How Much Soda for a Party?

Soda Planning Guide

Soda is sold in two formats that suit different group sizes. A 2-liter bottle pours about ten 8-ounce servings, while a 12-can case gives you twelve single-serve portions that cover roughly six to twelve people depending on how much else is being drunk. Plan about two sodas per guest over an event. For a large party the 2-liter bottles are clearly cheaper per ounce, but cans waste nothing, stay fizzy, and travel better, so a mix of both, bottles for the main pour and cans for grab-and-go, usually serves a crowd best.

Variety matters more than total volume, because one flavor never satisfies a mixed group. Stock at least three options across the obvious categories: a cola, a lemon-lime, and a ginger ale or root beer, and always include a diet or zero-sugar choice, since a meaningful share of guests will only drink that. Ginger ale and lemon-lime double as cocktail mixers, so they tend to run down faster than you expect at a party where people are also drinking alcohol. Buy a little extra of those two specifically.

Soda needs to be cold and it needs ice, which is the part hosts most often under-buy. Beyond serving it chilled, plan about one pound of ice per guest just for cups and coolers, separate from any ice cooling the bottles. Set the 2-liters out cold and keep cans on ice in a cooler so guests can help themselves. If the soda is also doing double duty as a mixer, keep a dedicated stash of lemon-lime and club soda back so the cocktail station does not drain the supply meant for non-drinkers.
