max_align_t is a type whose alignment requirement is at least as strict (as large) as that of every scalar type.
[edit] Notes
Pointers returned by allocation functions such as malloc are suitably aligned for any object, which means they are aligned at least as strict as max_align_t.
max_align_t is usually synonymous with the largest scalar type, which is long double on most platforms, and its alignment requirement is either 8 or 16.
