Cosmetic pack sizes are quoted in ml, in grams and in fluid ounces depending on the market and the product. This converts between them and shows what each size is normally used for.
| Capacity | |
| Equals | — |
ml ↔ g is treated as 1:1, which is right for water-like formulas and wrong for oils (≈0.9 g/ml) and for powders. fl oz (US) = 29.5735 ml; fl oz (UK) = 28.4131 ml.
These are the sizes our 3134 stock moulds cover, grouped by what the fill normally is. Sizing the pack to the dose is the first commercial decision in a packaging project — see capacity by product form.
| Facial serum, oil serum | 15 · 20 · 30 ml | 0.5–1.0 fl oz |
| Eye cream, spot treatment | 15 · 20 · 30 g | 0.5–1.0 fl oz |
| Face cream, moisturiser | 30 · 50 g | 1.0–1.7 fl oz |
| Cleanser, micellar, toner | 120 · 150 · 200 · 300 ml | 4.0–10.1 fl oz |
| Body lotion, body wash | 200 · 250 · 300 · 500 ml | 6.8–16.9 fl oz |

| Travel and sample | 20 · 30 ml | 0.7–1.0 fl oz |
A 30 ml airless bottle is filled to roughly 27–29 ml so the piston has travel, and a 50 g jar is filled to about 45–48 g so the lid does not touch the product. The nominal capacity printed on the pack should be the labelled net content, which must be legally correct for the market — not the mould's headline number. Confirm the fill volume against the mould before you approve artwork.
Send the product form and the target price point — the capacity follows from both, and we quote the pack and the fill together within 24 hours.
