Reply To: Same space between words

What’s weird is that when I apply those settings from David Blatner (https://creativepro.com/adjust-word-spacing-in-paragraph-styles.php), it works fine but it takes a lot of place. As soon as I reduce the letter spacing (to save space), the word spacing is not more homogeneous.

Anyway I use David Blatner’s settings on pages where I have a lot of space
and other setting (letter spacing -10 -5 -2) where i have less space.

Thanks for your help !
