| 🎂 Balloon size | ⛽ Gas demand (helium) | ⏳ Flight time (approx.) | ⚖️ Load capacity (approx.) |
|---|---|---|---|
| 23 cm | 0.007 m³ | 3–4 hours | 0 g |
| 25 cm | 0.008 m³ | 4–5 hours | 0 g |
| 28 cm | 0.012 m³ | 5–8 hours | 2 g |
| 30 cm | 0.015 m³ | 6–12 hours | 2 g |
| 40 cm | 0.040 m³ | 24 hours | 20 g |
| 60 cm | 0.100 m³ | 36 hours | 90 g |
| 80 cm | 0.400 m³ | 48 hours | 220 g |
| 120 cm | 1,000 m³ | 72 hours | 880 g |
💡 Tip: Always plan for a little extra helium to compensate for fluctuations in temperature or air pressure.
👉 For large balloon bouquets or event decorations, we also recommend balloon weights to ensure the balloons stand upright and create fantastic photo opportunities.
