Calculating the height without a full body shot

[Comiphorous]

Right now im attempting to calculate the height of a big ass metal blue rabbit, with a shot of him standing directly in front of a 6'1 woman.

problem is, i don't have a shot of either person's body. (the shot is roughly at the woman's chest, and the waist of the rabbit) how would i go on calculating the height without their full body? there isn't any other shots of them near eachother besides this one, but i do have a fullbody render of my metal rabbit friend.

Can you link the images?

edit: didn't mean to put the ones with my pixel scaling, but i guess it works.

edit2: fixed. no more pixel scaling version.

Nvm fixed it.

Do you have a full body image of the women?

There are no full-body images of her that i know of.

how's this?

metal bunny's height = 185.42*607/503 = 223.76 cm or 7'4

bump? sounds like theres a better way to do it.

If you know for sure the girl is 6'1 its pretty simple.
6'1 = 185.42 cm
Plug that into your Human Proportions Calculator using Woman and An Adult Body Type.
This gives you a head height of 23.2 cm and a chin to shoulder line of 7.8 cm for a total of 31 cm. Now you pixel scale your line using that as your ruler.
Divide the 31 cm by the amount of pixels the line was to get the number of cm in a pixel. Then pixel scale the head of the Rabbit, and get the measurement of the head in cm.

The Human Head takes up 13% of the total body height.
The measurement of the head = 13% of total body height.

Although it's a Rabbit Head, It should still be fine to use the Human Head, at least in my opinion.

Spoiler: Example

To give you an example, let's say the measurement of the head was 65 cm. Let H be the total height.
65 / H - 13 / 100

65 x 100 - 13 x H

6500 = 13H

H = 6500 / 13
H = 500 cm

To confirm your answer, just google 13% of 500 or the total height.

Considering how disproportionate the animatronics are, Bon's head is proably a chunk bigger than a human's, but it probably won't change the end results by that much.

Which formula is this? I see it for the first time.

There's no formula? It's just basic pixel scaling and Algebra.

I didn't see it in calculation guides before, how did you find the height with this method.

There are multiple ways to do a calculation, this is just one of them. Everything I did to find the height is listed.

Generally the human body is seven and a half human heads tall using artistic proportions, so in a situation where such is viable (as in not too cartoony), use that.

the full body render for the bunny animatronic is available to use tho

Yes you can also just pixel scale the head of the woman using the Human Proportions Calculator, then pixel scale the rabbit, then using the same pixel scale, apply it to the full body image.

kind of hard to pixel scale the head of the woman, since she's facing away from the camera, and her hair isn't making it any easier to see where her head roughly is. (unless im misinterpreting your comment)

In the image, you can get a good estimate of where her neck ends, which is why you measure the head height and the chin to shoulder line as shown in the human proportions calculator.
