The short answer: A single blueberry typically weighs about 1 to 2 grams (0.04 to 0.07 ounces), so they are usually measured by the cup.
Blueberry weight by type
Blueberries are tiny, so individual weights are small and vary by variety. Here are some common measures and their typical weights.
| Type (example) | Typical weight |
|---|---|
| Wild (lowbush) blueberry | about 0.3-0.5 g |
| Cultivated (highbush) blueberry | about 1-2 g |
| Jumbo cultivated blueberry | about 2-3 g |
| Cup of blueberries | about 140-150 g (5 oz) |
What affects blueberry weight
- Variety. Wild blueberries are much smaller than cultivated highbush berries.
- Size grade. Premium jumbo berries can weigh two to three times a standard one.
- Ripeness. Fully ripe berries hold more juice and weigh slightly more.
- Water content. Fresh berries are heavier than slightly dried ones.
- Growing conditions. Rainfall and climate affect how plump berries grow.
- Measuring by cup. Cups give a more reliable figure than counting single berries.
How blueberry weight compares
A single blueberry weighs about the same as a small paperclip or a single dried pea, while a whole cup is closer to a medium apple (around 145 grams).
