It is hard to guess what a Bank vole weights. But we have the answer:
An adult Bank vole (Myodes glareolus) on average weights 20 grams (0.04 lbs).
The Bank vole is from the family Cricetidae (genus: Myodes). It is usually born with about 1 grams (0 lbs). They can live for up to 4.83 years. When reaching adult age, they grow up to 10.6 cm (0′ 5″). On average, Bank voles can have babies 3 times per year with a litter size of 4.
As a reference: An average human weights in at 62 kg (137 lbs) and reaches an average size of 1.65m (5′ 5″). Humans spend 280 days (40 weeks) in the womb of their mother and reach around 75 years of age.

The bank vole (Myodes glareolus; formerly Clethrionomys glareolus) is a small vole with red-brown fur and some grey patches, with a tail about half as long as its body. A rodent, it lives in woodland areas and is around 100 millimetres (3.9 in) in length. The bank vole is found in much of Europe and in northwestern Asia. It is native to Great Britain but not to Ireland, where it has been accidentally introduced, and has now colonised much of the south and southwest.The bank vole lives in woodland, hedgerows and other dense vegetation such as bracken and bramble. Its underground chamber is lined with moss, feathers and vegetable fibre and contains a store of food. It can live for eighteen months to two years in the wild and over 42 months in captivity and is mostly herbivorous, eating buds, bark, seeds, nuts, leaves and fruits and occasionally insects and other small invertebrates. It readily climbs into scrub and low branches of trees although it is not as versatile as a mouse. It breeds in shallow burrows, the female rearing about four litters of pups during the summer.
