If you visualize the memory as rows and columns then if you need to allocate some memory in different rows[for different variables] then you have to allocate n no of cols of bytes for each variable and n is choosen as maximum size.

Variable 1 mem [8 bytes] | | | | | | | |
Variable 2 mem [4 bytes] | | | |

Instead of 4 bytes it allocates 8 to keep the packaging format in good shape for second variable memory.

If you go about by sequential memory segment then also allocating each variable memory of n [choosen as maximum] is easier and so it allocates 8 + 8 bytes instead of 8 + 4 bytes.
