Different methods are used for different stars. For stars that are relatively near to us, the parallax method is used. This means that - as Earth moves around the Sun, and changes its position by about 300 million kilometers (2 AU) within half a year (and then back again) - the apparent position of the observed star will change. The larger this angle, the nearer the star is to us. For more details, do some reading (e.g., in the Wikipedia) about the parallax method. For other methods (for stars or galaxies that are further away), check the Wikipedia article on "cosmic distance ladder".

What is used to determine the distance to nearby stars?
They use trigonometry to determine the distance to nearby stars. They measure the star's positions at one point in time, and again six months later, calibrating against the backdrop of the far distant stars. The nearby stars will show a parallax shift in position, so they calculate a triangle, with the Earth at two points, and the base 186 million miles long. The star is the third point on the triangle, and it is simple trigonometry from there to figure out the distance.
