The Swiss pine is a member of the white pine group, Pinus subgenus Strobus, and like all members of that group, the leaves ('needles') are in fascicles (bundles) of five, with a deciduous sheath. The mature size is typically between 25 metres (82 ft) and 35 metres (115 ft) in height, and the trunk diameter can be up to 1.5 metres (4.9 ft).
