I am trying to recreate the symbology from the map below. As you can see, each class has a single size and a single color. All values from 0-20 have the same size and the same blue color and so on.
enter image description here

When I try to recreate that symbology, with my values, I just can't adjust the size across a class. To get my result, I used Graduated symbology, then went to Symbol, dropdown arrow, Configure symbol, and then on Size, switched to Map Units, and on the Field Type, I have chosen the same variable as for color, and I get the below result.

What I need is that everything that is red, to have the same size; the same goes for the other colors.

I am using QGIS 3.26.2-Buenos Aires.

  • Are you asking how to create categorized symbols?

  • sort of, a categorized symbology will show all the available values, and my data is continuous and not suited for a categorized symbology; you could say I would need categorized symbols with continuous data.

  • Fair enough, forgot about that. Still, using 3.22 and mockup data graduated symbols behave just as you want them to. Maybe you activated data driven symbol size?

  • @Kasper, you are correct, it was just another case of overthinking GIS from my side. Please add this as an answer.

Don't set the size from the same variable as for color, otherwise each individual symbol will have a given specific size (ranging from 67 to 506 for your red bin).

Just click on each category symbol, and set its size manually as you need
