BAG CHECKER
Is my bag OK?
Choose your airline, then enter measurements or use the photo guide.
Two photos. One size estimate.
Place an A4 sheet or a metric ruler flat against the same face as your bag. With a ruler, use the 0–10 cm marks.

AIRLINE RULES
Popular airlines, one simple format.
Rules can change. Every entry shows its source and last check date.
HONEST BY DESIGN
A photo gives an estimate—not a promise.
A normal photo has no real-world scale. That is why our guide asks for an A4 sheet or metric ruler in the same plane as the bag, plus a second side photo for depth.

Before you rely on the result.
Does a green result guarantee boarding?
No. It means your measurements fit the published limit. Airport staff and the airline have the final say.
Are wheels and handles included?
Rules vary. We measure the full outer size to be safe. Wizz Air has a specific exception for handles and wheels; check its source link.
What happens to my photos?
They are read only inside your browser for the current check. This first version does not upload or store them.
