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 chart

Typical Great Dane weight from 8 weeks to fully grown, for males and females. A healthy Great Dane tracks near these figures — individuals sit up to ~10–15% either side.

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.

Great Dane weight questions

How big do Great Danes get?
A typical adult Great Dane weighs about 110–175 lb. AKC: males 140–175 lb, females 110–140 lb. Controlled, slow growth to ~2 years protects the joints.
What should a Great Dane weigh by age?
See the Great Dane growth chart above for weight at 8 weeks through to adult. As a guide, a giant-breed puppy is roughly half its adult weight by about 6 months.
Do male and female Great Danes weigh differently?
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.
When is a Great Dane fully grown?
Great Danes are a giant breed and usually finish growing around 24 months, though they may keep filling out a little after that.
How accurate is this for a Great Dane?
Within about 10–15% if your puppy is a typical Great Dane. Crossbreeds, runts and big-boned individuals vary more. It’s an estimate — your vet can assess your individual dog.
