Measure your suitcase by its height, width, and depth—including wheels and non-retractable handles—with the telescopic handle retracted. The catch is that airline restrictions often measure exterior dimensions, while your packing space depends on interior capacity, which manufacturers list in liters or cubic inches.
Common Measurements for Suitcase Size
When it comes to measuring suitcase size, there are two primary measurements to consider: the exterior dimensions and the interior capacity. Let's take a closer look at each of these measurements.
Exterior Dimensions
The exterior dimensions of a suitcase refer to the overall measurements of the suitcase, including its height, width, and depth. These dimensions are typically measured in inches or centimeters. It's important to note that luggage manufacturers often include the wheels and handles in the exterior dimensions, so make sure to check if the measurements provided include these additional features.
To measure the exterior dimensions of your suitcase, use a tape measure and position the suitcase on a flat surface. Start by measuring the height of the suitcase. Stand it upright and measure from the floor to the highest fixed point, including wheels and any top handle if it does not retract fully. Next, measure the width of the suitcase. Position the tape measure across the suitcase at its widest point and measure from one side to the other. Lastly, measure the height of the suitcase. Ensure that the wheels are included in the measurement, but keep the telescopic handle retracted if it is meant to be stored that way during travel. To determine the interior capacity of your suitcase, check the manufacturer's specifications, which typically list capacity in liters or cubic inches.
Interior Capacity
The interior capacity of a suitcase refers to the amount of space available inside the suitcase for packing your belongings. It is typically measured in liters or cubic inches. The interior capacity is an important consideration when determining if your suitcase can accommodate all the items you need for your trip.
This is a more reliable method than attempting to measure it yourself.
It's important to check the requirements of your airline before you travel to avoid any surprises or additional costs at the airport. If you're flying with a carrier like Southwest, you may also want to confirm how much can your suitcase weigh on Southwest to avoid fees.
Measuring the Exterior of a Suitcase
Measuring the exterior dimensions of a suitcase is an important step in determining if it meets the size restrictions set by airlines.
- Place your empty suitcase on a flat surface, such as the floor or a table.
- Next, measure the width of the suitcase.
- Lastly, measure the depth of the suitcase. Stand it upright and measure from the front to the back at the thickest point.
- Once you have obtained all three measurements, add them together to get the total exterior size of your suitcase.
Remember to record the measurements in either inches or centimeters, depending on the units used by the airline. It's crucial to check the specific size restrictions of your airline, as each airline may have different requirements for both carry-on and checked-in luggage.
By accurately measuring the exterior dimensions of your suitcase, you can confidently determine if it meets the size restrictions, helping you avoid any issues or additional fees at the airport. Additionally, knowing the measurements will also assist you in selecting the appropriate size suitcase for your travel needs.
Measuring the Interior Capacity of a Suitcase
This is the standard method and avoids the impracticality of alternative approaches.
If you need to measure the exterior dimensions for reference, follow these steps:
- Next, measure the width of the suitcase.
- Lastly, measure the height of the suitcase.
Keep in mind that this measurement is an estimate of the interior capacity, as the shape and design of the suitcase can affect the available packing space. It's essential to consider any compartments, pockets, or dividers that may reduce the effective capacity.
This knowledge is especially valuable when planning for longer trips or when needing to account for specific items, such as clothes, shoes, or travel essentials.
Different Methods of Measuring Suitcase Size
Exterior Dimensions
The most common method of measuring suitcase size is by measuring the exterior dimensions.
Linear Inches
Another method used to measure suitcase size is by calculating the linear inches. This method calculates the total of the height, width, and depth of the suitcase. For example, if your suitcase measures 20 inches in height, 14 inches in width, and 8 inches in depth, the linear inches would be 20 + 14 + 8 = 42 inches. Some airlines have specific requirements for maximum linear inches allowed for both carry-on and checked luggage.
Lastly, measure the depth of the suitcase.
Weight Restrictions
In addition to size restrictions, airlines also impose weight restrictions on luggage. While not directly related to size, it is important to consider the weight of your suitcase to ensure it falls within the limits set by the airline. Exceeding weight limits can result in additional fees or the need to repack your belongings.
Volume Measurement
Some suitcase manufacturers provide the interior capacity of their suitcases in liters or cubic inches. This measurement gives you an idea of the amount of space available for packing your belongings.
It's important to check the specific requirements of the airline you will be flying with to avoid any surprises or issues at the airport.
Suitcase Size Restrictions by Airlines
Here's a general overview of suitcase size restrictions set by airlines:
Carry-On Luggage
For carry-on luggage, most airlines enforce a maximum size limit for both the length, width, and height of the suitcase. The typical dimensions allowed range from 45 to 56 linear inches (length + width + height).
The weight limit can range from 15 to 22 pounds (7 to 10 kilograms), again varying by airline. It's important to consider not only the size but also the weight of your carry-on suitcase to ensure compliance with airline regulations.
Checked Luggage
Checked luggage generally has higher size allowances compared to carry-on luggage. The maximum size limit for checked luggage can range from 62 to 80 linear inches (length + width + height).
Similar to carry-on luggage, airlines also impose weight restrictions on checked bags, ranging from 50 to 70 pounds (23 to 32 kilograms), depending on the airline.
Factors to Consider When Measuring Suitcase Size
When measuring the size of a suitcase, there are various factors that you should take into consideration. These factors can help you determine if a suitcase meets your specific travel needs and whether it complies with airline size restrictions. Here are some key factors to consider:
Size Restrictions
First and foremost, consider the size restrictions set by the airlines you will be traveling with. Ensure that the exterior dimensions of your suitcase fall within the specified limits to avoid any issues at the airport.
Type of Travel
Next, think about the type of travel you will be undertaking. If you're going on a short business trip or a weekend getaway, a compact carry-on suitcase may be sufficient. However, for longer trips or vacations, a larger checked suitcase might be necessary to accommodate all your belongings. Consider the duration of your trip and the items you intend to pack when choosing the size of your suitcase.
When measuring your suitcase, start by measuring the height.
Personal Packing Preferences
Everyone has different packing preferences and habits. Some individuals prefer to pack light and travel with only a carry-on suitcase, while others may prefer to have more options and opt for a larger checked bag. Consider your personal packing style and the number of items you typically travel with. If you tend to pack more, a larger suitcase may be more suitable for you.
Durability and Weight
When measuring suitcase size, it's also important to consider the suitcase's durability and weight. Look for a suitcase made from sturdy materials that can withstand the rigors of travel. Additionally, consider the weight of the suitcase itself, as it will contribute to the overall weight of your luggage. Lighter suitcases can be beneficial, especially if you're trying to avoid exceeding weight limits set by airlines.
Storage and Organization
Think about the storage and organization features that are important to you. Suitcases come with various compartments, pockets, and dividers that can help keep your belongings organized and easily accessible. Consider the number and size of these compartments based on your storage needs.
By considering these factors when measuring suitcase size, you can ensure that you choose the right suitcase that suits your travel requirements. Whether you prioritize size restrictions, personal packing preferences, durability, weight, or storage features, finding the perfect suitcase will enhance your travel experience and make packing and unpacking a breeze.
Conclusion
Measuring suitcase size is an important aspect of travel preparation.
This allows you to gauge how much you can pack and ensure that it can accommodate all your belongings comfortably.
Different methods can be used to measure suitcase size, including linear inches, weight restrictions, and volume measurement. Before your trip, it's crucial to check the size restrictions of the airline you'll be flying with, as each airline may have specific requirements.
Remember that measuring suitcase size is about finding the balance between meeting airline requirements and fulfilling your personal packing preferences. Choose a suitcase that suits your needs, is durable, lightweight, and provides sufficient storage and organization options.
