People often ask how many ounces are in a glass of water. The answer depends on the country and type of glass, but the common standard is about 8 ounces (≈240 ml). Some glasses are smaller at 6 oz, while large tumblers may hold 12–16 oz.
Knowing this helps you track hydration more accurately, especially if you follow the “8 glasses a day” rule.
