how much caffeine in a can of coke

A standard 12 oz (355 ml) can of regular Coca‑Cola contains about 34 mg of caffeine.

Quick Scoop

• A 12 oz / 355 ml can of Coke: around 32–34 mg caffeine (brands and regions vary slightly).

• A 330 ml can (common outside the US): about 32–35 mg caffeine.

• Diet Coke usually has more caffeine than regular Coke (roughly 42–46 mg per 12 oz).

• Caffeine‑free Coke variants have 0 mg of caffeine.

How that compares

• Typical coffee (8 oz): about 95–200 mg caffeine.

• Tea (8 oz): roughly 20–70 mg depending on type and brew.

• So a can of Coke has much less caffeine than a cup of coffee, and is in the same ballpark as a mild tea.

Mini note on daily limits

Most healthy adults are often advised to stay at or below about 400 mg of caffeine per day , so it would take many cans of Coke alone to hit that, but sugar and overall diet are also important to consider.
