Hey there, If you're staring at a beautiful trolley bag in a store or online and wondering, “Which size should I go for?”, you’re at the right place. Picking the right luggage for your trip can feel like a puzzle, but once you know the basics, you’ll find your perfect travel luggage in no time.

Why luggage size matters

Starting with the right size ensures that you:

• Avoid extra baggage fees
  
  

• Have enough space for what you need
  
  

• Keep things compact and light when desired

Common luggage sizes you can go for are:

1. Cabin trolley bag — perfect for carry-on

Think short weekend escapes, light travels, or wish to skip baggage claim? Cabin luggage is your friend.

Pros:

• Fits most airline carry-on rules
  
  

• Saves time at the airport
  
  

• Harder to overpack, so you stay organized
  
  

Considerations:

• Packing space is tight and great for minimalist packing
  
  

• Might still be slightly over baggage-size for ultra-strict carriers (so double-check your airline)
  
  

WanderX’s Denver carry-on (aluminum) is extra compact yet sturdy, perfect for short trips.

2. Medium trolley bag 

Medium size is the all-rounder. Think a week-long trip, mixed weather, or family packing.

Why you’ll love it:

• Ample space without losing manageability
  
  

• Offers more compartments for good organization
  
  

• Still carries like a trolley bag, not a suitcase
  
  

WanderX Berlin (soft luggage) is one of the best medium sized trolley bag in the market

3. Large luggage — for long trips or group travel

Heading on long holidays or packing for kids? Time to go large.

Things to note:

• This luggage gives you tons of room, but packing thoughtfully is key
  
  

• It’ll still work with trolley wheels, but lifting is less fun
  
  

• May attract overweight baggage fees depending on airlines
  
  

Berlin large and Osaka large are both roomy and great options.

Hard vs Soft Luggage: Does Material Affect Luggage Size Choice?

• Hard luggage (e.g. polycarbonate, aluminum) offers great protection and maintains its shape. 

• Soft luggage (like soft-sided canvas or polyester) can give a little room if needed, and often weighs less. 

If your trip involves delicate items, hard is smart. If you need flexibility for souvenirs or laundry, soft gives that stretch.

Conclusion

Choosing luggage isn’t just about size, it’s about how you travel. A small cabin trolley bag is perfect for fast, light trips. A medium bag covers most needs comfortably. And when big adventures or family packing is in question, a large bag has your back. Choose the size that is perfect for you and your trips and you will have no regrets.
