Quick answer

For the lowest calories and carbs, Michelob Ultra is your pick. If you want a crisp, cold refreshment, Coors Light delivers. For a classic light beer with more flavor and half the carbs of Bud Light, Miller Lite is the balanced choice.

What sets these light beers apart?

All three are American light lagers with the same 4.2% ABV, but they differ in calories, carbs, and the story behind each brew. Miller Lite pioneered the light beer category in 1975, while Coors Light brought Rocky Mountain spring water and a cold-certified label in 1978. Michelob Ultra arrived in 2002, targeting drinkers who want a low-carb option without sacrificing flavor.
