How much less alcohol does light beer typically have compared to regular beer?

Light beer is designed to have fewer calories and less alcohol than regular beer, often by reducing the amount of fermentable sugars used in the brewing process or by water dilution after fermentation. Typically, light beers have an alcohol by volume (ABV) that is about 10% lower than that of regular beers. For regular beers, the average ABV is around 5% to 6%, while light beers generally range from about 3% to 4.5% ABV. This reduction in alcohol content is an important reason why many people choose light beers—it's perceived as a lighter, lower-impact option for those looking to moderate their alcohol intake.
