Research results of studies of the seasonal, interannual, landscape and biotopic changes of the dimension structure of small rodent community inhabiting in the forest complexes of the northern part of the Republic of Belarus were presented. The average measures of body length and weight of small rodents were stated. The seasonal and annual biotopic changes of various species distribution according to the biomass indices were presented. Correlation calculation between body weight and length of small rodents and their percentage number in the structure of small rodent associations according to the abundance and biomass indices were analyzed. Dimension parameters of various small rodent species in pre- and post-reproduction period in relation to landscape and habitat related differences of woodlands were assessed. It was revealed that bank vole (Clethrionomys glareolus), being medium sized, had the biggest percentage in total rodent density and biomass. Species with high (yellow-necked mouse (Apodemus flavicollis), field vole (Microtus agrestis) and forest dormouse (Dryomys)) and low (harvest mouse (Micromys minutus), birch mouse (Sicista)) values of body mass formed the minor part of total rodent biomass. Differences in body size of almost all rodent species were revealed. Significant correlations between the average body mass of various species and their portions in the total density and biomass of all rodent species were not statistically proved
