Balloon Arch Length Formula

Example 1: If the balloon arch is wider than it is tall: Height + Width = Approximate Total Length
Example 2: If the balloon arch height and width are about the same: 1.5(Height) + Width = Approximate Total Length
Example 3: If the balloon arch is taller than it is wide: 2(Height) + Width = Approximate Total Length

Note: Balloon quality may vary as much as 20% depending on how tightly the balloon clusters are packed.
