Luggage Size: Length Plus Width Plus Height
Bag size limits are not about one side. Adding all three sides gives the linear total airlines actually compare.
What is the Luggage Size Checker?
Checked luggage limits often use total linear size: length plus width plus height. This checker adds your three dimensions and compares them with the common 158 cm guide. Airlines vary, and wheels and handles sometimes count, so confirm your airline's rule before flying.
How to use it
- Enter the bag length, width, and height in centimetres.
- Click Check My Bag.
- Compare the total with your airline's rule.
Worked example
A 70 by 50 by 30 cm bag totals 150 cm, within the common 158 cm guide.
Does a 70 x 50 x 30 cm bag fit the usual checked limit?
Yes: its linear total is 150 cm, under the common 158 cm guide.
Frequently asked questions
Do wheels and handles count?
Sometimes. Some airlines measure the bag including them, so include them if you want a safe answer.
What about cabin bags?
Cabin limits are stricter and separate, often around 55 x 40 x 20 cm, so check cabin rules independently.
