A quart-sized bag is typically about 7 x 8 inches (or roughly 18cm x 20cm), holding one quart (32 oz or nearly a liter) of liquid, designed to fit the TSA's 3-1-1 rule for carry-on liquids, though some slight variations exist for different brands like 6.5"x7.5" or 6"x9" (with gusset).
TSA enforcement on quart-size bags is rigorous: officers will reject any bag that exceeds the one-quart volume, isn't fully clear, or contains containers larger than 3.4 oz. Opaque or oversized bags, overfilled pouches, and extra liquid items trigger secondary screening and potential confiscation.

Here's a copy of TSA regulations about what you can and can't put in your carry on before you go through security. Basically, any liquids (water), aerosols, gels, creams and pastes (the peanut butter on crackers) must be in a 3.4 ounce or less container. All of the containers have to be in a 1 quart, clear ziplock bag.
Sandwich bags typically measure about 6.5 inches by 5.8 inches (around 16.5 cm by 14.7 cm). Quart bags are larger, usually around 7 inches by 8 inches (about 17.8 cm by 20.3 cm), giving more space to fit bulkier items.
You are allowed to bring a quart-sized bag of liquids, aerosols, gels, creams and pastes in your 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.
Depending on the TSA agent, they might make you throw stuff away if it doesn't fit. Use a quart size and fold it in half and pray for the best. Otherwise just get travel size containers to avoid any issues. It's a lot less hassle to just check one bag.
You are allowed to bring a quart-sized bag of liquids, aerosols, gels, creams and pastes through the checkpoint. These are limited to 3.4 ounces (100 milliliters) or less per item. This is also known as the 3-1-1 liquids rule.
CAA Regulations For Nail Clippers
Similar to the TSA regulations, nail clippers are allowed in both carry-on and checked baggage. Along with disposable razors and tweezers, nail clippers are safe to pack in a personal item bag.
Each passenger can carry liquids, gels, aerosols, creams, and pastes up to 3.4 ounces, or 100 milliliters, per container. These must be in a single, clear, quart-sized, zip-top bag. This is where a clear toiletry bag becomes essential. It not only meets TSA requirements but also simplifies the security process.
If you travel by air frequently,do you know how big is a quart size bag? A TSA-approved quart-sized bag typically measurements around 7 x 8 inches (17.8 x 20.3 cm). This size allows for maximum capacity while ensuring it fits the requirements set by the TSA.
If the airport asks you to put liquids in a separate bag: containers must be in a single, transparent, resealable plastic bag, which holds no more than a litre and measures approximately 20cm x 20cm. contents must fit comfortably inside the bag so it can be sealed.
The Ziploc XL Sandwich Bags with Easy Guide Closure are my go-to. They're super durable—no splitting or tearing—and the XL size fits way more than just sandwiches (wraps, snacks, even random stuff like toiletries when I travel).
Any liquids in your hand luggage must follow these rules: All liquids, gels and aerosols must be under 100ml each. Liquids under 100ml no longer need to be in plastic bag and can be left in your hand luggage. Liquids, Aerosols and Gels greater than 100ml are not permitted.
Does deodorant count as liquid? Spray, gel, and liquid deodorants count as liquids. If you're packing them in your carry-on, they must be packed in a clear quart-sized bag and be 3.4 ounces or less.
Understanding the TSA's 3-1-1 rule
The TSA's 3-1-1 rule allows passengers to bring 3.4-ounce containers of liquids, gels, and aerosols in a single, clear quart-sized bag. This rule applies to travel-sized containers of everyday hygiene items like shampoo, conditioner, lotion, or toothpaste tubes.
You can't bring sharp items (knives, scissors over 6cm), many tools (hammers, saws), firearms, flammable liquids/gases, corrosive chemicals (bleach, oven cleaner), explosives, pepper spray/mace, large lithium batteries, and items that look like weapons on a plane carry-on. Restricted liquids (over 100ml), certain powders (over 350ml/g), and some electronics like hoverboards also face limitations or bans.
If packed in carry-on, they must be less than 4 inches from the pivot point. Any sharp objects in checked bags should be sheathed or securely wrapped to prevent injury to baggage handlers and inspectors.
You can't pack explosives, firearms (unless declared and packed correctly), flammable liquids/solids (like gasoline, lighter fluid, large aerosols), strong acids/bleach, disabling sprays (pepper spray), large quantities of alcohol (>70% ABV), spare lithium batteries, or hoverboards in checked luggage due to safety risks; instead, keep essentials like medication, electronics, and valuables in your carry-on.
As per the guidelines, all carry-on liquids, gels, and aerosols must be in containers of 3.4 oz (100ml) or less, packed in one clear quart-size bag.
Always put your chargers and spare batteries in your carry-on before you head to the airport.
The Transportation Security Administration (TSA) doesn't ask you to keep your medicines in their original prescription bottles. But each state may have its own rules. If you aren't bringing your medicine in its original bottle, bring a copy of the prescription or a letter from your doctor.
Spray, gel, or liquid roll-ons need to follow the TSA's 3-1-1 rule for carry-on bags, meaning they should be in containers of 3.4 ounces or less and fit in one quart-sized bag. Solid stick deodorants have no restrictions, so you can pack them freely in your carry-on or checked luggage.
A sandwich bag is relatively smaller than a quart-size bag, at least in the US. To be more specific, its dimensions are 6.5” x 5.5”. The most popular brand people use is Ziploc; a household name in most families. They're usually used to hold a sandwich or any small snacks for kids to take to school.
Each container must be 3.4 ounces (100 milliliters) or less per item. If you aren't able to stay within those limitations, remember that full-size toiletries can always be purchased upon arriving to your destination - don't inconvenience yourself and waste money by checking a bag if you don't have to!
