Can I bring a backpack as a personal item?

Yes, most airlines allow a backpack as a personal item as long as it fits within their dimension limits. The key is whether it fits under the seat in front of you. Use our calculator to check your specific backpack against any airline.

What happens if my bag doesn’t fit the gate sizer?

If your bag doesn’t fit the gate sizer, you’ll typically be asked to check it at the gate. Airlines like Ryanair charge €50–70 for gate-checked bags, while US carriers are usually free. Knowing before you fly saves money and stress.

Do airlines measure wheels and handles?

Yes, most airlines include wheels, handles, and external pockets in their measurements. Our dimensions reflect the full external size of each bag including these features.

How accurate is the Fit Score?

Our Fit Score is calculated using official airline dimension data from each carrier. We track and update these dimensions regularly. The Squish Score adds a material-based compression estimate, which reflects real-world conditions at ~80% packing capacity.

Q: What is the Squish Score?

The Squish Score is our proprietary 1–5 rating that measures how much a bag can compress based on its material. A rigid hard-shell scores 1 (no compression), while ultralight nylon scores 5 (up to 4 cm of compression). This helps determine if a slightly oversized soft bag can still squeeze into a gate sizer.

Enter your bag dimensions, pick your material type, and instantly see which airlines your carry-on fits. Our Squish Score factors in how much a soft bag can compress into tight gate sizers.

How to Measure

Length — tallest dimension, from floor to top of handle/wheels

Width — widest side, including external pockets

Depth — front to back, at the thickest point

Always measure the full external size — wheels, handles, and pockets count. Manufacturer specs often exclude these.

What is the Squish Score?

Not all bags are rigid boxes. A soft bag that is slightly over the limit can still squeeze into a gate sizer if the material compresses. We rate bags from 1–5:

1 Rigid (Hard-shell suitcases)0 in

2 Semi-Rigid (Soft shell + frame)0.2 in

3 Structured Soft (Padded backpacks)0.8 in

4 Flexible Soft (Frameless backpacks)1.2 in

5 Max Squish (Packable daypacks)1.6 in
