Shipping providers such as USPS have certain restrictions when it comes to oversized packages. These may be incredibly costly to ship. This serves as an issue to the buyer and seller. If shipping costs are too high, it may deter the buyer from purchasing the item.
GearUp recommends that the length + girth for a package does not exceed 108 inches. USPS has a particular way of measuring length + girth. Any item exceeding 108 inches is extremely costly to ship.
Packages with length + girth above 130 inches cannot be shipped via USPS.
