Whether you prefer fresh raw blueberries or frozen unsweetened blueberries, this calculator helps you determine exactly how much fiber you're getting from your serving. Fresh and frozen blueberries have similar fiber content, though frozen berries may have slightly different water content.

How to Measure Consistently
- Weigh blueberries for the most accurate fiber calculation, as volume measurements can vary based on berry size.
- One cup (about 148g) of fresh blueberries provides approximately 3.5-4 grams of fiber.
- Use a kitchen scale for precise measurements, especially if tracking fiber for specific health goals.
- For frozen blueberries, measure while still frozen if using in recipes, or after thawing if eating directly.
- If using volume measurements, pack blueberries gently into the measuring cup for consistency.
What Changes the Number
- Fresh vs frozen: fresh and frozen unsweetened blueberries have similar fiber content per gram. Frozen berries may have slightly different water content.
- Berry size: larger blueberries may have slightly different fiber-to-weight ratios than smaller berries, but the difference is minimal.
- Preparation: whole blueberries have more fiber than pureed or juiced blueberries, as processing can remove some fiber.
- Ripeness: fully ripe blueberries may have slightly different water content, but fiber per gram remains similar.
- Storage: very fresh blueberries may have slightly different water content than older berries, but fiber content is stable.
