And anyone noticed that the guys didn't seem so tall when they appeared in pictures with other people: Sir George (in the studio) or Peter Brown (in John's wedding) just two examples I remember now. There are videoclips of John... for example: at the beginning of Stand By Me clip John and Yoko entered the white limusine and the man besides them are taller than John (how big the limusine was!!)... if John, Paul and George were 5 11 the other men were 6 03 at least!!! I think John was about 5 08 and Paul and George about 5 09.

The Guys with Sir George (1963)
I think Ringo was about 5'6.5'' (169 cm), John about 5'8.5'' (174 cm), George about 5'9.25'' (176 cm) and Paul, clearly the tallest, about 5'10'' (178 cm).
