Line feed

Legibility is greatly affected by the amount of space between the lines – usually called “line feed” or "leading" after the strips of lead used by printers to space out l ines of metal type. If there is not enough, the space between the lines can become less that that between the words, which can confuse the eye. Generous line feed can help to carry the eye along an otherwise uncomfortably long line.

Too much space between the lines can break up continuous text unintentionally – although it can be a useful device in large headlines. However it is always better to have too much space than too little.
