Considerations for Planning 18th Birthday Party Themes

When designing the perfect shindig, you have many creative 18th birthday party themes from which to choose. But regardless of which theme you go with, there are some general considerations that parents and new 18 year-olds should think about. You want everyone to have a good time, but you also want to be smart about planning and enjoying the festivities.

Guest list

When planning these 18th birthday party themes, you want to take some time to craft a well-planned guest list. Parents should work together with the teens on this task. Invite your friends but make sure the list doesn’t grow out of control. Though you want them to have fun, you must maintain a sense of order.

If you are holding the party at a venue, then you want to be sure that the location allows the number of guests you plan on bringing. To properly spread the message about the event, use a social media platform like Facebook to ensure all guests get the necessary info. 

​​​​Be relaxed but wary

As parents, you want to make sure that everyone at the party remains safe, while allowing the teens to enjoy themselves. Still, you don’t want to get so relaxed that things get out of control. During the party, be there in the background to ensure that everything goes off without a hitch and that nothing gets out of hand. Just don’t be so involved that you end up hampering your teen's time with their friends.

Document the event

The momentous occasion of turning 18 is a big milestone in anyone’s life. So make sure that the cameras are rolling. A key to enjoying any of these 18th birthday party themes is creating memories that you and your kids can revisit for years to come.

There are many ways you can go about documenting. As parents, you can go around the party and take pictures or video of the fun moments. You also have the option of hiring a professional photographer. Another fun idea is to buy a bunch of inexpensive disposable cameras and hand them out to the guests. Have them take their own pictures and then collect the cameras at the end of the event. Select the best shots and make a scrapbook out of them.

Many 18th Birthday Party Themes From Which to Choose

There are a million different 18th birthday party themes that you can choose for your big day. You can pick and choose from different ideas or create a brand new theme all your own. If you need assistance, below are a handful of themes to get you started.

Pool Party

Provided you have access to one, the pool party can be one of the easiest 18th birthday party themes to coordinate. Who doesn’t enjoy a dip in the pool? Even a minimalistic approach with lots of floats, lounge chairs, and tropical drinks will be a blast for all involved.

A fun group activity is watermelon polo. To play it, cover a watermelon in vegetable oil and drop it in the pool. Then have to teams battle while trying to get the slippery melon to the opposite side of the pool. It’s like soccer but played with your hands.

Toga Party

One of the wildest of the 18th birthday party themes is the infamous toga party. You know the deal. Everyone gets their favorite bed sheet and ties it up to look like the togas of ancient times.

For your decorations, you can take inspiration from pictures and movies based in the Greek era. Make your own handmade scrolls to act as invitations. Decorate the venue with columns, pedestals, and fake classical statue busts made out of paper mache.

Activities

On the invitations, invite guests to create the ultimate toga or Greek outfit and then have awards for best dressed. Instead of bobbing for apples, you and your guests can bob for grapes or olives. A great game to play at your toga party is Who Am I? To play, get a bunch of flashy headbands and write the name of a famous Greek character on each of them. Once everyone has their headband on, they have to guess who they are!

Bonfire

One of the most fun and relaxing 18th birthday party themes is the bonfire. Whether you can have the fire safely in your backyard -- or at another location such as the beach or a nature park -- there's just something about your best friends surrounding a crackling fire that just shouts celebration. To complete the bonfire look, make sure to gather lots of wood along with hot dogs and other food to roast on the fire.

Decorations

This is another of the 18th birthday party themes where you can add a little more texture to the event by setting up tiki torches. You can also hang string lights around the area. A thermos with a package of hot cocoa mix inside and bags of marshmallows make great party favors.

Dance Party

Dance party

Who doesn’t love a dance party? For those who love to get down, this is one the most engaging 18th birthday party themes you can have. When planning to have a dance party, get a feeler for which of your guests love to dance and those who are less comfortable doing so. You want to make sure you include everyone. When you get that all set, get ready to boogie!

Decorations

Either find a venue to hold your dance party or create your own dance floor at home. In either case, make sure there is enough room for all of your guests to get wild. Naturally, you will want to hang a disco ball above the dance floor. If you are having the dance party at home, you can decorate with cartoonish musical notes and records. To make them, get some black construction paper and cut out the shapes before hanging them on the wall. Finally, blow up a healthy amount of balloons and put them on the dance floor so the guests can dance around them.

Activities

Of course, one of the most engaging activities at a dance party is dancing. You can mix things up with some dance related games. Start by having a dance contest with fun awards for the winners. For another fun competition, have everyone sit in a circle. The first guest stands up and does a dance move. Then the next person goes up repeats that dance move and then adds one of their own. Add to the new dance routine with each new guest. Anyone who forgets a move is out. Play until one dancer remains.

Another fun activity is setting up a styling area where guests can have their hair sprayed with glitter or get neon highlights in their air.

Cocktail Party
