To increase the line height of website text

Go to Appearance -> Editor -> style.css file
at line no 19 you will find the below css code.
Just simply change height in: line-height:22px;

body{ margin:0; padding:0; box-sizing:border-box; -ms-word-wrap:break-word; word-wrap:break-word; line-height:22px; margin:0; padding:0; color:#6e6d6d; font-size:13px; font-family:'Lato', sans-serif; }
