Insert and cavity size calculator
Insert outer size and cut-out size for a product cavity.
How it works
Insert outer size = product + border on each side. Cavity = product + fit allowance.
Tip
Leave a finger notch on one side so the product can be lifted out.
Questions
Foam or card insert?
Foam cushions fragile items; card and moulded pulp look premium and are paper-based.
How deep should a cavity be?
Deep enough to hold the product at about half its height, or fully for fragile items.
