Suitcase Guide: How to Choose the Right Luggage for Any Trip

Are you buying a suitcase because your old one finally gave out? Or because you've graduated from "shove everything in a bag" to actually wanting your clothes to arrive uncrumpled? Either way, buying luggage is one of those purchases where the wrong call costs you — not just money, but stress at the worst possible time.

Here's what actually matters.

Hard Shell vs Soft Shell: Which Should You Choose?

Hard-shell suitcases — typically made from polycarbonate or ABS — protect your contents better, handle rough baggage systems more gracefully, and are easier to wipe clean. They're also lighter than people expect. The trade-off is a lack of flexibility: you can't squish a hard case to fit an awkward overhead locker.

Soft-shell cases are expandable, often have exterior pockets, and absorb impact differently — they flex rather than crack. They're better if you tend to overpack slightly or need to squeeze into tight spaces.

For most travellers checking a bag, hard shell wins. For cabin bags where you're wrestling with overhead lockers, soft can be more forgiving.

What Size Do You Actually Need?

Airline restrictions vary, but as a general guide:

• Cabin/carry-on: 40 litres and under. Most airlines allow 55 × 40 × 20 cm, though budget carriers are stricter.
• Medium checked: 60–75 litres. The sweet spot for a week's trip or a long weekend with clothes that need hanging.
• Large checked: 80–100+ litres. For long trips, family travel, or anyone who simply cannot travel light.

The mistake most people make is buying large when medium would do. A medium case you can actually lift is infinitely more useful than a large one you're dragging through every terminal.

Wheels: Two vs Four

Four-wheel spinners are easier to manoeuvre in airports — you can push them beside you rather than tilting and rolling. Two-wheelers (inline wheels) handle rough terrain better and are often more durable for checked luggage that gets thrown around.

For frequent flyers in smooth airport environments, four wheels are worth it. If your case spends time on cobblestones, uneven pavements, or the hold of a budget carrier, two wheels hold up better.

Locks and Security

TSA-approved combination locks are standard on most modern cases sold in the US or internationally. They allow airport security to open and relock your bag without cutting the lock. If you're travelling exclusively within the UK and Europe, any combination lock works fine — but TSA-approved is a sensible default if your bag will ever travel transatlantically.

What to Look for in the Interior

Compression straps, garment dividers, and a dedicated laptop or document section all make a difference to how organised your trip feels at the other end. Look for:

• Removable or modular organisers
• Wet pocket or shoe compartment (especially useful for beach or gym trips)
• 360° spinner wheels that feel smooth, not rattly, before you buy

Matching Your Style to Your Kit

If you're someone who owns coordinated luggage — same aesthetic across your carry-on, checked case, and personal item — you'll appreciate how an all-over print design makes your bags easy to spot on the belt and impossible to accidentally pick up by someone else. That's the whole point of luggage that actually looks like yours.

The Bottom Line

A good suitcase is quiet, smooth, has a handle that locks at the right height, and closes without a fight. Don't spend more than you need to — but don't buy cheap if you're going to use it regularly. Buy once, buy right.
