## 1. Executive Summary & Core Engineering Scope
How big is a 100 ml bottle, a 30 ml bottle, a 5 ml perfume? Fourteen cosmetic bottle sizes from 3 ml to 500 ml converted to US fl oz and grams, with typical height and diameter for glass serum bottles, PET bottles, perfume flacons and jars, the neck finish each size takes,

"How big is a 100 ml bottle?" is the most-asked question in cosmetic packaging and almost no supplier answers it in millimetres. This page does: fourteen sizes from 3 ml to 500 ml, each converted to US fluid ounces and grams, with the typical height and diameter of a glass serum bottle, a PET bottle, a perfume flacon and a jar at that capacity, what it looks like in an adult hand, and the neck finish it usually carries.

1 US fl oz = 29.5735 ml , so 30 ml ≈ 1 oz , 50 ml = 1.69 oz and 100 ml = 3.38 oz (labelled 3.4 oz) . A 100 ml cylindrical bottle is typically 42–48 mm across and 120–150 mm tall with its cap — about the height of a smartphone; a 30 ml serum dropper bottle is 30–33 mm across and 85–100 mm tall and disappears into a closed hand; a 5 ml perfume is 0.17 oz, about 50–60 mm tall . Water-based formulas weigh about 1 g per ml ; oils weigh 0.91–0.93 g per ml . 100 ml is the carry-on liquids ceiling in the US, EU and UK, which is why 30 / 50 / 100 ml dominate perfume and 15 / 30 / 50 ml dominate skincare.

Capacities are nominal. Fluid ounces are US customary (the figure printed on US labels); grams assume water at 20°C. Dimensions are the typical partner-factory range for a plain cylindrical bottle including its closure, because the same 30 ml can be a tall slim dropper or a squat perfume flacon and the two look nothing alike in hand. Where a format is not made at a size, the cell says so.

Two reading notes. First, the nominal size is not the brim-full volume: a bottle drawing carries a brim-full capacity held to ±5% and a fill line with headspace below it, so a "100 ml" bottle is a cavity of roughly 105–115 ml filled to 100. Second, the format changes the silhouette more than the capacity does. A 50 ml perfume flacon is wider than a 100 ml serum bottle, and a 50 ml cream jar is a puck 48–53 mm across and only 40–50 mm high. If a customer asks "how big", answer with the format first.

Three units describe one bottle, and they only agree for water.
