If you are going on a plane trip, chances are you will have to bring some luggage. Airlines set requirements for the size and weight of the luggage that you can take on the plane. That is why you have to measure your luggage correctly. Start by making sure you know exactly what you are getting when you buy a new suitcase. Then take the most common measurements, including linear centimeters, weight and height, depth and width. Taking these measurements beforehand can save you some headaches at the airport.

Method 1 of 2: Selecting the right suitcase

1. Check the airline's requirements. Each airline has slightly different requirements for checked baggage and carry-on baggage. You should be able to find that information on the airline's website, usually under "FAQs".
   • Keep in mind that the airline's website has the most current information.
2. Make sure cases with extensions are within size requirements. Some cases have a small zipper along the edge that does not open in a new section, but instead extends the case. If you think you should use this extension, make sure to measure your bag with it open and unpacked.
3. Check the seller measurements list on their websites. Many suitcase and bag sellers will advertise that their bags are suitable for use as hand luggage. They also list dimensions that seem to fit most airlines' carry-on size requirements. But always measure the suitcase yourself before packing it and taking it to the airport. Different airlines have different requirements, and sellers don't always have accurate measurements.
4. Measure your suitcase once it is packed. Your suitcase may fit the airline's requirements if it is empty, but if you add your items to it, its dimensions may change. Pack everything you need to take and measure the suitcase again.
5. Compare the dimensions of hand baggage and normal baggage. Most airlines allow you to bring a larger bag when you check it in. Make sure you know if you are carrying the suitcase or if you are checking it in, and that you meet the airline's size requirements for the type of suitcase you have chosen.
   • Most airlines have strict weight requirements for checked baggage. Make sure to weigh your suitcase after it is fully packed to make sure it meets those requirements.

Method 2 of 2: Measure

1. Measure the total linear inches of your suitcase. Because suitcases can come in so many different shapes and sizes, some airlines simply give a linear inch or centimeter dimension that your suitcase should fit under. Measure the length, height and depth of your suitcase, including handles and wheels. Add those three dimensions together. The total is your linear measurement, in centimeters or inches.
2. To determine the height, measure from the wheels to the top of the handle. Some sellers list height as the "standing" measurement. To get the height of your suitcase, measure from the bottom of the wheels (if your bag has wheels) to the top of the handle.]
   • If you're using a backpack, leave it on its end and measure from end to end.
3. To determine the depth, measure from the back of your suitcase forward. The depth refers to how deep your suitcase is. So for depth you need to measure from the back of your suitcase (where your clothes rest when you pack) to the front (which usually has extra zip and hand pockets).
4. Measure to determine the width from one edge to the other. To measure the width of your suitcase, position it so that you are facing your luggage straight from the front. Then measure across the front of your suitcase. Make sure to include any side handles in the measurements.
5. Weigh your bag with a scale. Each airline has a weight limit for carry-on and checked baggage. Keep in mind that your suitcase already weighs a little, even if it is empty. If you have a scale at home, weigh the suitcase after it is fully packed. It can help you avoid annoying costs or having to throw away items at the airport.
