Exact comparisons
Dimensions use all six orientations, and internal values are never rounded down.
Pre-release · Offline-first
Know how your bag compares before you reach the airport.
BagGauge compares dimensions and weight you enter with published airline baggage limits, then explains exactly where a bag fits or exceeds them.
A published-limit comparison is not a guarantee of acceptance at the airport, check-in desk, or gate. Your ticket conditions and airline staff determine what applies.
Built for clear decisions
Published limits, explained without guesswork.
Missing or ticket-dependent information stays visible instead of being replaced by a convenient industry average.
Official provenance
Every verified rule includes its airline-owned source and verification date.
Private by default
Bag profiles, trips, and check history stay in local Chrome extension storage.
