Number Balloons: Sizes, Colours & Styling Ideas

Foil number balloons are the fastest way to mark an age or a year. Here's how to choose and style them.

Sizes

• 16" (40cm): the standard — great on a stick, in a bunch, or as part of a garland.
• Giant 34" (86cm): statement pieces for milestone birthdays and photo backdrops.

Helium or air-filled?

• Helium lets them float — foil numbers hold helium for days. Great for a floating "30" over the table.
• Air-filled (on a stick or attached to a wall/garland) lasts indefinitely and is perfect for backdrops. Giant 34" numbers look stunning either way.

Colours

Gold, silver, rose gold, black, blue, pink and more — pick a colour to match your theme, then coordinate with letter balloons and latex.

Styling ideas

• Age or year: combine digits — "18", "50", or "2026" for graduations and NYE.
• Garland focal point: anchor a balloon garland with a giant number.
• Cake table: a pair of 16" numbers either side of the cake.
• Add weights, sticks & cups to display them.
