Package Girth Calculator
Calculate girth and length-plus-girth for shipping
Frequently Asked Questions
Girth = 2 × (width + height). It measures the distance around the two shorter sides of the package (perpendicular to its length), the same way you'd measure around a box with a tape measure.
Length + Girth = the package's length plus its girth. Carriers like USPS, UPS, and FedEx use this combined figure to define 'oversize' packages — exceeding a carrier's length-plus-girth threshold (commonly 130 inches for UPS/FedEx ground, or 108 inches for USPS Priority/Ground Advantage) triggers additional oversize shipping charges.
Length is the longest side of the package. Width and height are the two shorter sides used to calculate girth.
No — thresholds vary by carrier and service level, and change periodically. Check your specific carrier's current published dimensional and oversize rules before shipping a large package.
