Okay. I had to look this up several times because I was kind of surprised.

A320 Fleet
Main doors (1LR and Rear LR): 1829x829 mm or 72 x 32

A321
Emergency Exit Doors
2L: Size: 1854 x 762 mm (73.0 x 30.0 in.)
2R, 3LR: Size: 1524 x 762 mm (60.0 x 30.0 in.)

The 2L forward emergency exit door is usable as a normal passenger/crew door



That would be nice, eh?

757
Book I show says 1L and 2L are 72 x 33.
Doesn’t seem to show it in mm. Odd.
