GameplayTag byte size?

What’s the size of a gameplay tag? It’s a name, so 8 bytes (two int32)?

I’m taking name as 8 bytes from FName docs (but could be wrong)
“stored as a combination of an index into a table of unique strings and an instance number.”

Thanks

It’s 12 bytes according to this insanely useful gist that lists all the sizes (insert meme) ^^,
