Grape Weight & Calorie Chart For Various Serving Sizes

This chart is based on an average-sized grape of 7g per grape (either green or red) and assuming a calorie count of 5kcal per 7g grape (as per MyFitnessPal).

I have worked out each serving size based on these averages and for various portion sizes so you can work out the weights and calories per portion size:

How Many Grapes are in a Serving?

As part of the ‘5 a day’ recommendation, a portion of grapes is considered to be a handful of grapes of any size.

The handful of seedless grapes in this image contains 16 average to large-sized green grapes which weighed 130g (without the stalks).

A handful of smaller red grapes contained 20 grapes.

What Does a Punnet of Grapes Weigh?

In greengrocers and some supermarkets, grapes are usually sold loose at a certain cost per kilogram or pound.

Most supermarkets sell grapes packaged up in a punnet of a specific weight which is normally 500g in weight (including stalks, but excluding packaging).

The number of grapes in the pack will vary depending on the size of the grapes and also the juice content which can depend on the grape-growing season.


How Many Grapes are in a Cup?

If you prefer to measure by the cup, then this section will help you to work out the weight and amount of grapes per cup.

I filled a US cup with grapes of various sizes and a full cup of grapes weighed 160g/5.6oz/0.16kg/0.35lb, this was equal to a total of 23 grapes.

A cup of small grapes would contain around 30 grapes and a cup of large grapes would contain around 16 grapes in total.

How Many Grapes are in 100g?

Based on an average-sized grape weight of 7g, there are around 14-15 grapes in a 100g portion of red or green seedless grapes.


How Many Grapes are in a Pound of Grapes?

Based on an average grape size of 7g (0.25oz), there are around 65 grapes in a pound of grapes (without stalks).


Equipment and information used for this article

I used precision scales that weigh to 0.01 of a gram which is regularly calibrated with a 100g weight. For more information see my recommended weighing scales here.
