FedEx Length + Girth Calculator
FedEx size limits
FedEx enforces thresholds that affect what you pay and whether your package ships. The calculator above flags each one automatically.
- Up to 130 inches: Standard rates.
- 130 – 165 inches: Between 130 and 165 inches, FedEx applies an Oversize Charge on top of the base rate.
- Over 165 inches: Over 165 inches, FedEx Ground does not accept the package — use FedEx Custom Critical or alternative freight.
Maximum single side: 108 in. Maximum weight: 150 lb. Always verify against the current FedEx rate guide before shipping high-value items.
How FedEx measures girth
FedEx uses the standard girth formula:
girth = 2 × (width + height)
length + girth = length + 2 × (width + height)
Worked example. A 50 × 20 × 20 inch box has girth (20 + 20) × 2 = 80 inches, and length + girth = 130 inches.
For tubes or cylindrical packages, FedEx uses circumference at the widest point. Girth = π × diameter for a perfect cylinder.
