What the estimate uses

CarrySizer stores fee records separately from size rules, so the calculator can show when a bag technically fits but still needs a paid cabin-bag add-on, or when checking a bag online is cheaper than resolving it at the gate.

Frequently asked questions

How much is a gate fee for an oversize carry-on bag?

Gate fees for a cabin bag that's too big are typically €45–€70 (about $50–$100), and most airlines charge roughly double what the same bag costs to add online beforehand. Ryanair, Wizz Air, and easyJet are among the strictest enforcers.

Is it cheaper to pay for a bag online or at the airport?

Almost always online. Pre-paying for extra or oversize baggage when you book — or in the airline's app before you reach the airport — usually costs 40–60% less than paying at bag drop or the boarding gate.

What's the difference between an overweight and an oversize fee?

An overweight fee applies when a bag is over the weight limit (a flat charge or a per-kilo rate). An oversize fee applies when the bag's dimensions exceed the size limit, regardless of weight. One bag can trigger both at once.

Do low-cost airlines charge for carry-on bags?

Many do. Ultra-low-cost carriers like Ryanair, Wizz Air, and Frontier include only a small under-seat personal item in the base fare; a larger cabin bag for the overhead bin needs a paid add-on or a higher fare.
