The Ballora blueprint confirms her to be 6.2 feet tall, so I measured the pixels of her body in the picture and found her to be 599 pixels in height
599 pixels = 6.2 feet
So this means
1 pixel = 0.010350584307179 feet
To measure cup size, one must measure the waist below the breast first
The front and back of her waist came to be a total of 122 pixels, now we'll measure the sides and add them up
Each side came to be 69 pixels (nice), which is a total of 260 pixels as her full waist measurement for below the breasts
This can be converted to 2.69115192 feet or 32.29382304 inches
Now, the next step of cup size calculation is to measure the nipple-level of the breast, so right where it horizontally peaks
The front and back of her chest came to 214 pixels
The sides combined calculated to 196 pixels, which brings a total of 410 pixels
This can be converted to 4.24373957 feet or 50.92487484 inches
Cup size is calculated by subtracting the chest size from the below-chest size, leaving a total of 18.6310518 inches
This difference would give her a cup size of R in Canada and the US, or Cup LL in the UK, or Cup W in the EU
