Place the zero end of the tape against one corner of the luggage, aligning it horizontally at the bottom.
3. Extend the Tape
Stretch the tape across the length of the luggage, keeping it straight and parallel to the bottom edge.
4. Note the Reading
Read the measurement at the point where the tape meets the opposite corner of the luggage case.
5. Consider the Handle and Wheels
For luggage with retractable handles or wheels, it’s crucial to include these in the measurement. Here’s a detailed guide:
| Type of Luggage | Measurement Considerations |
|---|---|
| Luggage with a Retractable Handle | Extend the handle to its fully extended length and measure from the bottom corner to the top of the handle. |
| Luggage with Wheels | With wheels extended, measure from the bottom corner of the case to the top of the highest wheel or axle. |
6. Record the Measurement
Note the linear inch measurement in your records for easy reference when selecting luggage that meets size restrictions.
Summing Up the Measurements
Once you’ve measured the length, width, and height of your luggage, it’s time to add them together. This will give you the total linear inches of your luggage. To do this, simply add the three measurements together. For example, if your luggage measures 22 inches long, 14 inches wide, and 9 inches high, the total linear inches would be 22 + 14 + 9 = 45 linear inches.
When summing up the measurements, it’s important to keep in mind that some airlines have different restrictions on the total linear inches of luggage that you can bring on board. For example, some airlines may allow a maximum of 45 linear inches, while others may allow 62 linear inches. It’s always best to check with your airline before you travel to make sure that your luggage meets their size requirements.
