I’ve packed for Europe wrong at least four times. Not catastrophically wrong — I always had clothes, I always had shoes — but wrong in the way where you’re dragging a rolling bag through cobblestone streets at 8 AM wondering why you thought you needed six shirts for seven days, or standing at a Ryanair gate listening to a gate agent tell you your bag doesn’t fit and watching your budget evaporate in real time.
The last time I did a two-week Europe trip with just a carry-on, everything changed. I remember it because I got to the airport and for the first time in years I just… walked to the gate. No checking in baggage. No waiting at carousels. No standing there watching the same bag come out twice before yours finally appears. Just walked to the gate and got on the plane. That feeling was honestly better than I expected.
But getting there — getting to a point where two weeks of clothes actually fit into one bag without looking like you’re wearing the same thing every day — took some real trial and error. Here’s what actually works, and what I kept getting wrong before I figured it out.
Before You Start Packing
- Make a list first. I know that sounds boring. Do it anyway.
- If you’re American, check the carry-on size for every airline in your trip, not just the first one. Budget carriers in Europe are stricter than U.S. domestic flights and they are not interested in exceptions.
- Don’t pack for the hypothetical version of the trip. Pack for what you’ll actually do.
- Lay everything out and then put half of it back. That’s not a joke.
- Check the weather for every city on your itinerary, not just the first one.
- I once packed three “dinner” outfits for a trip where I ended up eating in casual places every night. Don’t be me.
- Give yourself a packing day, not a packing hour.
- Shoes are where trips fall apart. Figure those out first.
The Carry-On Situation in 2026
The rules haven’t changed dramatically, but enforcement has tightened on some carriers. If you’re flying transatlantic on Delta, United, or American, you’re generally fine with a standard carry-on up to 22x14x9 inches plus a personal item. Once you get to European budget airlines — Ryanair, Wizz Air, EasyJet — things get significantly more complicated.
Ryanair currently charges for anything larger than a small personal bag unless you’ve paid for priority boarding or a specific fare tier. That caught me off-guard once. I thought I was prepared and then realized my “carry-on” was only free if I’d paid extra. I hadn’t. The fee at the gate was not enjoyable.
The smarter move is to check every carrier’s current policy about a week before travel, because they update these things more often than they should. What was true six months ago may not be true now.
A guy named Tom on r/onebag put it well in a thread I read: “The bag isn’t the problem. The rules aren’t even the problem. The problem is assuming yesterday’s rules are today’s rules.” That’s the thing.
What Actually Fits in a Two-Week Carry-On
Here’s what I’ve landed on after way too many experiments.
Clothing for two weeks in a 40-liter bag:
- Five to six tops that work both casually and for nicer evenings depending on what you pair them with
- Three bottoms: two pairs of trousers or jeans plus one that’s lighter for warmer days
- One dress or smart shirt that handles the fancier meals
- One lightweight jacket that can layer over everything
- Seven pairs of socks and underwear — you can do laundry once
- One swimsuit if you’re going anywhere coastal
- Pajamas or something comfortable that doubles as loungewear
Shoes:
- One pair of walking shoes that look decent enough for restaurants
- One pair of sandals or something lighter
- That’s it. Two pairs. No more.
The key thing I figured out late — embarrassingly late — is that the bag fills up with shoes and toiletries more than with clothes. Get those two categories right and the rest almost solves itself.
Toiletries Without Losing Your Mind
TSA’s 3-1-1 rule still applies for U.S. departures: liquids in containers of 3.4 ounces or less, all in one clear quart-sized bag. The EU has recently been enforcing similar rules more strictly at security, so don’t assume you can buy something at the departure airport and carry it straight through. I learned that with a bottle of expensive moisturizer I was hoping to bring without checking. Gone.
The simplest solution is moving as many toiletries as possible to solid formats. Solid shampoo bars, solid conditioner, sunscreen sticks, solid deodorant. None of them count toward the liquid limit. All of them travel well. It took me embarrassingly long to commit to this fully, but now I wouldn’t go back.
For anything you can’t replace with a solid, buy it small or buy it there. European pharmacies are excellent and considerably less stressful than security stress.
Mid-Trip Laundry Is the Real Secret
This is the part most packing guides mention briefly and move on from, but it’s actually the most important variable. If you do laundry once during a two-week trip, you essentially have access to your full wardrobe twice. That’s the whole trick.
Most European cities have laundromats that are easy to use and not particularly expensive. Some hotels have guest laundry facilities. Some Airbnbs have machines available. It takes maybe two hours including wash and dry time, and it means you don’t need to overpack at the start.
I used to feel weird about mid-trip laundry for some reason. Like it was admitting defeat. Now I think people who don’t do it are just carrying extra weight for no good reason.
What I’d Do Differently
I’d stop packing “just in case” items. Every single trip, I bring something for a scenario that never happens. It goes home unworn. Every time. I know this and I still do it. This is the year I stop.
I’d also sort out the shoe situation before anything else. I once packed the rest of the bag perfectly and then tried to squeeze in a second pair of boots and ruined everything. Shoes first. Always.
And I’d use a packing cube system earlier. Not for everything, but for keeping categories separate. It sounds fussier than it is, and it makes unpacking at hotels so much faster it’s almost worth doing for that alone.
FAQ
What’s the best carry-on bag for Europe?
Something around 40 liters that fits within most airline size limits. I like bags with a clamshell opening — makes accessing things at security much easier.
Can I really do two weeks on one carry-on?
Yes. I’ve done it multiple times now. The key is committing to it before you start packing, not after.
What about rainy weather?
A packable rain jacket. It compresses small and handles almost every weather scenario.
How strict are European budget airlines?
Very. More than most Americans expect.
Is laundry mid-trip worth it?
Absolutely. It changes everything.
What toiletries are essential?
Solid shampoo, deodorant, sunscreen stick, and a small first aid kit. Buy the rest there.
Conclusion
Packing light for two weeks in Europe felt like a discipline problem for years. Like I just needed more willpower or a better system or the right bag. But it turned out to be simpler than that. Once I stopped packing for hypothetical scenarios and started packing for what I’d actually do, the whole thing got easier.
You don’t need every option. You need the right ones. That’s a smaller list than most people think, and traveling with it is noticeably, genuinely better.
