Here is what you need to know about determining serving sizes for Nutrition Facts labels.
Serving Sizes are based on "Reference Amounts".
Serving Sizes are usually expressed in whole numbers. For products that are sold in large discrete units and divided for consumption, use fractions such as 1/2, 1/3, 1/4 or smaller fractions that can be generated by further division by 2 or 3.
Decimals are not allowed in serving sizes.
Note that there is an exception to the use of reference amounts. For example, the reference amount for muffins is 55g (about 2oz). If you make a 4oz muffin, and you reasonably expect the consumer to eat the entire muffin at one sitting, you should set the serving size to one muffin.
Once you have determined the appropriate serving size for your product, refer to the article Specifying Serving Size for Nutrition Reports.
