Safari font rendering issues

Safari has an issue with fonts. The easiest fix for the duplicate text issue is clarifying the font-weight:

font-weight: 400;

Using Lucho's Javascript's text stroke solution along with specifying font-weight will make your text the same as it is on Chrome.


There is a CSS property, text-rendering, which in Safari is by default set to optimizeSpeed. What you want to change is:

text-rendering:optimizeLegibility;

From https://css-tricks.com/almanac/properties/t/text-rendering/

There are four possible values:

• auto (default) - The browser makes educated guesses about when to optimize for speed, legibility, and geometric precision while drawing text. Be aware that different browsers interpret this value differently.

• optimizeSpeed - The browser emphasizes rendering speed over legibility and geometric precision when drawing text. It disables kerning and ligatures.

• optimizeLegibility - The browser emphasizes legibility over rendering speed and geometric precision. This enables the use of special kerning and optional ligature information that may be contained in the font file for certain fonts.

• geometricPrecision - The browser emphasizes geometric precision over rendering speed and legibility. Certain aspects of fonts—such as kerning—don't scale linearly, so geometricPrecision can make text using those fonts look good. When SVG font is scaled, the browser calculates pixel size, then rounds to the nearest integer. The geometricPrecision property allows for more fluid scaling. Note: Only WebKit browsers apply this fluid value, Gecko treats the value just like optimizeLegibility.

There is an additional setting -webkit-font-feature-settings, of which one of them is kerning:

-webkit-font-feature-settings

h2 {
     -webkit-font-feature-settings: "kern" 1;
}

If, as per your comment, you are only serving .otf, you will need to serve the other file types too.

This could be causing an issue to do with iOs as until iOs 4.2, SVG was the only format to use custom fonts on the ipad or iphone.

@font-face {
  font-family: 'MyWebFont';
  src: url('webfont.eot'); /* IE9 Compat Modes */
  src: url('webfont.eot?#iefix') format('embedded-opentype'), /* IE6-IE8 */
       url('webfont.woff2') format('woff2'), /* Super Modern Browsers */
       url('webfont.woff') format('woff'), /* Pretty Modern Browsers */
       url('webfont.ttf')  format('truetype'), /* Safari, Android, iOS */
       url('webfont.svg#svgFontName') format('svg'); /* Legacy iOS */
}

A great tool to use is Font Squirrel's Webfont Generator

Edit: Also as mentioned in the comments the font-weight is set to bold by default and you are loading a light font.
