Carry-On vs. Checked: Suitcase Size Guide
Summary
Not sure which suitcase size is right for your trip? This guide breaks it down with simple tips—like using liters to estimate nights, understanding carry-on vs. checked baggage, and planning space for shopping. Pack smarter and travel with ease!
Picking the right suitcase size doesn’t have to be confusing.
Whether you're planning a quick weekend trip or a long vacation, choosing the right size can make your journey much smoother.
This easy-to-follow suitcase size guide offers three simple tips to help you find the perfect fit for your travels.
1. Suitcase Size Guide: Think in Liters — 10L = 1 Travel Night
As a general rule, every 10 liters of suitcase capacity covers about one night of travel.
So if you're going on a 3-night trip, a 30L bag should be enough.
But keep in mind: if you’re heading somewhere cold, your clothes will be bulkier—so you might need a bit more space.
■ Quick Size Reference
● Carry-On Size / XS – Total dimensions within 100 cm – For 1–2 days
● Carry-On Size / S – Total dimensions between 101–115 cm – For 2–3 days
● Check-In Size / M – Up to 59L – For 3–5 days
● Check-In Size / L – 60–79L – For 5–7 days
● Check-In Size / XL – 80–99L – For 7–10 days
● Check-In Size / XXL – 100L and up – For 10+ days
Note: This is a general guideline. Actual needs may vary depending on how much you pack.
*Unit Reference: 1 cm = 0.3937 inches, 1 L = 0.2642 US gallons / 0.2199 UK gallons
2. Carry-On or Check-In? Know the Rules
When flying, knowing whether your suitcase qualifies as carry-on or needs to be checked is essential.
■ Carry-on
Great for short trips. You can skip baggage claim, avoid extra fees, and keep everything with you.
Just make sure your bag (including wheels and handles!) meets airline size limits.
Perks: Faster, cheaper, and less risk of lost luggage.
■ Checked luggage
Better for longer trips or when you need more space.
Perks: More room, easier packing—but expect to wait at baggage claim.
Choose what fits your trip style—and always check the airline’s rules before you fly!

If you're planning to shop a lot during your trip, leave extra room in your suitcase.
Use packing cubes or compression bags to save space and keep things organized.
