Different Sizes of Cans
(revised: 21 April 1998)

The size of a can, i.e. the liquid volume it holds or capacity, ranges from the tiny 135 ml. mini-cans to the huge 5-litre (5.000 ml.) barrels.
Measures are commonly expressed in centilitres (cl.) or in millilitres (ml.), except in the U.S.A. were capacity is given in fluid ounzes (fl.oz.); one fl.oz. is equals to 29.6 ml.
In Argentina cubic centimetres (cm³ or cc.) are used instead of millilitres.
Usually each country has a standard size, and eventually one or more less common "minor" sizes, in some cases typical of one specific country.

What changes in different sizes is mainly the height of the can, since most of them have the same width or diameter: 6.5 cm. (see picture). But some particular sizes have also a different width, usually smaller than the standard.
For this reason, cans with the same capacity might have different dimensions.
The picture shows a comparison of all capacities within 500 ml., in actual size. They are expressed in ml. or in fl.oz. according to which of the two measures is more often stated on each of the cans.

DRAUGHT CANS

Since the early '90s, many British brands have started producing "draught cans": they contain a special plastic device which releases gas just as from a beer pump when the can is opened (instructions about how to cool and pour the beer often appear on the back of the can). Most of these specimens are 440 ml. in size, but because of the plastic widget inside the can they are taller (i.e. the actual size of an ordinary 500 ml. can). More recently, the same device has been also used for 330 ml. cans, which therefore look as tall as 375 ml. ones.
For this reason, it is always better to check the capacity stated on the can itself, rather than guessing by the size of the specimen.
