If you’re shopping for luggage or looking at storage container dimensions, you may have come across the phrase ’80 linear inches.’ This seemingly odd measurement can be confusing if you don’t know what it means.

If you’re short on time, here’s a quick answer to your question: 80 linear inches refers to the total of the length, width, and height of an object added together. So an item that is 20 inches long, 15 inches wide, and 10 inches tall would be 45 linear inches (20 + 15 + 10).

Many airlines restrict carry-on luggage to 45 linear inches, while checked bags can go up to 80 linear inches.

In this comprehensive guide, we’ll explain exactly what 80 linear inches means, when it’s used, and how to calculate it yourself for any object. Read on for a full understanding of this measurement.

What Does 80 Linear Inches Mean?

When it comes to travel, understanding measurements is crucial, especially when it comes to luggage. One frequently used measurement in this context is “linear inches.” So, what exactly does 80 linear inches mean?

The Definition of Linear Inches

Linear inches is a measurement used to determine the size of an object by adding together its length, width, and height. It is commonly used in the airline industry to ensure that carry-on and checked luggage adhere to size restrictions.

In simpler terms, linear inches is the sum of the three dimensions of an object.

For example, if you have a suitcase that measures 20 inches in length, 15 inches in width, and 10 inches in height, you would calculate the linear inches by adding these three measurements together: 20 + 15 + 10 = 45 linear inches.

When and Why the Measurement is Used

Airlines often have specific size restrictions for both carry-on and checked baggage. These restrictions are in place to ensure that luggage fits in overhead compartments or under the seat in front of you, as well as in the cargo hold of the aircraft.

When an airline states that the maximum allowed dimensions for carry-on luggage are 22 inches x 14 inches x 9 inches, they are referring to the linear inches as well. By multiplying these measurements together (22 x 14 x 9 = 2772 cubic inches), you get the total volume that the bag can occupy.

Similarly, when airlines state that the maximum allowed dimensions for checked luggage are 62 linear inches, they are referring to the sum of the length, width, and height of the bag. If your bag exceeds this limit, you may be subject to additional fees or have to check it as oversized or overweight luggage.

It’s essential to note that different airlines have different size restrictions, so it’s always recommended to check with the specific airline you’re traveling with to ensure your luggage meets their requirements.

For more information on airline baggage dimensions and restrictions, you can visit www.tsa.gov or the website of the airline you’re flying with.

Calculating 80 Linear Inches

When it comes to understanding what 80 linear inches means, it’s important to know how to calculate it. Linear inches refer to the total measurement of an object’s length, width, and height combined. This measurement is commonly used by airlines to determine the size of luggage that can be carried on board or checked in.

Measuring Length, Width, and Height

To calculate the linear inches of an object, you need to measure its length, width, and height. Using a measuring tape or ruler, measure each side of the object in inches. For example, if you have a suitcase, measure the length, width, and height of the suitcase.

Adding the Numbers Together

Once you have the measurements for the length, width, and height, simply add them together to calculate the linear inches. For instance, if the length of your suitcase is 30 inches, the width is 20 inches, and the height is 10 inches, you would add 30 + 20 + 10, which equals 60 linear inches.

Note: It’s important to keep in mind the specific rules and regulations of the airline or transportation authority you are dealing with, as they may have different size restrictions for carry-on or checked luggage.

Examples of Common Objects

To give you a better idea of what 80 linear inches could look like, here are a few examples of common objects and their corresponding linear inch measurements:

Remember, these are just examples, and the linear inch measurement can vary depending on the dimensions of the object you are measuring.

For more information on airline luggage restrictions and requirements, you can visit the official website of the airline you are planning to travel with. Airlines often provide detailed information on their websites regarding baggage size limitations and fees for exceeding those limits.

Airline Luggage Restrictions

Carry-On Bags: 45 Linear Inches

When it comes to carry-on bags, airlines typically have size restrictions to ensure that they fit in the overhead compartments or under the seat in front of you. One common measurement used to determine the size of carry-on bags is linear inches.

Linear inches is the total sum of the bag’s length, width, and height.

For most airlines, the maximum allowed linear inches for carry-on bags is around 45 inches. This includes the handles and wheels, so it’s important to consider those when measuring your bag. If your bag exceeds the allowed linear inches, you may be required to check it in or pay an additional fee.

It’s worth noting that some airlines have different size restrictions for carry-on bags, so it’s always a good idea to check with your specific airline before your trip.

Checked Bags: 80 Linear Inches

When it comes to checked bags, the maximum allowed linear inches are typically higher than carry-on bags. Airlines usually allow around 80 linear inches for checked baggage. This means that the sum of the bag’s length, width, and height should not exceed 80 inches.

Checked bags are placed in the cargo hold of the airplane, so there is more room to accommodate larger bags. However, it’s important to note that exceeding the maximum allowed linear inches for checked bags may result in additional fees or restrictions.

If you are unsure about the size restrictions for checked bags, it’s always a good idea to check with your airline or refer to their website for specific guidelines.

Why These Limits Exist

Airline luggage restrictions exist for a few reasons. Firstly, it helps ensure the safety and comfort of all passengers. By setting size limits on carry-on bags, airlines can ensure that they fit in the overhead compartments or under the seat, preventing any inconvenience or potential hazards during the flight.

Additionally, luggage restrictions help airlines manage the space available in the cabin and cargo hold efficiently. By imposing limits on both carry-on and checked bags, airlines can accommodate the luggage needs of all passengers and maintain a smooth boarding and disembarking process.

These limits also help airlines regulate the weight of the aircraft, as excessive baggage can affect the plane’s performance. By setting size restrictions, airlines can ensure that the weight and balance of the aircraft are within safe limits.

It’s important to remember that each airline may have slightly different luggage restrictions, so it’s always a good idea to check with your specific airline or refer to their website for the most accurate and up-to-date information.
