When choosing a travel bag, the capacity determines the experience. Is 45L enough for a trip to Europe? This article will combine airline standards, actual user feedback, and introduce our solutions as a professional travel bag manufacturer to help you quickly determine the most suitable option.

Ⅰ. Can a 45L capacity meet the needs of a trip to Europe?
For most European travelers, a 45L travel bag is considered a lightweight option. According to the International Air Transport Association (IATA) recommendations, the size limit for carry-on luggage is approximately 55×40×20cm, equivalent to approximately 40-45L capacity, and the weight is usually 7-15kg (depending on airline policy).
Short trips (3-5 days): 45L is enough, suitable for carrying 3-5 sets of clothing, toiletries, and necessary electronic devices.
Medium and long-distance trips (more than 7 days): If you only bring a 45L bag, you need to pack it very simply, or pair it with a personal handbag.
According to the official websites of airlines such as easyJet, Ryanair, and Lufthansa, 45L meets the standards of most cabin luggage. As long as it is not overweight and avoids bulging, it can be boarded directly.
Ⅱ. Advantages and challenges of choosing 45L for European travel
Advantages
- ✅ Free check-in, saving costs: European low-cost airlines have high baggage check-in fees, and a 45L travel backpack can save €30-60 in check-in fees.
- ✅ Flexible movement: Lightweight, suitable for city shuttles and train transfers, without having to wait for luggage carousels.
- ✅ Environmental protection concept: Small capacity promotes simplified packing, which is in line with the trend of green travel.
Challenges
- ⚠️ Winter travel is stressful: thick clothes take up space, and it is recommended to use compression storage bags.
- ⚠️ Insufficient shopping space: In Europe’s shopping paradise, 45L is difficult to accommodate extra loot.
- ⚠️ Pay attention to differences in airline policies: low-cost airlines have smaller requirements for free carry-on sizes, and 45L may require a paid upgrade.

✔ Rolling method: Save space and reduce wrinkles, especially suitable for T-shirts and jeans.
✔ Compression bag essential: Travel in winter or bring down jackets, compression bags can reduce space by 50%.
✔ Carry-on small bag: Put passports, wallets, headphones, etc., in a carry-on handbag to avoid frequent opening of the main bag.
V. Conclusion: Is 45L enough?
- Short trip (3-5 days): ✔️ Completely sufficient, especially for light travelers.
- Medium and long distance (7-14 days): ✔️ Feasible, but you need to pack minimally or carry an additional foldable travel hand bag.
- Luxury shopping + winter travel: ❌ It is recommended to check in extra luggage or choose a 55-60L travel bag.
If you plan to travel in Europe, a 45L outdoor backpack + a folding travel bag is the most cost-effective combination.
