Shipping Weight Tips

  • Always round up: Carriers round up to the next pound or half-kilogram
  • Include packaging: Don't forget to add the weight of your box and packing materials
  • Dimensional weight: For large packages, dimensional weight may apply instead of actual weight
  • Use a scale: Kitchen or postal scales are more accurate than estimates
  • Verify at drop-off: Carriers will reweigh and may charge extra if weight is incorrect
