Average Weight of Hamsters per Species

How much does a hamster weigh? Well, the weight of a hamster can be affected by how much food you serve and how much exercise it gets. To maintain the right mass for your furry pal, you must know what weight is normal and what is not.

The five most common species of hamsters sold in the market are Syrian hamstersRoborovski hamsters, Campbell’s Russian dwarf hamsters, Winter White dwarf hamsters, and Chinese hamsters. Aside from where the hamster species belong, their average weights can be affected by other factors such as age.

The following are the average weight of hamsters according to species:

Syrian Hamster

Syrian Hamsters can grow up to 18 cm. They have an average weight of about 110 to 200 grams for adults. Newborn Syrian hamster measures 1.5 to 2 cm and weighs around 1.5 to 2 grams.

Roborovski Hamsters

Roborovski hamster (also known as “Robo” or “desert hamster”) has an average length of 2cm at birth and 4.5 to 5cm at adulthood. The normal weight for adult Roborovski hamster is 20 to 25 grams while the newborn only weighs about 1 gram (as light as one paper clip).

Campbell’s Russian Dwarf Hamsters

Winter White Dwarf Hamsters (also known as “Djungarian hamsters”) are 5 to 8 cm in size and usually weigh around 30 grams for adults. Newborn Winter White dwarf hamsters’ average weight is around 1 to 2 grams.

Chinese Hamsters

Chinese hamsters weigh 1.7 grams at birth and 40 to 50 grams as they grow. People often think of Chinese hamsters as dwarf hamsters but they are not really dwarfs.

Weighing a Hamster the Right Way

In measuring the mass of your hamster, you will just need several tools. The following are some of the useful tips to consider in weighing a hamster:

  • You can use a kitchen scale or digital post scale.
  • Use a small box in weighing your hamster because if not, it might just walk off from the scale as soon as you put it there. Measure the weight of the box first then subtract it from the total weight.
  • Use treats like sunflower seeds to keep your hamster in the scale.
  • Weigh the hamster every day or every other day at the same time to measure the changes.

Hamsters don’t meet their required weight possibly because of the quality of food their owners give or due to overfeeding. Make sure to give high-quality food that will meet your hamster’s nutritional needs and feed it with just enough amount of food necessary.

Sometimes, a heavy hamster can be just normal especially if it has reached its maximum size. Actually, some hamsters can be heavier than other animals like a baby deer. If the changes are gradual, it is not usually something to be worried about.
