Quick Answer: Drinks You Need for a Party
According to Party Genius's drink calculator data, for a party of 20 people lasting 2 hours, plan for 20 water bottles, 24 juice boxes (for kids), 48 cans of soda, and optionally 16 beers or glasses of wine for adults. Budget $30–60 for non-alcoholic drinks. Last reviewed May 18, 2026.

The Party Drink Calculator computes water, juice, soda, and (optionally) alcoholic drinks based on guest count, kid/adult split, party duration, and weather. The formulas: 0.5 water bottles per person per hour, 2 juice boxes per kid (flat), 1 soda can per kid per hour, 1.5 cans per adult per hour, and 1 alcoholic drink per adult per hour for the first 2 hours (0.5 per hour after). Hot-weather outdoor parties get a 1.3× multiplier across the board. Take a 3-hour mixed party with 30 guests — 18 kids, 12 adults. That resolves to 45 water bottles, 36 juice boxes, and 108 soda cans, plus ~30 servings of beer or wine if alcohol is on. The output includes cost ranges, exact quantities, and a printable shopping list.
Table A — Drinks for a Party by Guest Count
Quick reference table for common party sizes. Based on a 2-hour indoor party, 60% kids / 40% adults split, non-alcoholic drinks only. Numbers derived from Party Genius's calculator constants. The calculator above adjusts for duration, weather, and alcohol.
Table B — Drink Mix by Audience (per 100 drinks)
Industry-standard hosting guidance for splitting your drink budget across water, soda, juice, and adult beverages. Adjust upward on water (always) and downward on adult beverages for daytime or family-heavy events.
Table C — Soda Pack Equivalents
Translate the number of drinks you need into store-buyable units. A standard 12-oz can serves one person; a 2-liter bottle serves about 6 cups (~67 oz total). Cases typically hold 24 cans.
Table D — Ice Quantity by Guest Count
Industry-standard baseline of 1 lb of ice per guest, split roughly 40% for drink cups and 60% for cooling bottles, cans, and food in coolers. In hot weather or for 4+ hour parties, bump to 1.5 lbs per guest.
Table E — Cases & 2-Liters of Soda by Guest Count
How many cases and 2-liter bottles of soda to buy, by guest count — based on a 2-hour party with soda as the main drink (60% kids / 40% adults). A 24-pack case holds 24 cans; one 2-liter pours about 6 cups. Serving alcohol or a shorter party? The soda calculator adjusts for your exact party.
Table F — Bar Stocking: Bottles of Liquor, Wine & Beer by Adult Count
The calculator gives you a drink count. The liquor store sells bottles. This table converts one into the other for a 3-hour adults-only party, using the US standard drink — 1.5 oz of spirits, 5 oz of wine, or one 12-oz beer. A 750 ml bottle of spirits pours 16 drinks, a 1.75 L handle pours 39, and a 750 ml bottle of wine gives 5 glasses.
Read each bottle column as “if this were the only thing you served.” Nobody stocks a bar that way. Pick two or three categories and split the drink total between them — 20 adults needing 50 drinks might be 2 cases of beer, 4 bottles of wine, and 1 bottle of spirits, not 3 cases plus 10 bottles plus 4. Buy one extra bottle of whatever your crowd actually drinks and skip the rest; unopened bottles keep, and most stores take back sealed cases. Serving spirits means you need roughly twice the ice a beer-and-wine party needs, plus mixers — count those with the soda calculator.
The same guest count that sets these drink numbers also tells you how much ice to buy and how much food to serve — drinks, ice, and food all scale off the same headcount, and it decides how much room you need. The party venue size calculator turns your headcount into floor space, table count, and where the drink station goes. New to terms like cocktail ice versus cooler ice? The party planning glossary defines them, and our party planning guides cover the rest of hosting — RSVPs, timing, and drop-off rules.
Pro Tip
The #1 drink mistake? Not enough water. Kids run around for 2 hours and parents forget water isn't exciting but it's essential. Buy 1.5x more water than the calculator suggests if it's an outdoor summer party. And always have a cooler — warm juice boxes are a crime against childhood.
