Bootstrap's global default font-size is 14px, with a line-height of 1.428. This is applied to the <body> and all paragraphs. In addition, all <p> elements have a bottom margin that equals half their computed line-height (10px by default).
Bootstrap uses Helvetica Neue, Helvetica, Arial, and sans-serif as default font.
All HTML headings (h1 to h6) are styled in Bootstrap.
