Condensed fonts have narrower letterforms than usual. Condensed fonts are useful, as they allow more text in a smaller area.
There are two ways to get condensed type: either by using a typeface designed as a condensed style, or by starting with a regular font and squishing it with your word processor using the character formatting options.

squished font

Can you see the difference? The squished font (on the bottom) only gets reduced in the horizontal direction, so the vertical strokes of the letters get thinner, but the horizontal strokes don’t. The result is a typeface that’s out of proportion.
Avoid squishing type (or stretching it to get expanded type). If you need a condensed or expanded typeface, get one that was designed for the purpose.
There are actually three ways: using a narrower typeface, reducing the width of each character, or adjusting the spacing between letters so that characters are placed closer together (but not squishing the letters themselves). I know that Word’s settings allow you to distinguish between the latter two.
Да все верно!))
One exception I’d argue for: you may need to squish small passages to avoid very ugly URL reformatting problems. Just squishing a few dozen characters by 0.1 point can be unnoticable even by the trained eye but can avoid major reflow problems.
