Things To Do For 18th Birthday Parties

So you’ve started planning an 18th birthday party. Before you get down to the details, it’s important to have a game plan. Kick off your party planning with the following tips.

  • If it’s not a surprise, ask what the guest of honor wants for a party. Take into consideration whether they want a smaller or larger party, or if they want to go out or stay in.
  • Come up with a special theme for the party based on what the honoree likes.
  • Plan your guest list. Make sure you have all the most important people to the birthday person included.
  • Send out your birthday invites early. Plan to send invites out three to five weeks in advance. If you send out invitations too late, some guests might not be able to make it. Also, make sure to include all the important information on the invites. This includes the who, what, when, where, and why of the party. For more details, check out our resource on what to include in party invitations or our guide on party invitation wording.
  • Gather all the needed party supplies and decorations. Decor makes or breaks a party, so make sure to put some thought in your choices.
  • Put the whole thing together. Get friends or family to help so that you can enjoy the party planning together.
  • Have fun, it’s a party after all!
