My only main issue is that I have trouble internalising how big a 4000 miles giantess would even be, so it's difficult to accurately picture the story in my mind any help? reference material ect.

Author's Response:

I always like to start with idea that the smallest size something can be seen at by the naked eye at a close range is 0.5 mm- the diameter of a speck of dust. The equivalent of a 4000 mile tall woman would be something 1 mile- so I set it up that she can see an extremely tall skyscraper (in the real world none are that tall, but they get very close)- which is what I set up in the most recent chapter. 

I wanted the microputian population to be >100,000,000 so it's a large nation, contained within an ant-farm that's maybe 1 foot by 1 foot on prodi scale . That would mean it's about 500,000 square miles (size of New England and New York state) on micro scale, or 200 of them/square mile, which is typical of the US east seaboard.

Her fingertip would be about 20 miles by 30 miles. 

Looking forward to seeing more of this story!  Stories with microputians/nanoputians and prodigans are the best. I hope to see lots of tiny POV!

Love it so far!
