A light but bulky package occupies space in a courier vehicle. A 30 × 20 × 15 cm box has a 5000-divisor weight of 1.8 kg even if its scale weight is only 0.8 kg. Use the larger value, then the service slab. Improve packing fit before comparing prices, while preserving enough cushioning.
01How should I measure parcel dimensions?
Measure the outside length, breadth and height of the sealed package in centimetres, including bulges. Use the widest points, not the product’s inner dimensions. For a soft mailer, measure after packing and sealing. Keep the measuring tape visible in photographs if you may need evidence later.
02What is volumetric weight?
Volumetric weight accounts for the space a parcel occupies. With a divisor of 5000, a 30 × 20 × 15 cm box has a volumetric weight of 1.8 kg. The courier generally bills the higher of actual and volumetric weight, then applies its weight slab. Confirm the divisor for your selected service.
03Why does a small weight change affect the price?
Couriers sell weight in slabs rather than charging every gram separately. A parcel just above a slab boundary can move into the next slab. Compare the quote using final chargeable weight and the selected service’s base and additional-weight rules. Never reduce the declared weight to force a cheaper result.
04How do I choose the right box size?
Choose the smallest sturdy box that still leaves room for proper cushioning. Wrap the product, fill empty space and gently shake the sealed parcel; the contents should not move freely. A large empty box can raise volumetric charges, while a tight box can transfer impacts directly to the product.
05Which packing photographs should I keep?
Keep clear photos of the product, cushioning, sealed outer box, label, scale reading and each dimension with a measuring tape. Match the evidence to the order or AWB and keep original files. This makes a weight or damage review easier, but does not override the courier’s claim terms or deadlines.
Before your next shipment
- Measure the sealed pack in centimetres.
- Confirm divisor and slab for the service.
- Compare two suitable box sizes in the tool.
Examples are for planning. Your selected courier, booking quote and applicable policy determine the actual service and charges.
