Bean Bag Filling Calculator
Calculate the exact amount of filling material needed for your bean bag chair with accurate density calculations
Bean Bag Dimensions
The longest dimension of your bean bag
The width dimension of your bean bag
The height when filled
Weight of each package/bag you can buy
Filling Requirements
Calculation: Volume = 0 × 0 × 0 cm = 0.000 m³
Weight: 0.000 m³ × 20 kg/m³ = 0.0 kg
Packages: 0.0 kg ÷ 1 kg/bag = 0.0 bags
Recommendation: Buy 0 bags for complete filling
Example Calculation
Large Adult Bean Bag Example
Bean Bag Size: 90 × 70 × 60 cm (Large Adult)
Filler Type: Polystyrene Beads
Material Density: 20 kg/m³
Package Size: 1 kg per bag
Calculation Steps
Volume = 0.9m × 0.7m × 0.6m = 0.378 m³
Weight = 0.378 m³ × 20 kg/m³ = 7.56 kg
Bags needed = 7.56 kg ÷ 1 kg/bag = 7.56 bags
Result: 8 bags needed (rounded up)
Filler Material Guide
Polystyrene Beads
Most common, lightweight, affordable, good support
EPS Beads
Lighter than standard, good for large bean bags
Memory Foam
Premium comfort, excellent support, more expensive
Recycled Foam
Eco-friendly, good comfort, moderate pricing
Bean Bag Sizes
Tip: Bean bags compress over time. Buy 10-20% extra filling for future top-ups.
Understanding Bean Bag Filling Calculations
How Much Filling Do You Need?
The amount of filling required depends on three main factors: the size of your bean bag, the type of filling material, and how firm you want it to be. Our calculator uses precise density calculations to give you accurate measurements.
Why Density Matters
- •Different materials have different densities and comfort levels
- •Polystyrene beads are lightweight but provide good support
- •Memory foam is denser but offers superior comfort
- •Proper density ensures the bean bag maintains its shape
Calculation Formula
Weight = Volume × Density
- Volume: Length × Width × Height (in cubic meters)
- Density: Material density (kg/m³)
- Weight: Total filling needed (kg)
- Bags: Weight ÷ Package weight
Pro Tip: Bean bags lose volume over time. Consider buying 15-20% extra filling for refills.
