Paragraph Spacing dialog

What does it mean to have a line spacing multiple at 1.15?

(My font size is 20, however when I compared 1.15 with exactly 23 point, they aren't equal.)

It means 1.15 times the single line spacing. So for example if the single line spacing was 20 point, the line spacing would be 23 point.

Effectively this gives just a little looser line spacing than the font has been designed for, making for a lighter and less formal look overall.

@Pacerier, the line spacing is not always the same as the font size. It will vary based on the font that is selected. – Mark Ransom Aug 17 '11 at 4:05
@Parcerier, I just tried a slightly different test. Using the font Calibri, I compared 20pt at 1.15 spacing vs 23pt as single line spacing. They come out the same size. 20pt seems to have a default line spacing of exactly 24.4pt (22% extra) for this font. – Hand-E-Food Aug 17 '11 at 4:31

In Microsoft Word:

Line spacing options

Single This option accommodates the largest font in that line, plus a small amount of extra space. The amount of extra space varies depending on the font that is used.

1.5 lines This option is one-and-one-half times that of single line spacing.

Double This option is twice that of single line spacing.

At least This option sets the minimum line spacing that is needed to fit the largest font or graphic on the line.

Exactly This option sets fixed line spacing, expressed in points. For example, if the text is in a 10-point font, you can specify 12 points as the line spacing.

Multiple This option sets line spacing that can be expressed in numbers greater than 1. For example, setting line spacing to 1.15 will increase the space by 15 percent, and setting line spacing to 3 increases the space by 300 percent (triple spacing).

Note: Line spacing is also known as leading.
