what size lotion can you take on a plane

You can take lotion on a plane in your carry-on as long as each container is no larger than 3.4 ounces (100 milliliters) and all your liquids fit in a single quart-sized, clear, resealable bag.

Quick Scoop

• Maximum size in carry-on: 3.4 oz / 100 ml per lotion bottle (container size, not how much is left inside).

• All liquids, gels, and creams (including lotion, moisturizer, sunscreen, liquid makeup) must fit together in one quart-sized clear bag per person.

• A 4 oz bottle is not allowed in carry-on even if it’s half empty, because security goes by the printed container capacity.

• In checked luggage, there is no TSA size limit for lotion bottles, as long as they’re packed safely to avoid leaks.

• This is part of the TSA “3-1-1” liquids rule that’s still in effect in 2026 for U.S. flights and widely mirrored on many international routes.

Simple rule of thumb

• Travel with lotion in your carry-on → use 3.4 oz (100 ml) or smaller, in the liquids bag.
• Want to bring your big full-size lotion (8–12 oz, pump bottles, etc.) → put it in your checked bag.

If you’re ever unsure, imagine security looking only at the number printed on the bottle. If it says over 3.4 oz / 100 ml, don’t put it in your carry- on.
