Luggage Size Guide: What You Need for Carry-On, Checked, and Beyond

January 27 2025, by Carolina UC, 6 min reading time

Traveling can be stressful enough without the added worry of luggage restrictions. With airlines setting strict size and weight limits, it’s essential to know the different types of luggage and how to pack within the guidelines. Whether you're flying for business or leisure, understanding what you need for carry-on, checked, and oversized luggage can save you time, money, and a whole lot of hassle at the airport. Let’s break it down.

Carry-On Luggage: What Fits in the Overhead Bin?

Carry-on luggage is the bag you bring with you into the cabin, which needs to meet specific size restrictions. Most airlines set a standard limit for carry-on bags, but it can vary slightly depending on the airline. The general dimensions for carry-on luggage are typically around 55 x 40 x 20 cm, which should fit in the overhead bin. Some airlines may allow slightly larger or smaller sizes, so it’s always worth double-checking before you pack.

When it comes to weight, airlines usually impose a limit, typically between 7kg and 10kg. This is to ensure that the bag doesn’t exceed the overhead bin’s weight capacity. If you're unsure, check your airline’s website to avoid the dreaded baggage fees at the gate.

To make the most of your carry-on, consider opting for a lightweight bag. Look for materials like polycarbonate or fabric with sturdy zippers, which keep the bag durable without adding unnecessary weight. Also, many modern carry-ons come with expanders, offering a little extra room when needed.

Checked Luggage: Bigger, But Not Too Big

Checked luggage is what you’ll leave at the airline counter before heading through security. Unlike carry-ons, checked luggage offers more space, but it also comes with its own size restrictions. The general size limit for checked luggage is typically 158 cm when you add the length, width, and height together.

For example, a standard large suitcase is often around 75 cm high, 50 cm wide, and 30 cm deep. While this size is commonly accepted, always check with your airline for their specific baggage policies.

Weight limits for checked luggage are often higher than those for carry-ons, typically around 23kg for most airlines. However, keep in mind that overweight luggage can incur hefty charges. If you’re travelling internationally, you may be able to check in two pieces of luggage without paying extra, but this can depend on your ticket class or frequent flyer status.

Oversized Luggage: When Bigger is Better… or More Expensive

Sometimes, you just need more space, whether it's because of a big sporting trip or a family vacation. Oversized luggage refers to any bag that exceeds the standard size limits for checked baggage. Generally, this means a bag that’s longer than 158 cm in total dimensions.

While oversized luggage might be necessary for specific types of trips (think skis, golf clubs, or surfboards), it can come with a premium price tag. Airlines often charge additional fees for oversized luggage, and the larger your bag, the more you’ll likely pay. Be sure to check your airline’s oversized baggage fees in advance to avoid any surprises at the airport.

If you frequently travel with oversized luggage, it’s worth investing in special bags or cases designed to minimise fees and ensure safe transport. Keep in mind that some airlines offer a sports equipment allowance, which might be cheaper than paying for oversized luggage.

Personal Item Size Rules: The Bag You Carry Everywhere

In addition to your carry-on luggage bag, most airlines allow you to bring a personal item. This could be a backpack, laptop bag, or small handbag, and it’s meant to fit under the seat in front of you. While the size rules for personal items aren’t as strict as those for carry-ons, they generally have to fit within 40 x 30 x 15 cm or a similar dimension.

Make sure that your personal item is small enough to fit under the seat but still spacious enough to carry your essentials, such as a wallet, phone, charger, and a book or tablet. While it may be tempting to stuff everything into your personal item, remember that you'll still need to be able to access it easily during the flight.

Luggage for Short vs. Long Trips: Pack Smart, Pack Light

The type of luggage you choose depends greatly on the length of your trip. For short trips, a carry-on bag might be all you need. With the growing trend of “carry-on only” travel, packing light is more popular than ever. If you’re heading away for just a few days, consider using a compact, expandable carry-on to fit everything without checking in a bag.

For longer trips, checked luggage becomes more necessary. Whether you’re going on a long holiday or business trip, it’s best to have the extra space for clothing, toiletries, and other essentials. However, even on long trips, try to pack strategically. Instead of cramming your suitcase to the brim, focus on versatile clothing that can be worn in multiple ways. Using packing cubes can also help maximise space.

Smart Luggage Features: The Future of Travel

As technology advances, so does luggage. Smart luggage has become a popular choice for the savvy traveller, offering features like built-in charging ports, GPS tracking, and digital locks. Some brands even offer self-weighing luggage to ensure you’re not caught off guard by baggage fees at the airport.

While smart luggage can be incredibly convenient, there are some considerations to keep in mind. Some airlines have restrictions on lithium-ion batteries, which are commonly found in smart luggage. If you’re considering buying a smart suitcase, double-check the airline's regulations to make sure it meets their requirements.

Adhering to Size Limits for Airport Ease

The most important piece of advice when it comes to luggage is to always adhere to your airline’s size and weight limits. Not only will this save you from unnecessary fees, but it will also make your journey through the airport smoother. Being aware of these restrictions means you won’t have to worry about the dreaded “excess baggage” charges when you check in.

To make things easier, pack early and weigh your luggage at home before heading to the airport. This will give you peace of mind, knowing that you’ve met all the guidelines. If your luggage is over the limit, consider repacking or opting for a different bag that meets the requirements.

Final Thoughts

Choosing the right luggage size for your trip is more than just a matter of convenience; it’s about planning ahead to avoid unnecessary stress and fees. Whether you're opting for a compact carry-on, checking in a large suitcase, or handling oversized luggage, understanding the various size restrictions and packing smart will make your travel experience far more enjoyable.

So next time you’re getting ready to jet off, make sure you’re clear on your luggage’s size and weight limits. After all, the journey begins with a well-packed bag!
