A medium (14 oz) Tim Hortons Original Blend coffee has about 205mg of caffeine, per figures compiled by Caffeine Informer. That is more than most people expect from a standard drip coffee, and it climbs fast with size.
Stronger than its reputation
Tim Hortons brews strong. An extra large Original Blend lands around 330mg, which is over 80 percent of the FDA's 400mg daily context figure in a single cup. If you drink Tims by the extra large, you are effectively topping out your day on one order.
Tim Hortons caffeine by size
| Drink | Size | Caffeine |
|---|---|---|
| Original Blend | Small (10 oz) | 140mg |

These are compiled figures rather than numbers Tim Hortons prints on the menu, so treat them as close estimates. Espresso-based drinks scale by shot count instead.
For context, the FDA cites 400mg of caffeine a day as an amount generally not associated with negative effects in healthy adults. How caffeine affects you depends on your own tolerance and health, so treat these numbers as information, not advice.
