This is just for future people who also see the original question wasn't answered. Here is the answer: By default, Photoshop will set the leading to (Auto): when the text box is resized, the font is also resized using the same ratios in font size and leading. The way to keep the font size fixed to a certain point size, while allowing the text box to be resized (so that the text flow is changed, as desired, to fit in the new dimensions), is to set the leading to a fixed value. This turns off Photoshop's automatic font resizing as well. The correct fixed value for the leading is, obviously, dependent on the font type and size. From the Character panel, the setting for the leading is to the right of the font size itself: While this is counter-intuitive, it works! It's quite likely that either the defaults for Photoshop changed at some point (i.e., (Auto) became the 'new' default), or you might accidentally reset this to (Auto) without intention — this is one of those settings that persist across sessions...
