Can I fit 10 days of clothes in a carry-on for Europe?

Yes. Summer clothes are light and compact. A 40 L carry-on bag comfortably holds 10 days of warm-weather clothing if you plan to do one laundry session at an Airbnb or laundromat mid-trip.

What size carry-on fits Ryanair, easyJet, and Wizz Air?

All three vary. Ryanair's cabin bag with Priority is 55 × 40 × 20 cm. easyJet allows 56 × 45 × 25 cm for the overhead. Wizz Air allows 55 × 40 × 23 cm. A bag at 55 × 40 × 20 cm fits all three safely.

Do I need to buy Priority Boarding on Ryanair for summer Europe trips?

Yes, unless you pack into Ryanair's small personal item (40 × 20 × 25 cm). For a 10-day trip you'll need the larger cabin bag, which requires Priority Boarding or a paid cabin bag add-on.

Should I bring a coat for Europe in summer?

A lightweight packable rain jacket is enough for most European summers. Northern Europe (Scotland, Scandinavia) can be cool in the evening — a merino cardigan or thin fleece adds little bulk and handles those nights.

Where can I do laundry during a European summer trip?

Most Airbnbs offer a washing machine — check the listing before booking. Self-service laundromats (laverie in France, Waschsalon in Germany) are common in cities and typically cost 4–8 euros for a full wash-and-dry cycle.

Carry-On Only for Europe in Summer: 10-Day Packing List

Summer is the easiest season to pack carry-on only. Light cotton and linen weigh almost nothing, shoes stay minimal, and you won't wrestle a winter coat through airport security. A 10-day trip through Europe — whether you're hitting multiple countries or based in one city — fits comfortably in a single carry-on if you pack smart and plan one laundry stop.

Why Summer Works in Your Favour

Winter travellers fight bulk. Summer travellers fight volume. Ten days of summer clothes — t-shirts, shorts, a light dress — take up far less space than five days of winter layers. The main challenges are shoes (keeping to two pairs) and toiletries (sunscreen and after-sun take up liquid allowance fast).

A 40–45 L soft-sided backpack or carry-on suitcase is the sweet spot. It meets most European budget airline overhead limits and passes through busy airport security more easily than a rigid suitcase.

The 10-Day European Summer Packing List

Clothing

5 lightweight t-shirts or tops (cotton or linen — natural fibres breathe better in heat)
2 pairs of shorts or lightweight trousers
1 casual dress or linen shirt (nice enough for dinner out)
1 light cardigan or thin long-sleeve (evenings and over-air-conditioned restaurants)
1 packable rain jacket (compresses to the size of a fist)
7 pairs of underwear (quick-dry athletic fabric dries overnight)
3 pairs of socks

Footwear (exactly 2 pairs)

Comfortable walking shoes or trainers — worn on travel day
Sandals or lightweight slip-ons — packed flat at the bottom of the bag

Two pairs of shoes is the right number for summer Europe. Walking shoes handle cobblestones and full sightseeing days. Sandals cover beach towns, casual evenings, and restaurant dinners.

Swimwear

1 swimsuit (quick-dry nylon or polyester)
1 light coverup or sarong (doubles as a scarf or beach blanket)

If you're spending more than two days near a beach or pool, pack a second swimsuit. Quick-dry fabric dries in two to three hours, but back-to-back beach days are easier with two.

Toiletries: The Summer Liquid Problem

Sunscreen, after-sun, and insect repellent all count as liquids. Plan your 1-litre bag carefully.

Sunscreen: Use a solid sunscreen stick (SPF 50 available from several brands) — no liquid restrictions apply. This is the single best swap for summer travel.
After-sun: Solid after-sun balm sticks exist and travel freely. Aloe gel in a 100 ml tube works if you count it in your liquids bag.
Deodorant: Stick or solid deodorant travels with no restrictions. Aerosol deodorant must be under 100 ml and go in the liquids bag.
Shampoo and conditioner: A shampoo bar and conditioner bar eliminate two liquid containers entirely and last weeks.

With solid alternatives, your 1-litre bag can hold just face wash, moisturiser with SPF, and a few other small items — leaving room to pick up a local product without stress.

Budget Airline Strategy: Ryanair, easyJet, Wizz Air

These three carriers dominate European short-haul routes and all charge for carry-on overhead access beyond a personal item.

Ryanair: Without Priority Boarding, you're limited to one small bag (40 × 20 × 25 cm) under the seat. For a 10-day trip you need the larger cabin bag (55 × 40 × 20 cm) — add Priority or a cabin bag fee at booking. Adding it during booking is always cheaper than at the airport.

easyJet: A cabin bag up to 56 × 45 × 25 cm is included with Flexi or PLUS fares. On the cheapest Standard fare, you pay extra for overhead access. If you're travelling light into their 45 × 36 × 20 cm personal item size, it's free — but that's very tight for 10 days.

Wizz Air: Free underseat item at 40 × 30 × 20 cm on base fares. Cabin bag (55 × 40 × 23 cm) requires a paid upgrade. If flying multiple Wizz Air legs on a single trip, add the bag allowance to all legs at once — it's cheaper.

Laundry: The 10-Day Carry-On Secret

One mid-trip laundry session makes 10 days in carry-on easy. Pack 5–6 days of clothes, wash them halfway through, and the second half of the trip is covered. Airbnbs with a washing machine are common — filter for this when searching. If staying in hotels, find a self-service laundromat nearby; most European city centres have one within walking distance.

Quick-dry fabrics make sink washing viable for socks and underwear. A small travel clothesline (costs under £5, weighs nothing) lets you hang items across a hotel bathroom overnight.

What Makes Summer Easier Than Winter

The bulk difference is stark. A wool winter coat weighs 1–2 kg and fills half a carry-on by itself. Ten days of summer clothing — tops, shorts, a light jacket — weighs under 3 kg total and leaves room to spare. You can afford to bring one item you might not use without sacrificing space. Winter travellers rarely have that luxury.
