✈️ Quick Answer: It depends on the type. Solid stick deodorant is NOT a liquid and has no size limit in carry-on. Gel, roll-on, spray, and aerosol deodorant ARE treated as liquids and must be 3.4oz (100ml) or less and fit in your quart bag.

Carry-On Luggage
✅ Allowed: Solid/stick deodorant: unlimited size. Gel, roll-on, spray, or aerosol: 3.4oz (100ml) max, inside your quart-sized liquids bag.
Checked Luggage

What You Need to Know
TSA classifies deodorant by its physical form, not by the word on the label. A traditional solid stick is a solid and is exempt from the 3-1-1 liquids rule, so you can bring a full-size stick in your carry-on.
Gel deodorant, roll-on deodorant, spray deodorant, and aerosol deodorant all behave like liquids at the checkpoint. They must be in containers of 3.4oz (100ml) or smaller and fit inside your single quart-sized bag.
The container's printed size is what counts, not how much product is left. A nearly empty 4oz aerosol can still be flagged because the container exceeds the limit.
For restricted medicinal and toiletry articles, each container may hold up to 0.5 kg (18 oz) or 500 ml (17 fl oz); the combined allowance is 2 kg (70 oz) or 2 L (68 fl oz) per person. Protect aerosol valves from accidental release.
Smart Packing Tips
- ✅ Switch to a solid stick or a deodorant bar to skip the quart bag entirely
- ✅ Buy a travel-size (0.5–2.6oz) gel or spray that stays within 3.4oz
- ✅ Most hotels and pharmacies abroad sell deodorant, so you can buy on arrival
💡 Pro Tip: Ordinary carry-on liquids, gels and pastes use containers up to 3.4oz (100ml) in one quart-sized bag. Medical and infant-related exceptions have separate screening procedures. See our TSA quart size bag guide to pack liquids right.
