The typical size for a beer can is 350 ml, which is about 12 ounces. However, there are also smaller and larger beer cans available. For example, there are 250 ml and 500 ml beer cans. There are even larger beer cans that hold up to 1 liter of beer. If you want to bring a beer can with you when you go out, it's important to know the dimensions so that you can find one that will fit in your bag or backpack. And if you're looking to buy some new beers to drink at home, be sure to check the dimensions of the cans so that you know what will fit in your fridge.
