Average Cocktail Size.

A standard cocktail glass contains 90 to 300 millilitres (3 to 10 oz), though originally they were around 120 millilitres (4 oz) in size.

Oversized cocktail glasses, ranging in capacity from 180 ml (6 oz) to large glasses of 350 ml (12 oz) or more are available.

Cocktail Glasses

A cocktail glass is a stemmed glass with an inverted cone bowl, mainly used to serve straight-up cocktails.


The term cocktail glass is often used interchangeably with martini glass, despite their differing slightly.

Calculating Cocktail 

Alcohol Content.

To workout the alcohol percentage, just multiply the volume of the alcohol, 55ml shot in this case, by the alcohol content (ABV) as a percentage.


i.e. 40% you multiply by 0.4 and 35% by 0.35 and 20% by 0.2, etc. Then divide this number by the total volume of the drink/cocktail, in this case is 150ml.

55 x 0.4 / 150ml x 100 = 14.66% 

What is an alcohol unit?

One unit is 10ml or 8g of pure alcohol. Because alcoholic drinks come in different strengths and sizes, units are a way to tell how strong your drink is.

It takes an average adult around an hour to process one unit of alcohol so that there's none left in their bloodstream, although this varies from person to person.

Using units is a simpler way of representing a drink's alcohol content – usually expressed by the standard measure alcohol by volume (ABV).

ABV is a measure of the amount of pure alcohol as a percentage of the total volume of liquid in a drink.

You can find the ABV on the labels of cans and bottles, sometimes written as "vol" or "alcohol volume", or if you are out and about, you can ask bar staff about particular drinks.

For example, wine that says "12% ABV" or "alcohol volume 12%" means 12% of the volume of that drink is pure alcohol.

You can work out how many units there are in any drink by multiplying the total volume of a drink (in ml) by its ABV (measured as a percentage) and dividing the result by 1,000.

  • strength (ABV) x volume (ml) ÷ 1,000 = unit

For example, to work out the number of units in a pint (568ml) of strong lager (ABV 5.2%):

  • 5.2 (%) x 568 (ml) ÷ 1,000 = 2.95 units
