The best toiletry bag size depends on your trip length and TSA requirements, but a medium-sized bag (8-10 inches) works for most travelers.

Different sizes serve different travel needs:

• Small toiletry bags (6-8 inches) – Perfect for weekend trips and carry-on compliance with TSA's 3-1-1 rule (liquids in 3.4 oz containers in a quart-sized bag). Our Small Cosmetic Pouch is ideal for quick getaways.

• Medium toiletry bags (8-10 inches) – Ideal for week-long trips, fitting full-sized products while remaining compact enough for luggage. The Essentials Toiletry Bag offers the perfect balance of space and portability.

• Large toiletry bags (10+ inches) – Best for extended travel or checked luggage when you need full-sized products and multiple compartments. Our Dopp Kit or Cosmetic Case provides maximum organization for longer adventures.

Small toiletry bags keep you TSA-compliant and organized for short trips, while medium and large options accommodate more products for longer stays. The best travel toiletry bags feature waterproof materials to prevent spills, multiple compartments for organization, and a hook for hanging in tight bathroom spaces. At BEIS, our cosmetic cases and toiletry bags are designed with smart organization and water-resistant materials to keep your essentials secure and accessible wherever you travel.
