The TSA has specific requirements for what can be carried on an airplane in terms of both size and type of travel-size containers.
One item that is often question is how big is a quart size bag for carry on.
Many people that air travel frequently want to know how to best pack their carry-on baggage to avoid any delays or hassles at the airport.
There are current TSA regulations that have very specific guidelines about what can and cannot be carried on an airplane, and one item that is often questioned is the quart size bag.
This bag must meet certain size requirements in order to be allowed through airport security.
What exactly are those size requirements? And how can you make sure that your bag meets them?
Read on for everything you need to know about the TSA's quart size bag guidelines.
Quart Size Bag Guidelines
The definition of a quart size bag is a clear, plastic, zip-top bag that has approximate dimensions of 7 x 8 cubic inches.
This is the maximum size bag that is allowed through security. Anything larger than this will not be permitted.
In terms of what can be carried in the quart size bag, each passenger is allowed to bring one quart-sized bag of liquids, aerosols, gels, creams and pastes in their carry-on bag and through the checkpoint.
All liquids, gels and aerosols must be placed in a single, quart-sized, clear plastic, zip-top bag. Only one item per bag is allowed.
Make sure to declare all liquids, gels and aerosols at the security checkpoint for inspection.
Exceptions
There are a few exceptions to the TSA's quart size bag guidelines. Medications, baby formula/food and breast milk are allowed in reasonable quantities exceeding 3.4 ounces (100 milliliters).
Additionally, these items must be declared to the TSA officer at the checkpoint for inspection.
If you have larger containers that are half-full or less, you may pack them in your carry-on bag.
Empty containers that previously held liquids are allowed in carry-on bags.
3-1-1 Rule
In order to make packing your quart size bag easier, remember the 3-1-1 rule.
This rule states that each passenger is allowed to bring one quart-sized bag of liquids, gels, creams and pastes in their carry-on bag and through the checkpoint.
These are limited to travel-sized containers that are 3.4 ounces (100 milliliters) or less per item.
Therefore, all liquids, gels, and consols must be placed in a single, quart-sized, clear plastic, zip-top bag. Only one bag per person is allowed. The bag may be placed in a carry-on bag or in your checked bag.
While there are numerous sizes of baggies and types the approximate dimensions of a quart-size bag should be 7" x 8".
Here are a few examples of TSA-approved quart size bags:
- Ziploc brand bags ( the most popular brand)
- Hefty brand Slider Storage Bags
- Glad brand Slide Lock Steamer Bags
TSA Liquids Rule
The TSA liquids rule is in place to ensure the safety of all passengers on an airplane.
This rule states that each passenger can bring liquids only if they are in containers that hold 3.4 ounces (100 milliliters) or less and all of these containers fit into 1-quart bag.
A great way to add maximum space is to use a smaller container for your liquids and only bring as much as you need.
Items Permitted in Quart-Sized Bags
There are certain items that are permitted in quart sized bags. Any of the following items can be found in a travel size that meets TSA rules.
- Baby formula, baby food, breast milk,and juice for infants or toddlers

For the amount of liquid you have each one can be placed in 3.4 oz bottles and a 1-quart capacity clear plastic bag.
Containers of liquids should be tightly sealed and placed in the correct size Ziploc bags. You can also place your liquids bag in your toiletry bag for easier access.
Items Not Permitted in Quart-Sized Bags
However, there are certain items you can not bring in your quart-sized bag, even if they are 3.4 ounces (100 milliliters) or less. These include:
- Gases
- Pepper spray
- Foams
- Cremes with a solid phase

Liquid Rules For Frozen Items
Frozen liquids are only permitted if they are still frozen when you reach the TSA security checkpoints. They have to be presented to TSA officers still frozen and in a clear bag.
If the frozen liquid or ice packs becomes slushy, melted, or has liquid at the bottom it must meet 3-1-1 liquid TSA approval.
If you are unsure if your frozen item will last through the security screening process you can check out TSA's official page for more information.
What Happens if Your Personal Item Doesn't Meet TSA's Limits
If you try to bring a clear quart-sized baggie filled with items that exceed 3.4 ounces (100 milliliters), the TSA will most likely confiscate those items or require additional screening.
You will need to put your quarter of a gallon of toiletries in a separate bin for them to check.
There are a few ways around this, however. You can ask the TSA officer if you can empty out your quart-sized bag and only bring the items that are 3.4 ounces (100 milliliters) or less in your carry-on luggage.
You can also put your liquid product in a checked bag, as long as they're declared and placed in a secure, tamper-evident bag.
If your checked bag happens to be over 50 lbs. you will have to pay an additional cost.
Keep in mind that even if an item is under 3.4 ounces (100 milliliters), it may still be prohibited by the TSA.
Be sure to check their website before packing any liquid cosmetics, powder-like substances, and self-defense sprays in your carry-on or checked travel bag.
How to Determine the Volume of Your Containers
When packing your quart-sized bag, it's important to make sure that all of your containers fit within the prescribed 3.4 ounce (100 milliliter) limit.
The easiest way to do this is to check the label on each container. Many travel-sized toiletries are clearly marked with their volume in ounces or milliliters.
If you're unsure about the right size of your container, you can also fill it with water and use a kitchen measuring cup to determine how many ounces or milliliters it holds.
Simply pour the water into the container until it reaches the top and then measure it with the cup.
Remember that you are only allowed one quart-sized bag per person. This bag must be placed in your carry-on bag or checked bag.
Packing Your Quart Size Bag
Now that you know what can and cannot be placed in a quart size bag, it's time to start packing! Here are a few tips to help you get started:
- Make sure all containers fit comfortably in the quart size bag with the zip closed. The bag should not be overly full or bulging.
- Pack items that are similar in nature together. For example, place all liquid items together, all gels together, etc. This will make it easier to find what you're looking for and declutter your bag.
- Place your quart size bag at the top of your carry-on bag so that it is easily accessible. This will help speed up the security process.
What Not To Use as Your Quart-Sized Bag
Quart-sized bags are a requirement to fly with a carry-on bag for any liquid container smaller than 3.4 oz. There are some bags that won't get by.
For example, a sandwich bag is too flimsy and will tear, and a gallon bag is too large.
The TSA also prohibits any bag that has been previously used to carry liquids, so make sure your bag is clean and dry before packing your liquids.
For a half-decent substitute for a quart-sized bag, try using a ziplock freezer bag. Just make sure it's clean and dry before packing your liquids.
When in doubt, it's always best to err on the side of caution and bring a quart-sized bag that meets TSA guidelines.
This will help ensure a smooth and hassle-free security experience.
