Quick answer: How many calories in a strawberry? A medium strawberry (about 12 grams) contains roughly 4 calories, and a full cup of sliced strawberries (about 150g) contains around 48 calories. Strawberries are one of the lowest-calorie fruits you can eat, which is part of why they’re such a popular choice for anyone watching their intake without wanting to give up something sweet.
This guide breaks down exactly how many calories are in a strawberry by size and serving, plus the full nutrition profile, so you know exactly what you’re getting.
Strawberry Calories Per 100g
Nutrition labels and databases most commonly reference food by 100-gram servings, since it’s the easiest way to compare foods on a level playing field. Per the USDA FoodData Central database, raw strawberries contain approximately:
- 32 calories per 100g
- 7.7g carbohydrates
- 2g dietary fiber
- 4.9g natural sugar
- 0.7g protein
- 0.3g fat
This makes strawberries one of the lowest-calorie-density fruits available — for comparison, most fruits fall somewhere between 40-90 calories per 100g.
How Many Calories in a Strawberry by Serving Size
Since most people don’t measure strawberries in exact grams, here’s how the calorie count breaks down by common real-world servings:
| Serving | Weight | Calories |
|---|---|---|
| 1 small strawberry | ~7g | ~2 calories |
| 1 medium strawberry | ~12g | ~4 calories |
| 1 large strawberry | ~18g | ~6 calories |
| 1 cup, whole | ~150g | ~48 calories |
| 1 cup, sliced | ~166g | ~53 calories |
| 10 strawberries (medium) | ~120g | ~38 calories |
These figures are approximate, since strawberry size varies naturally by growing conditions and variety — but they’re close enough for everyday tracking purposes.
Full Nutrition Facts
Beyond calories, strawberries carry a genuinely strong nutrition profile for how few calories they contain:
- Vitamin C: About 59mg per 100g — roughly 65% of the daily recommended value in a single serving, more than an equivalent amount of orange.
- Fiber: Around 2g per 100g, supporting digestion and helping you feel fuller for longer.
- Manganese: A useful contribution toward daily needs, supporting metabolism and bone health.
- Antioxidants: Strawberries are rich in anthocyanins and ellagic acid, plant compounds linked to reduced oxidative stress.
- Water content: Strawberries are roughly 91% water, which contributes to their low calorie density and makes them a hydrating snack choice.
How Strawberries Compare to Other Berries
If you’re calorie-comparing across fruit options, here’s how strawberries stack up against other common berries (per 100g):
| Berry | Calories per 100g |
|---|---|
| Strawberries | ~32 |
| Raspberries | ~52 |
| Blueberries | ~57 |
| Blackberries | ~43 |
| Cranberries (raw) | ~46 |
Strawberries consistently come in as one of the lowest-calorie berry options, while still delivering a strong vitamin C and fiber profile.
Fitting Strawberries Into a Calorie-Controlled Diet
Because of their low calorie density and high water/fiber content, strawberries are a genuinely easy food to build into a calorie-conscious diet without much planning:
- As a snack: A full cup of sliced strawberries for under 50 calories is a filling, satisfying option compared to many processed low-calorie snacks.
- In smoothies: Adding natural sweetness and fiber without a large calorie cost.
- As a dessert substitute: Strawberries with a small amount of yogurt or dark chocolate can satisfy a sweet craving for meaningfully fewer calories than traditional dessert options.
- Watch the additions: The calorie count changes fast once you add sugar, cream, or chocolate coating — a plain cup of strawberries and a chocolate-covered strawberry dessert are very different calorie totals.
Frequently Asked Questions
How many calories are in 10 strawberries?
Ten medium strawberries (about 120g) contain roughly 38 calories, though this varies somewhat depending on the actual size of the berries.
Are strawberries good for weight loss?
Strawberries can fit well into a weight-loss-focused diet due to their low calorie density, high water content, and fiber, which supports feeling full. They’re not a “fat-burning” food on their own, but they’re a genuinely useful low-calorie option for satisfying a sweet craving.
How many calories are in a cup of strawberries?
A cup of whole strawberries (about 150g) contains roughly 48 calories, while a cup of sliced strawberries (slightly more dense due to less air between pieces) comes to around 53 calories.
Do frozen strawberries have the same calories as fresh?
Yes, frozen strawberries have essentially the same calorie and nutrient content as fresh ones, since freezing doesn’t meaningfully change the nutritional profile — just be mindful of any added sugar in some frozen or processed strawberry products.
How many calories are in strawberries with sugar added?
Adding sugar significantly changes the total — even a tablespoon of added sugar adds roughly 48 calories on its own, potentially doubling or more the calorie count of an otherwise low-calorie serving.
The Bottom Line
So, how many calories in a strawberry? A medium strawberry contains only about 4 calories, and even a generous cup-sized serving stays under 50 — making strawberries one of the most calorie-efficient ways to satisfy a sweet craving while still getting real fiber, vitamin C, and antioxidants. The calorie count stays low as long as you keep additions like sugar or cream in check.
