Can I use my own fonts in checkout or on elements?

Due to the need for universal accessibility and the space constraints of core fields needed for making donations, it is not currently possible to change the font of elements or checkout.

A key factor of most fonts that informs this is letter width and kerning:

  • Letter weight: Not all fonts consider "medium" weight or "bold" weight the same thing, and thus are thinner or thicker. This affects letter visibility and contrast ratios, meaning that a narrower font can be less accessible than a thicker one, affecting users with a need for higher contract.
  • Letter width and kerning: Most fonts are not fixed-width, which means that the space a letter takes up horizontally and the space between letters is variable. This means that changing the font most of the time changes how much space the text takes up, even if rendered at the same "size".
