How do I check if Vim is compiled as 64-bit or 32-bit from within vimscript? Specifically on Windows.

1 Answer 1


Testing the value of the win64 feature should tell you:

:echo has("win64")

If the output is 1, then your Vim installation is 64-bit.


:help has()
:help feature-list

and search for 64.

    To anyone that wonders how to use has, in command mode, you should type :echo has("win64")
