In typography, lead ( LED -ing ) refers to the distance between lines the basis of a sequential line type. This term comes from the days of hand marking, when a thin strip of tin is put into shape to increase the vertical distance between the line types. The term is still used in modern page layout software such as QuarkXPress and Adobe InDesign.
In a consumer-oriented word processing software, this concept is commonly referred to as " line spacing " or " interline spacing ".

Origins
The word comes from a tin strip placed between the sets of lead type, the pronunciation is "ledding" and not "leeding". When the type is arranged by hand in the printing press, slug, or strip of the appropriate thickness pile is inserted between the type lines to increase the vertical space, increasing the reading.

Practice
Leads can be used to improve legibility of pages or blocks of text. The main standards used in printing are usually 2 points for body text that is mechanically arranged, or 20% in digital font settings. In both cases, the usual 10 pt font lead is 12 pt, creating a 10/12 ratio, which is considered a single space. Some types of designers recommend the leading between 120% and 145% of the font size.
Double spacing is a practice that is rooted because of the typewriter era and, in academic settings, to allow for the addition of handwritten and proofreading comments. The typewriter has a limited number of options to lead, and double spacing is selected as the default. Dual spacing increases the amount of unused free space on the page and reduces the number of lines on the page. Too much lead can cause continuity problems, because the reader's eye is required to travel further distance between the lines of the text.
The text set "solid" (without prefix) seems narrow, with ascenders almost touching the descenders from the previous line. The lack of white space between the lines makes the eye difficult to trace from one line to the next, making the river clearer, and hampering legibility.
Problem
Leading can be affected by a series of problems, all of which can be fixed or used for printer gain. Notable negative (12/10) can be viewed as an obstacle to readability. This will cause the text to be more difficult to read, because the lines will be coerced together, reducing the space between lines and inhibiting readability. However, for short text bursts, negative things can improve text messages and can make text more effective. Negative figures can be affected by ascenders and descenders in certain letters. Letters with high ascenders and low breeds can interfere with each other between lines, if leads are small enough to allow them to touch each other. Written text with several parts requiring separate sections can cause text continuity issues. Written text must have a primary standard that does not deviate from page to page. There are instances that call for change in lead, such as when block quotes are placed in written text. The lines on the front of the page and the verso (rear) should line up vertically, lines for the lines. If there are multiple instructions contained in a single page, this Convention may be entirely omitted. Fonts can also affect the need to lead. No two fonts are exactly alike, and for that reason many have characteristics that demand a particular leader. Darker fonts require a wider lead than a brighter one. In addition, serif fonts should be guided wider than the sans serif. Languages ​​can decide which leads the printer uses as well. Leading is an important issue to consider when printing, as it can improve readability, but it can also affect the number of pages, as larger prospects reduce the number of rows per page. In this way, page leads can have a profound effect on written text.
Example
This text block has the default:
typography (Greek: typos "form", graphein "to write") is an art and setting subject technique written in type using a combination of letter styles, point size, line length, lead lines, space spacing, and word spaces to produce typed artwork in physical or digital form.
The same block of text as 50% easier to read:
typography (Greek: typos "form", graphein "to write") is an art and setting subject technique written in type using a combination of letter styles, point size, line length, lead lines, space spacing, and word spaces to produce typed artwork in physical or digital form.
The same block of text at 100% is once again more readable but makes the use of vertical page space less efficient:

In the World Wide Web
In CSS, lead refers to the difference between the content height and property value line-height . Half the lead is called the leading half. The machine user centers the glyphs vertically in the inline box, which adds the leading half at the top and bottom. For example, if some of the text "12pt" is high and the high value of the line is "14pt", 2pt extra space should be added: 1pt above and 1pt below text (this applies to empty boxes as well, as if empty boxes contain zero-height text ).
Feathering
Notable can be improved to align the underline of text on the page in a process known as feathering, carding, or vertical justification.
Bastard font
In metal font settings, some fonts have a default increase or decrease. To achieve this, a smaller font face is thrown on the body of a larger font or vice versa. This kind of font is usually called a font or a "bastard" type. In notation they are usually written with faces and body sizes separated by slashes, such as 10/12 which is the face of a 10-point font on a 12-point body, or 12/10, 12-point letter face on the body of 10 points.
