Elves are outwardly very similar to humans, standing five to six feet high at maturity (20 years) and having soft skin in a human-like range of tones, with Sylvans tending to be darker and Thelvans having ash-grey or white skin. Their primary distinguishing features from humans are their much lighter frames, pointed ears, and lack of facial or body hair. Upon closer inspection, however, even the "hair" on their heads and brows is not actually hair, but very thin feather-like growths. Their extremely light weight is due to having a hollow bone structure; these traits suggest that the elves may have descended from birds rather than land animals.

Although elves are shorter than most humans initially, they do not stop growing in height after they reach physical and sexual maturity. Because of this, and their extremely long lifespans (often up to 200 years), many elven elders stand well over seven feet tall.
There is virtually no difference in appearance between male and female elves, and in fact their culture holds no difference socially between the sexes aside from the roles played in procreation; attitudes are virtually identical regarding same-sex relationships as heterosexual ones. With an increasing number of elves living in human-dominated cities, same-sex relationships are increasingly seen as desirable among the younger generation who do not want to raise families. A number of elves also have an androgynous persona, which is also normalized by their native language having no grammatical elements of gender.
Despite having very different physiologies, elves do have a limited amount of reproductive compatibility with humans, although the resulting offspring (being of two different species) will themselves be infertile. A sexual relationship between a biologically male elf and a biologically female human is extremely hazardous, however, as the longer gestation period of elves - about twelve months, compared to humans' nine months - will usually result in the mother dying in childbirth. This, coupled with the "half-elf" having a lifespan shorter than their elven parent, but longer than their human one (typically about 120 years), leads many half-elven offspring to have trouble fitting in to whichever society they choose to join; it has been suggested that this is a reason why many adopt the nomadic lifestyle of the adventurer. There has been no evidence suggesting that elves are reproductively compatible with dwarves, gnomes, orcs, or other demihuman or humanoid species; fertilization could hypothetically occur with halflings (due to their physiology being almost identical to that of humans), but such would not result in a child being brought to term, as the mother would die of the strain on her body if a miscarriage did not occur early in the pregnancy.
Elves' hollow bone structure makes them much lighter and more maneuverable than the average human, giving them a +1 bonus to Dexterity; it also makes their bones more vulnerable to breakage, giving them a -1 penalty to Constitution. Half-elves tend to have "chambered" or semi-hollow bones which make them lighter in weight, but do not affect their agility or durability to a significant extent.
