Text Keeps Disappearing When I Change Font SIze

@sui347 , the text tool in Photoshop does take some getting used to. Here is an article that covers lots of details. I'll give you my meager tips, in case it helps.

There are two text 'modes' available that are distinct; "point" text and "paragraph" text (ignoring text on a path).

1. Point Text: if you click the T tool (text tool) and click onto the canvas, then start typing, the text takes on the characteristics of 'point text'. It will keep going on and on beyond the edge of the canvas unless you insert a paragraph return. There is no text box limitation to 'point' text, as it will not clip within the bounds of any rectangle, like paragraph text does (see below). So point text should not disappear, like what you described above.

2. Paragraph text: with the Text tool, drag a rectangle on the canvas before you start typing (as opposed to just clicking once on the canvas); now the text you type will be forced to fit within the text rectangle that you drew, including hyphenation and line endings. And you can resize two different ways: Double click on the text and you can change the dimensions of the paragraph box, but the type stays the same size; you only scale the box, not the text. Alternatively, you can use the Transform command to scale the text so that it resizes along with the size of the paragraph text box; this will make the text larger or smaller, depending on if you make the paragraph text larger or smaller.

Experiment with these two text modes and decide whether Point text might be the right editing mode for you; I believe with that mode, you shouldn't have disappearing text, but with Paragraph text + the double click approach, the text will scale along with the text box itself, which I think also could be what you want.

Hope those tips help!
