You can use the .sizeof property on the type.

```
import core.simd;
void main() {
     ubyte16 a;
     ushort8 b;
     pragma(msg, a.sizeof);
     pragma(msg, b.sizeof);
     pragma(msg, a[0].sizeof);
     pragma(msg, b[0].sizeof);
     pragma(msg, typeof(a[0]));
     pragma(msg, typeof(b[0]));
}
```
