.. LenB return the in-Memory Size of a User Defined Type when you have a dynamic array inside it?
from MSDN:
LenB Function Returns in-Memory Size of User-Defined Type
And it says nothing about dynamic arrays in it. I tested resizing a Integer array inside the UDT and it returned 4 whatever size it was.

Perhaps VB stores the dynamic array as a pointer, so it doesn't take the other memory?

A dynamic array is stored as a pointer to the data in it. Pointers are 4 bytes.

Do some arithmetic.
Looks to me as though you need to use Ubound & Lbound functions. Then do some arithmetic. Consult documentation on how much storage required for each item in array.
By the way, it often pays to use fixed length strings in arrays, avoiding the 10-Byte overhead per string for variable length strings.
