A standard can of regular Coca‑Cola contains about 39 g of sugar , which is roughly 9–10 teaspoons in a 12 oz (355 ml) can.

Quick Scoop

  • A 12 oz (355 ml) can of Coke: 39 g sugar.
  • That’s about 9–10 teaspoons of sugar in one can.
  • A 330 ml can (common in the UK) is listed at about 35 g sugar , or around 9 teaspoons.

How that compares to daily limits

  • UK NHS guidance suggests adults have no more than 30 g of “free sugar” per day , so a single 330 ml can already exceeds that.
  • A 12 oz can (39 g) is more than the full recommended daily added sugar limit for most adults based on common heart‑health guidelines.

Mini perspective

Imagine spooning almost 10 teaspoons of white sugar into a single glass – that’s essentially what you’re drinking with one can of Coke. People often share visuals and forum posts showing piles of sugar next to the can to make this easier to picture and spark discussion about soft drink habits.

TL;DR: A can of Coke (12 oz) has about 39 g of sugar , or 9–10 teaspoons , which alone can meet or exceed an adult’s entire recommended daily added sugar intake.
