The uncertainty principle states that the product of the uncertainties in position and momentum is at least as large as a fixed constant. Therefore, if the uncertainty in position is reduced by a factor of two, the uncertainty in momentum must increase to compensate, hence it doubles.

According to the Uncertainty Principle, If the Uncertainty in Position
