The wide availability of web fonts has enabled sites to become typographical wonderlands, at the cost of increased page size and longer load times. Performance-focused developers already optimize their images and CSS; it makes sense that we should also optimize web fonts.

The good news is that doing is fairly easy: by creating your own custom font or supplying your web font hosting service with a simple variable value, you can load only the glyphs that you need for the text you have on the page, rather than the entire range of characters, numbers and symbols in the font, reducing page load times.
