How tall/big is Anivia?

Apologies, if this is posted in the wrong section of the boards, but I could not find a more fitting place.

As the title suggests, I would like to know if there is any information on how tall anivia is.

The question arose in me, when I read a thread ( fanfiction I believe, I found it by searching for "anivia"), that states that: "Anivia is resting on Ashs shoulder"

To me this seemed realy odd, since I always pictured anivia about the size of a small plane, with talons big enough to shred a human in pieces and a beak big enough to easily chop a persons head off.

I asked in the anivia discord whether they knew about her size. I looked into the "LoL Universe" Page about her and read old and new Lore, but I could not find any Information about it. So far the conclusion is, that we just do not know. We had depictions discussed of a decently sized Eagles up to half the size of Aurelion sol....

If riot would have an answer, that would be highly apreciated. Thank you for reading.
