Got a week away coming up and staring blankly at your wardrobe wondering how on earth it's all going to fit? You're not alone. Choosing the right suitcase size is one of those things that seems simple until you're at the airport, sweating, sitting on your suitcase trying to get it zipped shut. Let's fix that!
What Size Suitcase Is Best for a 7 Day Trip?
For most travellers, a medium suitcase (around 60 to 70 litres / 66 x 44 x 26 cm) is the sweet spot when it comes to what size luggage you need for a 1-week trip. It gives you enough room for seven days' worth of clothes without being so large that you're lugging something that feels like a small fridge through the departure hall.
The Air Glide 24" sits right in that ideal range at 66 x 44 x 26 cm. Lightweight, with 360° spinner wheels and a TSA-approved lock, so it's built for exactly this kind of trip.
What Fits in a Medium Suitcase for 7 Days?
A well-packed medium suitcase comfortably holds:
- 7 outfits
- A pair of trainers and one smarter pair of shoes
- Toiletries
- A light jacket or a thin jumper
- Chargers, a book and all the other bits you tell yourself you'll need
That said, the destination matters. If you're heading somewhere warm in summer, you might find that even a cabin bag does the job. Swimwear, shorts and linen shirts pack down beautifully.
Winter travel is a different story. One coat alone can eat up a third of your suitcase before you have packed a single outfit. Add boots, knitwear and thermals and a medium case fills up faster than you would think, even for a week away. If cold weather is on the cards, size up to a large or be ruthless about what makes the cut. A good trick: wear your bulkiest items on travel day. Your coat and boots on your body do not count towards your allowance.
What Size Suitcase for a 10 Day Trip?
For 10 days or more, a large suitcase gives you the most flexibility. The Lugg Air Glide 28" (76 x 31.5 x 51 cm, around 80s to 95 litres) is the right call if you are packing for cold weather where bulky layers take up serious room, travelling with a young child who needs extra space, or simply want to pack without compromise.
That said, a well-packed medium suitcase can stretch to 10 days if you are disciplined about what you bring. Rolling clothes and leaving the just-in-case outfits at home helps a great deal.
Medium vs Large Suitcase: Which One Do You Actually Need?
Still weighing it up? Here's a straightforward way to think about it.
A medium suitcase is the right call if your trip is 7 days in a warm or mild climate and you want to keep things simple at the airport. It's also the smarter choice if you're flying with a budget airline, where checked bag fees have a habit of quietly doubling the cost of your trip. The Air Glide 24" (66 x 44 x 26 cm, around 60 to 70 litres) is a great example - lightweight, hard-shell and built for exactly this kind of holiday.
A large suitcase like the LUGG Vacay 28" (76.5 x 30 x 50.5 cm, around 95 litres) makes more sense if you're travelling for 10 days or more, packing for cold weather where bulky layers take up serious room, or travelling with a young child and need that extra breathing space. Sometimes you just want to pack without compromise, and there is nothing wrong with that.

5 Quick Packing Tips to Get the Most Out of Any Suitcase Size
Whatever size you choose, these habits make a real difference.
- Roll, don't fold. Rolling your clothes saves more space than folding and reduces creasing. Pack smarter, not harder.
- Wear your bulkiest items on travel day. Your heaviest jumper, thickest coat and chunkiest boots do not count towards your luggage if they are already on your body.
- Switch to solid toiletries. Shampoo bars, solid conditioner and soap take up a fraction of the space of liquids and save you the bother of the security liquids bag. Plus, no spills on the way!
- Use every pocket. The front pockets and internal compartments of a good suitcase exist for a reason. Chargers, documents and small accessories can all be stored there.
- Weigh it before you leave. A portable luggage scale is one of the most useful things you can own. Some airlines charge up to £50 per extra kilo, so it pays to know before you go.
Picking the right suitcase size does not need to be complicated. For most 7-day trips, a medium suitcase gives you everything you need without the airport stress. Pack smart and you will spend less time worrying about your luggage and more time enjoying your holiday.

FAQs About Suitcase Size
What size suitcase do I need for a 7-day trip?
A medium suitcase of around 60 to 70 litres is the right size for most 7-day trips. It holds a full week's worth of clothes, shoes and toiletries without taking over. If you are heading somewhere warm and have a habit of packing light, a cabin bag might even be enough.
What size suitcase do I need for a 10-day trip?
For 10 days, a large suitcase gives you the most flexibility. That said, a well-packed medium suitcase can stretch to 10 days if you are disciplined about what you bring. Rolling clothes and leaving the "just in case" outfits at home helps a great deal.
What is the difference between a medium and large suitcase?
A medium suitcase typically holds 60 to 70 litres and works well for trips of up to 10 days. A large suitcase holds 75 litres or more and suits longer trips, winter travel or anyone who needs extra room.
Is it better to take one large suitcase or two smaller ones?
It depends on the trip. One large suitcase is simpler to manage, but two smaller suitcases split between travel companions can save on excess baggage costs. LUGG suitcase sets are a smart option here. These matching pieces store neatly together and cover every type of trip.
