On Wizz Air, the free allowance is an underseat bag; the overhead trolley requires WIZZ Priority. Find sizes, common mistakes and a checklist here.
How many kilograms and what size is Wizz Air cabin baggage? The free allowance is a bag that fits under the seat, measuring at most 40 x 30 x 20 cm and weighing 10 kg. For the 55 x 40 x 23 cm trolley of 10 kg placed in the overhead bin, WIZZ Priority is required. Below you'll find the differences, common mistakes and a checklist.
In brief
- The free allowance is only a 40 x 30 x 20 cm and 10 kg underseat bag.
- WIZZ Priority is required for the 55 x 40 x 23 cm trolley; verify the allowance separately for each passenger.
- Measure the bag including wheels, handles and pockets; weigh it when full and make sure it does not exceed 10 kg.
- Check your airline's current rule for additional fees and up-to-date conditions before buying your ticket.
The core of the rule: two separate cabin baggage allowances
On Wizz Air, cabin baggage isn't a single rule; there are two separate allowances, one free and one not.
- Free small bag (underseat): at most 40 x 30 x 20 cm and 10 kg. This allowance applies to all passengers.
- Large cabin baggage (trolley): at most 55 x 40 x 23 cm and 10 kg. It goes in the overhead bin and requires WIZZ Priority.
The weight limit is the same for both: 10 kg. What changes is the size. With the cheapest ticket, you only have the underseat bag allowance. So if your ticket doesn't include Priority, don't plan to bring a wheeled cabin suitcase into the cabin; your bag needs to fit the underseat dimensions.
This distinction is the most commonly misunderstood point at the airport. Before buying a ticket, check which allowance you've purchased from your booking summary. Check the detail of the rule and possible updates from your airline's current rule.
Dimensions and weight: the logic of two boxes
Instead of memorizing the numbers, think of two boxes.
Underseat bag
The upper limit is 40 x 30 x 20 cm and 10 kg. When measuring, don't just look at the body of the bag; also account for wheels, handles and outer pockets. A backpack with full outer pockets may fit the measurement when empty but can bulge and exceed the limit when full.
Overhead bin trolley
The upper limit is 55 x 40 x 23 cm and again 10 kg. All three dimensions need to stay within the limit; a full suitcase whose length fits but whose thickness is excessive can cause problems. The manufacturer's label measurement often doesn't include wheels and handles, so measure it yourself with your own tape measure.
Practical tip: Measure and weigh your suitcase at home. For bags close to the limit, soft-bodied models fit the template more easily; hard-bodied suitcases leave no margin. Don't forget to weigh it when full, because the 10 kg limit applies including the contents of the bag.
Ticket type and the WIZZ Priority difference
Your cabin baggage allowance depends on what's included in your ticket. The cheapest Wizz Air ticket only includes an underseat bag allowance of up to 40 x 30 x 20 cm and 10 kg. Passengers who purchase WIZZ Priority can also bring cabin baggage of up to 55 x 40 x 23 cm and 10 kg.
When buying your ticket, check the following:
- Does Priority appear in your booking summary?
- Did you select Priority separately for each passenger? Verify the allowance separately for people traveling together.
- Is the allowance available on both outbound and return flights?
The conditions and timing for adding Priority afterward may vary; check your airline's current rule. Since the Priority price varies by route and date, we don't provide a figure on this page. To see ticket options side by side and compare flight conditions, you can enter your route on the search for flight tickets page. Evaluating the baggage allowance together with the ticket price is the easiest way to understand the real cost of a ticket that looks cheap.
Exceptions and common mistakes
The situations that cause problems at the airport are generally the same.
- Bringing a trolley without purchasing Priority: This is the most common mistake. The free allowance is only the small bag; a large suitcase can be converted into hold baggage at the gate and may incur an additional fee.
- Counting all your items under a single allowance or assuming extra items are allowed: Don't assume you can also bring your coat, laptop bag or shopping bag separately. Check your airline's current rule on this matter.
- Reading the dimensions from the label: The manufacturer's label often doesn't account for wheels and handles.
- A backpack with full pockets: A bag that fits when empty may not fit the sizing template when full.
- Forgetting the liquids and gels rule: Even if your cabin baggage's size is correct, items may be confiscated at security due to liquids. Security limits are applied according to the airport; check the departure airport's current rule.
Most of these mistakes are prevented by a two-minute measurement and weighing at home before departure.
Step by step: how to prepare your baggage
If you follow the order below, you're less likely to face surprises at the gate.
- Check your ticket. Does your booking include WIZZ Priority, or do you only have the small bag allowance?
- Choose the right bag. If you don't have Priority, prepare a bag that fits 40 x 30 x 20 cm; if you do, prepare a trolley that doesn't exceed 55 x 40 x 23 cm.
- Measure it. Measure length, width and depth with a tape measure, including wheels, handles and pockets.
- Weigh it. Weigh the full bag on a scale or with a hand scale; it should not exceed 10 kg.
- Distribute heavy items. Remember that heavy items such as books, power banks and chargers are included in the total weight.
- Sort out what doesn't fit beforehand. If the limit is exceeded, remove items at home rather than giving them up at the airport.
Baggage needs vary according to trip length; a short weekend getaway and a two-week trip can't be solved with the same plan. On longer trips, adding hold baggage is generally more comfortable than pushing the cabin limit. Check the current hold baggage rule from your airline's page.
Checklist before heading out
Tick off the following items before heading to the airport.
- I have confirmed whether WIZZ Priority is included in my booking.
- My underseat bag does not exceed 40 x 30 x 20 cm.
- If I have a trolley, it does not exceed 55 x 40 x 23 cm and my Priority allowance is registered under my passenger name.
- My bag is under 10 kg; I checked it with a scale.
- I included wheels, handles and outer pockets in the measurement.
- I separated liquids, power banks and chargers according to security rules.
- I have my ID or passport, boarding pass and booking summary with me.

Frequently asked questions
How many kilograms can Wizz Air's free cabin baggage be?
The free underseat bag can be at most 10 kg for all passengers. The size limit is 40 x 30 x 20 cm. Check the airline's current rule for bags that exceed this limit.
Can a trolley suitcase be taken into the cabin on Wizz Air?
Yes, but WIZZ Priority is required. With Priority, a trolley that doesn't exceed 55 x 40 x 23 cm and doesn't exceed 10 kg can be taken into the cabin. Without Priority, you only have the underseat bag allowance.
What are Wizz Air's cabin baggage dimensions?
40 x 30 x 20 cm for the underseat bag, and 55 x 40 x 23 cm for the trolley placed in the overhead bin. The weight limit is 10 kg for both. Measure including wheels and handles.
What happens if I bring a large suitcase without WIZZ Priority?
Since the suitcase exceeds your cabin allowance, it may be converted into hold baggage at the gate and an additional fee may apply. Since the fee varies by route and time, check the current amount on the airline's page. The safest way is to confirm your allowance before buying your ticket.
Can a backpack and a suitcase be taken into the cabin together?
Passengers with WIZZ Priority can also bring their underseat bag in addition to the trolley. A passenger without Priority only has the small bag allowance. If you're carrying two items, check the detail from your airline's current rule.
Who checks the cabin baggage size at the airport?
Checks are generally carried out at the gate by airline staff using a sizing template and scale. For this reason, it's recommended that you measure and weigh your bag yourself before departure. For bags close to the limit, flexible-bodied models are safer.
