Step-by-step Measuring Guide
Knowing the exact size of your carry on luggage is important. It helps you avoid extra fees at the airport. Follow these simple steps to measure your bag correctly.
You will measure three parts: height, width, and depth. Use a tape measure or a ruler for best results.
Measuring Height
Place your luggage on a flat surface. Measure from the bottom to the top of the bag.
Include wheels and handles if they do not retract. These add to the total height.
- Start at the base where the bag touches the floor
- Measure straight up to the highest point
- Include any fixed parts like wheels or handles
Measuring Width
Measure across the widest part of your luggage. This is usually the side that faces out when you carry it.
Keep the tape measure straight to get an accurate width. Do not include any straps or pockets that stick out.
- Find the widest point on the side of the bag
- Measure straight across from one side to the other
- Do not add any loose parts or accessories
Measuring Depth
The depth is how thick your luggage is from front to back. Measure from the front face to the back panel.
Keep the tape measure straight for the best result. Do not include handles or wheels for this measurement.
- Place the tape at the front of the bag
- Measure straight back to the rear side
- Exclude any parts that stick out beyond the main body

Tips For Choosing The Right Bag
Choosing the right carry on luggage makes your travel easier and more comfortable. The right bag fits airline rules and holds your essentials well.
Look at the material and weight before buying. These affect durability and how much you can pack.

- Look for water-resistant materials for wet weather.
- Flexible bags fit overhead bins easier.
- Check if the bag has extra pockets for organization.

Airlines limit carry on weight. A lighter bag lets you pack more without extra fees.
| Type of Bag | Approximate Weight | Benefit |
| Soft fabric carry on | 4 to 6 pounds | Light and flexible |
| Hard shell carry on | 6 to 9 pounds | More protection |
| Lightweight models | 3 to 4 pounds | Easy to carry and pack |
