The first word of the var data is the size. It's the same as the word you
use for the corresponding create var call. There's a call (_get_var_size
equ 477Fh) that gets the size of any variable. This should work...

ld hl,name
call _FINDSYM
ex de,hl
call _get_var_size
...

_get_var_size takes the type in a (returned by _FINDSYM) and the pointer to
the var data in bhl (_FINDSYM returns it in bde). It returns the size of
the variable (in bytes) in de, and the var data ptr in ahl.
