Size of a structure

Technically, the size of a structure is the amount of bytes that need the variables of the structure.

For example, if I use the next standard structure:

; building the sockaddr_in struct
push 0  ; INADDR_ANY
push WORD 0x672b ; port 11111
push WORD 2 ; AF_INET

2 tutorials I'm reading say: sizeof(struct sockaddr) = 16 (socklen_t)

But I only see 1 dword and 2 words = 8 bytes. 8 bytes, no 16. What am I doing bad? The tutorials don't use macros, they put the imm value and no more.

DB  ?
