Hi Luca, Go to the layer properties and define the Labels as you would do if you don't need this kind of difference in size. Next define a constant size just defining if using a pixel size or layer units. Just beside the size number there is a button, just click on it and select the "edit" option. In the text canvas that will open use something like:
====================8<--------- clip here ---------------- case when "cityimportance" >1200 then 3500 when "cityimportance" < 1200 AND "cityimportance" > 500 then 1000 when "cityimportance" < 200 AND "cityimportance" > 100 then 500 else 250 end ====================8<--------- clip here ---------------- Of course the "cityimportance" should be some layer attribute and the example above should provide the test for some ranges. The number after the "then" or "else" clauses are the sizes, in the example it is meant to be the area of some polygon layer I had in a map. Just adapt accordingly. Naturally you can use the same approach for any other characteristic that shows that kind of button beside it.
