Airbus 319 etc

Hi - anyone able to provide a concise view on the differences between A319/320/321 ?
thanks

Length.

321 is a 320 stretch.
319 is a shortened 320.

The emergency exit door configurations are also different.


319 One overwing exit*
320 Two side-by-side overwing exits
321 Emergency exit forward and aft of the wing

*Some 319s configured for high density seating have the 320 emergency exit configuration (eg Easyjet)
