If you have to catch a flight, you will most likely take some baggage with you. Since airlines have specific requirements regarding the size and weight of baggage allowed on board, you will need to measure your suitcases correctly. Start by making sure you know what you are buying when choosing a new suitcase, then take the most common measurements such as linear centimeters, weight, length, width and width in advance to save yourself a lot of headaches at the airport.
Steps
Method 1 of 2: Choose the Right Suitcase
Step 1. Check your airline's baggage requirements
Each airline has slightly different requirements on carry-on and check-in baggage; such information is available on the company's website, usually in the "Frequently Asked Questions".
Remember that the airline's website contains the most up-to-date information
Step 2. Make sure the expandable parts of the suitcase are within the required dimensions
Some suitcases have a zipper along one side which serves not to open a new compartment, but to expand the suitcase - if you intend to use this expansion, be sure to measure the suitcase when it is unfolded.
Step 3. Double-check the measurements on the retailer's websites
Many suitcase retailers advertise their products as "carry-on eligible" and list the most common carry-on sizes of most airlines. However, always measure your suitcase before packing up and taking it to the airport - each airline has its own requirements and retailers don't always have precise measurements.
Step 4. Measure the bag after filling it
Your suitcase may meet airline requirements when empty, but once filled, the size can change - put everything you need to bring in and take your measurements.
Step 5. Compare the measurements between carry-on and hold luggage
Most airlines allow you to bring a larger suitcase to check in. Make sure you are aware of whether you are carrying carry-on or hold baggage and that you know your airline's requirements for the type of baggage you have chosen.
Most airlines have strict requirements on the weight of the checked baggage, so be sure to weigh your suitcase after filling it to make sure it meets the weight limits
Method 2 of 2: Taking Measurements
Step 1. Measure the total linear centimeters of the suitcase
Since the suitcases can have many different shapes and sizes, some airline companies indicate the measurement in linear centimeters for the suitcase. Measure the height, length and width of the suitcase, including handles and wheels, then add these measurements together: the total is the linear measure, expressed in centimeters.
Step 2. Measure from the wheels to the handle for height
Some retailers indicate height as the vertical measurement; to get it, measure from the base of the wheels, if your suitcase has one, to the top of the handle.
If you're using a duffel bag, stand it up and measure from end to end
Step 3. Measure from the back to the front of the suitcase to get the width
The width indicates how deep the suitcase is, so you will need to measure from the back of the suitcase, i.e. the side where you put your clothes, to the front, which usually has an extra zipper and several pockets.
Step 4. Measure side to side for the width
To measure the width of the suitcase, you'll need to stand in front of it and measure the front horizontally, making sure to include the handles as well.
Step 5. Weigh the suitcase with a scale
Each airline has a weight limit for hand and hold baggage. Consider that the suitcase already has its own weight, even when it is empty; if you have a scale at home, weigh the suitcase after you have finished filling it, so you will avoid paying a penalty or having to remove items from the suitcase at the airport.
