Every object has an object header. That’s 8 bytes on a 32-bit machine, 4 for the sync block and 4 for the type handle. A value type value only derives from System.Object when it is boxed. An int is 4 bytes when it unboxed, 12 bytes when it is boxed, +8 bytes for the header.
Check this answer to get more insight in what a boxed value type looks like.
