What Are Linear Inches?

The entire size of a bag is normally measured in linear inches, which is a measurement that is commonly used by airlines. Particularly it considers the bag’s length, width, and height, which are the three dimensions of the luggage.

A simple addition of these three measures is all that is required to get the linear inches that a bag or luggage has. For example, if a bag has a length of 22 inches, a width of 14 inches, and a height of 9 inches, then the linear inches on the bag would be 45.

How To Figure Out Linear Inches For Luggage

Calculating linear inches is a straightforward process. Here’s a step-by-step guide to help you measure your luggage correctly:

Step 1: Get the actual dimensions

First, you need to find out how big your bag is. Most luggage makers list the sizes in the description of the item. Even if you don’t know these things, you can still use a tape measure or ruler to find out how long, wide, and tall your bag is.

Step 2: Add the Dimensions

Next, take your bag’s length, width, and height and add them up. Say your bag is 28 inches long, 19 inches wide, and 11 inches high. To find its length, you would add the width and height together.  28 + 19 + 11 will give you 58 linear inches.

Step 3: Check against Airline Restrictions

Now that you have calculated the linear inches of your bag, compare it to the airline’s size restrictions. Most airlines have specific limits for both carry-on and checked luggage.

For most flights in the US, the largest bag that can be checked is 62 linear inches long. But different airlines may have different rules, so it’s important to check the rules for the company you want to fly with.
