International Shipping Cost Comparator
Enter your package's weight and dimensions and the destination country to compare estimated cost across carriers, using whichever is higher: actual weight or dimensional (volumetric) weight.
Why this matters
Dimensional weight pricing catches a lot of sellers off guard: you weigh a package, expect a certain shipping cost, and then get billed for a much heavier "dimensional" weight instead because the box is bulky relative to how light it is. Comparing several carriers side by side — each with a different dimensional-weight divisor — makes it easier to see which one actually treats your package size favorably, before you commit to one.

How to use it
- Weigh your package on a scale — enter that as the actual weight.
- Measure its length, width, and height (the box, not the item inside).
- Enter the destination country and compare the carriers listed — they're sorted from cheapest to most expensive for your package.
Example scenarios
These illustrate how the comparison works, using this tool's example data — not real quotes.
- A dense item like a phone case (0.3 kg, 15x10x3 cm) is small enough that its actual weight is what gets billed — dimensional weight barely factors in.
- A bulky-but-light item like a lampshade (0.8 kg, 40x40x40 cm) can end up billed at several kilograms of dimensional weight instead of its real 0.8 kg, because the box is large relative to how little it weighs.

Frequently asked questions
What is dimensional (volumetric) weight?
Carriers charge based on whichever is higher: the actual weight of your package, or a weight calculated from its size (length x width x height, divided by a carrier-specific factor). A large, light box — like a lampshade or a stack of foam packaging — can cost more to ship than its scale weight suggests because of this.
Why do different carriers show different costs for the same package?
Each carrier sets its own per-kg rate, base fee, and dimensional-weight divisor. A carrier with a larger divisor is more forgiving of bulky-but-light packages; one with a smaller divisor charges more for the same box.
Is this real, current carrier pricing?
No — see the disclaimer above. The carrier names and rates here are illustrative placeholders, not a live quote from any real shipping company. Use this to understand how dimensional weight affects cost, not to book a shipment.
What if my destination country isn't specifically supported?
Countries not explicitly mapped fall into a general "other" rate zone rather than failing outright, so you'll still get a comparison — just a less region-specific one.
