As a Joybuy Product Recommendation Officer, I see travellers every day searching for practical solutions to comply with the baggage policies of airlines like Ryanair. The rule for the small, free personal item—a strict 40 x 20 x 25 cm—is notoriously rigid. Exceeding these dimensions can lead to unexpected fees at the gate.
This guide is designed to help you find a suitable bag that not only meets the requirements but is also functional and durable. We'll introduce a selection of models and provide useful tips for your purchasing decision.
Finding the right underseat bag for Ryanair requires more than just a glance at the price tag. Three criteria are especially important for making an informed decision.
The 40 x 20 x 25 cm dimensions are non-negotiable. Airlines often use sizing cages at the gate to check for compliance. A soft-sided 40x20x25 backpack or a flexible 40x20x25 cabin bag is often more advantageous here than a hard-shell case. Soft materials can be easily compressed if the bag isn't filled to capacity. Ensure the manufacturer's dimensions apply when the bag is empty and that it still meets the requirements when packed.
Every gram your bag weighs reduces the allowance available for your personal belongings. A lightweight carry-on backpack for the plane made from durable polyester or nylon is an excellent choice. These materials are not only light but also resistant to abrasion and often water-repellent, protecting your contents during a brief downpour.
A well-designed cabin backpack makes travelling significantly easier. Separate compartments for a laptop, travel documents, and liquids allow for quick access at the security checkpoint. A main compartment that opens fully like a suitcase simplifies packing and unpacking. Additional external pockets are practical for items you need to have readily available, like a water bottle or your smartphone.
Based on the criteria above, we have curated a few models from our collection that are suitable for different travel needs.
Why it stands out: This Kono backpack was specifically designed for the hand luggage regulations of budget airlines. With its exact dimensions of 40 x 20 x 25 cm and a 20-litre capacity, it maximises available storage space without breaking the rules. The main compartment opens fully, making packing as easy as with a small suitcase.
Advantages:
Who it's for: Ideal for budget-conscious travellers who frequently fly with Ryanair or other low-cost carriers and want to consistently avoid extra fees. Perfect for weekend trips or as an additional piece of luggage on longer journeys.
Why it stands out: This backpack is a versatile all-rounder for daily life, university, and travel. Measuring 43 x 32 x 16 cm, it's slightly larger than Ryanair's strict allowance, but its soft structure allows it to be compressed to fit the depth and width requirements when not fully packed. Its minimalist design and durable, water-repellent polyester make it a long-lasting companion.
Advantages:
Who it's for: For users who need one backpack for multiple purposes and don't exclusively travel with Ryanair. It's a great option for travellers who need a flexible daypack that can also serve as a carry-on for airlines with slightly more generous size limits.
Why it stands out: This model is not an option for the small underseat bag but rather a solution for travellers who have booked a larger carry-on or need a rugged backpack for activities at their destination. With a 40-litre volume and an advanced carrying system, it is designed for multi-day hikes and demanding tours.
Advantages:
Who it's for: For adventure travellers and hikers planning multi-day tours at their destination. It serves as the main piece of luggage for the actual adventure after the small personal item is safely stowed.
The models presented here cover a range of needs. However, if you are looking for other designs, sizes, or specific features, you are sure to find the right model in our wide selection.

1. What exactly counts as a small personal item on Ryanair? On Ryanair, the small personal item that can be brought on board for free is a bag with maximum dimensions of 40 x 20 x 25 cm. This bag must fit under the seat in front of you. Any piece of luggage that exceeds these dimensions may incur additional fees.
2. Is the size of carry-on baggage always checked by Ryanair? Checks are carried out regularly, especially on heavily booked flights. There are sizing cages at the gate that your bag must fit into. It is advisable to adhere strictly to the specifications to avoid the risk of extra charges.
3. Can a regular backpack be taken as a personal item on Ryanair? Yes, a backpack is permitted as a personal item as long as it does not exceed the specified dimensions of 40 x 20 x 25 cm. Flexible backpacks are often practical as they can be more easily fitted into the sizing cage if not overpacked.
