From our viewpoint on earth, the biggest and brightest star (apart from our sun) is Sirius. This has the largest apparent magnitude in our skies.

Another measure is luminousity, where we consider which would be the brightest stars from a set distance. This one goes to a star called R136a1, which is a blue (very hot) hypergiant. Its also the most massive star discovered to date.

The biggest known Star in terms of volume is a red Hypergiant called VY Canis Majoris. Its radius is around 2000 times bigger than our suns. If it were in our solar system, the surface would extent to the orbit of Saturn.
