line_height = 1.0

Scales the computed line height to adjust the spacing between successive rows of text. The default line height is controlled by the font_size configuration option. If you feel that your chosen font feels too vertically cramped then you can set line_height = 1.2 to increase the vertical spacing by 20%. Conversely, setting line_height = 0.9 will decrease the vertical spacing by 10%.
