PT to Percent Converter
Convert Points (PT) to Percentage (%).
About PT to Percent Converter
The PT to Percent Converter transforms typographic points into percentage values for relative CSS layouts and responsive design. Percentage units are relative to the parent element's corresponding property, making them essential for flexible, responsive designs that adapt to container sizes. The conversion depends on the parent element's font size: if the parent is 16px (browser default), then 12pt equals 100%. This tool helps create designs that scale proportionally with their containers.
Formula
Examples
Reference
- • Point (pt): Absolute typographic unit equal to 1/72 inch
- • Percentage (%): Relative unit based on the parent element's property
- • Context-Dependent: % value changes based on parent container size
- • Font-Size: 100% = 1em = parent font sizing
Frequency Asked Questions
How do percentage units work in CSS?
Percentage units are relative to the parent element's corresponding property. For font-size, 100% equals the parent's font-size. For width, 100% equals the parent's width. The reference changes based on what property you're setting.
How do you convert PT to percent?
The conversion depends on parent font size. For a 16px parent, multiply points by 8.333. For example, 12 pt × 8.333 = 100%. For other parent sizes, use: % = (PT × 1.333333 ÷ Parent Size) × 100.
When should I use percentage units?
Use percentages for creating flexible layouts that adapt to container sizes, responsive images that scale with their parent, and typography that maintains proportional relationships. They're ideal when elements should scale relative to their container.
What's the difference between percent and EM?
Both are relative, but % can reference different properties (width, height, font-size) depending on context, while EM is always relative to font-size. For font-size specifically, 100% and 1em are equivalent.
