Aren’t both wrong? By definition %i is a signed integer, and size_t is unsigned.
So %zu or %llu would be more correct:

They all seem to do the job though:

Correcting myself. Here is why you cannot use %zi:

   $ cat alfa.c
   #define __USE_MINGW_ANSI_STDIO 1
   #include <stdio.h>
   int main() {
     printf("%zi %zu %llu\n", __SIZE_MAX__, __SIZE_MAX__, __SIZE_MAX__);
   }

   $ x86_64-w64-mingw32-gcc -o alfa alfa.c

   $ ./alfa
   -1 18446744073709551615 18446744073709551615
