In short
A travel bag is lighter, more flexible and fits into any boot. It's ideal for weekends, road trips and tours with changing accommodation. A suitcase protects its contents better, keeps clothing in shape and rolls comfortably over long distances. It's the better choice for flights with checked luggage and longer holidays. In between sits the wheeled travel bag.
Which piece of luggage suits you depends less on looks than on your trip: how do you arrive, how far do you carry or pull your luggage, and how fragile is what you're bringing? Here you'll find a direct comparison, suitable models for typical trips and the right size for weekends and holidays.
Travel bag or suitcase: the comparison at a glance
| Criterion | Travel bag | Suitcase |
|---|---|---|
| Empty weight | usually lighter, more reserve for free baggage allowance | heavier due to shell, frame and wheels |
| Protection for contents | low, impacts and pressure pass through | high, especially with hard shell |
| Transport | carried by handles, shoulder strap or backpack straps | rolls across airports, platforms and tarmac |
| Space in the car | adapts to any gap | fixed shape, stacks well |
| Order when packing | one large main compartment, packing cubes help | two halves, packing straps and dividers |
| Cobblestones, stairs, snow | independent of surface | wheels reach their limits |
| Storage at home | foldable or stored flat | needs a fixed spot |
The differences between hard shell and fabric suitcases are explained in our guide Hard shell or fabric.
Which luggage for which trip?
Weekend trip
30 to 45 l
Two or three outfits, toiletries and a pair of shoes. A travel bag is quickly packed and fits under any seat on the train or on the back seat.
ThuleThule Chasm 30L30 l, can also be carried as a backpack
Flight with carry-on only
up to approx. 40 l
On long walks through the terminal, a cabin trolley is more comfortable. Check your airline's size limits and look for a low empty weight.
TITANTITAN UPGRADE38 l, 55 x 40 x 20 cm, TSA lock
Road trip, train, touring holiday
50 to 70 l
A large, soft bag fills the boot without leaving empty gaps. With backpack straps you stay mobile on platforms and stairs too.
The North FaceThe North Face Base Camp Duffel M 7171 l, water-repellent, can be carried as a backpack
Holiday with checked luggage
60 to 110 l
Things get rough on the baggage carousel. A solid shell protects clothing, souvenirs and electronics, while the wheels carry the weight.

You'll find more choice among the travel bags and the suitcases and trolleys.
Travel bag: strengths and weaknesses
The travel bag is the more flexible piece of luggage. It has no fixed shape, so it fits into overhead bins, boots and cupboards where a suitcase would find no room. Empty, it can be folded or stored flat.
- Lightweight: Without a shell and wheels, an empty bag usually weighs noticeably less than a suitcase of the same size. That's extra allowance for souvenirs if your airline charges by weight.
- Versatile: Many models can be carried as a backpack via stowable shoulder straps, handy on cobblestones, stairs and in snow.
- Less protection: Pressure from outside goes straight through to the contents. Pack fragile items in the middle, surrounded by soft clothing.
- Carrying instead of rolling: Packed heavy, a bag without wheels becomes tiring over long distances. A wheeled travel bag helps here.

For a wider choice: travel bags without wheels, compact weekenders and cabin bags.
Suitcase: strengths and weaknesses
The suitcase shows its strengths on flights and long journeys. Packed clothing keeps its shape, and with four wheels you can push even heavy luggage effortlessly beside you.
- Protection: A hard shell suitcase protects against impacts, pressure and rain. For electronics, bottles and delicate clothing, it's the safer choice.
- Organisation: Two halves with packing straps and a divider keep clothing separated, and many models also have mesh pockets.
- Comfort: A telescopic handle and wheels take the carrying off your hands. Four wheels let the suitcase roll upright beside you.
- Fixed size: A suitcase needs its own space, even empty in the cupboard. Expandable models gain a few extra litres via a zip.
A good middle ground is a fabric suitcase from the soft luggage range: it has wheels and a frame like a suitcase, but is often lighter and has outer pockets for quick access.

Empty weight compared
How much luggage weighs when empty matters especially with budget airlines and weight limits for checked baggage. These examples show the difference at a similar volume:
| Model | Type | Volume | Empty weight |
|---|---|---|---|
| Thule Chasm 30L | Travel bag without wheels | 30 l | 1.2 kg |
| Deuter Duffel Pro 40 | Travel bag with backpack straps | 40 l | 1.2 kg |

| The North Face Base Camp Duffel M | Travel bag without wheels | 71 l | 1.59 kg |
| Deuter Duffel Pro Movo 60 | Wheeled travel bag | 60 l | 3.32 kg |
| Travelite Briize M | Fabric suitcase, 4 wheels | 62 l | 3.2 kg |
| Travelite Air Base M | Hard shell suitcase, 4 wheels | 71 l | 3.2 kg |

Which size for how many days?
Whether bag or suitcase: the litre capacity depends on trip duration and packing style. If you can do laundry along the way, volume hardly needs to grow with the length of your trip.
| Trip duration | Volume | suits well |
|---|---|---|
| Weekend, 1 to 3 days | 30 to 45 l | travel bag, cabin trolley |
| Short break, 4 to 7 days | 50 to 70 l | large travel bag, medium suitcase |
| Holiday, 1 to 2 weeks | 70 to 110 l | large suitcase, wheeled travel bag |
| 3 weeks or more | over 110 l | XL suitcase or two pieces of luggage |
Guideline values. All suitcase sizes with centimetres and litres are shown in our guide Suitcase sizes at a glance.
Frequently asked questions: travel bag or suitcase
Is a travel bag or a suitcase better for a flight?
If you're only flying with carry-on, either works: a cabin trolley rolls comfortably through long terminals, while a soft travel bag adapts to the overhead bin and weighs less when empty. As checked luggage, a hard shell suitcase better protects the contents from impacts and pressure on the baggage carousel.
How big should a travel bag be for a week?
For a week, 50 to 70 litres is a good guideline. If you pack light and can do laundry along the way, 40 to 50 litres will be enough. For a weekend, 30 to 45 litres is plenty.
Travel bag or suitcase in the car: which fits better?
In a small boot, the travel bag has the advantage, as it moulds itself into gaps and around other luggage. With several people and a large boot, suitcases with a fixed shape stack better, and delicate items are protected from pressure inside them.
Can I take a travel bag as carry-on?
Yes, as long as it meets your airline's size and weight limits. Many airlines allow a piece of around 55 x 40 x 20 to 23 cm. A soft bag gives a little, but packed full it must not exceed the permitted dimensions.
What is a wheeled travel bag?
A wheeled travel bag combines both: a soft bag body with a large opening and two wheels plus a telescopic handle. It's lighter than most suitcases of the same size yet can still be pulled along. Some models also have stowable shoulder straps.
Can I check in a travel bag as hold luggage?
Yes. Before checking in, tuck away any loose straps and shoulder straps so they don't get caught on the baggage carousel, and pack fragile items in the middle, surrounded by soft clothing. For delicate electronics, a suitcase with a solid shell is the safer choice.
