Use Text Best fit to fit vertically and not horizontally

Im trying to solve an issue I have with text in responsive app.

The thing is that Im creating a box containing text, which is being resized based on resolution.

I want to have text with a proper font size based on screen size so i use best fit, wrap and truncate.

The problem is that this way the text fits the whole width whatever the text is and I just want a normal text left aligned with a proper size based on the resolution.

Is there any way to make it fit the vertical all the time so the size is correct but dont try to fullfit the whole width? This way on different texts I wont have different sizes.

Thanks a lot.
