- 1Enter the Total Batch Quantity you made, and its Unit as free text (for example 'grams').
- 2Enter the Number of Servings you want to divide the batch into.
- 3Read the Portion Size per Serving below.
The Serving Size Calculator divides a total batch quantity evenly across a number of servings to tell you how much is in each portion. It distinguishes three things: the Total Batch Quantity (the whole amount you made), the Number of Servings (how many portions you split it into), and the Portion Size per Serving (the result — the amount in each portion). It does not calculate nutrition; it only calculates a quantity per serving.
The single calculation performed.
Serving Size = Total Batch Quantity ÷ Number of ServingsThe Unit field is a plain text label shared by the batch quantity and the result.
Displayed Unit = whatever you typed (no conversion)Serving Size = 1200 ÷ 6 = 200Serving Size = 2 ÷ 8 = 0.25Serving Size = 750 ÷ 5 = 150- Total Batch Quantity and Number of Servings must both be greater than zero, or the calculator shows no result.
- The calculator assumes the batch divides evenly — it does not account for cooking loss, evaporation, or uneven portioning.
- The Unit field is a plain text label carried through unchanged; it is not converted.
- This tool reports portion size only. It does not calculate calories or any nutritional information.
- Number of Servings accepts decimals in the input field, though in practice it is usually a whole number of portions.
How do I calculate the size of one serving?
Divide the Total Batch Quantity by the Number of Servings: Serving Size = Total Batch Quantity ÷ Number of Servings.
What is the difference between total quantity, servings, and portion size?
Total Batch Quantity is the whole amount you made; Number of Servings is how many portions you split it into; Portion Size per Serving is the result — the amount in each portion.
Does this calculator show calories or nutrition per serving?
No. It only calculates the physical quantity (weight or volume) per serving, not nutritional content.
What units can I use?
Any unit you like — the Unit field is a plain text label (for example grams, ml, oz). It is not converted, just displayed with the result.
Why does the calculator show no result?
Total Batch Quantity and Number of Servings must both be greater than zero.
