Re: Human Proportion to Scale ?

If you want to apply a scale to something, you need to know its actual size first.

For example, let's say a human has a height of 1.8m (180cm). In this case, a 1/6 scale model would have a height of 180 * 1/6 = 30cm. If the human's arms are 60cm, then the model's arms would be 10cm, etc. You always need a measurement to apply the scale to.

Why did the vector cross the road?
It wanted to be normal.

I suppose I have to found out a average humans height Then I multiple that by 1/6 which will give me the actual scale height.

Hi Superlynx;

Mathsy has explained it correctly to you. And you and I covered this right here.

Re: Human Proportion to Scale ?

Bobbym I was going to mention this in my original thread that we talked about this You mentioned though that you should know the scale of the model in that thread but I don't know what the actual proportions of a human is to multiple it by.  Mathyperson mentioned 180 CM now if this is correct then 30 CM is right, but that is what I'd like to know what is the average height ?

5'10 for a male human ? That is the first question
Then how do you convert feet and inches to CM to figure out the scale  ?

Hi SuperLynx;

Then how do you convert feet and inches to CM to figure out the scale  ?

5' 10 '' = 70 inches = 177.8 cm

The average height worldwide for the human male is 5' 7" tall.

Re: Human Proportion to Scale ?

Mathyperson was right.  Something 1/6 in scale as he mentioned would be close to if not 30 CM. 
Thank you Bobbym and Mathyperson Now I have my answer
