What size is a 1 Litre Ziploc bag?

The approximate dimensions of a 1L bag are 15.24 cm by 22.86 cm (6 in. by 9 in.) or 20 cm by 17.5 cm (8 in. by 7 in.).



For 2026 air travel compliance, a standard 1-Litre (1-quart) resealable plastic bag typically measures approximately 20 cm x 20 cm (7.8 inches x 7.8 inches). Some variations are slightly rectangular, such as 19.1 cm x 20.3 cm (7.5" x 8"). This size is the international limit for carrying liquids, aerosols, and gels in your carry-on luggage under the "3-1-1" rule. In 2026, security agents at major hubs like London Heathrow or Dubai are strict about the "one bag per person" rule and ensure the bag can be sealed completely; if it's overstuffed and won't zip, you may be asked to discard items. A supportive tip: many 2026 travelers have switched to "TSA-approved" reusable silicone or clear TPU bags of these dimensions, as they are more durable and eco-friendly than the disposable Ziploc versions.
