10 Major Updates in Luggage Dimensions for Airlines Sep 22

By: Sahil Luthra

More often than not you will be traveling with some bags on an airplane.

The thing is, most airplanes have only a limited capacity of space inside their luggage hold, and they have to burn more fuel to lift each pound of extra weight.

For this reason, it is extremely important that you know how to measure the size and weight of luggage you have packed, and see if they are under your airline size and weight restrictions.

Luggage Dimensions

Generally, luggage sizes are published in per-side multiplications, like length x width x height. But airlines do realize that your luggage may be of odd shape.

Measure for Linear Inches

For this reason, airlines now prefer to publish size restrictions in total linear dimensions instead of each-side dimensions.

Measure for Linear Inches

This is the total number of inches or centimeters you count when measuring the bag from three directions. It is generally written as the sum of length + width + height.

Linear Dimensions

An airline may tell you they allow checked bags up to 22” x 14” x 9” – which indicates the length, width and the height of the luggage.

Checked Baggage Dimensions in inches

They may say that the maximum checked bag size in their flights is 45 linear inches – meaning the addition of the ad-hoc length, width, and height of the luggage (22 + 14 + 9).
