Carry-On Suitcases: A Smart Traveller’s Buying Guide

Planning a short trip, for business or leisure? Preparations often start with the same question: which carry-on suitcase should I take? It needs to meet the airline's size requirements, roll smoothly through the terminal, and keep your belongings safe. The selection is vast, and it's easy to get lost in all the options.

This guide is designed to help you. We'll discuss the most important factors to consider and provide a few concrete recommendations for 2026, based on product specifications that truly matter. This will help you make an informed choice that suits your travel style.

What to Look for When Buying a Carry-On Suitcase?

Before you choose a model, it's helpful to know which features make all the difference. Here are three practical tips.

1. Dimensions and Weight: Meeting the Requirements

The most common size for a carry-on suitcase is around 55 x 35 x 25 cm, but this varies by airline. Therefore, always check the current regulations of the airline you're flying with. A lightweight suitcase is a plus, as it leaves you more weight allowance for your luggage. Most hardside suitcases weigh between 2.5 and 4 kg when empty.

2. Material: The Advantages of a Hardside Suitcase

A hardside suitcase generally offers better protection for your belongings than a softside version. Most hardside suitcases are made of polycarbonate (PC) or ABS.

• Polycarbonate (PC): This material is very strong, flexible, and lightweight. It handles impacts well and flexes under pressure, which reduces the risk of cracking.
• ABS: This is a slightly cheaper and more rigid material. It is scratch-resistant but less flexible than PC.

A suitcase with a textured surface is less prone to visible scratches, which helps it look new for longer.

3. Ease of Use: Wheels and Locks

The comfort of a trolley largely depends on its wheels. A 4-wheel suitcase, also known as a spinner, can rotate 360 degrees and be rolled upright beside you. This is less strenuous on your arm and shoulder than a 2-wheel suitcase, which you have to pull behind you.

For security, a suitcase with a TSA lock is a wise choice, especially if you are travelling to the United States. The Transportation Security Administration (TSA) can then open your suitcase with a master key for inspection without breaking the lock.

Frequently Asked Questions About Carry-On Suitcases

What are the standard dimensions for carry-on luggage?

There is no universal standard, but most European airlines use a guideline of approximately 55 cm (height) x 35 cm (width) x 25 cm (depth). Budget airlines often have stricter and smaller limits. Always check this on the airline's website before departure.

Is a hardside or softside suitcase better for carry-on?

A hardside suitcase offers superior protection against impacts and is more water-resistant. This is ideal for transporting fragile items. A softside suitcase is more flexible and often has exterior pockets but offers less protection. For carry-on luggage, which you control yourself, both are good options, but a hardside shell often provides more peace of mind.

What is a TSA lock and do I need one?

A TSA lock is a lock that can be opened by the US Transportation Security Administration (TSA) with a master key. If you are travelling to or through the US, this is highly recommended. If the TSA wants to inspect your suitcase and you do not have a TSA lock, they are permitted to break your lock. It also provides a secure way to lock your suitcase for travel outside the US.
