How We Calculate This

The calculator estimates balloon count from garland length and style, with a configurable spares allowance.

Balloons per metre

  • Single row: ~6 per metre
  • Double (standard): ~12 per metre
  • Organic / clustered: ~16 per metre
  • Full arch: ~14 per metre

Spares

Add 10-15% extra for popped balloons, duds and sizing rejects. Balloon quality varies - budget balloons may need a higher spares allowance.

Frame

Garland frame strip should be the garland length plus ~1 metre for tying off at each end.
