Luggage Measuring - Size Of Baggage
The TSA (Travel Security Admission) website states the size dimensions or carry-on luggage and checked luggage allowed in the cabin vary by airline. Contact your airline or visit their website for more information on specific sizing restrictions prior to flying.
Carry-on luggage, the majority of US. airlines have limitations of about what size limit they allow for a carry-on. For example, most cap the size at 22 in. (22 in. x 14” x 9”) and cannot big bigger than 45 linear inches. This is the length + width + height and includes handles and wheels, meaning 22+14+9 = 45 linear inches. That’s 115 cm = 23 x 36 x 56 cm.
Checked luggage, which means the bigger size luggage 24 in. and over, the majority of US. airlines have limitations on this as well.
