Natural lifespan of Elves is between a few hundred to over a thousand years. But due to hazards of living in Tamriel, dangers and diseases etc... they don't live that long. As for exact value there are contradicting information here and there.

Doesn't matter because Magic, Alchemy and Blessings can extend lifespan regardless if you're an Elf or Human in Elder Scrolls.
