To choose the right luggage size, match your bag dimensions and weight to standard airline categories while accounting for your trip length and whether you are flying domestic or international.

---

### 1. Personal Items (Under-Seat)

- Standard Size: Roughly 17 × 10 × 9 inches to 18 × 14 × 8 inches (H × W × D) - Weight Limit: Rarely weighed on domestic flights, though some international carriers enforce strict caps (e.g., 15-17 lbs / 7-8 kg). - Best For: Laptops, purses, small backpacks, or briefcases that fit completely under the seat in front of you. - Tip: Basic economy tickets on some major U.S. carriers (like United) restrict you to only a personal item, with no overhead carry-on allowed.

### 2. Carry-On / Cabin Bags (Overhead Bin)

- Standard Size: Most U.S. and regional carriers use 22 × 14 × 9 inches (including wheels and handles). International or budget carriers can be smaller (e.g., 55 × 40 × 23 cm). - Weight Limit: Domestically, weight limits are usually ignored as long as you can lift the bag into the overhead bin unaided. Internationally, many airlines enforce strict caps (often 15 to 22 lbs / 7 to 10 kg). - Best For: Trips lasting 1 to 5 days if you want to skip baggage claim waits and checked bag fees.

### 3. Checked Luggage (Hold / Cargo)

- Standard Size Limit: Most airlines cap checked bags at 62 linear inches (total height + width + depth combined). - Example: A 28-inch suitcase measuring 28" + 20" + 12" equals 60 linear inches. - Standard Weight Limit: Typically 50 lbs (23 kg) for Economy on domestic and most international routes. Budget airlines often lower this to 40 lbs (18 kg) or charge per kilogram. - Breakdown by Trip Duration: - Small Checked (23-24 inches): Ideal for 3 to 5 days. - Medium Checked (25-27 inches): Ideal for 5 to 10 days. - Large Checked (28-32 inches): Ideal for 10 to 14+ days or bulky winter gear.

---

### Key Rules to Avoid Extra Fees

- Check Linear Dimensions, Not Just Height: Manufacturers measure the box, but airlines measure the entire exterior including wheels, feet, and top handles from floor to tip. - Weigh Your Bag Before You Leave: A 50-pound limit is strictly enforced at check-in; overweight or oversized fees can range drastically from $30 up to several hundred dollars. - Verify International vs. Domestic Rules: A bag that flies free as a carry-on on a domestic U.S. leg might trigger a weight check or size rejection on a regional international connection. Always consult your specific airline's baggage policy page before packing.

If you'd like, let me know:

- Are you flying domestic or international? - Which airline are you using? - How many days is your trip?

I can check the exact baggage limits for your trip.

When buying a suitcase, prioritize durability, weight, wheels, size, and warranty over appearance or brand name. A good suitcase should be easy to maneuver, withstand rough handling, and last for years.

Here are the 10 things I'd pay attention to before purchasing.

## 1\. Material: Hard shell vs. soft shell

!LUGGEX 28 Inch Expandable Checked Luggage Opening Polycarbonate Hardside Suitcase with TSA Approved Lock FLO FX Core Black FX-FLO5CE-BK28XP - Best Buy

Hard-shell suitcase

- Better protection for belongings - Easier to clean - More resistant to tearing - Can scratch or crack

![Lightest Large Suitcase in Navy - Soft Stripe 2.0 | Soft Checked Suitcase - Antler UK](

Soft-shell suitcase

- Often lighter - More flexible storage - Usually has exterior pockets - Can tear or absorb moisture

Best materials to consider\:

| Material | What to know | |--------|--------| | Polycarbonate | Excellent balance of flexibility, strength and weight | | Polypropylene | Lightweight and flexible | | ABS plastic | Less expensive, generally less durable | | Aluminum | Premium protection, but heavier | | Ballistic nylon | Durable soft-sided option |

My recommendation: Polycarbonate is a great starting point if you want a hard-shell suitcase.

## 2\. Wheels: One of the most important features !Samsonite 73h Suitcase 71cm expandable!Travelite Meet 2-wheel business trolley 43 cm - navy!Avalon Softside Large Check-In | Ricardo Beverly Hills![Crew Classic Compact Carry-On / Medium Check-In Set in Patriot Blue - Travelpro]( Pro-dlx 4 Spinner 55/20 Exp!2 Piece Check In & Carry On Luggage Set | Versapack+ by Travelpro!Samsonite B-lite 4 Spinner 55/20 Exp

Look for\:

- Four 360-degree spinner wheels. - Smooth, quiet rolling. - Wheels that feel firmly attached. - Double wheels if you prefer added stability. - Replaceable wheels are a bonus.

Two wheels vs. four wheels\:

- Four wheels: Easier to maneuver through airports and hotels. - Two wheels: Better for sidewalks, uneven pavement and cobblestones.

My recommendation: Four-wheel spinners for airport travel; two-wheel rollers for rougher terrain.

## 3\. Zippers and locks !Traveler's Choice Archer Polycarbonate Hardside Spinner Luggage Set, Tie Down Straps, Black, Checked 29-Inch(Blue) - Travelers Choice![Large Suitcase - Personalise Your Luggage]( バーマス スーツケース 92L ヘリテージ3 ファスナータイプ 60542 Lサイズ キャリーケース 大容量 頑丈 静音キャスター ストッパー付き TSロック ダイヤル式 トラベルセントリーID 5泊 国内 海外 旅行 出張 ビジネス 大きめ HERITAGE ブラック シルバー グリーン：Gretsch![Optima® Expandable Carry-on Spinner - Travelpro]( Paris Helium Aero 29" 4-Wheel Large Luggage - Luggage Online!user!グランプラス ケーツー スーツケース Sサイズ 40L/47L 機内持ち込み 拡張機能付き Grand+ K2 ground-k2 キャリーケース ｜ONLINE STORE by SELECTION

Check for\:

- Quality zippers, preferably YKK. - Zippers that open and close smoothly. - Reinforced zipper stitching. - TSA-accepted combination lock. - Zippers that don't snag when the suitcase is full.

Don't underestimate zipper quality. A broken zipper can make an otherwise good suitcase unusable.

www.consumerreports.orgwww.consumerreports.org

## 4\. Weight

A heavy suitcase eats into your airline baggage allowance before you've packed anything.

Here are some useful targets\:

| Suitcase type | Suggested empty weight | |--------|--------| | Carry-on | 5-7.5 lbs | | Medium checked | 7-9 lbs | | Large checked | 8-11 lbs |

These are practical shopping targets, not airline regulations.

www.consumerreports.orgwww.consumerreports.orgwww.consumerreports.orgwww.consumerreports.org

## 5\. Handle quality ![【フロントオープン＆収納力抜群の8cm拡張】STAND U plus - MAIMO公式オンラインショップ](

Look for\:

- Adjustable handle heights. - Comfortable grip. - Minimal wobbling. - Smooth extension and retraction. - Sturdy construction.

A flimsy telescoping handle is a warning sign.

## 6\. Interior organization !Ensemble de bagages rigides 3 pièces: Valises grandes 28 pouces et 24 pouces avec roulettes, et Valise Cabine 20 pouces - Walmart.ca!US Traveler Citrine Hardside Spinner Luggage with TSA Lock & USB Charging System!Carry On Classic | Nomatic Australia!Delsey Shadow 5.0 3-Piece Smart Luggage Set with Carry-On, Medium and Large Suitcases | Wayfair![Optima® Expandable Carry-On / Medium Check-In Set - Travelpro]( Elegance Carry On Suitcase, 20â€_x009d_ Hardside Luggage with TSA Lock, Spinner Wheels-Black, 20-Inch!Travel Pop - Custom Medium Check-In Suitcase | Lime & Lou!H7 Pro - Smart Check-In Case | Horizn Studios!SWISSGEAR Cascade II Hardside Carry On Spinner Suitcase - Black: - Total Liquidators!KSK2493 - Kono Durable ABS+PC 20 inch Carry-On Hardshell Suitcase with TSA Lock & Front Laptop Compartment - Navy

Look for\:

- Compression straps. - Zippered divider panels. - Mesh pockets. - Separate compartments. - Laundry or shoe storage. - Expandable capacity if needed.

A well-designed interior can make a big difference when packing.

## 7\. Size and capacity

Choose the size based on how long you typically travel.

| Size | Typical use | |--------|--------| | 18-21 inches | Weekend trips / carry-on | | 24-26 inches | Trips around 1 week | | 27-30 inches | Longer vacations / checked luggage |

Important: Always check the airline's carry-on dimensions. Include wheels, handles and exterior pockets when measuring.

www.consumerreports.orgwww.consumerreports.org

## 8\. Expandability !Large Expandable Suitcases: Coast Blue | Away

An expandable suitcase gives you extra packing room.

However\:

- It can exceed carry-on size limits when expanded. - The expansion zipper is another potential weak point. - More capacity can encourage overpacking.

## 9\. Warranty and repairability

This is something many buyers overlook.

Look for\:

- At least a few years of warranty coverage. - Coverage for wheels, handles and zippers. - Available replacement parts. - Accessible repair services. - A reasonable return policy.

Read the exclusions carefully. A lifetime warranty doesn't necessarily cover airline damage or cosmetic scratches.

## 10\. Brand and overall construction

Some established brands worth comparing include\:

## My pre-purchase checklist
