A luggage set only makes sense if you’ll actually use every suitcase in it.

At LUGGEX, we offer ready-made luggage sets for common travel styles, but we also know that no two travelers pack the same way. A frequent business traveler may need a carry-on and one large checked bag. A family may want three sizes. Someone who flies mostly within Europe may want a smaller carry-on altogether.

So instead of starting with “Which set looks best?”, start with a simpler question:

What kinds of trips do you actually take?

Here’s how to build the right combination.

Start With the Size You’ll Use Most

19″ Carry-On — Best for European Air Travel

Best for: Europe trips, light packers, frequent short-haul flyers
Typical trip: 2–4 days
Capacity: 31L

The LUGGEX ZX 19″ is our most compact carry-on and is designed around common European cabin-size limits. Its dimensions meet the published size limits of roughly 80% of the European airlines included in our comparison. 

Choose the 19″ if airline compatibility matters more to you than squeezing in one more outfit.

Pairs well with: 24″ or 28″ check-in luggage.

Airline policies vary by carrier, route, fare, and aircraft. Always confirm the current allowance before flying.

20″ Carry-On — The Everyday All-Rounder

Best for: weekend trips, frequent flyers, travelers who use different U.S. airlines
Typical trip: 2–4 days
Capacity: 36L

The 20″ is the safest starting point for most LUGGEX sets. It gives you useful carry-on capacity without moving too far into oversized territory and is the closest of our core ZX carry-ons to common U.S. airline dimensions. 

If you only want one carry-on to cover the widest range of everyday trips, start here.

Pairs especially well with: 24″, 26″, or 28″.

21″ Carry-On — More Room for Longer Carry-On Trips

Best for: business travelers, long weekends, people who hate checking bags
Typical trip: 3–5 days

The 21″ category gives you more flexibility. The ZX Bigger Carry-On offers more packing room, while the ZX Pro All-in-One adds front laptop access for travelers moving between airports, hotels, and meetings. 

Choose 21″ if extra space or faster laptop access matters more than maximum airline compatibility.

Pairs well with: 28″ or 30″.

22″ Carry-On — Maximum Carry-On Space

Best for: longer carry-on-only trips, generous airline allowances, heavy packers
Capacity: 50L

The ZX 22″ is about capacity first. It offers the most packing space among the core ZX carry-ons, but it also has the least flexibility across airlines. LUGGEX currently positions it around carriers with larger allowances such as Southwest, Frontier, and Sun Country. LUGGEX

Choose this one because you know your airline allows the size, not because “22 inches” sounds close enough.

Pairs well with: 28″ for travelers who want maximum space at both ends.

Now Choose Your Check-In

24″ — The Easy-to-Handle Check-In

Best for: solo travelers, business trips, one-week vacations
Typical trip: 3–7 days
Capacity: about 72–75L

The 24″ is the middle-ground option for someone who wants checked-bag capacity without hauling around a huge suitcase. 

It makes particular sense if you travel often and would rather pack a little smarter than move a 100-liter suitcase every time.

Best match: 20″ + 24″.

26″ — The Most Versatile Check-In

Best for: one-week trips, frequent travelers, couples who pack efficiently
Typical trip: 5–9 days
Capacity: 82L

Think of the 26″ as the bridge between medium and large checked luggage. It gives you noticeably more room than the 24″ without jumping all the way to the size and weight of a 28″. 

If you’re unsure whether you need a medium or large check-in, 26″ is usually the easiest compromise.

Best match: 20″ + 26″.

28″ — The Long-Trip Favorite

Best for: long vacations, international travel, winter clothing, overpackers
Typical trip: 7–14 days
Capacity: 103L

This is where you go when packing space really starts to matter.

The ZX 28″ gives you enough room for longer wardrobes, bulkier layers, shoes, and extended trips. LUGGEX also designed the 20″ carry-on to nest inside the 28″ for easier storage at home. 

For many travelers who want just two suitcases to cover most trips, the combination is simple:

20″ + 28″.

30″ Trunk — For Seriously Big Trips

Best for: two-week-plus trips, family packing, moving, study abroad, bulky gear
Typical trip: 14+ days
Capacity: 115L

The 30″ isn’t an everyday suitcase. That’s exactly the point.

Its deeper trunk-style compartment works better for bulky items and high-volume packing than a typical medium checked bag. 

Choose it if your normal packing list includes things like coats, multiple pairs of shoes, equipment, or extended-stay essentials.

Best match: 21″ + 30″.

32″ — Maximum Capacity

Best for: extended stays, relocation, family road trips, maximum-capacity packing
Capacity: 130L

The 32″ is the largest option in the current ZX lineup. It makes sense when capacity comes first and airline oversize rules are already part of your planning. 

For ordinary week-long vacations, it’s probably more suitcase than you need.

Prefer an Easy Answer? Start With One of These Sets

If you don’t want to build from scratch, LUGGEX already offers combinations based around common travel patterns. 

The 20″ + 28″ combination is the simplest place to start if you want only two pieces: one for short trips and one for longer travel.

The 20″ + 24″ + 28″ set makes more sense if several people in your household travel or you want more flexibility without buying another suitcase later. LUGGEX currently positions this three-piece combination as its Family Set. 

Don’t See Your Combination? Build Your Own.

This is the part I think should become one of the strongest conversion points in the article.

You do not have to choose one of our preset luggage sets.

On the LUGGEX Luggage Set & Bundle page, you can mix and match eligible carry-ons, check-in luggage, trunks, and accessories to create a combination that makes more sense for the way you travel.

For example:

European traveler:
19″ + 24″

Frequent U.S. traveler:
20″ + 26″

Business + vacation:
All-in-One 21″ + 28″

Long-term traveler:
21″ + 30″

Family that already owns carry-ons:
24″ + 28″

Heavy packer:
22″ + 30″

And because the bundle builder works across different eligible pieces, you don’t have to buy two suitcases of the same series or accept a size you don’t actually need. The current page also includes automatic bundle savings:

Spend $299 → Save $20
Spend $399 → Save $30
Spend $499 → Save $50

Add the pieces you want to your bundle, add them to cart, and the qualifying savings are applied automatically. Current promotions can change, so check the live bundle page for the latest offer. 

Build Your Own LUGGEX Luggage Set

One Last Rule: Buy for Your Real Trips

A three-piece set isn’t automatically better than a two-piece set.

A 32″ suitcase isn’t automatically better than a 24″ because it holds more.

And the biggest carry-on isn’t necessarily the best carry-on if your airline won’t accept it.

Start with the trips you take most often. Choose the smallest pieces that comfortably handle those trips. Then add capacity only when you know you’ll use it.

That’s how you end up with a luggage set that spends more time traveling—and less time sitting in a closet.

All LUGGEX luggage purchased through LUGGEX.com is also supported by the brand’s Lifetime Limited Warranty, and the site currently offers 30-day free returns, giving you another layer of support when choosing your setup.
