For a lot of Canadians, "a double-double" is the unit of coffee. But Tim Hortons caffeine varies more than the ritual suggests. A medium Original Blend has about 205 mg of caffeine, a small French Vanilla about 60 mg, and an extra-large steeped tea about 210 mg. Which one you order changes your day's total by more than a coffee's worth.
Below is how much caffeine is in Tim Hortons coffee, tea and iced drinks by size, using the same values as the Caffeine vs Water drink catalog. The brewed coffee figures most sources use trace back to caffeine data Tim Hortons published in 2008. Treat them as solid estimates, not measurements of your cup.
Tim Hortons coffee caffeine by size
| Drink | Small ~10 oz / 286 ml | Medium ~14 oz / 425 ml | Large ~19 oz / 563 ml | XL ~23 oz / 678 ml |
|---|---|---|---|---|
| Original Blend | 140 mg | 205 mg | 270 mg | 330 mg |
| Dark Roast | 130 mg | 195 mg | 260 mg | 315 mg |
| Decaf | 6 mg | 9 mg | 12 mg |
A double-double has exactly the same caffeine as a black coffee of the same size: cream and sugar add calories, not caffeine. Dark Roast has a little less than Original Blend, because darker-roasted beans are less dense, so the same scoop holds slightly less coffee.
How Tim Hortons compares with Dunkin' and Starbucks
| Medium brewed coffee | Size | Caffeine |
|---|---|---|
| Tim Hortons Original Blend, Medium | 14 oz | 205 mg |
| Dunkin' Hot Coffee, Medium | 14 oz | 210 mg |
| Starbucks Pike Place, Tall | 12 oz | 235 mg |
| Starbucks Pike Place, Grande | 16 oz | 310 mg |
Tim Hortons and Dunkin' are almost identical size for size. Starbucks brews stronger: its 12 oz Tall has more caffeine than a Tims 14 oz medium. Full breakdowns are in Dunkin' caffeine by size and Starbucks caffeine by drink and size. For the UK, see Costa Coffee caffeine by size.
Tim Hortons steeped tea caffeine
| Size | Volume | Caffeine |
|---|---|---|
| Small | ~10 oz / 286 ml | 90 mg |
| Medium | ~14 oz / 425 ml | 125 mg |
| Large | ~19 oz / 563 ml | 175 mg |
| Extra large | ~23 oz / 678 ml | 210 mg |
Tims steeped tea is brewed strong, so it has far more caffeine than a tea bag in a mug at home (about 47 mg per 8 oz). An XL steeped tea has slightly more caffeine than a medium Original Blend coffee. If you switched to tea to cut back, the size matters more than the leaf. More on this in caffeine in tea.
Iced Capp, iced coffee and specialty drinks
| Drink | Small | Medium | Large |
|---|---|---|---|
| Iced Capp | 110 mg | 140 mg | 170 mg |
| Iced Coffee (Canada) | 60 mg | 130 mg | 160 mg |
| French Vanilla | 60 mg | 80 mg | 110 mg |
| Americano (U.S.) | 95 mg | 140 mg | 170 mg |
| Espresso shot (U.S.) | 45 mg | ||
The Iced Capp is often treated as a treat rather than a coffee, but a medium has about 140 mg, more than a small Original Blend. French Vanilla is made from a sweet powdered mix that contains a little coffee, so it's one of the milder caffeinated drinks on the menu. Tim Hortons iced coffee is also much lighter than Dunkin's, where a medium iced has about 297 mg.
Recipes and sizes differ between Canada and the U.S., so the espresso and Americano values above are U.S. figures. A Tim Hortons espresso shot, at about 45 mg, is one of the lightest among the big chains.
The strongest and weakest Tim Hortons orders
| Most caffeine | Caffeine | Least caffeine | Caffeine |

| Medium Original Blend | 205 mg | Medium French Vanilla | 80 mg |
When to have your last Tims of the day
With a typical 5.5-hour half-life, a medium Original Blend (205 mg) takes about 11.5 hours to drop below 50 mg, the level most sleep research treats as low enough not to matter. A large (270 mg) takes about 13.5 hours and an XL (330 mg) about 15.5 hours. A 2023 meta-analysis of 24 studies recommended stopping a regular coffee at least 8.8 hours before bed.

| Half-life | 1 h | 3 h | 6 h | 9 h | 12 h | 24 h |
|---|---|---|---|---|---|---|

| 5.5 h | 183 | 145 | 99 | 68 | 47 | 10 |

mg of active caffeine, hours after one 205 mg drink.
So a medium on the drive home at 4 pm still leaves about 90 mg at 11 pm for a typical adult; a medium decaf leaves almost nothing. Try your own order in the caffeine bedtime calculator, or see the full cutoff table in when to stop drinking coffee before bed.
In Caffeine vs Water, a medium Tims is already in the catalog, so the app can show how much room you have left before bed ("You can still have ~60 mg") and when your next one would still leave you under target.
