How to Convert PT to Percentage

 

 

Step 1: Determine the Parent’s Font Size

Identify the font-size of the direct parent element in pixels. The percentage value will be relative to this size. Enter it in the “Parent Font Size” field above.

Step 2: Use the Conversion Formula

The formula to convert points to a percentage is: `((PT Value * (96 / 72)) / Parent Font Size) * 100`.

Result in % = ((PT * 1.333) / Parent PX) * 100

Step 3: Example Calculation

If you want to convert 12pt to a percentage and the parent’s font size is 16px, the calculation is:

((12 * 1.333) / 16) * 100 = 100

So, 12pt is equal to 100% of a 16px parent font size.

Understanding Points (PT)

The point (pt) is a traditional unit of measurement for typography, commonly used in print design. One point is equal to 1/72 of an inch. It’s a fixed-size unit, making it reliable for print but less flexible for responsive web design.

Understanding Percentages (%)

The percentage (%) unit is a relative unit of measurement in CSS. It defines a size or length relative to the same property of its parent element. For font-size, a percentage is relative to the parent’s font-size.

Why Convert PT to Percentage?

Converting points to percentages is a key step in making print-based designs responsive on the web. This is important for:

  • Scalable Typography: Converting `pt` to `%` allows your text to scale relative to its parent container, which is essential for creating fluid and responsive layouts.
  • Maintaining Proportions: It helps to preserve the typographic hierarchy and proportions of a print design when it is adapted for different screen sizes.
  • Modern Web Development: Using relative units like percentages is a fundamental practice in modern web development for creating flexible and maintainable websites.
