In the layout composer I want to add a title in black text with a white background.

My title will be dynamic and I want the text box ("label" in the composer) to automatically adapt its size in order to fit the text length without needing to manually change its size.

  • You simply could move the label out of the map frame?

Assuming your title text comes from a given expression (in my case I just took @layout_name)

You can set the Label's Position & Size properties X and Width to depend on your title text expression:

Set Width to be something like: A x length(title string) + B:

enter image description here

Set X to be something like: Page middle X coordinate - Width/2:

enter image description here

Here you go: enter image description here

  • thankyou, it's probably the closest solution. I guess there's no way to have a constant fit as the text length (which is expressed in number of characters I guess) is translated to millimeters or whatever measure i pick which differs from the actual length(text) measure. I notice in fact that with the same multiplier (even x1) a longer text will have a box wich exceed it in length more compared to a shorter text. Feb 10, 2023 at 9:21
  • You would need to find the appropriate A factor to have constant margins, I believe.
