How this was calculated
For a German Shepherd we use the large-breed growth curve (matures around 18 months): adult weight ≈ current weight ÷ the fraction of adult weight a large breed reaches at this age. Typical adult weight (50–90 lb) is from the AKC breed standard. The gauge shows where your prediction lands against the breed-typical adult range.

About our figures →German Shepherd growth chart
Typical German Shepherd weight from 8 weeks to fully grown, for males and females. A healthy German Shepherd tracks near these figures — individuals sit up to ~10–15% either side.

German Shepherd growth, explained
German Shepherds are a large breed, so they follow the large-breed growth curve. AKC: males 65–90 lb, females 50–70 lb. Slow, steady growth to ~18 months — don’t rush it. Most reach close to their adult weight by around 18 months, then continue to firm up in muscle and chest for a while after.
To predict an adult weight we divide your puppy’s current weight by the fraction of adult weight a large breed has typically reached at that age. Typical adult weight (50–90 lb) is from the AKC breed standard. The result is an estimate with a likely range — genetics and nutrition move individual dogs up or down. If your German Shepherd looks heavier or lighter than the breed-typical band, your vet is the best person to check.
