How this was calculated
For a Pit Bull (American Pit Bull Terrier) we use the medium-breed growth curve (matures around 16 months): adult weight ≈ current weight ÷ the fraction of adult weight a medium breed reaches at this age. Pit Bull (American Pit Bull Terrier) has no kennel-club standard, so the 30–60 lb range is indicative for the standard size — pick the size that matches your pup. The gauge shows where your prediction lands against the breed-typical adult range.
