How Big is a Quart-Sized Bag? Everything You Need to Know

If you frequently travel by plane, you’ve probably heard of the TSA’s (Transportation Security Administration) 3-1-1 rule.

This rule states that all liquids, aerosols, and gels that you carry on a plane must be in containers that are 3.4 ounces (100 milliliters) or less and placed in a clear quart range bag.

But how big is a quart-size bag?

In this article, we’ll explore everything you need to know about quart-sized bags, including their dimensions, how to use them, and some tips for packing efficiently.

What is a Quart Sized Bag?

A quart-sized bag is a clear plastic bag designed to hold 3.4 ounces (100 milliliters) or less liquids, aerosols, and gels.

The TSA requires these bags to make the security screening process more efficient and ensure all passengers’ safety.

When considering the size limitations for liquids in your quart-sized bag, it’s essential to know the rules, especially if you’re wondering, “Can you put carbonated beverages in checked luggage?”

Dimensions of a Quart-Sized Bag

A quart-sized bag has specific dimensions that must be followed to comply with TSA regulations. It must measure 7 x 8 inches (17.8 x 20.3 centimeters) or have a volume of 1 quart (0.946 liters).

It’s important to ensure the bag doesn’t exceed these dimensions, including closures like zippers or snaps.

Purpose of a Quart Size Bag

The primary purpose of a quart-size bag is to facilitate the screening process at airport security checkpoints. Restricting the number of liquids that passengers can carry in their carry-on luggage helps prevent potential threats and ensures the safety of all passengers aboard the aircraft.

The quart-size bag is a convenient container to hold small travel-sized bottles of liquids.

The TSA Approved Quart Size Bag Dimensions

The Transportation Security Administration (TSA) has specific guidelines for the size of quart bags that can be carried on an airplane. According to the TSA, the dimensions of a quart-sized bag for carry-on luggage should not exceed 7″ x 8″ inches1. However, other sources suggest that the approximate dimensions of a quart-sized bag can be 6″ x 9″ inches.

These bags store liquids, aerosols, gels, creams, and pastes per the TSA’s 3-1-1 rule for carry-on luggage. This rule states that all liquids must be in containers holding 3.4 ounces (100 milliliters) or less and in a clear, quart-size plastic bag. Each passenger is allowed to bring one quart-size bag in their carry-on luggage.

It’s important to note that the dimensions provided are for the length and width of the bag, but no specific depth is mentioned. Therefore, some bags with the dimensions of 6″ x 9″ or 7″ x 8″ may have a volume exceeding 1 quart.

Various available products are marketed as TSA-approved quart-sized bags with 7″ x 5.5″ x 1.5″ inches dimensions. Sticking to the official dimensions as closely as possible is recommended to avoid any issues at the airport security checkpoint.

What Items Are Allowed in My TSA Approved Quart Size Bag?

Your TSA-approved quart-size bag can carry liquids, aerosols, gels, creams, and pastes in travel-size containers that are 3.4 ounces (100 milliliters) or less per item.

These items must fit in a clear, quart-size, resealable plastic bag. Common travel items that must comply with the 3-1-1 liquids rule include toothpaste, shampoo, conditioner, mouthwash, lotion, liquid foundation, liquid eyeliner or mascara, and aerosol sprays for the body like perfume, deodorant, hair spray, or shaving cream.

Each passenger is limited to one quart-size bag of these items in their carry-on luggage. There are exceptions for medications, baby formula/food, and breast milk, which are allowed in reasonable quantities exceeding 3.4 ounces (100 milliliters) and must be declared to the TSA officer at the checkpoint for inspection.

How to Pack a Quart Size Bag

Packing a quart-size bag for air travel, particularly for your carry-on luggage, requires careful planning and organization due to the TSA’s liquid restrictions. Here are some steps to help you pack your quart-size bag effectively:

  1. Understand the TSA Liquids Rule: The TSA allows you to bring liquids, aerosols, gels, creams, and pastes in containers no larger than 3.4 ounces (100 milliliters) in your carry-on luggage. These must fit in a quart-sized, resealable bag. This is the 3-1-1 rule (3.4 oz, 1 single quart-sized bag per 1 person).
  2. Choose the Right Bag: The bag must be clear and have a zip top. It can be a reusable bag. The TSA-approved bag size is one quart. There are various products available that are marketed as TSA-approved quart-sized bags. Sticking to the official dimensions as closely as possible is recommended to avoid any issues at the airport security checkpoint.
  3. Select Your Items: The items that must fit into a quart-sized bag include liquids, aerosols, gels, creams, and pastes, and no single item can exceed 3.4 ounces. Consider the things you’ll need during your trip, and put those in your carry-on. For example, if you’re traveling for a week, you’ll likely need more shampoo and conditioner than you would if you were only away for a weekend.
  4. Pack Your Items: Place your items in the quart-size bag. Be strategic about the liquids you choose. If you have larger amounts of liquid (or larger containers), you can place these in your checked baggage.
  5. Prepare for Screening: Make sure you are ready to be screened as soon as you hit the front of the TSA checkpoint line. Have your 3-1-1 compliant liquids bag out and ready. This will make the screening process smoother and faster.

Remember, each passenger can bring one quart-size bag in their carry-on luggage. If you have more liquids, gels, and aerosols that are over 3.4 oz or 100 ml, it’s recommended to pack them in your checked baggage.

Tips for Using a Quart Size Bag Effectively

Here are some valuable tips to make the most of your quart-size bag:

  1. Plan ahead: Check the TSA guidelines to familiarize yourself with the rules and restrictions regarding liquids. This will help you pack efficiently and avoid any last-minute hassle.
  2. Opt for travel-sized products: Purchase travel-sized toiletries or transfer your regular-sized products into smaller containers. This will save space in your quart-size bag and ensure compliance with the regulations.
  3. Use reusable quart-size bags: Instead of single-use plastic bags, consider investing in a durable, reusable quart-size bag. It is an eco-friendly option that can withstand multiple trips.

Advantages of Using a Quart Size Bag

Using a quart-size bag for air travel has several advantages:

  1. Convenience: A quart-size bag allows you to organize your liquids and keep them separate from other items in your carry-on luggage. This makes the security screening process quicker and more efficient.
  2. Compliance with Regulations: By using a quart-size bag, you adhere to the TSA regulations, preventing any issues or delays during security checks.
  3. Prevents Spillage: The resealable nature of the quart-size bag minimizes the risk of liquid items leaking or spilling inside your luggage, keeping your belongings clean and dry.
  4. Eco-Friendly: Instead of using single-use plastic bags, consider investing in a durable, reusable quart-size bag. It is an eco-friendly option that can withstand multiple trips.
  5. Maximizes Space: The quart-size bag’s dimensions of 7 x 8 inches (17.8 x 20.3 centimeters) or 1 quart (0.946 liters) in volume are designed to ensure that all passengers can carry on the appropriate amount of liquids, aerosols, and gels.

Alternatives to a Quart Size Bag

While the most common option for carrying liquids in carry-on luggage is a quart-sized Ziploc bag, several alternatives meet TSA requirements. These alternatives must adhere to the 3-1-1 rule, meaning they must be transparent, resealable, and quart-sized.

  1. Reusable Liquid Bags: There are many reusable liquid bags available on the market that are designed to meet TSA requirements. These bags are often more durable than standard Ziploc bags, reducing the risk of leaks and spills.
  2. Clear TSA-Approved Toiletry Bags: These bags are designed for air travel and are available in various sizes. They are made from clear, durable materials, making it easy for TSA agents to inspect the contents without opening the bag.
  3. Travel-Sized Containers: While not a bag, travel-sized containers can be used with a clear, resealable bag to carry liquids. These containers are typically 3.4 ounces (100 milliliters) or less, making them compliant with TSA regulations.

Remember, even with these alternatives, you must still adhere to the TSA’s 3-1-1 rule for liquids in carry-on luggage. Each passenger is allowed one quart-sized bag of liquids, gels, and aerosols in travel-sized containers of 3.4 ounces or 100 milliliters or less.
