HTML Font Size Code

In HTML, font size is specified using CSS (Cascading Style Sheets). Font size is specified using the font-size property.
The actual value of the font-size property can be specified in different ways. You can specify font size in any of the following ways:
  • Absolute Size
  • Relative Size
  • Fixed Size
  • Percentage

This page includes examples of these different methods.
You can use the following HTML code to specify font size within your HTML documents. All you need to do is select your preferred option, then change the values to suit.

Option 1: Absolute Size

Absolute size refers to an entry in a table of font sizes that is calculated, and kept by the browser (or other user agent). Because of this, the text will always be displayed at the same size regardless of its surrounding elements. This is because the sizes are pre-calculated by the browser/user agent.
Copy and paste this code:


This code results in:

Absolute size - xx-small
Absolute size - x-small
Absolute size - small
Absolute size - medium
Absolute size - large
Absolute size - x-large
Absolute size - xx-large

Option 2: Relative Size

Relative size allows you to set the font size relative to the parent element. This means that different text with the same (relative) value could actually appear in many different sizes - even on the same page. It all depends on the text's parent element. There are two possible values: 'smaller' and 'larger'.
Copy and paste this code:


This code results in:
Font size specified using relative values - smaller
Font size specified using relative values - larger

Option 3: Length Value

A length value allows you to specify an absolute font size, regardless of the surrounding elements. There are eight possible values.
Relative Values:
  • em (the 'font-size' of the relevant font)
  • ex (the 'x-height' of the relevant font)
  • px (pixels, relative to the viewing device)
Absolute Values:

  • in (inches -- 1 inch is equal to 2.54 centimeters)
  • cm (centimeters)
  • mm (millimeters)
  • pt (points -- the points used by CSS2 are equal to 1/72th of an inch)
  • pc (picas -- 1 pica is equal to 12 points)

Examples of Relative Values

Option 4: Percentage Values
