20 Best Birthday Party Decorations for Kids

Tomtops may earn a commission from the links in this guide. Learn more or read how we pick.

The 9ft pre-strung Happy Birthday banner is the most useful of these birthday party decorations for kids, because it arrives ready to hang and it is reusable, which almost nothing else here is. The number that catches people out is piece count: a 210 piece kit is mostly balloons you inflate yourself. The table below separates what you hang from what you build.

A good birthday party doesn’t need to be complicated – it needs to look like someone put in real effort. The right decorations do most of the heavy lifting: a balloon arch at the entrance, a banner across the wall, a few coordinated table pieces. Kids notice color, scale, and sparkle before anything else, so the goal is visual impact without spending half the day setting up.

We picked these 20 decorations based on Amazon review counts, overall ratings, and variety across styles and age ranges. Whether you’re throwing a rainbow party for a five-year-old or a dinosaur bash for a nine-year-old, there’s something here that fits. Every item is practical, well-reviewed, and available for fast shipping.

Mix and match freely – many of these are designed as kits, so one purchase covers several decoration needs at once. We’ve noted key specs and age suitability in each description to help you build a setup that works for your space and your kid.

Birthday party decorations for kids compared by size and assembly

How we picked: we chose birthday party decorations for kids in stock on Amazon with strong review counts, then recorded the piece count, physical size and how much assembly each one needs from its listing. Assembly time is the thing parents underestimate most, so we have separated hang and done items from balloon kits you inflate by hand. We did not test these products ourselves.

How to read the assembly column

A balloon garland kit advertised at 106 or 132 pieces is counting individual balloons, and every one of them is inflated by hand before it is taped into an arch. Budget an hour or more for those, and ideally the evening before.

Backdrops, banners and tinsel garlands hang in minutes, and tableware sets need only unpacking. Foil number balloons sit in between, since they need helium or a pump that is not usually included.

#1 · BALLOON GARLAND

Pink Balloon Arch Kit with Foil Butterfly Balloons

A complete pink and butterfly-themed party setup in one box. The arch strip, confetti balloons, and foil butterfly balloons coordinate cleanly, and the included backdrop doubles as a photo wall.

Pros

• ✓106 pieces cover a doorway or table edge
• ✓Foil butterflies break up plain latex
• ✓Pink and rose gold suits several themes

Cons

• ✗Every balloon is inflated by hand

• ✓Arrives pre-strung, so it is hang and done

Pros

• ✓17 pieces of honeycombs and swirls
• ✓Pastel palette works for any age

Birthday party decorations for kids: your questions answered

How to decorate for a kids birthday party?

With birthday party decorations for kids, work from the largest surface inward, because a big backdrop does more visually than scattered small pieces. So hang a fabric backdrop like the dinosaur or solar system panel first, then add a pre-strung banner. After that, build a balloon garland around the edges if you have time. Finish with tableware and a number balloon at the cake table, since that is where the photographs get taken.

Where can I buy party decorations for kids?

Amazon carries the widest range of themed kits and is where all twenty picks here come from, while Party City, Oriental Trading and Hobby Lobby cover the same ground in store. The advantage of buying birthday party decorations for kids online is that listings publish piece counts and dimensions, so you can check what you are actually getting. The disadvantage is that you cannot judge quality by eye, which is where review counts help.

Where can I buy decoration items for a birthday party?

Beyond the general retailers, decide whether you want single use or reusable items, because that changes where to shop. Tableware sets and tablecloths are disposable by nature, whereas fabric backdrops, photo props and pre-strung banners survive several parties. Buying one good reusable backdrop and cheap themed tableware around it usually costs less across a few birthdays.

What’s the latest party decoration trend?

Among birthday party decorations for kids, balloon garland arches remain the dominant look, and the bow and checkered print in the pink balloon set is the current variation on it. Muted and sage palettes, like the safari jungle kit, have largely replaced primary colours for younger children. Milestone photo banners for first birthdays have also become standard, and unlike most decorations they are kept afterwards.

How long do birthday party decorations for kids take to put up?

It depends entirely on which type you buy, and this is the part worth planning ahead. Backdrops, banners and tinsel garlands go up in ten to fifteen minutes, and tableware needs only unpacking. A balloon garland kit of 106 or 132 pieces realistically takes an hour or more because every balloon is inflated by hand, so build it the evening before rather than on the morning.

How many decorations do I need for a kids party?

So match tableware to your guest count, and treat everything else as staging. The mermaid set serves 25 and the unicorn set 24, which covers most children’s parties, while the cactus set at 144 pieces suits a smaller group. For decoration itself, one backdrop, one banner and one garland is usually enough for a single room, and adding more rarely improves the photographs.

Are balloon arch kits worth it?

Balloon arches photograph better than anything else here, but they cost the most effort by a wide margin, so the answer depends on your time rather than your budget. A 132 piece kit gives a full arch for the price of a few foil balloons, but you will spend an evening inflating and taping it. If time is tight, a fabric backdrop with a tinsel garland gets you most of the visual impact in fifteen minutes.

A safety note on latex balloons

Five of these picks are latex balloon kits, so this is worth stating plainly. Latex balloons carry a federally mandated warning under CPSC labelling rules, because children under eight can choke or suffocate on uninflated or broken pieces. The latex conforms to the airway, so back slaps and abdominal thrusts often fail. Keep uninflated balloons away from young children, and clear away any that pop straight away. Foil balloons, like the number and chicken sets here, are not covered by that warning.

How to choose birthday party decorations for kids

Read the piece count as a warning, not a promise

Piece count is the number to read carefully in birthday party decorations for kids, because a high count usually means balloons rather than value, so treat it as a measure of work ahead. Tableware sets count plates and napkins, which genuinely serve a guest list, whereas garland kits count individual balloons you must inflate. Check which of the two you are buying before assuming a big number is generous.

Buy one reusable anchor piece for future birthdays

Most birthday party decorations for kids are thrown away the same evening, so a single item that survives changes the economics. A fabric backdrop, a pre-strung banner or a set of photo props all come out again next year, while tableware and latex balloons will not. Spend where the reuse is and economise on the disposable layer around it.

Decorate the cake table before the rest of the room

Nearly every photograph from a children’s party is taken at the cake, so that corner earns the most attention.

A number balloon, a backdrop behind it and a candle do more for the pictures than decorating four walls. Then spread whatever is left over the rest of the room rather than starting there.
