With an average length of {{Convert|45|cm|abbr=on}} and an average height of {{Convert|30|cm|abbr=on}}, the Java mouse-deer is the smallest [[Neontology|extant]] (living) even-toed ungulate, as well as the smallest extant ungulate.<ref name=eof5/><ref name=erythrocytes9/>

The weight of the Java mouse-deer ranges from {{Convert|1|to|2|kg}}, with females falling on the lower end of the spectrum. It has an average tail length of about {{Convert|5|cm|abbr=on}}. The Java mouse-deer is also considered to be the most primitive [[ruminant]] based on its behaviour and the [[fossil]] record, thustherefore it provides the living link between ruminants and non-ruminants.<ref name=animalrecs10>Carwardine, M., & London, E.
