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
