Carrier size comparison
Measure once and see every carrier at the same time. This checks your package against every service we hold size rules for and shows which accept it.
What this compares
Every service we hold size rules for, checked against the same package: the weight maximum, the length plus girth maximum, and, where a rule exists, the longest side. A dash means we hold no rule for that measurement on that service, which is reported rather than treated as a pass.
Worked example
A 12 × 10 × 8 in box weighing 100 lb.
- USPS refuses it: the general parcel maximum is 70 lb.
- UPS accepts it: its maximum is 150 lb.
- FedEx Ground accepts it; FedEx Ground Economy refuses it at 70 lb.
- One package, three carriers, and the deciding factor is a weight limit that varies by more than double.
Edge cases worth knowing
- Acceptance is not price. Every service that accepts your package may still charge very different amounts, because dimensional weight divisors differ.
- Services within a carrier differ as much as carriers do. FedEx Ground and Ground Economy are further apart than USPS and UPS on weight.
- These are domestic limits. International rules are not in our data.
Common questions
- Which carrier accepts the largest packages?
- Of the services we hold rules for, UPS domestic has the highest caps at 150 lb and 165 in of length plus girth. FedEx Ground matches it on size.
- Why do some rows show a dash?
- Because we hold no rule for that measurement on that service. We would rather tell you we did not check than imply it passed.
- Does this tell me which is cheapest?
- No. We do not quote prices. It tells you which will accept the package, which is the question you have to answer first.
