Carry-On Toiletry Bag Size Guide

Security limits for cabin liquids can differ by airport and may change as screening equipment is introduced. Always check official departure, connection and airline guidance shortly before travel rather than relying on the bag label alone.

Separate container and bag limits

Rules may restrict the volume of each container and require all liquids, gels, creams, pastes and aerosols to fit in one transparent resealable bag. A half-full oversized bottle may still be treated according to its marked capacity.

Choose a compliant, usable bag

Select a clear bag that closes without stretching and fits the dimensions stated by the relevant authority. A sturdy zipper and reinforced seams help with reuse, but decorative multi-compartment organisers may not satisfy a single-bag requirement.

Reduce liquid volume

Use correctly labelled travel containers where permitted and take only the amount needed. Solid toiletries can reduce liquids, although security staff decide how an item is classified. Keep medicines and infant supplies accessible with required documentation.

Prevent leaks

Close caps firmly, release excess air from soft bottles and place likely leaks in an additional permitted pouch where appropriate. Do not decant products that can react with an unsuitable container.

Pack for screening

Keep the bag easy to remove if required. Check rules again for connecting airports and the return journey; duty-free liquids and aerosols can have separate conditions.
