what size deodorant can you take on a plane

You can bring deodorant on a plane, but the size you’re allowed depends on the type of deodorant and whether it’s in your carry-on or checked bag.

Quick Scoop

  • Solid stick deodorant: Any size is fine in your carry-on or checked luggage because it’s treated like a solid, not a liquid.
  • Liquid, gel, roll-on, cream, or spray deodorant in carry-on: The container must be no more than 3.4 oz / 100 ml , and it has to fit inside your single quart-sized clear liquids bag (the usual “3-1-1” rule).
  • In checked baggage: Bigger sizes are allowed, but aerosol toiletries (like spray deodorant) are generally limited to about 18 oz (500 ml) per container and 70 oz (2 L) total per person by aviation safety rules.

What size deodorant can you take on a plane?

For your carry-on bag

  1. Solid stick deodorant
    • No specific size limit.
    • You can pack a full-size stick in your personal item or cabin bag without putting it in the liquids bag.
  1. Liquid / gel / roll-on / cream / spray deodorant
    • The container must be 3.4 oz (100 ml) or smaller.
 * All of your liquids, gels, creams, pastes, and aerosols must fit together in **one quart-sized, clear, resealable bag**.
 * A half-empty 6 oz bottle still counts as 6 oz, so it won’t be allowed through security.

For your checked bag

  • You can usually bring larger deodorants , including big aerosols, in checked luggage.
  • For aerosols like spray deodorant, aviation rules typically cap them at 18 oz (500 ml) per container and 70 oz (2 L) total per passenger for toiletry items.
  • Containers need a cap or protective lid so they don’t discharge accidentally in the hold.

Quick examples

  • A 2.6 oz stick deodorant in your backpack: OK, and doesn’t need to go in the liquids bag.
  • A 3 oz travel spray or roll‑on in your carry-on: OK, as long as it’s in your quart-sized liquids bag.
  • A 5 oz spray can : Not allowed in carry-on, but generally fine in checked baggage within the aerosol limits.

Forum-style tip roundup

“If it’s a solid , don’t overthink the size. If it slosh­es , squeezes , or sprays , keep it at 3.4 oz/100 ml or less for carry-on, or toss it in checked.”

A simple way to decide:

  • Ask yourself if your deodorant is solid or liquid/gel/spray.
  • Solid = no size worries in cabin.
  • Not solid = 3.4 oz / 100 ml max in carry-on, or just move the larger one to checked.

TL;DR:

  • Carry-on: stick of any size, liquids/gels/sprays up to 3.4 oz (100 ml) in the quart bag.
  • Checked: bigger sizes allowed; aerosols usually limited to 18 oz per container and 70 oz total per person.
