Spinach Weights, Calories & Servings (with calculator & Charts)

In this article, I’ve put together a calculator and charts so you can quickly work out the exact weights, servings, and calories of various portions of spinach.

How Much Spinach is in a Serving?

A serving of spinach is one US cup/30g/1.1oz of uncooked spinach or two US cups/60g/2.1oz of uncooked spinach which is then steamed. A 30g (1.1oz) serving of uncooked spinach contains 7 calories (in kcal).

Because spinach can be eaten raw or cooked it’s important to know the weight differences between the two because spinach releases water and shrinks when cooked. For more information on before and after cooking, weights see the section further down this page.

Spinach Serving Calculator

If you need to plan for a meal that includes spinach as a side dish, then use the calculator below to work out how much you’ll need for your party size (in both metric and imperial weights).

This calculator is based on uncooked weights in both imperial and metric. If you are going to be cooking or steaming your spinach I would recommend selecting the large portion option due to shrinkage (see below for more information on shrinkage).

How Much Does Spinach Shrink When Cooked?

When spinach is steamed (without water) it releases water and shrinks in size and weight. To find out how much spinach shrinks during cooking, I did some testing by steaming different portion sizes to get an average amount, and I got the following result:

On average, spinach reduces in weight by 20% when it is steamed and excess liquid is drained away and this rule can be applied to any serving size.

The cooked weight of spinach = the original weight minus 20%

Using the example in the image below, I steamed 100g of spinach leaves without water and then drained away the liquid which came out of the spinach during cooking and the cooked weight was 80g.

How Much Does a Cup of Spinach Weigh?

Uncooked and cooked spinach weights are very different, so I weighed cups of both to get accurate information.

The average weight of one US cup of uncooked spinach is 30g/1.1oz and the weight of a US cup of cooked and drained spinach is 200g (7.05oz).

How Much Does a Handful of Spinach Weigh?

Some advice states that a serving of uncooked spinach is a handful, but it’s not clear how much a handful is in terms of weight, so I did the research to find out.

An average handful of uncooked spinach weighs 20g (0.7oz) and contains 5 calories (in kcal).
