About CarrySizer

CarrySizer helps travelers compare their bag dimensions and weight against airline carry-on rules. The site covers cabin bag limits, personal item rules, route checks, fee estimates, and side-by-side airline comparisons.

The goal is simple: give travelers a clear first answer before they pack, book an add-on, or arrive at the gate.

Carry-on rules change by airline, fare, cabin class, route, and booking timing. CarrySizer keeps the information structured so a traveler can quickly understand the practical limit that matters for a trip.

The tools are designed for quick checks, not legal guarantees. Travelers should still confirm critical baggage details directly with their airline before flying.

Airline entries are researched from public airline policy pages, fare rules, and baggage information. Records include source references and review dates so older data can be revisited.

When the data is incomplete or outdated, CarrySizer shows a cautious result and points users back to the airline for verification.

CarrySizer is independent and is not affiliated with, authorized by, or endorsed by any airline.

Airline names, fare names, logos, and trademarks belong to their respective owners and are used only to identify published baggage policies.
