Hamster Age Calculator (Hamster Years to Human Years)

Your hamster's age in human years and life stage, for Syrian, Roborovski, winter white, Campbell's and Chinese hamsters.

A hamster ages roughly 30–40 times faster than a person. A 1-year-old Syrian hamster (average lifespan 2.5 years) is about 1 × 79 ÷ 2.5 = 32 in human years; a 2-year-old is about 63.

Questions

How long do hamsters live?

Syrian and Chinese hamsters usually live 2–3 years, Roborovski dwarfs about 3 years, and winter white and Campbell's dwarfs 1.5–2 years, with good care sometimes a little longer.

How old is my hamster in human years?

Divide its age by its species' lifespan and multiply by a human lifespan of about 79 years. A 6-month-old Syrian is about 16 human years.

How can I tell how old my hamster is?

Young hamsters have bright eyes and dense coats and are very active. Seniors thin out, lose weight, sleep more and may develop cloudy eyes. A vet can only estimate.

When is a hamster considered old?

From about 18 months for Syrians and 12–15 months for winter white and Campbell's dwarfs.

Limitations

A lifespan-proportional estimate; individual hamsters vary.
