How to Plan a Birthday Party: A Step-by-Step Checklist

Most birthday parties do not go wrong on the big things. They go wrong because ten small decisions get made in the wrong order: invitations go out before the date is firm, the cake is ordered before anyone knows the headcount, and the chairs are an afterthought the morning of. A good checklist puts the decisions in sequence so each one makes the next easier.

Decide four things before anything else

Every other choice depends on these, so settle them first, even if you change them later.

The budget. Write down a total number you are comfortable spending, then divide it up. Food and drink usually take the biggest share, followed by the venue or rentals, then cake and decor, then entertainment. Hold back a small cushion for things you did not think of. Our event budget spreadsheet does the math for you.

The guest list. Count the people you must invite, then the people you want to invite, then decide where the line falls. A common rule is that a share of invited guests will not make it, but do not count on that for close family or for parties with a sit-down meal.

The date and time. Check school calendars, long weekends, big sports games and any holiday that weekend. Chicago-area weekends fill up fast in May, June and December.

The style. Sit-down dinner, open house, backyard cookout, or activity party? The style decides how many seats, tables and plates you need. See how many chairs you need for the seat math by style.

A six-week timeline you can copy

Six weeks is a relaxed schedule. If you have less time, compress the early steps and keep the order the same.

Six weeks out: set the budget, guest count and date. Reserve the venue, park pavilion or your own yard plan. Start the guest list in a spreadsheet or the guest list and RSVP tracker.

Four weeks out: choose the theme or color palette, pick a caterer or decide the menu, and send save-the-dates if guests need to travel.

Three weeks out: send invitations with an RSVP date about ten days before the party. Order the cake. Request a quote for rentals.

Two weeks out: confirm the menu, order decor and party favors, and book any entertainment such as a DJ, face painter or photo booth.

One week out: chase RSVPs, finalize the headcount, make a shopping list, and write the day-of timeline.

The day before: pick up ice and non-perishables, set up what you can, charge speakers and cameras, and check the forecast.

Rough planning numbers by guest count

These are typical starting points. A sit-down meal needs a seat for every guest, so use the higher chair count in that case. For more on dishes, see how many plates per guest.

Pick the right space for the party

A home works well for up to about 20 guests if you have room to move. Past that, think about a backyard with a tent, a park pavilion, a community room or a restaurant private room. Ask each venue what is included, such as tables, chairs, kitchen access and cleanup, before you decide. Our guide to questions to ask a venue about rentals is a good list to bring.

If you are hosting outdoors, plan for weather from the start. A tent or canopy over the food and main seating area saves the day when a storm rolls in. Rain plan with a tent explains how to decide.

Food, cake and drinks without over-buying

Plan food by the length of the party. A two-hour party with cake needs light snacks. A party that runs through a meal time needs real food. Our how much food per person guide covers amounts for appetizers, mains and desserts. For drinks, think about one to two drinks per guest per hour for the first couple of hours, and keep water out for everyone.

Build the day-of plan

A short written timeline keeps a party calm. Note when helpers arrive, when food goes out, when the cake is cut and when you plan to wrap up. Hand it to one trusted friend so you are not the only person who knows the plan. The run of show template is a one-page format for this.

What people forget

Birthday parties often miss the small logistics: a place for coats and gifts, a trash and recycling plan, a first-aid kit, extension cords, ice, a lighter for the candles, serving utensils, and a plan for leftovers. Put these on your list in week one.

Order of operations

Chicago-area notes

Chicago weather changes quickly, especially in spring and fall, so have a plan B for any outdoor party. Many park districts and forest preserves in Cook, DuPage, Lake and Will counties rent pavilions, and popular dates book months ahead, so check with your own park district for rules on tents, bounce houses, alcohol and amplified sound. If you live in a condo or high-rise, ask your building about the party room, deposit and any rules for deliveries or the freight elevator. In city neighborhoods with limited parking, tell neighbors ahead of time and leave a clear spot for delivery trucks. Read our Chicago park district event permit guide before you plan a larger party in a public space.
