What Are Linear Inches?

Linear inches is a measure of length that combines the height, width, and depth (length) of your bag or suitcase. To calculate it, you’ll need to add together each dimension in inches — for example, if a suitcase measures 14″x 9″ x 22″, your linear measurement would be 45″.

Bear in mind that this sum includes any external pockets or accessories on your bag. And don’t forget to factor in any wheels and handles when you’re measuring too.

Once you’ve determined the linear measurements of your luggage, check with your airline to find out what their size restrictions are for checked bags and carry-on items. You may also have to pay an additional fee if your bag exceeds the size limit.

Common Airlines that use linear inches to calculate luggage size:

  • Air Canada – 62 linear inches for checked luggage
  • American Airlines – 62 linear inches for checked luggage
  • Delta – 62 linear inches for checked luggage, 45 linear inches for cabin luggage
  • Southwest Airlines – 62 linear inches for checked luggage

Do Linear Inches Include Wheels?

Yes, the linear inches should include any wheels or handles on your bag — so be sure to factor them in when you’re calculating.

The same rules apply to items like golf bags and skis, which are decided by their total length when added together with their accompanying accessories.

How Many Linear Inches Are in a Foot?

There are 12 linear inches in a foot, and one foot is equivalent to 30.48 centimeters (cm).

So if you have items that measure more than one foot, you can add them together in inches or convert the measurements into feet and then calculate the linear inches for your bag.

Linear Inches to Centimeter (cm)

A linear inch is equivalent to 2.54 centimeters (cm). To convert your measurements into centimeters, simply multiply the number of inches by 2.54. For example, if your bag measures 15 linear inches, it is equal to 38.1 cm when converted into cm.


Linear inches can seem confusing at first, but they’re actually an easy way to measure the size of your luggage before traveling. Just remember to add up all the dimensions — including external pockets, wheels, and handles — to find out what your linear measurement is. And remember to check with your airline oversize restrictions too. Armed with this knowledge, you’ll be ready for a worry-free getaway.

Linear dimensions are used to measure the length, width, and height of objects in various formats or units. They provide a precise way for determining size and locations by using points that lay along straight lines. Linear dimensioning is an essential tool for many professions, particularly those in manufacturing, engineering, construction, and architecture.

For instance, linear dimensioning allows engineers to accurately map out designs for systems or buildings without having to worry about discrepancies in measuring. Ultimately, this results in more efficient and effective design processes that help save time and resources.
