The net quantity of contents statement (“Net Wt 8 oz (227 g)” and its variants) has to sit in the bottom 30% of the principal display panel, running parallel to the package’s base, in type sized to the panel’s area: 1/16 inch on a small panel, up to 1/2 inch on a panel larger than 400 square inches. That’s 21 CFR 101.7, the FDA’s implementing regulation under the Fair Packaging and Labeling Act. Weight is declared in avoirdupois pounds and ounces (or U.S. gallons for liquids); FDA’s regulation treats a metric equivalent as optional, while the Fair Packaging and Labeling Act (15 U.S.C. 1453(a)(2)) calls for both inch-pound and metric units on most consumer packages.
| Quick facts | Net quantity statement |
|---|---|
| Regulation | 21 CFR 101.7 |
| Applies to | The net quantity of contents statement on any packaged food's principal display panel |
| Key numbers | Bottom 30% placement; type size 1/16 in to 1/2 in by PDP area; metric optional under 101.7(p) but called for by the FPLA |
The rule
21 CFR 101.7(f) sets the placement: the net quantity declaration must appear “within the bottom 30 percent of the area of the label panel in lines generally parallel to the base on which the package rests,” so a shopper scanning the front of a package always finds it in roughly the same spot. Packages whose principal display panel is 5 square inches or less are exempt from that placement requirement, since there’s little room to enforce a strict zone on a very small label.
For units, 101.7(b) requires weight to be stated “in terms of avoirdupois pound and ounce,” and fluid measure “in terms of the U.S. gallon” and its subdivisions. Numerical count, under 101.7(c), can stand alone only if the count itself gives a shopper adequate information about quantity; otherwise it has to be combined with a weight, measure, or size statement for the individual units. Metric units are addressed separately in 101.7(p), which lets you add an accurate metric statement alongside the U.S. customary one. The FPLA goes further and calls for both systems on most consumer packages, so printing both is the reading that satisfies the statute and the regulation together.
Wording matters too. Per 101.7(j), a weight declaration uses the term “net weight.” For fluid measure or count, “net” or “net contents” is optional phrasing rather than a fixed requirement.
The numbers
The type size for the net quantity statement scales directly with the size of your principal display panel, under 101.7(i):
| Principal display panel area | Minimum type size |
|---|---|
| 5 sq in or less | 1/16 inch |
| More than 5, up to 25 sq in | 1/8 inch |
| More than 25, up to 100 sq in | 3/16 inch |
| More than 100 sq in | 1/4 inch |
| More than 400 sq in | 1/2 inch |
Note that the “more than 100” tier and the “more than 400” tier are written as one paragraph in the regulation: 1/4 inch applies above 100 square inches, except the minimum steps up to 1/2 inch once the panel passes 400 square inches (21 CFR 101.7(i)(4)).
On the label
A 5 fl oz bottle of hot sauce has a principal display panel well under 25 square inches; call it 8 square inches. Its net quantity statement, “Net 5 fl oz (148 mL)” (fluid measure for a liquid; “Net Wt” is only for weight), needs to be at least 1/8 inch tall and sit in the bottom 30% of that panel, running parallel to the bottle’s base, not printed sideways along a curved shoulder label. A large jar of pasta sauce with a 30-square-inch front panel needs the same statement in at least 3/16 inch type. Both bottles should show the metric amount alongside the U.S. units: the Fair Packaging and Labeling Act has required both since its 1992 amendment, and FDA’s labeling guidance says to declare both (FDA).
A wrong version places “Net 5 fl oz” in a decorative script font at the very top of the hot sauce label, in type that measures closer to 1/16 inch even though the panel size calls for 1/8 inch. It is technically present, but neither correctly sized nor correctly placed.
Mistakes we see
- Wrong type size for the panel’s actual area. Defaulting to the smallest size across every SKU instead of recalculating for each panel size.
- Placement outside the bottom 30%. A net quantity statement wrapped around curved packaging, printed at the top, or worked into a logo instead of sitting in the correct zone.
- Dropping metric because 101.7(p) calls it optional. The Fair Packaging and Labeling Act (15 U.S.C. 1453(a)(2)) calls for both inch-pound and metric units on most consumer packages, so most labels print both.
- Using “Net Weight” for a fluid product, or omitting “net weight” entirely for a solid product where the term is required.
- Numerical count with no other context, such as “24 count” on a package where the count alone doesn’t tell a shopper how much product that actually is.
Related rules
Net quantity placement works alongside the broader rules for the principal display panel and general type size and placement standards elsewhere on the label. It’s independent of the ingredient statement, which lives on the information panel rather than the PDP, and common net quantity errors are also covered on label mistakes.
Build it right
NutriLabels’ builder calculates the correct net quantity type size for your package’s principal display panel automatically and places the statement where 21 CFR 101.7 requires.
A net quantity sized and placed right the first time lets your front-panel design go to print as drawn. Enter your recipe and package size, then see your label: free with no card required, you see your calories, the claims you qualify for, your allergen line and the nutrient to watch, and every other value and %DV stays hidden until you unlock it. $29 unlocks every other nutrient value and %DV, every FDA format your product qualifies for, and your ingredient statement and allergen declaration, ready to print. Start your label or read the principal display panel rules that sit around it.
FAQ
Where does the net quantity statement have to go on the package?
In the bottom 30% of the principal display panel, in lines running parallel to the base the package rests on, per 21 CFR 101.7(f). Packages with a principal display panel of 5 square inches or less are exempt from this placement requirement.
How big does the net quantity text have to be?
It scales with your principal display panel's area, from 1/16 inch on panels of 5 square inches or less up to 1/2 inch on panels larger than 400 square inches, under 21 CFR 101.7(i).
Do I have to declare weight in both pounds/ounces and metric units?
The two rules read differently. FDA's regulation, 21 CFR 101.7(b), calls for avoirdupois pounds and ounces (or U.S. gallons for fluid measure) and treats a metric statement as optional under 101.7(p). The Fair Packaging and Labeling Act itself (15 U.S.C. 1453(a)(2)) calls for both the inch-pound and the SI metric units on most consumer packages, which is why most retail labels show both, as in 'Net Wt 8 oz (227 g)'.
Should I use 'Net Wt' or 'Net Weight'?
For products declared by weight, 21 CFR 101.7(j) calls for 'net weight.' For fluid measure or numerical count, the words 'net' or 'net contents' are optional.
Is this the same rule as 21 CFR 101.105?
No. That citation doesn't govern net quantity of contents in the current Code of Federal Regulations. The operative FDA rule for net quantity placement, wording, and type size is 21 CFR 101.7.
