Why do soft drink cans are 330 ml.....

After the last class, this question really struck me on why do soft drinks cans are always at 330 ml not 300 ml or 350 ml. The question made me do lot of research to understand what's the logic behind the size. Internet threw lot of information about why it is, however nothing was convincing or conclusive enough to define the logic, however below are some interesting theories behind the 330 ml

• The one I find logical is that cola companies have 300 ml & 200 ml glass bottles and 500 ml to 2.5 liter pet bottles, hence the best size to come up for can is 330 ml which is 1/3rd of a liter and can be differentiated

• In North America, the standard can size is 12 fluid ounces (355 ml). In India and most of Europe, standard cans are 330 ml, which is approximately 1/3 of a liter. In Australia, the standard can size is 375 ml and in South Africa standard cans are 340 ml

• Other logic is, to reduce the package and transportation cost by packing a box of 24 of them fit into a standard size cardboard pallet and thence onto a standard wooden pallet

• 330 ml=33 cl 33 is the one of the degrees in this mason thing

• Most of the cans over the globe are sourced from Indonesia and most of the Indonesian companies have the standard can size as 330 ml hence coke and pepsi follows the 330 ml size for their cans as the different size create more cost

• That explains the dimensions. There is basically a lot of engineering that goes into the can's design. They found the optimum for the hand size and acceptable length, while maximizing the amount drink it can hold. They arrived at the current design. Also, manufacturability of the can made them choose a cylinder in the first place 

• The amount of aluminum used is at a point where the company who manufactures the cans is profiting the most.

• There was a standard 350 & 340 ml bottles used in some developed countries, however part of marketing strategy they reduced the size to 330ml and kept the price intact

• There was a shortage of Co2 in 1997 which translate to can size of 330 ml from the 355 ml

Now it up to you to select the most logical answer to our question, however sometimes going with the wind help us rather than questioning every marketing logics :)
