Coffee often has more caffeine per typical cup, but matcha depends strongly on how much powder is used. A small matcha may be lower in caffeine than brewed coffee. A stronger matcha latte can move closer to coffee.
The best choice depends on serving size, timing and personal caffeine sensitivity.
Quick answer
A typical brewed coffee is often the higher-caffeine choice. Mayo Clinic lists brewed coffee at about 96 mg of caffeine per 8-ounce serving, while the FDA describes an 8-ounce cup of coffee as commonly containing about 80 to 100 mg. Those are examples, not a guarantee for every coffee.
Matcha is different because you drink powdered green tea rather than steeping leaves and removing them. A review of matcha composition reported caffeine values of about 18.9 to 44.4 mg per gram of matcha powder. That means the caffeine in a matcha drink depends heavily on whether the serving uses a small amount of powder or a stronger scoop.
In practical terms:
- coffee often has more caffeine per typical cup;
- a small matcha may be lower than brewed coffee;
- a strong matcha latte can be closer to coffee; and
- either drink can matter if caffeine affects your sleep.

How much caffeine is in coffee?
Coffee caffeine varies by bean, roast, grind, brewing method and serving size. An “8-ounce coffee” is also not always the same as the mug or café drink someone actually drinks.
Mayo Clinic gives about 96 mg caffeine for an 8-ounce brewed coffee example. FDA gives a similar practical range, saying an 8-ounce cup of coffee usually has about 80 to 100 mg caffeine.
Use those numbers as everyday anchors, not exact values. Espresso drinks, larger mugs, cold brew, concentrated coffee and multi-shot café drinks can be very different from a simple 8-ounce brewed coffee.
How much caffeine is in matcha?
Matcha is powdered green tea made from Camellia sinensis. NCCIH describes green tea as containing caffeine, and matcha composition research describes matcha as a powdered form of green tea.
The important difference is that matcha caffeine is tied to the amount of powder used. Kochman and colleagues reported caffeine values in matcha of about 18.9 to 44.4 mg per gram of powder. A drink made with more powder will generally contain more caffeine than one made with less powder, although products still vary.
As a rough illustration from that reported range:
- 1 gram of matcha powder could contribute roughly 19 to 44 mg caffeine;
- 2 grams could contribute roughly 38 to 89 mg; and
- stronger preparations can climb from there.
Those calculations are not a label claim for every matcha. They show why “matcha vs coffee” is really a serving-size question.
Why matcha caffeine depends on powder amount
Brewed tea depends on leaves, water, steep time and extraction. Matcha adds another factor: the amount of powder in the cup.
Because the powder is whisked into the drink, a small difference in scooping can change the caffeine meaningfully. A lightly prepared matcha can sit well below a typical coffee example. A café-style matcha latte made with a larger powder portion can be much closer to coffee.
Composition studies also show that green-tea products vary. That variation is one reason it is better to treat caffeine numbers as approximate unless the product label gives a tested amount.
For preparation basics, the Tea Brewing Guide can help with tea type and serving style. If you are measuring loose tea rather than matcha powder, see how much loose-leaf tea to use per cup.
Matcha latte vs brewed coffee
A matcha latte is not automatically low-caffeine or high-caffeine. The milk does not create caffeine; the matcha powder does.
A small latte made with a modest amount of matcha may contain less caffeine than a standard brewed coffee. A stronger latte made with more powder can be closer to coffee, especially if the coffee comparison is a smaller or weaker cup.
This is why café menus can be hard to compare. One place may use a small amount of matcha powder, while another may use a stronger serving. If caffeine matters to you, the most useful question is often “how much matcha powder is in this drink?” rather than “is matcha lower than coffee?”
Matcha vs green tea
Matcha and brewed green tea both come from true tea, but they are prepared differently.
Brewed green tea is usually made by steeping leaves in water, then removing the leaves. Mayo Clinic lists about 28 mg caffeine for an 8-ounce brewed green tea example, while FDA describes green or black tea as commonly ranging around 30 to 50 mg per 8-ounce serving.
Matcha is powdered green tea, so the amount of powder used has a bigger role. It may contain more caffeine than a typical brewed green tea serving, especially when prepared strongly, but it still varies by product and serving size.

Which is better if you are sensitive to caffeine?
If you are sensitive to caffeine, the better choice is the one you can size and time more predictably.
Coffee may be easier to estimate when you know the serving size and type. Matcha may be easier to adjust because you can use less powder, but that only helps if you actually measure or keep the serving consistent.
FDA notes that people vary in their caffeine sensitivity and in how quickly they eliminate caffeine. That means one person may tolerate a morning coffee easily, while another may feel jittery from a smaller matcha.
Practical options include:
- choosing a smaller serving;
- using less matcha powder;
- avoiding late-day caffeine;
- checking labels when caffeine amounts are listed; and
- keeping your routine consistent enough to notice patterns.
Do not treat matcha as caffeine-free. It is still green tea, and green tea contains caffeine.
What about bedtime?
If caffeine affects your sleep, timing matters more than whether the drink feels gentle.
EFSA notes that single doses of 100 mg caffeine may affect sleep duration and patterns in some adults, particularly when consumed close to bedtime. Drake and colleagues studied a much larger 400 mg caffeine dose and found sleep disruption when it was taken 0, 3 or 6 hours before bedtime.
That 400 mg study should not be read as a normal matcha serving. It does support the broader point that meaningful caffeine late in the day can affect sleep for some people.
A practical starting point is to avoid substantial caffeine within about 6 hours of bedtime, then adjust based on your own sleep. For more detail, see how late is too late for coffee or tea?.
Practical takeaway
Matcha is not automatically “less caffeinated” than coffee, and coffee is not automatically the wrong choice.
Use these rules of thumb:
- coffee often has more caffeine per typical cup;
- matcha depends on grams of powder;
- a small matcha may be lower than brewed coffee;
- a stronger matcha latte can be closer to coffee;
- brewed green tea is often lower than both coffee and stronger matcha; and
- timing matters if caffeine affects your sleep.
If you want the calmer, more useful answer, compare the actual serving in front of you: cup size, powder amount, preparation strength and time of day.
