Average Hamster Weights by Breed
Hamster weights vary significantly by breed. Below is a breakdown of the adult weight ranges and key characteristics for common hamster breeds:
1. Dwarf Hamsters (Miniature Breeds)
Campbell’s Dwarf Hamster: 35–60 grams. Features a distinct dark stripe running down its back.
Roborovski Dwarf Hamster (also called "Robos"): 15–30 grams. The smallest common hamster breed, and tends to be more skittish/nervous.
Winter White Dwarf Hamster (also called "Djungarian Hamster"): 30–50 grams. An ideal healthy weight is around 50 grams; if it exceeds 60 grams, dietary control is recommended.
2. Syrian Hamsters (Teddy Bear Hamsters)
Golden Syrian Hamster: 100–200 grams. Males typically weigh 85–140 grams, while females are slightly heavier at 95–150 grams.
Long-Haired Syrian Hamster (including "Teddy Bear" or variants): 150–200 grams. Characterized by long, fluffy fur.
3. Chinese Hamsters
30–50 grams. Unique among hamsters for having a relatively long tail (a rare trait in hamster species).
Hamster Weight Management Tips
Monitoring Frequency: Weigh your hamster once a month. Rapid weight gain is normal for young hamsters (pups) as they grow.
Overweight Standard: If a hamster’s weight exceeds 20% of its breed’s upper limit (e.g., a Winter White Dwarf Hamster over 60 grams), adjust its diet promptly.
Health Risks of Obesity: Excess weight increases the risk of diabetes and heart disease. Increase access to exercise (e.g., ensuring a working exercise wheel) to help maintain a healthy weight.
Note: Weight ranges may vary slightly due to individual differences and care conditions. For a more accurate health assessment, combine weight checks with body length measurements (e.g., Golden Syrian Hamsters typically measure 12–18 cm in length).
