How to Pack Light for a Family Trip to Europe (The 3-Day Rule)

We're a family of five. We travel to Europe for 4-6 weeks every summer. And we use one medium suitcase for the whole family. People think I'm kidding. I'm not.

The secret isn't some magical compression hack or vacuum bags. It's a mindset shift. Once you stop packing for every possible scenario and start packing for how you'll actually live, everything changes.

The 3-Day Rule

Here's the method: pack 3 days of clothes per person. That's it. You'll do laundry. Every Airbnb has a washer, every city has a laundromat. Once you accept that laundry is part of travel, packing becomes radically simple.

Three days of clothes means you're always wearing one outfit, one is drying, and one is clean and ready. It's a rotation. It works. We've done it across four summers and multiple countries.

What We Actually Pack (Per Person)

• 3 tops
• 3 bottoms (shorts or pants depending on climate)
• 1 swimsuit
• 5 underwear, 3 pairs of socks
• 1 outfit worn on the plane (layer it — this doesn't count toward your 3 days)
• 1 jacket or fleece
• 2 pairs of shoes (walking shoes + sandals)
• 1 hat, 1 pair of sunglasses

That's it. For three kids and two adults, this all fits in one medium checked suitcase with room to spare.

What We DON'T Pack

• Toiletries — buy them there. European pharmacies are amazing, well-stocked, and often cheaper than what you'd buy at home. Plus you avoid the whole liquids-in-a-bag airport hassle.
• Sunscreen — they have it everywhere, and European sunscreens are often better formulated (they use filters that aren't approved in the US yet).
• Diapers — available at every supermarket in every European city. No need to haul a box across the Atlantic.
• "Just in case" items — if you're packing something "just in case," don't. You won't need it. And if you do, you can buy it.
• Books — use a Kindle or library apps like Libby. Physical books are heavy.
• Excessive toys — each kid gets one small item. They'll be too busy at camp and exploring to miss the rest.

What You Can't Replace Easily

Some things are worth packing because they're hard to find or replace abroad:

• Broken-in walking shoes — new shoes + cobblestone streets = blisters. Wear shoes that are already comfortable.
• Your kid's comfort item — that specific stuffed animal or blanket. Don't leave it behind. Don't risk it.
• Specific medication — bring what you need with prescriptions. European pharmacies are great but may not carry your exact brand or formulation.
• A good quality sunhat — European sun hats tend to be fashion-first, function-second. Bring one that actually provides coverage.
• A reliable portable charger — you'll be out all day. Phones die. A good charger is worth the weight.

The Suitcase Setup

We use one medium checked bag. I also bring a personal item backpack. Each kid carries a small backpack with a change of clothes, snacks, and their comfort item. That's our entire luggage situation.

Total: 1 checked bag + 4-5 personal items.

No overhead bin drama. No lost luggage panic (the essentials are in the backpacks). No hauling multiple suitcases through train stations.

Packing Tips That Actually Help

• Roll, don't fold. Rolling saves space and reduces wrinkles. This isn't a myth — it genuinely works.
• Packing cubes are life-changing. One cube per person. Pull out the cube, grab what you need, put it back. No digging through a chaotic suitcase.
• Dark colors hide stains. This matters when you're traveling with kids who eat gelato daily.
• Layer for the plane. Airports are freezing, planes are hot — or vice versa. Wear your bulkiest items and layer so you can adjust.
• Ship bulky items ahead if you need to. If camp requires specific gear (soccer cleats, a wetsuit), consider shipping it to your accommodation rather than packing it.
