When preparing for a trip to Korea, one common concern is the capacity of your suitcase. Many people wonder if a carry-on size is sufficient for a 2-night, 3-day trip, or if a larger one is better if they plan to buy cosmetics and clothes.
For a trip to Korea, you need to consider not only the number of nights but also the amount of shopping you'll do locally, your mode of transportation, and the baggage regulations of the airline you're using.
In this article, the New Trip editorial team explains the necessary suitcase capacity for a trip to Korea, primarily focusing on 2-night, 3-day and 3-night, 4-day trips, and how to choose one without fail.
For a trip to Korea, the basic guideline for capacity is 30-40L for a 2-night, 3-day trip, and 40-60L for a 3-night, 4-day trip. However, if you plan to buy cosmetics or clothes, consider a slightly larger size or a model with an expansion feature.
| Trip Duration | Estimated Capacity | Size | Recommended Travel Style |
|---|---|---|---|
| 2 nights, 3 days | 30-40L | S size | Sightseeing-focused, light luggage |
| 3 nights, 4 days | 40-60L | S-M size | Sightseeing + Shopping |
| 5 nights or more | 60L or more | M-L size | Long stay, family trip |
For a 2-night, 3-day trip, a carry-on size model of about 30-40L (S size) is generally sufficient. If you choose light clothing and decant skincare products into smaller containers, you can pack compactly. However, in addition to size, you also need to check the weight limit set by the airline.
On the other hand, if you plan to buy a lot of cosmetics, clothes, or food, an M size or an S size with an expansion feature would be good options even for a 2-night, 3-day trip.
For a 3-night, 4-day trip, an S-M size of about 40-60L is recommended. This provides enough space for clothes and toiletries, plus room for souvenirs on the way back.
If you're primarily sightseeing and have light luggage, a larger S size is good; if you want to enjoy shopping, an M size offers more peace of mind. When departing, try to keep the suitcase about 70-80% full, leaving some empty space.
For 5 nights or more, an M-L size of 60L or more is a good guideline. If you need to pack seasonal clothing, shoes, or luggage for the whole family, even more space will be necessary.
However, larger suitcases also have a heavier body weight. If you plan to travel a lot by subway or on foot, consider using one M size suitcase and a smaller bag instead of one large L size suitcase.

For a trip to Korea, it's important to anticipate increased luggage due to shopping and travel between the airport, subway, and hotel. Don't decide solely on capacity; check the following four points:
When traveling to Korea, it's common to buy cosmetics, clothes, food, and miscellaneous goods, leading to more luggage on the way back.
If you plan to shop, it's crucial not to pack your suitcase to full capacity when you depart. Even for a 2-night, 3-day trip, if shopping is your focus, choosing an M size or a model with an expansion feature will ensure you have enough room.
In Korea, you'll likely travel by airport railroad, subway, and on foot. Considering transfers and getting to your hotel, a lighter suitcase is easier to handle.
A guideline is under 3kg for S size and under 4kg for M size. A lighter body allows more leeway with airline weight limits.
When returning with more luggage, the performance of the casters greatly affects the comfort of your journey.
Double casters or 360-degree rotating types make it easier to change direction in crowded station or airport passages. If you'll be moving around your hotel late at night or early in the morning, check for quietness.
On trains or sloping surfaces, a caster stopper that prevents the suitcase from moving is also convenient.
The size and weight limits for carry-on and checked baggage vary depending on the airline and fare plan. Especially with LCCs, the free baggage allowance might be strictly limited, or checked baggage might incur a fee.
An "S size" suitcase does not necessarily mean it can always be carried on. After booking, compare your suitcase's external dimensions and body weight with the regulations of your flight.

An S size of about 30-40L is a good estimate.

If you have light luggage for a 1-2 night trip, a backpack or duffel bag alone might be enough.
However, since souvenirs might increase on the way back, it's a good idea to bring a foldable bag just in case.
