Watermelon serving size: 10 oz (280g). FDA files watermelon under “Watermelon”, whose reference amount customarily consumed (RACC) is 280 g. The serving on your Nutrition Facts panel is the household measure closest to that reference amount, written as the measure followed by its metric weight.
The declaration
| FDA category | Fruits and Fruit Juices: Watermelon |
| Reference amount (RACC) | 280 g |
| FDA label statement | See footnote 12 |
| Serving size declaration | 10 oz (280g) |
| Single-serving container | Any package under 560 g (20 oz) is one serving: the whole package is the serving size (21 CFR 101.9(b)(6)). |
| Dual-column panel | Packages holding 560 g–840 g (20 oz–30 oz) must show a second column for the whole package (21 CFR 101.9(b)(12)). |
Servings per container
| Package | Serving size | Servings per container |
|---|---|---|
| 8 oz (227 g) | 1 package (227g) | 1 (single-serving container) |
| 12 oz (340 g) | 1 package (340g) | 1 (single-serving container) |
| 16 oz (454 g) | 1 package (454g) | 1 (single-serving container) |
| 24 oz (680 g) | 10 oz (280g) | about 2.5 · dual column |
| 32 oz (907 g) | 10 oz (280g) | about 3 |
Servings are rounded exactly as 21 CFR 101.9(b)(8) requires: to the nearest whole number, except between 2 and 5 servings, which round to the nearest half; “about” marks any rounding.
What this means for your label
- Declare the serving as 10 oz followed by its weight in grams, for example “10 oz (280g)”.
- Cups are written in 1/4- or 1/3-cup steps; tablespoons as 1, 1 1/3, 1 1/2, 1 2/3, 2 or 3; teaspoons as 1/8, 1/4, 1/2, 3/4, 1 or 2 (21 CFR 101.9(b)(5)(i)). Any other increment is not permitted.
- A package under 560 g is one serving no matter what: the panel reads “1 serving per container” and the serving size is the whole package.
- All the nutrient values on the panel are per this serving, rounded by 21 CFR 101.9(c). Change the serving and every number changes with it.
