Bean Bag Filling Calculator

What is a Bean Bag Filling Calculator?

A bean bag filling calculator helps you determine the exact amount of filler material you need to fill your bean bag. Whether you are making a DIY bean bag or refilling an old one, knowing the correct volume and weight of fillers ensures you get the right amount without overbuying.

Bean bags are popular furniture pieces filled with polystyrene beads or PVC granules. They are comfortable, lightweight, and affordable. However, figuring out how much filling to buy can be tricky since bean bags come in all shapes and sizes. This calculator takes the guesswork out of the process.

How to Calculate Bean Bag Fillings

The calculation is straightforward. First, measure the length, width, and height of your bean bag. Then use these formulas:

$$Volume = Length \times Width \times Height$$

$$Total\ Weight = Volume \times 20\ kg/m^3$$

The density of typical bean bag fillers is approximately 20 kg/m³. Once you know the total weight needed, divide by the bag size to find out how many bags to buy.

Step-by-Step Example

Let us say your bean bag measures 70 cm (length) x 60 cm (width) x 50 cm (height):

1. Volume = 0.7 m x 0.6 m x 0.5 m = 0.21 m³
2. Total weight = 0.21 m³ x 20 kg/m³ = 4.2 kg
3. With 1 kg bags, you need 5 bags (rounding up from 4.2)

This means you should buy 5 bags of 1 kg bean bag fillers. You will have a small amount of leftover filler for future use.

Tips for Choosing Bean Bag Fillers

• Polystyrene beads: The most common filler, lightweight and supportive.
• PVC granules: More durable and slightly heavier than polystyrene.
• Memory foam scraps: An eco-friendly option if you have access to them.
• Filler bag size: Buy multiple smaller bags rather than one large bag to make filling easier.
