What size is a medium Ziploc bag?

Amazon.com: Ziploc Medium Quart Size (6.96 x7. 40) Freezer Storage Bags Easy Open Tabs - 180 Bags, 3 PK x 60 Bags : Health & Household.



A standard "Medium" Ziploc storage or freezer bag typically measures 7 inches by 7-3/8 inches (approx. 17.7 cm x 18.8 cm). In 2026, these bags remain the industry standard for the "Quart" size, which is a crucial measurement for travelers following the "3-1-1" liquids rule at airport security. These bags have a capacity of roughly 946 ml, making them perfectly sized for holding multiple 100 ml travel containers. Modern versions often feature the "Grip 'n Seal" technology with extended tabs for easier opening. For those using them for food prep, the freezer-grade variety is slightly thicker than the standard storage bag to prevent freezer burn. If you are packing for a flight, ensure the bag is clear and can be fully sealed; a bag that is bursting at the seams or cannot close may be rejected by TSA or international security agents during the screening process.
