機内持ち込み手荷物とは何ですか？
機内持ち込み手荷物とは、飛行機に搭乗する際に機内に持ち込むことが許可されている物品を指す簡単な言い方です。これらの物品は、しばしば
預け入れ荷物とは異なり、機内持ち込み手荷物はフライト中ずっと手元にあります。座席の上のオーバーヘッドロッカーか、前の座席の下に収納できます。 機内持ち込み手荷物のみで旅行する 彼らは、この方法の方がキャスター付きスーツケースにこだわるよりも自由だと感じているからだ。
これらのエリアはスペースが限られているため、航空会社は通常、乗客全員の快適性と安全性を確保するために、サイズと重量の制限を設けています。
旅行者の多くは、「24インチのバッグは機内持ち込みできるのか？」と疑問に思うでしょう。答えは航空会社によって異なります。ほとんどの航空会社は、ハンドルと車輪を含めた最大長さを22インチ（約56cm）としています。しかし、サウスウエスト航空など一部の航空会社は、全体のサイズと重量制限を満たしていれば、最大24インチ（約61cm）までのバッグを受け入れる場合があります。
以下に、便利な要約があります。
Carry On Luggage Size - For UK Airlines
Let’s start with the guidelines for flights to/from the UK:
Carry On Luggage Size - For US Airlines
Traveling in the US? And wondering, “What size bag is TSA approved for carry-on?”
In general, the TSA allows carry-on luggage no more than 22 inches (about 56 cm), including handles and wheels. While the TSA does not set a weight restriction for hand bags, most American airlines do. Refer to the following information to prepare for your trip:
So, “Can I take a 22.5 inch carry-on bag Delta?” — The answer is: probably not. Delta’s carry-on size limit is 22 inches, so a 22.5-inch bag may be refused at the gate if it doesn’t fit within those dimensions.
Carry On Luggage Size - For EU Airlines
Right then, let’s see what European airlines expect when it comes to carry-on luggage and personal items.
Carry On Luggage Size - For Other Popular Airlines
And now, let's move on to the carry on luggage size guide for some major airlines in Asia:
So what should you bring as your carry-on?
Technically, you can use almost any bag as your carry-on. A wheeled suitcase, a tote, even a small duffel. But here’s the thing: it still has to fit your airline’s carry on luggage size limits. And those rules? They’re not always the same, and not always easy to figure out.
So why make things harder than they need to be? Skip the stress of measuring and second-guessing. All you really need is a CabinZero backpack.
Our bags are designed to fit the carry-on size rules of most major airlines, including 40x20x25 cm, 40x30x20 cm, 45x36x20 cm, and 55x40x20 cm. And the best part? There’s still plenty of room to pack everything you need for several days away.

Tips For Handling Carry-On at the Airport
1. Check the Dimension Before Your Flight
Most airlines allow carry-on bags up to 22 inches (56 cm) tall, 18 inches (45 cm) wide, and 10 inches (25 cm) deep. And that includes any wheels, top handles, and any side pockets.
But that doesn’t mean you can skip checking. We always recommend that you visit your airline’s website before your trip to double-check the allowed carry-on luggage size. It only takes a minute, and it can save you a lot of trouble at the airport.
Some low-cost airlines (like Ryanair or Wizz Air) are known for having stricter size rules. They do this to reduce overhead bin use and speed up boarding. In contrast, full-service airlines such as British Airways or Qatar Airways might offer a bit more flexibility, especially if you’re flying business or first class.
In case you're unsure how to measure your bag, here's how we measure ours:
- Start by placing your bag on a table or some other flat surface. Stand it upright with telescopic handles (if any) retracted.
- Measure the height from the top of the bag (the top handle usually) to the ground. Don't forget to include the wheels!
- Measure the width by taking the bag from side to side at its widest point:
- For hard-shell bags, you can place the bag on its back and measure across.
- For backpacks or soft-sided bags, it’s better to place the bag as you would normally carry it, and then measure across the widest point. Just remember to include any side pockets or straps that stick out. This will give you a more accurate idea of your carry on luggage size and how much space the bag takes up when fully packed.
- Take the depth from the rear of the bag to the front, accounting for any expanded areas or bulging due to packing.
Once you’ve got the height, width, and depth, just add them together. That will give you the total linear size. After packing, your bag still needs to fit within the airline’s limit.
The more accurately you measure your bag, the easier it is to follow airline rules.
2. Don’t Forget Weight Limit
If your hand luggage is too big, there’s a chance the airline crew might stop you at the gate. They may also ask you to put it in the hold with the checked bags. Either way, it’s best to go for hand luggage that’s light enough for you to lift and stow in the overhead compartment without a struggle.
Just like with the carry on luggage size, always double-check the weight allowance on your airline’s official website before your flight. The most common way to weigh your hand luggage is by using a home scale: either a luggage scale, a bathroom scale, or a mix of both.
A quick tip: Try to keep your bag at least 1.3 kg lighter than the airline’s maximum hand luggage allowance. That’s because home scales and airport scales might not always give the same reading. It’s better to be safe than sorry!
Now, think about what suits your journey best. It could be a small suitcase or a travel backpack with a laptop compartment. Just make sure it fits within your airline’s carry on luggage size limits. The key here is to pick one that’s as lightweight as possible when empty, like a CabinZero backpack, which can weigh as little as 600g. That will give you more freedom to pack what you really need without wasting precious weight on the bag itself.
3. Pack Smart
What’s more, here are a few simple tricks that can come in handy if you want to travel light with just a carry-on and still fit in as much as possible:
- Use packing cubes - They help keep things tidy and compress your clothes so you can fit more. We also use them to separate clean and dirty clothes, shoes, or even to store electronics safely away from moisture.
Make better use of space with packing cubes by CabinZero.
- Avoid overpacking or bringing unnecessary items - Don’t throw anything ‘just in case’ into your carry-on luggage. A well-organised carry-on is easier to carry, and it’ll give you more room to bring back souvenirs.
- Wear your heaviest or chunkiest clothes on the plane - like a thick coat, hiking boots or chunky trainers. And if you don’t mind a bit of heat or a few curious stares at the airport, layer up with a few extra shirts or trousers. There’s nothing wrong with getting around baggage fees, as long as it’s within the rules!
- Use a TSA-approved lock - On full or smaller regional flights, airlines frequently run out of overhead bin space and require passengers to gate-check their carry-on bags at the last minute. When your bag leaves your possession to go into the hold, you will want it to be securely locked.
4. Know The Differences Between Carry On vs Personal Items
The most important difference between a carry on bag and a personal item is size, specifically your airline's carry on luggage size. A carry-on is usually bigger and will fit in the overhead compartment, while a personal item is smaller and will fit under the seat in front of you.
Wrapping Up
Turns out, getting your head around carry on luggage size rules isn’t that tricky after all, right? You can save the size chart we've shared in this post, or simply take a few minutes to check your airline’s website before you start packing. And one more thing – why not choose a CabinZero bag as your travel buddy? Our designs fit even the strictest airline rules. From today on, pack more and stress less!

一般的に、ほとんどの日用品 機内持ち込み手荷物として許可されています. これらには、衣類、処方薬、ベビー用品、香水、100ml以下の容器に入った液体化粧品などが含まれます。ノートパソコンやタブレットも持ち運ぶことができます。
バッグが規定サイズを超えた場合 機内持ち込み手荷物サイズ, 航空会社はおそらく搭乗ゲートで預け入れ荷物を預けるよう求めるでしょう。そして、おそらく手数料を支払う必要があるでしょう。金額は航空会社と目的地によって異なりますが、通常は航空券購入時に預け入れ荷物を予約しておくよりも高額になります。
必ずしもそうとは限りません。世界中の主要航空会社のほとんどは、機内持ち込み手荷物のサイズを約56cm（22インチ）まで許可していますが、アジアやヨーロッパの一部の格安航空会社はより厳しく、制限サイズを53cm（21インチ）程度にしている場合があります。ですから、一番良いのは、搭乗前に利用する航空会社の規定を確認することです。
