Giantess Calculator

Welcome to Fifteen1413 & LabbaArt's Giantess Calculator! If you have ever wondered how small the world would appear to eyes of your OC, or, conversely, how big she'd really be if you were to meet her, then here is where you can find a precise numerical answer to such questions and more.

Step 1

Normal-size data

Here you may enter any known data about your girl (you must think of her as being normal-sized for the time being). 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.

Normal-size height (cm)
Normal-size weight (kg)
Hair length (cm)
Eyelash length (mm)
Fingernail length (mm)
Hips to waist ratio
Bust size
Step 2

Giantess-size data

This is where size becomes part of the equation! Using the following forms, you can enter your character's true height. Inputs are cumulative, so the numbers in each field will automatically be added together at the end.

If you don't know her precise height, you can simply type how much bigger she is compared to her normal-sized self (e.g. 50 times) using the scaling factor field. Of course, do not fill both types of field at the same time or you will get an error: just use the most appropriate one given the data you have on your own character!

Are any of these forms optional?

The forms in the ‘Normal size data’ section are optional; if any of them are left blank, it will automatically be filled with pre-set values. The forms in the ‘Giantess size data’ are compulsory, but you can freely decide whether to input the girl's height as a giantess or the scaling factor.
