Planning a wedding bar is one of those things that sounds simple until you are actually standing in a liquor store wondering how many cases of wine you need for 120 people who may or may not be heavy drinkers. Get it wrong and you either run out mid-reception or spend weeks returning cases of unopened Cabernet.
This page gives you everything in one place. Use the calculator to get exact quantities based on your guest count, event length, and bar type. Then download and print the three checklists below — one for supplies, one for day-of setup, and one to hand to your bartender.
How to Use the Wedding Bar Calculator
Start by entering your guest count and how long your reception will run. Five hours is the average for an American wedding reception including cocktail hour. Select your bar type — full open bar, beer and wine only, or wine or beer exclusively. Then adjust the percentage of guests you expect to be drinking based on your crowd.
The alcohol breakdown sliders let you fine-tune the split between wine, beer, and spirits. The standard starting point is 40% wine, 35% beer, and 25% spirits — but you know your crowd better than any formula does. A wedding with older family members often skews toward wine. A younger crowd at an afternoon celebration might lean heavily beer.
The calculator builds in a 15% buffer automatically, which most wedding bartenders recommend to avoid running out. It also includes champagne for the toast and an ice estimate — two things that catch people off guard every time.
The Three Wedding Bar Checklists
The calculator tells you what to buy. The checklists below tell you what to do with it.
The wedding bar supplies checklist covers everything from alcohol and mixers to glassware, garnishes, and bar equipment. Print it before your shopping trip so nothing gets forgotten.
The setup timeline checklist walks you through the night before, four hours out, and one hour out so the bar is ready before the first guests arrive.
The bartender checklist is designed to be handed directly to whoever is working your bar — a hired professional or a talented friend. It covers everything from setup through end-of-night inventory. You can download the free printable PDF version using the button below.

Quick Wedding Bar Reference Guide
How many drinks per person at a wedding? Plan for one drink per guest per hour as your baseline. Most receptions run 4–6 hours, putting the average total at 4–6 drinks per attending guest when you account for guests who drink more and guests who abstain entirely.
What is the most popular alcohol at weddings? Wine is the top choice at most American weddings, followed by beer and then spirits. A full open bar with a signature cocktail or two tends to feel the most celebratory and covers the most preferences.
Do you need a non-alcoholic option at a wedding bar? Absolutely. Plan for 20–30% of your beverage total to be non-alcoholic — still water, sparkling water, sodas, and ideally one mocktail option. Pregnant guests, designated drivers, and sober guests deserve to feel just as included.
