A typical matcha roll slice often lands somewhere around 180 to 320 calories, but only if the slice is roughly 50 to 85 g. A lighter sponge-only slice can be lower. A thick cream-filled bakery slice can be higher.
The search term is messy because “matcha roll” can mean a Japanese-style Swiss roll, a packaged snack cake, a home-baked roll cake or a bakery slice with extra cream. The matcha itself is not the main calorie source. Flour, sugar, eggs, cream, butter or oil decide most of the number.
A practical estimate
| Matcha roll type | Useful estimate | Why it changes |
|---|---|---|
| Thin sponge roll slice, little cream | About 150-220 calories | Lower slice weight and less filling. |
| Standard cream-filled Swiss-roll slice | About 200-300 calories | Usually 60-80 g with cream. |
| Large bakery slice | About 300-450+ calories | Bigger cut, heavier cream, glaze or toppings. |
| Packaged snack roll | Use the label | Brands vary in serving size and filling. |
USDA-derived references are useful for building the range, not for naming one exact matcha-roll value. A sponge creme-filled snack cake reference is around 374 calories per 100 g, while a sweet roll without frosting reference is around 321 calories per 100 g. A matcha Swiss roll with cream often sits in that neighborhood, then moves up or down with filling and portion size.
How to calculate your slice
- Weigh the slice in grams.
- Choose a matching reference: sponge cake, cream-filled cake roll or a brand label.
- Multiply calories per 100 g by your slice weight, then divide by 100.
- Add separately for glaze, chocolate, red bean paste or extra cream.
Example: if your slice weighs 70 g and you use a 374 kcal per 100 g sponge-cake reference, the estimate is about 262 calories. That is more useful than guessing by slice width because cream thickness changes the weight quickly.
What matcha changes
Matcha mostly changes color, flavor and a small amount of caffeine. It does not turn a cake roll into a low-calorie food. For plain powder context, use Sailtik’s matcha calorie guide. For broader nutrition wording, see matcha nutrition, calories, sugar and carbs.

FAQ
Is a matcha roll healthier than a regular Swiss roll?
Not automatically. Calories still come mainly from sponge, sugar and cream.
How many calories are in one bakery slice?
Weigh it if you can. A thick slice can easily be twice the weight of a thin home-baked slice.
Does matcha add many calories?
No. In a roll cake, matcha powder is usually a small ingredient compared with flour, sugar and cream.
