## 1. Executive Summary & Core Engineering Scope
Perfume bottle sizes in ml and oz — 1 oz / 30 ml, 1.7 oz / 50 ml, 3.4 oz / 100 ml plus 1.5–10 ml discovery sizes — with sprays per bottle at 0.1–0.2 ml per shot, typical flacon dimensions, neck finishes, and which size an indie brand should launch first based on MOQ and mould logic.

Every perfume shelf runs on three numbers — 30, 50 and 100 ml, printed as 1 oz, 1.7 oz and 3.4 oz — with a discovery layer of 1.5–10 ml underneath. This guide converts each size, counts the sprays inside it, gives the typical flacon dimensions in millimetres, and explains why an indie brand almost always launches on 50 ml first: the answer is minimums and moulds, not marketing.

1 US fl oz = 29.5735 ml , so a 30 ml perfume is 1.01 oz (sold as 1 oz), 50 ml is 1.69 oz (1.7 oz) and 100 ml is 3.38 oz (3.4 oz). A fine-mist perfume pump delivers 0.1–0.2 ml per spray , so 30 ml gives 150–300 sprays, 50 ml 250–500 and 100 ml 500–1,000 ; a 5 ml travel spray gives 25–50 and a 2 ml vial 10–20. 100 ml is the ceiling because it is the carry-on liquids limit. Most indie brands launch on 50 ml because a stock 30 / 50 / 100 ml flacon family shares one neck — FEA 15 crimp or 15/415 / 18/415 screw — so one pump and one cap serve every size, and a stock flacon starts around 500–1,000 pieces with no mould.

US labels are printed in fluid ounces, EU and UK labels in millilitres, and the same bottle carries both. The conversion is fixed: fl oz = ml ÷ 29.5735. The rounding is what confuses people — 100 ml is 3.38 oz, but the label says 3.4 oz; 50 ml is 1.69 oz, labelled 1.7 oz; 30 ml is 1.01 oz, labelled 1 oz. A UK imperial fluid ounce is 28.4131 ml, which is why a "3.5 fl oz" imperial label can sit beside a "3.4 oz" US label on one 100 ml flacon.

Weight follows density, not volume. Alcohol-based fragrance sits near 0.85–0.90 g/ml , so a 100 ml eau de parfum weighs about 85–90 g of juice — and 250–450 g with the glass, which matters for freight and for how the bottle feels in hand. Perfume oils run 0.91–0.93 g/ml. If you need to move between ml, oz and grams for a spec sheet, the cosmetic packaging unit converter does it at your formula's density, and the cosmetic bottle size guide covers the skincare sizes alongside these.

A fragrance-grade fine-mist pump is specified at 0.1–0.2 ml (60–100 µl) per actuation , with dosing error held within 0.02 g; 12.5–24 mm sprayer sizes cover the range, and the pump is rated for at least 1,500 actuations. Divide the fill by the dose and you have the spray count. Two sprays a day empties a 30 ml in three to five months and a 100 ml in eight months to a year and a half — which is the real reason the three sizes map onto entry, hero and flagship price points.
