Impress: text overflow automatic font scaling

I would like to have fixed size text boxes in which the font automically scales as soon as the text box is ‘full’. I found several options within Libreoffice Impress, but I haven’t found what I am looking for.

So when there is a case of text overflow, pressing enter for the next line will automatically scale the font so it will fit the text box.

I know, I shouldn’t include too much text on my slides, but I cannot escape breaking that rule sometimes.

Does anyone know how to do it? I remember importing some presentation from Powerpoint left that auto font scaling characteric in tact for text boxes. I am assuming that I can set it up in Impress aswell :wink:

Select the text box, secondary click and mark Autofit Text.

Can’t find documentation (maybe it is related to the style of Master Slide).
Tested on version

Thanks for the tip. So that option is also available in Master Slide view?
