How this was calculated
For a Great Dane we use the giant-breed growth curve (matures around 24 months): adult weight ≈ current weight ÷ the fraction of adult weight a giant breed reaches at this age. Typical adult weight (110–175 lb) is from the AKC breed standard. The gauge shows where your prediction lands against the breed-typical adult range.

Great Dane growth, explained
Great Danes are a giant breed, so they follow the giant-breed growth curve. AKC: males 140–175 lb, females 110–140 lb. Controlled, slow growth to ~2 years protects the joints. Most reach close to their adult weight by around 24 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 giant breed has typically reached at that age. Typical adult weight (110–175 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 Great Dane looks heavier or lighter than the breed-typical band, your vet is the best person to check.

- Yes — male Great Danes run about 140–175 lb and females about 110–140 lb, so the growth chart above shows a separate line for each. Individuals overlap.
