Birthday Party Supplies & Decorations

Plan the birthday around the guest of honour, the room and the number of people coming. This collection brings together birthday party supplies, decorations, balloons and table details for children, teens and adults.

Shop birthday supplies by the job they need to do

Start with birthday tableware for the guest count. Choose one focal area for a birthday balloon, garland or backdrop, then add party favours once the final headcount is clear.

Choose a birthday theme they already love

Character collections make the first decision easy. Shop Bluey, PAW Patrol, Pokémon, Hello Kitty, Lilo & Stitch or Harry Potter, then use matching plain colours to finish the room without repeating the same character on every surface.

Make a plan before filling the cart

Our birthday party planning guide includes a timeline, supply quantities and a room-by-room checklist. For activities, compare birthday games by age, indoor games for small spaces and outdoor backyard games.

Plan it beautifully

Plan the birthday around the people and the room

A backyard party for twelve needs a different setup from a living-room party for six. Set the guest count and the main activity first. The theme, table and decorations become much easier to choose after that.

01

Set the guest count

Count children and adults separately. That gives you a better tableware total and helps you choose games that fit the group.

02

Choose one focal area

Use the cake table, entrance or photo spot for the strongest decorations. The rest of the room only needs a few repeated colours.

03

Keep the schedule loose

Plan one main activity, food and cake. Leave a little open time so late arrivals or an enthusiastic game do not upset the afternoon.

Collection guideBirthday Party Supplies & Decorations

Plan the birthday around the guest of honour, the room and the number of people coming. This collection brings together birthday party supplies, decorations, balloons and table details for children, teens and adults.

Shop birthday supplies by the job they need to do

Start with birthday tableware for the guest count. Choose one focal area for a birthday balloon, garland or backdrop, then add party favours once the final headcount is clear.

Choose a birthday theme they already love

Character collections make the first decision easy. Shop Bluey, PAW Patrol, Pokémon, Hello Kitty, Lilo & Stitch or Harry Potter, then use matching plain colours to finish the room without repeating the same character on every surface.

Make a plan before filling the cart

Our birthday party planning guide includes a timeline, supply quantities and a room-by-room checklist. For activities, compare birthday games by age, indoor games for small spaces and outdoor backyard games.

Shop by theme

Find a theme that fits the party.

Choose the main idea, then compare balloons, decorations and table pieces that work with it.

Helpful answers

Planning birthday party supplies & decorations

What birthday party supplies should I buy first?

Start with tableware for the guest count and one decoration for the cake table, entrance or photo area. Add balloons and smaller details after the main colours and theme are settled.

How much tableware should I order?

Plan one plate and cup per guest, plus a small buffer for dropped plates, seconds and late additions. Separate dessert plates are useful when cake is served well after the main food.

How early should I order birthday decorations?

Order once the date, venue and guest count are firm. Earlier is better for character themes, larger quantities and anything needed for a specific setup plan.

Can I mix character products with plain decorations?

Yes. One or two character pieces can anchor the theme. Plain balloons, tableware and decorations in matching colours keep the room coordinated without covering every surface with the same design.

Ready when you are

Make the celebration feel like yours.
