How Much Caffeine Is in Red Bull? Every Can Size (8.4 to 20 oz)
How much caffeine is in Red Bull? It depends on the can. Red Bull uses the same recipe across its cans, so the caffeine goes up with the size of the can. The classic 8.4 fl oz can has about as much caffeine as a cup of home-brewed coffee, which is less than most of the big 16 fl oz energy drinks. This guide shows the caffeine in every Red Bull can size, how it compares with other energy drinks, and the Red Bull packs we stock.
Red Bull Caffeine by Can Size
| Can size | Caffeine per can | Caffeine per fl oz | Shop |
|---|---|---|---|
| 8.4 fl oz | 80mg | about 9.5mg | 24-pack |
| 12 fl oz | 114mg | about 9.5mg | 12-pack / 24-pack |
| 16 fl oz | 151mg | about 9.4mg | 12-pack |
| 20 fl oz | 198mg | about 9.9mg | 12-pack |
