Check a bag against common airline size and weight limits: enter its dimensions and weight, adjust the limits if an airline differs.
Airlines measure cabin bags by individual dimensions and many checked bags by linear size — length plus width plus height added together. The preset limits are common examples and are fully editable, because limits differ by airline, route and fare class. Always confirm against the specific booking before travelling; a bag that passes a common limit can still fail a stricter fare rule.
What is linear size? Linear size is length plus width plus height added together. Many checked-bag limits are expressed this way, for example 62 linear inches (157 cm), rather than as three separate maximums.
Should wheels and handles be included? Most airlines measure the bag as presented, including wheels and extended handles where they add to the size. Measure the full outside of the packed bag.
Why are the limits editable? Because there is no single standard. Low-cost, economy and premium fares on the same airline can have different cabin and checked limits, so the exact figures from a booking can be entered directly.
