Some shipping carriers restrict how big the box is used for shipping. For example, USPS allows a maximum combined length and girth of 108 inches.
To find out whether or not you exceeded that limit, follow these steps:
- Measure the three parcel dimensions in inches. See example below.
- 30″ = Length
- 10″ = Width
- 15″ = Height
- Add the two smallest dimensions and multiply by two. This is your package’s girth.
- Formula: [Value 1 + Value 2] x 2 = Girth
- Example: Our width and height are the smallest dimensions (10″ and 15″).
- Example calculations: [10″ + 15″] x 2 = 50″ (Girth)
- Take the longest dimension and add this to the girth. The result is the combined length and girth of your parcel.
- Formula: Value 3 + Girth = Combined Length + Girth
- Example: Our longest dimension is the length (30″).
- Example calculations: 30″ + 50″ = 80″ (Combined Length and Girth)
