I’ve tried fabric pouches that soaked up spills and got gross. Then I switched to a makeup bag for travel plastic. Now I just wipe it clean and go. But then I had another problem: size. Too small and I can’t fit my skincare. Too big and it eats up suitcase space. So let’s answer what is the best size for a travel makeup bag once and for all.

Why I Love Plastic Makeup Bags (And You Will Too)

Plastic is waterproof. I’ve had a toner bottle leak inside—nothing soaked through. The smooth surface wipes clean in two seconds. No washing machine needed. Hard plastic cases also protect palettes from getting crushed under heavy luggage. Clear plastic ones? TSA loves them. No need to unpack at security. Plus plastic doesn’t stain like fabric. My white nylon bag looked dirty after one trip. My clear plastic one still looks new.

What Is the Best Size for a Travel Makeup Bag – My Real-World Picks

I’ve tried all three sizes over the last year. Here’s what actually works:

Mini – Fits in a purse. Holds a lipstick, concealer, and blotting sheets. Perfect for day trips or as a backup in your work bag. But too small for overnight.

Medium (my winner) – Fits weekend trips and short vacations. Holds travel-sized skincare, a small eyeshadow palette, two brushes, and sunscreen. Slides into a carry-on side pocket without bulging. This is the size I use 90% of the time.

Large – Only for long international trips or if you have a full beauty routine. Fits full-size bottles and multiple palettes. Overkill for a weekend, but great for month-long travel.

Plastic + Medium Size = Sweet Spot for Most Travelers

I settled on a medium-sized plastic bag. It’s structured so nothing gets crushed, but not bulky. Waterproof so I don’t stress about leaks. Wipes clean. And it fits in my backpack, my carry-on, and even my large tote. If you only buy one travel makeup bag, make it a medium plastic one. For quick overnights, I sometimes use a mini, but the medium handles 80% of my trips.

Not all plastic bags are made equally. Cheap ones crack or have bad zippers. If you want a durable one, check out Obeautycase with 26 years of manufacturing experience. Their plastic bags come in mini, medium, and large, and the quality shows.

My Final Advice on Size and Material

Go medium plastic for your first travel makeup bag. It’s the Goldilocks size: not too big, not too small. Plastic keeps everything safe from spills and crushes. And you’ll never go back to a smelly fabric pouch.
