Enter your inputs

Normal size data

Here you may enter any known data about your girl: in this side of the page, you must think of her as being normal-sized. The more you fill, the better!

Only integer values greater than zero are allowed, except for the hips to waist ratio field below that allows decimal values between 0.55 and 0.85.

Girl's data
Normal-size height (cm)
Normal-size weight (kg)
Hair length (cm)
Eyelash length (mm)
Fingernail length (mm)
Hips to waist ratio
Bust size

Giantess size data

Now it's time for giantesses to become part of the equation! Using the following forms, you can tell us her height as a giantess. Inputs are cumulative, the system will add all things in all boxes together.

How tall is your giantess?
Meters
Kilometers
Light-years
Observable universe diameters

If you don't know her precise height, don't worry: you can just tell us how much bigger than her normal-sized height she is (e.g. 50 times) using the following form! Of course, do not fill both forms at the same time or else you might get an error: just use the most appropriate one given the data you have on your own character!

Scaling factor
Scaling factor (pure number)

This calculator has a lot of functionality, but not every user will want to know every thing. It can become quite long with all things showing—which is great if you want to know exactly how wide a single strand of her hair is, but that's not needed for most people. Please select what information outputs you would like to see.

FAQs

Are any of these forms optional?

The forms in the 'Normal size data' section are optional; if any of them are left blank, we'll automatically fill them up with pre-set values. The forms in the 'Giantess size data' are compulsory (but the user can decide whether to input the girl's height as a giantess or the scaling factor).
