I looked at the meta data and became interested in how height was determined and that interest developed into this mod.
Overall it is a height scaling mod that changes the height range for each race/clan/gender to average at 1.00 in the meta data, and gives a height range around that average that makes sense to me.
This change gives most categories a wider range of possible heights, brings most of the "human" based races together in height range, and decreases the gender dimorphism in the Au Ra.
Lots and lots of option boxes because I wanted to give flexibility if you like the changes in one group, but not another. Hover over the information bubbles to get an idea for each option how much it changes things.
A touch more detail on how I came up with my numbers:
This mod adjusts the heights of all races so that 50% on the character creation slider is equal to the 1.00 height in the meta data.
Take the Miqo males: Original average height is around 65.5 inches and translates to .95 in the meta data, making 1.00 the average bring their average height up to about 68.9 inches
Then I was a little geeky and looked at real world humans. I took the average height of humans and two standard deviations (which covers about 95% of the population). With those numbers I figured out what percentage a standard deviation was of the average height. I applied those percentages back into the final fantasy races and got a new range of max and min heights!
Real world human males: average height of 69 inches, each standard deviation is about 3 inches. So 95% of human males will fall between 75 to 63 inches. Got my numbers from a quick google search, so please correct me if i am wrong.
So, with the numbers I have that means that each standard deviation is about 4.35% of the average height, so two standard deviations is 8.7%
Going back to the male Miqo example: The old height had a range from 68.2 to 62.7 inches, a range of 5.5 inches. Applying two standard deviations to the 1.00 average height gives us a range of 74.9 to 62.9 inches, a range of 12 inches.
Funny enough by averaging around 1 many character options start to fall in the range of real world humans. Hyur, Au Ra, Viera, and Miqo'te males almost exactly match real world human averages. The female FF races have more variety by an inch or two and only Hyur and Viera get really close to matching real world data.
I have some ideas for other height mods in the future, so this might not even end up being the one I use, but I had fun being a nerd and wanted to share this!
Enjoy!
