Abstract. We provide estimates for the Hölder exponent of solutions to the Beltrami equation \bard f = \mu d f + \nu\overline{d f}, where the Beltrami coefficients \mu,\nu satisfy |||\mu| + |\nu|||_\infty 2000 Mathematics Subject Classification: Primary 30C62; Secondary 35J25.

Key words: Linear Beltrami equation, Hölder regularity, angular stretching.
