Travel Luggage Size Guide: How to Choose the Right Suitcase for Every Trip
Choosing the right suitcase shouldn’t feel like solving a puzzle.
Whether you’re staring at a wall of luggage in-store or endlessly scrolling online, the options can get overwhelming. 24-inch or 28-inch? Will your carry-on pass the airline’s “strict” rules? And the real question — will it fit everything you want to bring?
Let’s take the stress out of packing. This guide breaks down luggage sizes in a way that actually makes sense, tailored to your trip length, packing style, and airline policies. From quick weekend escapes to extended getaways, consider this your no-stress suitcase sizing cheat sheet.
THE 3 MAIN LUGGAGE SIZES (AND WHAT THEY’RE GOOD FOR)
You’ve probably heard the terms “carry-on,” “medium,” and “large” luggage. But what do they actually mean? Here’s a quick breakdown:
| Type | Typical Size | Perfect For |
|---|---|---|
| Carry On | Up to 22" tall | Short trips, 2–5 days |
| Medium Checked Bag | Around 24–26" | 5–7 day trips |
| Large Checked Bag | 27–30" | Week-long or longer trips |
Keep in mind that actual dimensions vary slightly between brands. Always check your airline’s baggage policy before you fly, as it may vary from one airline to another.
Pro Tip:
If you’re shopping for a new suitcase, bring a measuring tape or check dimensions online before buying. Size labels like “medium” or “large” aren’t standardized, so a 26″ bag from one brand might be a 28″ bag in another.
WHAT SIZE SUITCASE SHOULD YOU CHOOSE BASED ON YOUR TRIP?
Let’s get real. How long you’re going for and how much you tend to pack – matter more than the fancy label on the tag. Here’s what works for most travelers:
For a 5-Day Trip
A medium-sized suitcase (24–26″) is usually a safe bet. It’ll hold a week’s worth of outfits, shoes, and toiletries without being oversized. If you’re a light packer, you might even get away with a carry-on, especially if laundry is an option.
Packing tip:
Use packing cubes to save space and keep things organized. You’d be surprised how much more fits in when your clothes are neatly compressed.
For 7 to 10 Days
Go with a large suitcase (27–30″). You’ll need the extra space for layers, shoes, and maybe some souvenirs on your way back. Just be mindful of weight limits. Anything over 50 lbs can get you slapped with extra fees.
Bonus:
Use a luggage scale before you leave for the airport. It’s cheaper to rearrange at home than pay excess fees at the counter.
Weekend Getaways or Overnight Trips
No need to overdo it. A carry-on suitcase (20–22″) or even a decent-sized travel backpack should cover everything. Less hassle, no baggage claim, and you’re out of the airport in minutes.
Tip:
If you’re flying budget airlines, double-check their carry-on restrictions. Some only allow personal items unless you pay extra.

WHAT COUNTS AS TSA-APPROVED OR AIRLINE-APPROVED LUGGAGE?
Airlines have rules, and ignoring them can cost you. Here’s a quick cheat sheet:
- Carry-On Bags: Most airlines allow bags up to 22” x 14” x 9” (wheels and handles included).
- Personal Item: Think laptop bag, small backpack, or tote that fits under the seat in front of you.
- Checked Bags: Should be under 62 linear inches (length + width + height) and weigh less than 50 lbs (about 23 kg).
Wondering about 28-inch suitcases? They’re totally fine to check, as long as they meet the size and weight requirements. Don’t overstuff them, and you’re good to go.
Common Misconception:
Just because your suitcase fits in the overhead bin at home doesn’t mean it will pass the airline gate test. Airlines can be strict, especially with full flights.
THINGS TO THINK ABOUT BEFORE BUYING YOUR LUGGAGE
Besides size, there are a few more details that can make your travel life easier:
1. Where Are You Going?
Packing for Iceland in winter? Bulky coats mean more space. Beach trip to Thailand? Light and breezy stuff won’t take much room.
Also, consider the weather. Humid destinations may need different clothes than dry ones, and that affects how much space you’ll need.
2. How Much Do You Pack?
Some of us can live out of a backpack for a week. Others need three outfit changes a day. Be honest about your packing style.
If you’re the “just-in-case” packer, consider investing in expandable luggage or one size up.

3. Will You Be Carrying It On or Checking It?
If you want to skip baggage claim, keep it small. But if you need more room, checked luggage is your friend – just don’t forget about airline weight limits.
Checking bags also adds potential delays or lost luggage risk, so weigh the pros and cons based on your travel style.
4. Hard-Shell vs Soft-Shell?
Hard-shell suitcases are sturdier and protect fragile stuff. Soft shells give you a little wiggle room when you want to squeeze in that extra sweater.
If you’re traveling by car, bus, or train, soft shells are easier to compress into tight spaces.
Most MOST COMMON QUESTIONS ABOUT LUGGAGE SIZES
Let’s clear up some of the most Googled questions people have about luggage sizing:
1. What’s the Biggest Bag I Can Check on a Plane?
Generally, you can check a bag up to 62 linear inches. Go beyond that, and most airlines will charge you for an oversized bag.
If you frequently travel with sports equipment or musical instruments, consider bags made specifically for oversized items to avoid damage or fees.
2. What Size Is “Travel Size” Luggage?
Usually, that refers to carry-on luggage – anything around 20–22 inches high.
Also, “travel size” can refer to toiletries. For carry-ons, make sure liquids are in containers 3.4 oz (100 ml) or smaller, all packed in a quart-sized clear bag.
3. Is a 28-Inch Suitcase Too Big?
Not at all. Most 28-inch bags fit within the allowed limits for checked luggage. Just make sure you’re not over the weight limit.
If you tend to overpack, look for lightweight luggage to offset your gear weight and stay under the 50 lb mark.
4. What Are the Three Standard Suitcase Sizes?
- Carry-On: 20–22 inches
- Medium Checked: 24–26 inches
- Large Checked: 27–30 inches
Having one of each lets you mix and match based on trip type, airline, or how much shopping you plan to do!
IS IT WORTH BUYING A LUGGAGE SET?
If you travel often or share bags with family, a luggage set can be a smart investment. Most sets come with a carry-on, a medium suitcase, and a large one, giving you options for every kind of trip. Bonus: They usually nest inside each other for easy storage.
Look for sets with:
- Spinner wheels (life-changing, honestly)
- Expandable zippers
- Strong zippers and handles
- Lightweight but durable shells
A well-designed luggage set saves money long-term. If you travel as a couple or family, it also means coordinated sizes and shared storage without playing Tetris every trip.
QUICK CHECKLIST: ASK YOURSELF BEFORE BUYING A SUITCASE
- How long are my typical trips?
- Do I usually fly budget airlines with strict limits?
- Do I overpack?
- Will I use packing cubes or just roll clothes?
- Do I need to store this easily at home? Nesting sets help!
Answering these will narrow your options and make sure you’re not buying something you’ll regret later.

WRAPPING IT UP
Choosing the right luggage size doesn’t need to be complicated. Think about your destination, how long you’ll be away, and how much you like to bring along. Whether it’s a short weekend break or a two-week adventure, there’s a suitcase that fits just right.
Key takeaway? If you’re going away for 3–5 days, go for a carry-on or medium bag. For longer trips, a large checked suitcase (just under 62 linear inches) gives you the freedom to pack smart, without stress.
Skip the guesswork. Pick the size that fits your travel life and enjoy the ride.
