What Size Is A Carry On Bag? This is a crucial question for stress-free travel, and WHAT.EDU.VN is here to provide a clear and concise answer. We’ll break down the carry on luggage size restrictions, ensuring you avoid any unexpected gate-side baggage fees. Learn about carry on dimensions and travel with confidence, knowing your luggage meets airline requirements.
1. Understanding Carry-On Luggage Sizes
Navigating the world of carry-on luggage sizes can feel overwhelming. Airlines have different restrictions, and exceeding these limits can lead to fees and the inconvenience of checking your bag. Let’s break down the essentials to help you choose the right size for your next trip.
1.1. Domestic vs. International Carry-On Size
The first thing to understand is the difference between domestic and international carry-on size restrictions. Generally, domestic flights allow for slightly larger carry-ons. However, international flights often have stricter size and weight limits.
- Domestic Carry-On: Usually around 22 x 14 x 9 inches.
- International Carry-On: Can range from 15.7-22 inches in height, with varying widths and depths.
1.2. Maximum Carry-On Size: The Overhead Bin Factor
The maximum carry-on size is determined by whether your bag can fit comfortably in the overhead bin. Most overhead bins are designed to accommodate bags that are 22 inches tall, including the wheels. If your bag is larger, it may need to be placed sideways, taking up valuable space.
1.3. Personal Items: What Fits Under the Seat?
In addition to your carry-on bag, airlines typically allow a “personal item.” This is a smaller bag that fits under the seat in front of you. Common examples include:
- Purses
- Laptop bags
- Small backpacks
- Briefcases
It’s important to note the dimensions for personal items as well, as they also have size restrictions.

Note: Always check the airline’s website for the most up-to-date information, as policies can change.
2.3. Understanding Linear Inches
Some airlines, like Hawaiian Airlines and Singapore Airlines, use “total linear inches” to determine carry-on size. This is calculated by adding the length, width, and height of the bag. For example, a bag that is 22 inches long, 14 inches wide, and 9 inches deep has a total of 45 linear inches (22 + 14 + 9 = 45).
2.4. The Importance of Weight Limits
While many domestic airlines don’t enforce weight limits for carry-on bags, international airlines often do. Exceeding the weight limit can result in fees. Even if there’s no strict weight limit, it’s wise to pack light enough to easily lift your bag into the overhead bin.
3. How to Measure Your Carry-On Bag: A Step-by-Step Guide
Ensuring your carry-on bag meets the airline’s size requirements starts with accurate measurements. Here’s a step-by-step guide on how to measure your bag correctly.
3.1. What You’ll Need
- A measuring tape or ruler
- Your carry-on bag
- A notepad and pen (or a smartphone) to record the measurements
3.2. Measuring the Length
Place the measuring tape at the bottom of the bag and extend it to the top, including any handles or protrusions. Record this measurement as the “length.”
3.3. Measuring the Width
Measure the bag from side to side at its widest point. This is typically across the front of the bag. Record this measurement as the “width.”
3.4. Measuring the Depth
Measure the bag from front to back at its thickest point. This is usually the depth of the main compartment. Record this measurement as the “depth.”
3.5. Including Wheels and Handles
When measuring, always include the wheels and handles, as these contribute to the overall dimensions of the bag.
3.6. Calculating Linear Inches (If Required)
If the airline uses linear inches, add the length, width, and depth together: Length + Width + Depth = Total Linear Inches.
3.7. Double-Checking Your Measurements
It’s always a good idea to double-check your measurements to ensure accuracy. A small error could mean the difference between a smooth boarding process and having to check your bag.
4. Choosing the Right Carry-On Bag: Factors to Consider
Selecting the perfect carry-on bag involves more than just size. Consider these factors to find a bag that meets your needs and makes travel easier.
4.1. Hard vs. Soft Shell Luggage
- Hard Shell: Durable and protective, ideal for fragile items.
- Soft Shell: More flexible and can often be squeezed into tight spaces.
4.2. Spinner vs. Roller Bags
- Spinner: Four wheels that rotate 360 degrees, offering easy maneuverability.
- Roller: Two wheels that require tilting the bag to roll.
4.3. Weight of the Bag
Consider the weight of the empty bag, especially if you’re flying with an airline that has strict weight limits. Lightweight options allow you to pack more without exceeding the limit.
4.4. Compartments and Organization
Look for bags with multiple compartments and pockets to keep your belongings organized and easily accessible.
4.5. Durability and Quality
Invest in a high-quality bag that can withstand the rigors of travel. Look for durable materials, sturdy zippers, and reinforced handles.
4.6. Style and Design
Choose a bag that reflects your personal style and is easy to identify on the baggage carousel (if you end up having to check it).
5. Packing Tips for Carry-On Luggage: Maximizing Space and Staying Organized
Packing efficiently is key to making the most of your carry-on space. Here are some tips to help you pack like a pro.
5.1. Roll Your Clothes
Rolling your clothes instead of folding them can save space and minimize wrinkles.
5.2. Use Packing Cubes
Packing cubes help compress your clothes and keep them organized, making it easier to find what you need.
5.3. Utilize Empty Spaces
Stuff socks and small items into shoes and hats to make the most of every inch of space.
5.4. Wear Your Heaviest Items
Wear your bulkiest shoes, jackets, and sweaters on the plane to save space in your bag.
5.5. Downsize Toiletries
Use travel-sized toiletries or purchase reusable travel containers to reduce bulk.
5.6. Plan Your Outfits
Plan your outfits in advance to avoid overpacking. Choose versatile items that can be mixed and matched.
6. What Not to Pack in Your Carry-On: TSA Guidelines
Knowing what you can and cannot pack in your carry-on is crucial for a smooth security screening. Here are some items that are prohibited or restricted by the TSA.
6.1. Liquids Rule: The 3-1-1 Rule

- Flammable liquids and solids

- Sporting equipment (bats, clubs) is prohibited
- Tools (hammers, drills) are prohibited
6.4. Medications and Medical Devices
Medications in liquid form are exempt from the 3-1-1 rule but should be declared to a TSA officer. Medical devices such as CPAP machines are allowed but may require additional screening.
6.5. Food Items
Most food items are allowed in carry-on baggage, but some may be subject to additional screening. Liquids and gels (such as yogurt or peanut butter) must adhere to the 3-1-1 rule.
7. Common Mistakes to Avoid When Choosing a Carry-On Bag
Choosing the wrong carry-on bag can lead to stress and added expenses. Here are some common mistakes to avoid.
7.1. Not Checking Airline Restrictions

7.3. Ignoring Weight Limits
Even if a bag fits the size requirements, exceeding the weight limit can lead to fees, especially on international flights.
7.4. Sacrificing Quality for Price
Choosing a cheap, low-quality bag may seem like a good deal, but it may not withstand the rigors of travel. Invest in a durable bag that will last.
7.5. Overlooking Comfort and Convenience
Consider the comfort and convenience of the bag. Look for features like padded handles, smooth-rolling wheels, and easy-access compartments.

Choose a bag with security features such as lockable zippers or RFID-blocking pockets to protect your belongings.
