In cans of soda and beer…why has this become the determined serving of said beverage?

I am not a can authority…

But have you noticed that the standard 12 ounce can fits very neatly into an average person’s hand?

This is very US-centric. When I have traveled abroad I have found that the cans are smaller (I don’t remember the standard size in Europe, maybe something like 0.3 L which is 10 fl. oz.). I don’t think the average European hand is any smaller 😉

Yup…typical American over indulgence.  
Fatties with their extra 2 oz. and all…hmph  
😉

Yeah, I think a Big Gulp in Europe is only 28 oz. 😉

It needed to be 12oz. to fill up the cans and bottles they were making.😃

When Coca-Cola first introduced their bottles they were the 6 oz. size. In the 50’s (?) Pepsi introduced 12 oz. bottles as a marketing ploy.

_Pepsi-Cola hits the spot.  
Twelve full ounces that’s a lot.  
Twice as much for a nickel too.  
Pepsi-Cola is the drink for you._

Before long, virtually all bottlers used the 12 oz. standard. When cans came along this was a natural migration. It wasn’t until later that larger size bottles (16 oz., 20 oz. 1 liter, 2 liter, etc.) came into use.

Well, if it was 11oz, you’d be asking “Why 11oz?”. Why 12? Why not 12?
