinct item in the bottom 30 percent of that panel, in lines roughly parallel to the base. Panels of 5 square inches or less are exempt from the bottom 30 percent rule.2
  • In bold, easy to read type that contrasts with the background, with set spaces around it.2

Count, weight or both

A count works for tablets and capsules, for example 100 tablets. When a count alone would not give enough information, it must be combined with the weight, measure or size of the units. A powder, being a solid, is stated by weight.1,2

Weight means the product only. Wrappers and packing material are left out, except that for products sold under pressure, such as sprays, the propellant is included.1,2

Net quantity versus servings

The net quantity describes the whole package and the serving size describes one use. When they say the same thing, as with 100 tablets and a 1 tablet serving, the Supplement Facts panel can leave out Servings Per Container.4,5

The declaration must be accurate. FDA allows reasonable variation from moisture lost or gained during normal distribution, or from unavoidable deviations in good manufacturing practice, but not variation that is unreasonably large.2

Questions people ask

What does net weight mean?

The weight of the product itself, without the container, wrappers or packing. Packages under 4 pounds show ounces, with pounds added in parentheses from 1 pound up.2

Is the net quantity the same as servings per container?

Not always. For a 100 tablet bottle with a 2 tablet serving, the net quantity is 100 tablets and the panel shows 50 servings per container.4,5
