Birthday Balloons & Number Balloons

Large number balloons do the job of a whole wall of decorations: they say the age from across the room and photograph well from any angle. One number per display is plenty - two sets start to look like a shop window.

Air-filled displays hold their shape for days, so build them the night before. Read balloon arch ideas and how much helium you need before you buy anything else.

Hang a happy birthday banner first and build the balloons around it, then match your table confetti and cake topper to one balloon colour.

Honest note: we don't sell helium, bunting or arch kits - the balloon guide tells you where those fit.
