Measured Packing Void Fill Mass calculator.
Subtract supplied occupied volume from measured container capacity and convert remaining space with your measured packing density.
Your inputs
Use measurements from your plan and properties from your chosen product. Any prefilled values are illustrative.

Formula and assumptions
How this calculation works.
Void volume = (inside width × inside length × inside height − occupied volume) × count; mass = void volume × supplied packing density. Does not establish cushioning, shipping protection or safe density for a product.
A worked example
Illustrative inputs only. Product properties and design dimensions are not recommendations for your project.
- Your measured in-place fill density
- 50 kg/m³
- Inside width
- 1 m
- Inside length
- 1 m
- Inside height
- 1 m
- Measured occupied volume per container
- 0.6 m³
- Identical containers
- 2
Packing fill mass: 40 kg
Use actual in-place density, not loose bag density. It does not guarantee protective performance.
Before you purchase
