Set the line height to a minimum to prevent any text from being cropped

Question

Set the line height to a minimum to prevent any text from being cropped

Is there a recommended line height standard to prevent text from being cropped at the top or bottom regardless of font style, weight, and size?

One might initially consider using 100% or 1, but setting line-height: 100% or line-height: 1 can result in letters like g and y being partially cut off depending on the font. Based on my experience, line-height: 1.2 seems to be the minimum required.

Is there a specific (possibly relative) value for line-height that guarantees no part of a character will be clipped?

If you want to set the line height to a default value, you can simply use line-height: normal:

normal

This tells browsers to determine an appropriate line height based on the font of the element.

By using this property, you're allowing the browser to calculate the optimal line spacing taking into account various factors like the font's style, family, and weight. Here is an example:

$(function() {
  $("p").each(function() {
    var h = $(this).height();
    $("<span style='background: #FC0;'></span>").text(" (" + h + "px)").appendTo(this);
  });
});

p {
  font-size: 16px;
  line-height: normal;
}
.font-1 p {
  font-family: sans-serif;
}
.font-2 p {
  font-family: monospace;
}
.font-3 p {
  font-family: "Open Sans";
