How Much Does a Blueberry Weigh?
As a product of nature, blueberries can vary in size and weight depending on the variety and the conditions they were grown in. Commercial blueberries are grown for both high yield and good-sized juicy fruit, but even so, the sizes which arrive in a shop-bought punnet will all vary by a gram or two.
I did the research which involved weighing a number of fresh blueberries on precision scales and I found that the average small blueberry weighs around 1.5g and a larger blueberry weighs around 2.5-3g each.
When looking at all of the averages it’s safe to say that the weight of an average medium-sized blueberry is around 2g when rounded to the nearest whole number.
The image below shows the size and weight difference between a smaller and larger blueberry, so you can get an idea of how this looks visually.
How Much Does a Cup of Blueberries Weigh?
I measured out a level US cup of blueberries of various sizes and the weight came to 153g (5.4oz).
Obviously, an individual blueberry weight varies and bigger, juicier berries will weigh more, so the cup weight will vary.
A small punnet of supermarket blueberries usually weighs 150g, so you can use this as a guide that a small punnet is equal to a cup.
