Medium fill balances comfort and structure. Mix bead sizes or add foam nuggets for plush support.
How to Use This Calculator
Measure the bean bag
Capture diameter (round), width/depth (square), or width/depth/length (lounger) at the widest points.
Choose a fill level
Pick soft for relaxed slouch, medium for everyday seating, or firm for structured gaming chairs.
Plan filler purchases
Use the recommended bead bags or foam weight to order supplies and keep a few spare bags for future top-ups.
Formula
Volume (cu ft) = Shape volume × Fill percentage
Bags needed = Volume ÷ 3 cu ft × (1 + Extra% ÷ 100)
Round bean bag volume ≈ π × r² × h ÷ 6. Square pouf volume = width × depth × height. Lounger volume ≈ π × a × b × length.
Frequently Asked Questions
How often should I top up a bean bag?
Add 5–10% new beads every 6–12 months depending on usage. Heavier use leads to faster settling.
Can I mix beads and foam?
Yes. A blend offers structure with a cushier feel. Start around 70% beads and 30% foam and adjust to preference.
What if the bean bag has a liner?
Measure the liner dimensions and fill it separately before inserting into the decorative cover.
Are eco-friendly fillers available?
Look for recycled EPS beads, plant-based beads, or natural buckwheat hulls—but adjust quantities because densities differ.
