Void Fill Estimator
Calculate the void space in your shipping box and compare void fill material costs.
Choosing the Right Void Fill Material
The best void fill depends on your product type, budget, and sustainability goals. Here's a quick guide:
Best for irregularly shaped items. Lightweight, good protection. Loose-fill peanuts are messy and harder to control. Use biodegradable corn-based peanuts where possible.
Excellent for fragile items — ceramics, glass, electronics. Provides cushioning and surface protection. Higher cost and less eco-friendly. Great for wrapping individual items.
Most sustainable option. Recyclable and compostable. Works well for non-fragile items. Paper fill machines can automate the process at scale. Good for DTC brands with eco positioning.
Lightweight and efficient. Low shipping weight impact. Easy to automate. Best for medium-fragility items. Not ideal for heavy items that can puncture pillows. Popular with high-volume fulfillment centers.
Volume estimates above assume you need to fill the full void space. In practice, you may need 10–20% more material than calculated to account for settlement and irregular placement. Always test with a drop test before scaling your packaging.
