A method for controlling valve timing is provided for an engine including continuous variable duration (CVVD) device disposed on both intake valve and exhaust valve sides respectively. The method may include: classifying control regions into first, second, third, fourth, and fifth control regions based on engine load and speed; applying a maximum duration to an intake valve and controlling a valve overlap in a first control region, applying the maximum duration to the intake valve and exhaust valve in the second control region; controlling a manifold absolute pressure (MAP) of an intake manifold to be maintained consistently in the third control region; controlling a throttle valve to be fully opened, advancing an intake valve closing (IVC) timing, and controlling an exhaust valve closing (EVC) timing to after top dead center in the fourth control region; and controlling a wide open throttle valve (WOT) and retarding the intake valve closing in the fifth control region.
