Crowding refers more to neatness in the document and enhances readability.

  1. Letters: If you are looking to fit something within a space, then you may reduce the font size or reduce the spacing between the letters. This hampers readability.
  2. Lines: Line spacing is an important aspect, no matter how big the space between words maybe but if the lines are too close to each other or too large like double spacing, it does not provide a good feel to the user.
  3. Scaling: When you type in text boxes, it is possible that the content is stretched either too horizontally or diagonally, leading to a different size than originally intended. This hampers readability
