How many cans of soda for 150 people at a wedding?

A good rule of thumb is to provide one can of soda per person, plus an extra 10%. So, for 150 people, you would need 165 cans of soda (150 x 1.1 = 165). You may, however, want to adjust this amount depending on the specific needs of your wedding guests. For example, if you are expecting a lot of children, you may want to have extra cans of soda on hand.
