Choosing the right luggage size is one of the most important decisions before any journey.
Whether you are a frequent flyer, a business traveler, or planning a family vacation, the size of your suitcase directly affects how comfortably you travel.
At Shire Luggage, a leading luggage factory in Wenzhou, Zhejiang, China, we help global customers understand the differences between suitcase sizes — from compact 20″ carry-ons to large 28″ family suitcases — so you can travel smarter, lighter, and in style.
Understanding Luggage Sizes — 20″, 24″, 28″ and Beyond
Luggage sizes are typically measured by height (in inches).
Here’s a quick guide to the most common sizes on the market:
20″ (Cabin / Carry-On Size):
Ideal for short business trips or 2–3 days of travel.
This size is usually accepted as carry-on luggage for most airlines.
Compact, lightweight, and perfect for travelers who prefer to avoid baggage claim.
24″ (Medium Check-In Size):
Best for 4–6 day trips.
Offers enough space for clothes, shoes, and small gifts while remaining manageable in weight.
A popular choice for couples or frequent travelers.
28″ (Large Check-In Size):
Designed for long-haul or family travel.
Suitable for 7–14 days, with extra compartments for organization.
At Shire Luggage, our 28-inch PP and PC hard-shell suitcases are engineered for durability and easy maneuvering.
30″ and Above:
For long vacations or relocation.
However, this size is often too large for airline standards, and may incur extra fees.
Quick Tip: Always check airline luggage policies before traveling. Each airline has different carry-on and check-in limits.
Which Size Fits Your Travel Style?
Choosing luggage isn’t just about space — it’s about how you travel.
Business Trips (1–3 Days)
Go for a 20-inch carry-on.
Light, professional, and cabin-friendly.
Pair it with a slim laptop bag or briefcase.
Short Vacations (3–5 Days)
The 24-inch suitcase is your best friend — especially our PP series with built-in TSA locks and expandable zippers.
Family or Long-Haul Travel (7+ Days)
Choose a 28-inch or 30-inch PC suitcase.
At Shire Luggage, our PC and ABS+PC models feature reinforced corners and silent spinner wheels, making them perfect for extended travel.
Retail / B2B Buyers’ Note:
In the European market, the best-selling models are:
20″ + 24″ + 28″ sets, and
PP lightweight designs (due to eco-travel trends).
Distributors often prefer OEM suitcase sets with brand logo customization.
Luggage Material and Weight Considerations
The material of your suitcase directly affects its weight and strength.
Here’s how it connects to size choice:
ABS luggage → affordable, light, suitable for 20″ or 24″ models.
PP luggage → ultra-light and flexible, ideal for 24″–28″ cases.
PC luggage → premium and durable, perfect for larger models (28″–30″).
