A medium suitcase is the sensible default for a week away. It holds enough for most people without becoming too heavy to lift, and it usually fits within the checked baggage limits of most airlines. This is a buying guide, not a review. We have not tested the products or brands mentioned in general terms, so use this to understand what to look for, then check current specifications, prices and customer reviews before you buy.
What size for a week?
For a week-long holiday, a medium suitcase is the usual choice. Sizes are not standardised across brands, so one maker’s medium can be a little larger or smaller than another’s. Look at the actual dimensions and capacity on the product page, not just the word medium.
Your own travel style matters more than the label. If you pack light and re-wear clothes, you may manage with a cabin bag. If you travel with bulky items such as coats, beach gear or children’s belongings, you may prefer a larger case or two smaller ones. Think about the climate, the length of the trip and whether you will do laundry.
Quick sizing questions
- How many outfits do you need for the week?
- Do you need winter layers, or mostly light summer clothes?
- Will you bring home souvenirs or shopping?
- Are you travelling alone, as a couple or as a family sharing cases?
How many litres?
Capacity is often shown in litres, and medium suitcases commonly sit somewhere in the middle of the range between cabin-sized and large cases. Rather than memorising a number, compare capacity against the cases you already know. Many product pages list a capacity in litres and external dimensions, and some also give an expandable capacity. Check whether the quoted size includes the wheels and handles, because external measurements matter for airline limits.
Capacity versus weight
A bigger case is not always better. A large case filled to the brim can easily exceed an airline’s weight allowance and become awkward to carry. A medium case encourages you to pack only what you need. Check your airline’s checked baggage allowance, because both size and weight limits apply and rules vary by fare. Our guides to easyJet, Jet2, Ryanair and British Airways cabin baggage cover the carry-on side of the same question.
Features that add useful space
- Expandable zips, which add capacity but also add weight risk, so use them carefully.
- Compression straps inside the case, which help keep contents tidy.
- Dividers and zipped pockets for shoes and toiletries.
Hard or soft?
Hard-shell and soft-sided cases each have strengths, and the right choice depends on how you travel.
Hard-shell cases
Hard cases offer better protection for fragile items and often look smart and modern. They resist rain and give a firm structure, which helps stacking. They do not flex, so overfilling can be a problem, and scratches and scuffs tend to show. A polycarbonate or similar flexible hard shell may absorb knocks better than a rigid one.
Soft-sided cases
Soft cases usually have external pockets, which are handy for quick-access items, and they have a little give if you need to squeeze in one more item. They can be lighter. They offer less protection for fragile items and can be more vulnerable to rain and snagging, depending on the fabric.
How to decide
- If you carry delicate items, lean towards hard.
- If you like quick-access pockets and flexible space, lean towards soft.
- If weight is a priority, compare the empty weight of specific models.
- If you often travel by coach, train or car, either type works well.
Which brands last?
We have not tested suitcases, so we cannot rank brands on durability. What we can do is show you how to judge it. Long-lasting luggage tends to have sturdy wheels, strong handles and zips, solid stitching and a warranty you can rely on. A longer guarantee is a useful signal, as long as you read what it covers, because many warranties exclude damage caused by airlines.
Read recent customer reviews across several retailers and look for patterns over time, such as wheels failing or handles snapping, rather than one-off complaints. Be sceptical of reviews that read as promotional, and check the number of reviews as well as the average score. Consider whether spare parts and repairs are available.
What to check before buying
- Wheel type: four spinner wheels roll easily, while two larger wheels can cope better with rough surfaces.
- Handle: a smooth telescopic handle that locks at several heights is easier to use.
- Zips: look for chunky, well-attached zips, ideally with a lock option.
- Lock: a built-in combination lock is convenient. Check whether it is compatible with common security inspections.
- Warranty: read the length and what it covers.
- Return policy: buy from somewhere that makes returns easy, so you can test the case at home.
Spinner wheels or two wheels?
Four spinner wheels let you glide a case alongside you and are easy in airports and on smooth surfaces. They can roll away on slopes and are more exposed on cobbles, kerbs and rough ground. Two-wheeled cases are tilted and pulled, handle uneven surfaces more steadily and often have more protected wheels. If your holidays involve cobbled streets or stairs, think about which will suit you.
How much should you spend?
Prices vary widely, and we are not going to quote figures, because they change frequently. A sensible approach is to set a budget, then compare features at that price. A mid-priced case with a good warranty can be better value than a very cheap one that needs replacing, but a high price does not guarantee quality. Watch for seasonal sales, and compare prices across retailers before buying.
How to test a suitcase when it arrives
Whether you buy online or in a shop, give the case a proper check before the first trip. Open and close every zip several times and make sure they run smoothly. Extend and lower the handle and look for wobble. Roll the case across a few surfaces, then lift it by the top and side handles. Fill it with a typical week’s clothes and see how it feels, because a case that is comfortable when empty can feel very different when full. If anything seems wrong, return it within the retailer’s window rather than hoping it will be fine.
It is also worth checking the interior. Look for a lining that feels sturdy, stitching that is even and straps that are firmly fixed. Check the case against your airline’s size limits using a tape measure, including the wheels and handles, so you know it fits before you reach the airport. Keep your receipt and warranty details somewhere safe.
Looking after your case
- Wipe it clean after each trip and let it dry fully before storing it.
- Store it with the handle down and zips closed, somewhere dry.
- Avoid overpacking, which stresses zips and wheels.
- Add a luggage tag with your details, and a distinctive strap to spot it quickly.
Packing tips for a week
Choose a colour palette so items mix and match, roll or fold clothes consistently, and use packing cubes to keep the case organised. Put heavier items near the wheels, and keep liquids in a sealed bag. Leave a little space for the journey home. Weigh the case at home on a luggage scale before you leave, to avoid surprise fees at the airport.
A simple week checklist
- Documents, tickets and insurance details in a bag you keep with you.
- Medication and valuables in your hand luggage, not the hold.
- Chargers and adaptors packed together.
- Toiletries within allowed limits for cabin bags, if you carry them on.

Medium suitcase FAQs
Is a medium suitcase allowed as hand luggage?
Usually not. Medium cases are typically meant for the hold, and cabin bag limits are smaller. Check your airline’s rules.
What is the best colour?
A distinctive colour makes your case easier to spot on the carousel, while darker colours hide marks. Pick what suits you.
Do I need a lock?
A lock can deter opportunistic theft and keep zips closed. Choose one that is compatible with security inspections.
How long should a suitcase last?
With reasonable care, a well-made case can last many years, but the real answer depends on the model and how you travel.
Should I buy a set?
Sets can be good value if you need several sizes, but only buy a set if you will use every piece.
Can I repair a suitcase?
Some brands and local repair shops can replace wheels, handles and zips. Check the warranty and repair options before buying.
Final thoughts
Measure up against your airline’s limits, pick a style that suits how you travel, and read recent reviews before you commit. For more help planning, see our guides to easyJet baggage and cheap package holidays abroad.
