Struggling to figure out how much bean bag filling you need? Our Bean Bag Filling Calculator takes the guesswork out of it! Whether you're refilling an old bean bag or making a new one, this tool helps you accurately determine the required volume of polystyrene beads, shredded foam, or other fillers. Stop wasting money on too much or too little fill.
Formula:
For Rectangular/Square Bean Bags: Volume (ft³) = Length (ft) × Width (ft) × Height (ft) × (Desired Fullness / 100)
For Round/Spherical Bean Bags: Volume (ft³) ≈ (4/3) × π × (Radius (ft))³ × (Desired Fullness / 100)
Where:
- `L`: Length of bean bag
- `W`: Width of bean bag
- `H`: Height of bean bag
- `D`: Diameter of bean bag (for round, Radius = D/2)
- `Fullness`: Desired fullness percentage (e.g., 80)
- `π`: Pi (≈ 3.14159)
