How many sodas for 20 people?

The number of sodas needed depends on the size of the sodas and the amount that each person will drink. Generally, a good rule of thumb is to provide one 12-ounce can of soda per person. If the sodas are larger or if you expect people to drink more than one soda, you may need to buy more. For example, if you are using 20-ounce bottles of soda, you will need to buy at least one per person and possibly more if people want seconds. To make sure you have enough, plan to buy at least 24 sodas if the party or gathering will be 20 people.
