We present the Hipparcos parallaxes and resulting radii for 10 white dwarfs in visual binaries or common proper motion pairs and 11 field white dwarfs. Hipparcos parallaxes, with uncertainties approaching 1 milliarcsec for brighter stars, will have significant impact on a broad range of astrophysical fields. Here, we use the results to directly test the white dwarf mass-radius relation. In general, our results support its predictions and our understanding of stellar degeneracy.
