Box size seems trivial — until it inflates your courier bill or lets your product rattle around and break. Getting it right saves money and reduces damage. Here's how to choose the right shipping box.
Why Box Size Matters
- Too big: wasted void fill, higher shipping cost, more movement and damage.
- Too small: crushed contents and burst seams.
- Just right: snug fit, minimal fill, lowest safe cost.
Understand Volumetric Weight
Couriers charge on whichever is higher: actual weight or volumetric (dimensional) weight. A common formula:
Length × Width × Height (cm) ÷ 5000 = volumetric weight (kg)
A big, light parcel can be billed by its size, not its weight. Smaller boxes often mean lower charges — check your courier's divisor.
How to Measure Correctly
- Measure the box's internal dimensions.
- Allow ~2–5 cm around the product for cushioning.
- Round up to standard box sizes you can reorder easily.
Match the Box to the Product
- Books/flat items: book wraps or slim boxes.
- Small products: compact cube boxes.
- Fragile/odd shapes: a size up, with extra cushioning.
Standardise Your Boxes
Stock 3–4 box sizes that cover most orders. It speeds up packing, simplifies reordering, and helps you predict shipping costs.
A Money-Saving Tip
Before finalising your packaging, run a few parcels through your courier's rate calculator at different box sizes. The savings across hundreds of orders add up fast.
