What dimension qualifies a parcel as oversized in Postal Service terms?

A parcel is classified as oversized by the Postal Service if its combined measurement of length and girth exceeds specific thresholds. In postal terms, length is determined as the longest side of the package, while girth is calculated by applying the formula: girth = (2 x width) + (2 x height).

The threshold for a parcel to qualify as oversized starts at 108 inches and goes up to less than 130 inches when adding length and girth together. Therefore, if the total measurement of length plus girth falls within this range, it is considered oversized. This classification is important as it can affect shipping costs and service options.

The incorrect options either set the measurement threshold too low or too high or are based on incorrect dimensional calculations. The combination specified in the correct answer accurately reflects the Postal Service’s definition of an oversized parcel, adhering to their guidelines for parcel dimensions.
