How to measure your package
- Weight: weigh the packed box, including the item, padding and box. Round up to the next ounce.
- Size: measure the outside of the box, longest side as length.
- Big but light boxes can cost more than their weight suggests, because carriers charge by size above certain dimensions.
Price shipping into your listing
Add the label cost to what buyers pay, or build it into the price if you offer free shipping. Then run the numbers in the eBay fee calculator, and check what the item sells for.
