Measuring a suitcase is crucial for ensuring it meets the size requirements of your airline or travel destination. Whether you’re embarking on a business trip or an adventurous getaway, knowing the dimensions of your luggage is essential for a smooth and efficient travel experience. By following the proper techniques, you can accurately determine the size of your suitcase and avoid any potential hassles during check-in or baggage claim.

To begin the measurement process, place the suitcase flat on a stable surface. Using a flexible measuring tape, start by measuring the height of the suitcase. Position the tape at the base of the suitcase and extend it vertically to the highest point, including any wheels or handles. Record this measurement as the height. Next, measure the width of the suitcase. Place the tape at the widest point of the suitcase and extend it horizontally across the case. Again, include any protruding elements such as handles or pockets in your measurement. Finally, measure the depth of the suitcase. Position the tape at the front edge of the suitcase and extend it to the back of the case, again including any external features.

Once you have the height, width, and depth measurements, add them together to determine the total linear dimensions of your suitcase. This value typically represents the sum of the three sides in inches or centimeters. Compare the total linear dimensions to the size restrictions set by your airline or travel provider. If your suitcase exceeds these dimensions, you may need to adjust the contents or consider purchasing a smaller case to meet the requirements. By accurately measuring your suitcase, you can ensure a seamless and hassle-free travel experience.

Determining Suitcase Size

To accurately measure a suitcase, you must consider its dimensions: length, width, and height. Here’s a detailed guide to help you determine the size:

Length: Measure the suitcase’s length from the front to the back, excluding any handles or wheels.

Width: Measure the suitcase’s width from side to side, excluding any external pockets or handles.

Height: Measure the suitcase’s height from the bottom to the highest point, including any wheels or handles.

Once you have measured the suitcase’s dimensions, refer to the airline’s baggage size restrictions to determine if it meets the allowed size. Airlines typically specify the maximum permitted dimensions for checked and carry-on luggage.

It’s important to note that some suitcases may include expandable compartments that can increase their volume. If your suitcase has an expandable compartment, measure its dimensions both in its expanded and collapsed state to ensure it complies with the airline’s regulations.

To make the measuring process easier, here’s a table summarizing the steps:

Measurement How to Measure
Length Front to back, excluding handles and wheels
Width Side to side, excluding external pockets and handles
Height Bottom to highest point, including wheels and handles

Measuring Height and Width

When it comes to measuring your suitcase, height and width are the two most important dimensions to know. These measurements will determine whether or not your suitcase will fit in the overhead bin or under the seat on a plane, and they will also help you to determine which size of suitcase is best for your needs.

Measuring Height

To measure the height of your suitcase, place it upright on the ground. Use a tape measure or a ruler to measure from the bottom of the suitcase to the highest point on the lid.

Measuring Width

To measure the width of your suitcase, place it on its side. Use a tape measure or a ruler to measure from the left side of the suitcase to the right side. Be sure to include the wheels and any other protruding parts when measuring the width.

Typically, most airlines have the following size restrictions for carry-on luggage:

Airline Carry-on Size Restrictions
United Airlines 22″ x 14″ x 9″
Delta Air Lines 22″ x 14″ x 9″
American Airlines 22″ x 14″ x 9″
Southwest Airlines 22″ x 14″ x 9″

Determining Depth and Volume

Once you’ve measured the length and width of your suitcase, it’s time to determine its depth. The depth is measured from the base of the suitcase to the highest point, including any wheels or handles.

To measure the depth, place the suitcase on a flat surface. Use a measuring tape or ruler to measure the distance from the base to the highest point. Make sure to measure straight up and down, not at an angle.

Once you have the depth, you can calculate the volume of your suitcase. Volume is measured in cubic inches (cu in) or cubic centimeters (cm³). To calculate the volume, multiply the length, width, and depth of the suitcase. For example, if your suitcase is 20 inches long, 14 inches wide, and 9 inches deep, its volume would be 2,520 cubic inches.

The volume of your suitcase is important to consider when choosing a luggage carrier or checking it on a plane. Most airlines have restrictions on the size and weight of checked luggage. Make sure your suitcase meets the airline’s requirements before you pack it.

Length (inches) Width (inches) Depth (inches) Volume (cubic inches)
20 14 9 2,520
22 16 10 3,520
24 18 11 4,752

Using a Luggage Scale

For a highly accurate measurement, use a luggage scale. These portable devices are readily available online or at luggage stores. Follow these steps to use a luggage scale:

1. Attach Luggage:

Securely attach the scale to the handle of your suitcase.

2. Lift Bag:

Gently lift the suitcase off the ground using the scale’s handle.

3. Read Display:

Observe the display on the scale to obtain the weight of your luggage.

4. Additional Considerations:

  • Tare Weight: Some scales include a "tare" feature. This allows you to subtract the weight of the empty suitcase, ensuring an accurate measurement of its contents.
  • Accuracy: Luggage scales vary in accuracy. For precise measurements, consider using a digital scale with a high weight capacity.
  • Carry-On Restrictions: Airlines and international airports have specific carry-on weight restrictions. Check these regulations before using a luggage scale to verify compliance.
Airline Carry-On Weight Limit
Delta Airlines 40 pounds (18 kg)
United Airlines 40 pounds (18 kg)
Southwest Airlines 44 pounds (20 kg)

Packing Your Suitcase for Optimal Space

1. Choose the Right Size Suitcase

The key to efficient packing is choosing a suitcase that is the right size for your trip. Measure the length, width, and height of your suitcase to ensure it meets the airline’s carry-on or checked baggage requirements.

2. Roll, Don’t Fold

Instead of folding clothes, roll them tightly into cylindrical shapes. This saves space and prevents wrinkles.

3. Use Packing Cubes

Packing cubes help you organize and compress your belongings, maximizing space utilization and keeping your suitcase neat and tidy.

4. Pack Heavy Items First

Place heavy items, such as shoes and electronics, at the bottom of your suitcase to distribute weight evenly and prevent bulges.

5. Utilize Every Nook and Cranny

Fill empty spaces in your suitcase with small items like socks, underwear, or toiletries. Consider using a shoe bag or organizer to fit shoes snugly in the suitcase.

Item Packing Tip
Shoes Stuff with socks or use a shoe bag for organization
Socks and Underwear Fill empty spaces or pack in a separate packing cube
Toiletries Place in a clear bag for easy access and security compliance

6. Measuring a Soft-Sided Suitcase

Measuring a soft-sided suitcase can be a bit trickier than measuring a hard-sided suitcase. Here are some tips:

  1. Make sure the suitcase is fully packed and closed.
  2. Place the suitcase on a flat surface.
  3. Use a measuring tape to measure the height, width, and depth of the suitcase.
  4. Make sure to measure the suitcase from the outside edges, including any handles or wheels.
  5. Add up the height, width, and depth to get the total linear inches.
  6. Compare the linear inches to the airline’s baggage limits. If the suitcase is too large, you will need to repack or pay an overweight baggage fee.
  7. Airline Carry-On Baggage Limit Checked Baggage Limit
    Delta Air Lines 22″ x 14″ x 9″ 62″ linear inches
    United Airlines 22″ x 14″ x 9″ 62″ linear inches
    American Airlines 22″ x 14″ x 9″ 62″ linear inches
    Southwest Airlines 24″ x 16″ x 10″ 62″ linear inches

    Using Measuring Tape

    For most suitcases, the total linear inches are calculated by adding the height, width, and depth, measured in inches. To measure your suitcase using a measuring tape, follow these steps:

    1. Height: Place the suitcase upright on the ground. Measure from the top of the suitcase to the bottom of the base, including any wheels or feet.
    2. Width: Measure the suitcase from the widest point on one side to the widest point on the opposite side, perpendicular to the height.
    3. Depth: Measure the suitcase from the front to the back, including any handles or protrusions.
    4. Add measurements: Sum the height, width, and depth measurements to determine the total linear inches.

    Measuring Tools

    If you don’t have a measuring tape, you can use tools like a yardstick or ruler. However, these tools may not be as accurate as a flexible measuring tape. To measure your suitcase using a rigid tool:

    1. Measuring stick: Place the measuring stick along the side of the suitcase, making sure it extends beyond the top and bottom. Measure the distance from the top of the suitcase to the end of the measuring stick.
    2. Ruler: Divide the suitcase into sections smaller than the length of the ruler. Measure each section separately and add up the measurements to determine the total height, width, or depth.

    Additional Tips for Measuring Suitcases

    When measuring a suitcase, consider the following tips to ensure accuracy:

    Measurement Tip
    Height Measure from the highest point of the suitcase, including handles or protrusions.
    Width Don’t include pockets or zippers in the measurement. Measure the widest part of the suitcase.
    Depth Measure the suitcase when it’s packed and closed. Include any external pockets or compartments.

    Understanding Different Suitcase Dimensions

    There are three main dimensions to consider when measuring a suitcase: length, width, and height. Length is measured from the front to the back of the suitcase, width is measured from side to side, and height is measured from the bottom to the top. It’s important to measure all three dimensions carefully to ensure that your suitcase will meet the carry-on or checked baggage requirements of your airline.

    Linear Inches

    Linear inches are the sum of the length, width, and height of a suitcase. When measuring linear inches, it’s important to follow the airline’s specific guidelines. Some airlines require you to measure the suitcase with the wheels and handles included, while others require you to measure the suitcase without the wheels and handles.

    Most airlines have a maximum linear inch allowance for carry-on and checked baggage. For example, many airlines have a maximum linear inch allowance of 45 inches for carry-on baggage and 62 inches for checked baggage.

    To measure the linear inches of your suitcase, simply add the length, width, and height of the suitcase. For example, if your suitcase is 22 inches long, 14 inches wide, and 9 inches high, the linear inches of your suitcase would be 45 inches (22 + 14 + 9 = 45).

    Here is a table summarizing the linear inch allowances for carry-on and checked baggage for some of the major airlines:

    Airline Carry-On Baggage Checked Baggage
    American Airlines 45 inches 62 inches
    Delta Air Lines 45 inches 62 inches
    United Airlines 45 inches 62 inches
    Southwest Airlines 50 inches 80 inches
    JetBlue Airways 45 inches 62 inches

    Checking Suitcase Compatibility for Storage

    When storing a suitcase, it’s crucial to ensure it fits the designated space. Here are the steps to measure a suitcase for storage:

    1. Measure the Length: Place the suitcase flat on its side and measure the longest distance from one end to the other, excluding wheels or handles.
    2. Measure the Width: Measure the distance from one side to the other, perpendicular to the length. Again, exclude wheels or handles.
    3. Measure the Height: Place the suitcase upright and measure the vertical distance from the bottom to the highest point, including wheels or handles.
    4. Measure the Interior Capacity: To estimate the interior space, multiply the length, width, and height in inches. This will give you the cubic inch capacity.
    5. Consider the Storage Space: Measure the space where the suitcase will be stored, including any shelves or drawers. Ensure the suitcase’s dimensions are smaller than the available space to prevent it from getting stuck or damaged.
    6. Allow for Clearance: Add a few inches of clearance to the suitcase’s dimensions to ensure easy access and prevent it from being too tightly packed.
    7. Measure Any Irregular Shapes: If the suitcase has any unusual shapes or contours, measure those areas separately and add them to the overall dimensions.
    8. Consider Storage Duration: If you plan to store the suitcase for an extended period, factor in the potential for shrinkage or expansion of the materials.
    9. Measure the Grips and Handles: If the storage space is limited in height, measure the grips or handles to ensure they do not protrude above the maximum height.

      Measurements for Common Storage Spaces

      Storage Space Average Dimensions
      Closet Shelves 18-24 inches wide, 12-18 inches deep, 36-48 inches high
      Under-Bed Storage 6-12 inches high, 18-24 inches wide, 36-48 inches deep
      Overhead Storage Compartments 18-24 inches wide, 12-18 inches deep, 12-18 inches high

      Tips for Accurate Suitcase Measurement

      1. Measure the Length

      Lay the suitcase flat on its back, parallel to the ground. Use a measuring tape to measure the length from the outermost point on one end to the outermost point on the other end. Avoid measuring along curves or handles.

      2. Measure the Width

      Stand the suitcase upright on one of its sides. Measure the width from the outermost point on one side to the outermost point on the other side. Make sure the suitcase is fully expanded and not compressed.

      3. Measure the Height

      Stand the suitcase upright on one of its ends. Measure the height from the base of the suitcase to the highest point, including wheels and handles. If there are multiple handles, measure to the top of the highest handle.

      4. Add Wheel and Handle Measurements

      If applicable, add the height of the wheels and handles to the overall measurements. Measure the height of the wheels from the base of the suitcase to the top of the wheel. Measure the height of the handles from the base of the suitcase to the top of the handle.

      5. Convert to Inches if Necessary

      If the measurements are in centimeters, convert them to inches by dividing by 2.54.

      6. Check Airline Regulations

      Before purchasing or packing a suitcase, check the airline’s baggage regulations to ensure your suitcase meets the size and weight restrictions.

      7. Measure Twice, Pack Once

      To avoid surprises at the check-in counter, measure your suitcase twice and write down the measurements. This will give you peace of mind and ensure you have accurate information when packing.

      8. Use a Suitcase Measuring Tape

      Consider using a suitcase measuring tape, which is specifically designed to measure suitcases accurately. These tapes often have multiple markings for both length and width, making it easier to get precise measurements.

      9. Account for Packing Bulges

      When packing your suitcase, consider leaving a little extra space for inevitable packing bulges. This will help prevent your suitcase from being overstuffed and ensure it zips smoothly.

      10. Pack Smartly

      To maximize space and ensure your suitcase fits within the airline regulations, pack smartly. Roll clothes instead of folding them, and use packing cubes to organize items efficiently. Consider using a vacuum-storage bag to reduce the volume of bulky items.

      Measurement Description
