Learn the difference between star balloon weights and cube favour boxes. Find out which option keeps your helium balloons grounded and when to choose each.
Quick answer
Use a star balloon weight (165g) for large bouquets or outdoor setups, and a cube favour box (filled with treats) for small indoor displays or double-duty party favours.
Why the right weight matters
Helium balloons naturally float upward, so a weight that's too light won't hold them down. The key is matching the weight's mass and attachment method to the number and type of balloons you're using. Star weights provide a fixed 165g mass, while cube boxes rely on you adding filler—so their effective weight varies.
Star weight pros and cons
Star balloon weights are ready to use out of the box. The Black Star and Red Star models each hold up to 11 latex or 15 foil balloons, making them ideal for larger arrangements. Their decorative shape also adds a festive touch. The trade-off: they're single-purpose and can't double as a favour or gift.
Cube box pros and cons
Lilac Cube Balloon Weight/Favour Boxes are cardboard cubes that you assemble and fill with sweets, chocolates, or pebbles. This gives you control over the weight—light for a single balloon, heavier for a small bouquet. They also serve as party favours, saving you from buying separate items. The downside: they require assembly and won't hold as many balloons as a dedicated star weight.
Diagnosing which balloon weight you need
- Symptom: Your helium balloons keep floating away or tipping over lightweight objects.
- Likely cause: The object you're using to anchor the balloons is too light, or the attachment point is unstable.
- Corrective action: Choose a dedicated star balloon weight (165g) for bouquets of up to 11 latex or 15 foil balloons. For smaller displays or when you want a favour too, use a cube favour box filled with dense items like pebbles or wrapped sweets. Tie the ribbon securely around the handle or through the star's loop. If using a cube box, test the weight by adding filler until the balloon stays in place.
- When to stop or choose another option: If you have more than 15 foil balloons or the bouquet is outdoors in wind, a single star weight may not be enough. Consider combining two weights or using a heavier anchor like a sandbag. For a single latex balloon at a table centrepiece, a filled cube box is sufficient.
