What size clear bag can you take to the airport?

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.



In 2026, the global standard for carry-on liquids remains the "3-1-1" rule, which dictates that you can carry one clear, resealable plastic bag with a volume of approximately one quart (or one liter). The physical dimensions typically recommended by the TSA and international agencies are roughly 8 inches by 8 inches (20cm x 20cm). Every individual liquid, gel, or aerosol container inside must be 3.4 ounces (100ml) or less. However, at certain major hubs like London Heathrow and several European airports, the installation of advanced CT scanners has allowed for a transition to a 2-liter limit, often removing the requirement for a separate clear bag entirely. Despite these technological upgrades, the quart-sized bag remains the safest "universal" standard for international travelers, as many secondary airports still lack the equipment to process liquids outside of these strict, transparent containers.
