Measure Luggage Size

Tools Needed
Before you start measuring, gather a few simple tools. You don’t need anything fancy—just items you probably already have at home:
- Flexible tape measure: This is the best tool because it wraps around curves and corners, giving you the most accurate numbers.
- Ruler: Works for smaller bags or to double-check measurements.
- Book: Helps you get a straight line when measuring height.
- Digital luggage scale: Handy for checking weight, especially if you want to avoid surprises at the airport.
- Bathroom scale: If you don’t have a luggage scale, this works too. Weigh yourself, then weigh yourself holding the bag, and subtract.
Tip: Always measure your suitcase when it’s fully packed. This way, you get the true luggage size, including any bulges or stuffed pockets.
Dimensions to Measure
Airlines check three main dimensions for every bag. You need to measure all of them to make sure your luggage size fits the rules.
Dimension Type | Measurement |
---|---|
Maximum Linear Dimensions | 62 linear inches (length + width + height) |
Maximum Weight | 50 pounds (23 kg) |
- Height: Measure from the floor to the top of the suitcase, including wheels and any pushed-down handles. Don’t extend telescopic handles.
- Width: Measure the side-to-side distance at the widest point.
- Depth: Measure from the front to the back, including any pockets or bulges.
Airlines always include wheels and handles in the luggage size. Push down any soft or telescopic handles before measuring.
Most airlines use the “linear inch” rule for checked bags. This means you add up the height, width, and depth. If the total is 62 inches or less, you’re good to go. If it’s more, you might pay extra fees.
- Standard checked baggage dimensions usually max out at 62 linear inches.
- The weight limit for checked luggage is often 50 pounds (23 kg).
- Business and first-class tickets sometimes allow up to 70 pounds (32 kg).
Step-by-Step Guide
Ready to measure? Follow these steps for the most accurate results:
- Pack your suitcase completely. Fill it as you would for your trip. This helps you measure the real luggage size, not just the empty shell.
- Stand the suitcase upright on a hard floor. Place it against a wall for stability.
- Measure the height. Put a book flat on top of the suitcase. Use your tape measure to check the distance from the floor to the bottom of the book. Make sure you include the wheels and any handles that don’t retract.
- Measure the width. Lay the suitcase on its back. Measure the widest part from side to side.
- Measure the depth. Still on its back, measure from the front to the back, including any bulging pockets.
- Calculate the linear inches. Add the height, width, and depth together. This number is your total luggage size for airline rules.
- Check the weight. Use a digital luggage scale or a bathroom scale. Weigh the bag after packing to make sure you don’t go over the airline’s limit.
Note: Understanding and calculating linear inches is super important. It helps you avoid extra fees and makes sure your luggage size meets airline standards.
Extra Tips for Accurate Measurement
- Always measure with the suitcase packed, not empty.
- Double-check that you include wheels and handles.
- Use a flexible tape measure for curved or soft-sided bags.
- Weigh your bag before and after packing, and right before you leave.
- Try a luggage weight tracker app or a smart suitcase if you want to get fancy.
By following these steps, you can feel confident that your luggage size will pass airline checks. No more last-minute stress at the airport!
Airline Rules
Where to Check
You want to make sure your luggage size fits the airline’s rules before you pack. The best way to find the latest information is to check the airline’s official website. Most airlines have a baggage policy page that lists size and weight limits for carry-on, checked, and personal items. Here are some places you can look:
- The airline’s official baggage policy page. For example, American Airlines posts their checked bag rules at American Airlines Checked Baggage Policy.
- The airline’s FAQ or help center.
- Your booking confirmation email. Airlines often include luggage details there.
- Airport check-in counters or customer service desks.
Tip: Always check the airline’s website before your trip. Rules can change, and you want the most up-to-date info.

Note: Always measure your bag and check the airline’s rules. Even a small difference in luggage size can mean extra fees.
Updates to Restrictions
Airline policies change all the time. You need to stay alert so you don’t get caught by surprise. In the past two years, some airlines have made big changes:
- American Airlines removed metal bag sizers at boarding gates. This makes carry-on checks less strict, but your bag still can’t go over 45 linear inches.
- United Airlines made a similar change in 2020. More airlines now relax carry-on rules to speed up boarding.
- Some airlines update their weight limits or change what counts as a personal item.
You should always check for updates before you travel. Visit the airline’s website or call customer service if you’re not sure. Rules can change quickly, especially for budget airlines.
Tip: Set a reminder to check luggage rules a week before your flight. You’ll avoid last-minute stress and save money.
Packing Tips
Smart Packing
You want to make the most of every inch in your suitcase. Travel experts share some easy tricks to help you pack smarter and stay within airline rules:
- Roll your clothes instead of folding them. This saves space and helps prevent wrinkles.
- Use packing cubes to organize your items by type. Packing cubes also compress your clothes, so you can fit more.
- Fill your shoes with socks, chargers, or toiletries. This keeps your shoes in shape and uses up empty space.
- Choose items that do double duty. For example, a scarf can work as a blanket or a pillow.
Efficient packing helps you fit more into your bag and keeps the weight down. You can avoid extra fees and skip the stress at the airport. Many travelers do not pack efficiently, so you already have an advantage by following these tips.
Tip: Lay out everything you want to bring, then remove anything you do not really need.
Compression Bags
Compression bags can change the way you pack. Frequent flyers love them for several reasons:
Benefit | Description |
---|---|
Space-saving | Compression bags reduce the volume of your clothes, making packing easier. |
Protection | They keep your things safe from water, dirt, and odors. |
Versatility | You can use them for clothes, pillows, or even soft toys. |
No Vacuum Needed | Some bags work by rolling, so you do not need a vacuum. |
Many travelers say compression bags save up to 80% of space in their luggage. Even if you do not reach that number, you will notice a big difference. You can pack more without going over the size limit.
Weigh Before Travel
Always check your bag’s weight before you leave home. Here is a simple process:
- Use a luggage scale to weigh your packed bag.
- Attach the scale’s strap to your bag handle and lift.
- Compare the weight to your airline’s limit, usually about 50 pounds.
This step helps you avoid overweight fees and last-minute repacking at the airport. You will travel with peace of mind, knowing your bag meets the rules.
Avoid Mistakes
Handles and Wheels
You might think measuring your suitcase is simple, but many travelers forget to include the handles and wheels. Airlines count every part of your bag when they check the size. If you skip these parts, your bag could end up too big for the rules.
- Airlines include handles and wheels in the total measurement.
- Always measure from the very bottom of the wheels to the top of the handle (when not extended).
- Double-check the sides for any extra bulges or pockets.
Tip: Place your suitcase on a flat surface and use a flexible tape measure. Start at the floor and go all the way to the highest point, including wheels and handles.
Weight Limits
Weight limits can sneak up on you. Each airline sets its own rules, and going over can cost you money or cause delays. Here’s a quick look at some common limits:
Airline | Carry-on Weight Limit |
---|---|
Frontier Airlines | 35 lbs |
Hawaiian Airlines | 25 lbs |
Other US Airlines | None specified |
Airline | Size Limit | Weight Limit |
---|---|---|
Alitalia | 62 Linear Inches | 40 Pounds |
All Nippon Airways | 62 Linear Inches | 50 Pounds |
Singapore Airlines | 62 Linear Inches | 55 Pounds |
Airlines check your bag’s weight at the counter. If your bag is under 50 pounds (23 kg), you’re usually safe. If it’s over, you may need to repack or pay extra. Some airlines label bags over 50 pounds as “heavy luggage.” The maximum allowed is often 70 pounds (32 kg), but some airlines have lower limits.
Weight Limit | Consequence |
---|---|
Less than 23KG/50LBS | No extra charges; bag is easy for staff to handle |
More than 23KG/50LBS | May need to repack or get a “heavy luggage” label |
Up to 32KG/70LBS | Allowed on some airlines, but not all |
Double-Check Rules
Mistakes happen when you rush or skip the details. Here are the most common errors travelers make:
- Not checking airline restrictions
- Failing to measure luggage accurately
- Not weighing bags before travel
You can avoid these problems by setting a reminder to review your airline’s baggage policy before you pack. Always measure and weigh your bag after packing. If you’re unsure, check the airline’s website or call customer service. A few extra minutes can save you money and stress at the airport.
Remember: Double-checking now means no surprises later. You’ll travel with confidence and avoid last-minute hassles.
You can have a smooth trip if you follow easy steps. First, look at your airline’s rules and your suitcase’s instructions. Pack your bag, then measure and weigh it to check the limits. Before you go to the airport, check everything again. Here are some quick tips: 1. Spread out the weight in your bag. 2. Use a small scale to weigh your suitcase. 3. Leave some room for things you buy on your trip. If you share or save this guide, you can skip extra fees and pack better every time.
Benefit | Description |
---|---|
Free space | Save money and feel less worried by using all your space. |
Avoiding fees | Stop surprise charges from the airline. |
Efficient packing | Make sure you fit everything you need for your trip. |
