In this article, I’ve put together easy-to-follow charts and a calculator so you can quickly work out weights and calories of various portions of broccoli, including weights per person for meal planning.
Broccoli Types and Weights
There are three main types of broccoli that you can buy in stores and supermarkets, these are whole broccoli heads, broccoli florets, and Tenderstem (as it’s known in the UK) or Broccolini (as it’s known in the USA).
I’ve done the research and weighed a large amount of different types of broccoli to work out average weights. The chart below shows the average weights of broccoli in grams and ounces:
| Broccoli type | Average Weight |
| Broccoli Head | 300-400g/10.6-14oz |
| Broccoli Floret | 20g/0.7oz per floret |
| Tenderstem Broccoli/Broccolini | 16g/0.6oz per stem |
Because broccoli is a natural product, its worth noting that weights will vary and will also depend on the length of the stalk.
Broccoli Weight and Calorie Calculator
Use the calculator to work out weights and calories for your portion of broccoli or Tenderstem broccoli/Broccolini.
This calculator is based on an average broccoli floret weighing 20g/0.7oz each and a Tenderstem/Broccolini Stem weighing 16g/0.56oz per stem. Both types of broccoli contain the same amount of calories at 34kcal per 100g.
Broccoli Serving Weights
If you’re meal planning and you need to know how much broccoli you’ll need for your party size, then use the chart below to work out what you’ll need to buy.
The recommended serving size of broccoli per person is one US cup which weighs around 90g/3.17oz. This is also a good amount to serve as a generous broccoli side dish.
The chart below shows a quick guide to how much broccoli you will need to feed a party from one to 10 as a side dish. This chart is based on the trimmed floret weight, with any tough stalks removed.
| Number of people | Total broccoli weight you will need |
| 1 | 90g/3.17oz |
| 2 | 180g/6.35oz |
| 3 | 270g/9.52oz |
| 4 | 360g/12.7oz |
| 5 | 450g/15.88oz |
| 6 | 540g/1.2lb |
| 7 | 630g/1.39lb |
| 8 | 720g/1.59lb |
| 9 | 810g/1.79lb |
| 10 | 900g/1.99lb |
Broccoli Stalk Waste Weight
When you buy a head of broccoli, there’s always a waste element because the tough part of the stalk needs to be removed.
I weighed the waste part of a 375g head of broccoli after removing the florets and the waste amount was 200g, which meant only 175g of the head was useable.
It’s worth knowing how much of a broccoli head is waste if you need to work out how much broccoli you need to serve a certain amount of people.
What is a Head of broccoli?
The term ‘a head of broccoli’ is used to describe the top part of the broccoli stalk which if left would turn to flowers so the plant can seed.
The flower part of the plant is the part we eat and the tough stalk part is usually removed as waste.
