An approximate guide to the yield of whole blueberries in US cups from common retail container sizes (US dry pint and quart).
Whole Blueberries (Container Size)
Approximate US Cups
Approximate Weight (oz / g)
1 US dry pint container
~2 cups
~10-12 oz / ~280-340 g
1 US dry quart container
~4 cups
~20-24 oz / ~560-680 g
1 "clamshell" (often 6 oz by weight)
~1 to 1 1/4 cups
6 oz / ~170 g
1 "clamshell" (often 11 oz by weight / "pint")
~2 cups
11 oz / ~312 g
Important Considerations for Blueberry Yield:
Berries are often sold in **US dry pint** or **US dry quart** containers, which are measures of volume, not weight (though some clamshells are sold by weight).
1 US dry pint ≈ 2.3 US cups if the berries were perfectly round and packed with no air, but due to air space, a dry pint container of blueberries typically holds about **2 US cups** of berries.
Similarly, a US dry quart container typically holds about **4 US cups** of blueberries.
The actual number of cups can vary slightly based on berry size and how tightly they are packed in the retail container.
Weight per cup also varies: 1 US cup of blueberries weighs approximately 5-6 ounces (140-170 grams).
If a recipe calls for a specific volume (cups) or weight (oz/g) of blueberries, it's best to measure them out from the container.
