How do you know if a bag is quart-size?

The approximate dimensions of a quart-size bag are 7? x 8?. The TSA prefers it to be made of clear plastic, like EzPacking's Extra Small Cube, so the items can be easily inspected at a glance, without having to open the pouch.



To ensure a bag meets the TSA's "quart-size" requirement in 2026, you should look for dimensions of approximately 6 inches by 9 inches (15cm x 22cm). A standard "Zip-top" sandwich bag is usually slightly smaller than a quart, while a freezer-grade quart bag is the exact benchmark. If you are using a reusable toiletry kit, you can verify the volume by checking if it holds roughly 0.95 liters (32 fluid ounces). A common "pro-tip" for 2026 travelers is to avoid over-stuffing; TSA officers generally use a "visual test" rather than a ruler, so if the bag is bulging and cannot seal easily, it will likely be flagged. If you're unsure, remember the "3-1-1" rule: 3.4oz containers, in 1 quart-sized bag, 1 bag per passenger. If the bag fits comfortably in your hand and zips shut without tension, you are typically safe.
