If you're traveling somewhere by plane, chances are you'll need to take your luggage with you. Since every airline has provisions on the size and weight of baggage that can be carried on board, you need to measure your baggage appropriately. Start by making sure you know what size you get when you buy a new bag. Then, measure some common things, including linear centimeters, weight, height, thickness, and width. Measuring all of these things before you travel can save you from getting tired at the airport.
Step
Method 1 of 2: Choosing the Right Bag
Step 1. Check all airline-specified bag conditions
Each airline has slightly different provisions for checked baggage and carry-on baggage. You can find this information on the airline's website, usually under the "Frequently Asked Questions" menu.
Keep in mind that the airline's website will have up-to-date information
Step 2. Make sure the bag expansion still meets the size requirements
Some bags have a small zipper around the edge that doesn't open into a new section, but expands your bag. If you think this expansion will be used, make sure you measure the bag in the zipped closed state as well as the expanded state.
Step 3. Double-check the size list that the seller has released on their website
Many luggage sellers advertise that their bags are "cabin eligible." They will also write down all sizes that are most likely to meet the cabin baggage size requirements. But always measure your bag before packing and taking it to the airport. Every airline has different terms, and sellers don't always have an accurate measure.
Step 4. Measure the bag after packing
Your bag may meet airline requirements when it's empty, but putting everything in the bag can change its dimensions. Pack all the things you need to bring, then re-measure.
Step 5. Compare checked and cabin baggage sizes
Most airlines allow you to bring a larger bag if you check it in at check-in. Make sure you know you will be bringing the bag into the cabin or checking it in at check-in, and that you are aware of the airline's sizing requirements for the type of bag you choose.
Most airlines have strict rules regarding the weight of checked baggage. Make sure you weigh the bag, once it's fully packed, to make sure it still weighs within the limits
Method 2 of 2: Taking Measurements
Step 1. Measure the total linear centimeters of the bag
Because bags can come in many different shapes and sizes, some airlines only provide a maximum linear inch or linear centimeter to follow. Measure the length, height and thickness of your bag, including handles and wheels. Add the three sizes. The total sum is the linear size of the bag, in centimeters or inches.
Step 2. Measure the height from the wheel to the top of the handle
Some sellers write height as an "upright" measure. To get the bag's height, measure from the bottom of the wheel (if your bag has wheels) to the top of the handle.
If you are using a duffle bag, stand the ends and measure from one end to the other
Step 3. Measure the thickness from the back of the suitcase to the front
Thickness means how deep your suitcase is. So, for thickness, you should measure from the back of the suitcase (where your clothes are placed) to the front (which usually has extra zippers and pockets).
Step 4. Measure the width from one edge to the other
To measure the width of the suitcase, you need to place the suitcase parallel in front of you. After that, measure the latitude of the front of your bag. Make sure you include the side handles in the measurement.
Step 5. Weigh the bag with a scale
Each airline has weight limits for checked and cabin baggage. Consider that your bag also weighs, even when it's empty. If you have a scale at home, weigh your bag once it's full. This can help you avoid expensive extra fees or having to dump some items at the airport.
