There aren't any documented structures unless they are used in scripts (in which you need to then search the code).

Really your only option is to calculate the size itself.

Data types : Size

• Byte : 1
  
• Integer : 2
  
• Long : 4
  
• String : 4
  
• Variant : 8

If you have Visual Basic 6 installed you can cheat and declare a variable as a specific structure then do MsgBox Len and it will tell you the size of the structure.
