He spaced is the space between the various lines of a text . It is, therefore, the vertical spacing which separates the words that are written in the different lines.

The line spacing idea appears in the text processors and in the programs that allow you to create and manage content. For multiple reasons, a user may wish to modify the line spacing of their documents according to the occasion. Sometimes a small line spacing is needed, with a short distance between the lines, while in other cases a larger line spacing is required (with the lines well separated from each other).
Let's look at a specific example. In the word processor Microsoft Word 2010 , which is part of the office suite Microsoft Office 2010 , it is possible to define the line spacing of the text of a document entering the flap "Page design" and then in "Paragraph". There the user finds several line spacing options: "Simple", "1.5 lines", "Double", "Minimum", "Exact" and "Multiple".
If the person start writing with a line spacing "Simple", but then select the text and choose the line spacing alternative "Double", you will notice how the space between the lines grows. This means that the spacing "Double" offers a greater vertical separation between the lines compared to the line spacing "Simple".
In general, the line spacing measurement starts at the line of base of the line of text, understanding how "baseline" to the invisible strip on which the letters that do not have descending features rest, and reaches the baseline that registers the previous line.
While in this it was the machines of writing are part of an almost arcane existential plane, which few people remember or have known, it is important to highlight that until not many decades ago they represented the only way to pass a text to print in the home and that they also had a mechanism to modify the line spacing, even if it was not as complex and detailed as computers allow us.
He process Altering the line spacing in a typewriter is much more straightforward and simpler than in a word processor: simply adjust the value on the lever or on the corresponding rotating part, and that's it. Of course, this agility when configuring the document went hand in hand with a disadvantage to take into account: once we started using the new line spacing there was no way to "undo" our work, since each letter was printed immediately on the sheet.
It is curious to think that the immediacy of typewriters is an advantage and a disadvantage simultaneously : no need for a source of Energy Electrical, without the possibility of the operating system failing and losing our work and without having to wait for the document to be printed, we can take a typewriter and start working to get results at every step. However, before an error begins to show its disadvantages, such as to make corrections we must apply a product on the sheet, spoiling the hopes of a perfect finish.
The importance of line spacing in a text document is very large and varies according to several factors, such as the person who will read it and the type of content . Incidentally, the practice of increasing the spacing with the aim of appearing a greater extent is totally discouraged. In fact, any extreme in this value can undermine the aesthetics of the document. The balance arises when we achieve that it is readable and that its appearance is pleasant and impressive.
