1 Pt to Px – Full Calculation Guide

1 pt equals 1.3333 px.

When converting points (pt) to pixels (px), the conversion depends on the pixel density standard of 96 dpi. So, 1 pt converts to approximately 1.3333 px, because 1 pt is defined as 1/72 of an inch and pixels per inch is 96.

Conversion Formula

The formula for converting points (pt) to pixels (px) is:

px = pt × (96 / 72)

This works because one point is 1/72 of an inch, and screens typically display 96 pixels per inch (dpi). To convert points to pixels, you multiply the number of points by the ratio of pixels per inch to points per inch.

Example calculation for 1 pt:

• Start with 1 pt.
• Multiply by 96 (pixels per inch): 1 × 96 = 96.
• Divide by 72 (points per inch): 96 ÷ 72 = 1.3333 px.

Conversion Example

• Convert 5 pt to px:
  • Multiply 5 by 96 = 480.
  • Divide 480 by 72 = 6.6667 px.
• Convert 10 pt to px:
  • Multiply 10 by 96 = 960.
  • Divide 960 by 72 = 13.3333 px.
• Convert 0.5 pt to px:
  • Multiply 0.5 by 96 = 48.
  • Divide 48 by 72 = 0.6667 px.
• Convert 12 pt to px:
  • Multiply 12 by 96 = 1152.
  • Divide 1152 by 72 = 16 px.

Conversion Definitions

pt (point): A unit of length used in typography, equal to 1/72 of an inch. Points measure font sizes, spacing, and layout dimensions in print and digital typesetting. It provides a consistent scale for designers when defining text size and spacing.

px (pixel): The smallest unit of a digital image or display, representing a single point of color on a screen. Pixels vary in physical size depending on the screen’s resolution and density, affecting how images and fonts appear visually.

Conversion FAQs

Why does 1 pt equal 1.3333 px instead of 1 px?

Because points and pixels are based on different measurement systems, with points defined as 1/72 of an inch and pixels tied to screen resolution, which is 96 dpi (dots per inch) in most displays. Multiplying 1 pt by (96/72) gives 1.3333 px, reflecting this size difference.

Can the conversion between pt and px change based on device?

Yes, if the screen’s pixel density (dpi) differs from 96, the conversion rate changes. For example, high-density displays with more pixels per inch will render 1 pt as more pixels, making the size appear different unless scaling is applied.

Is the pt to px conversion always precise?

The conversion formula provides a standard approximation, but due to rounding, screen scaling, and browser rendering differences, the actual pixel size on a screen may differ slightly from the calculated value.

How do browsers handle pt and px units differently?

Browsers map pt units to px based on the 96 dpi standard, but some may round or scale values for better display. Pixels correspond directly to screen pixels, while points are scaled to pixels to maintain relative sizing across devices.

Why use pt instead of px in web design?

Points can provide consistency in printed materials or when targeting print stylesheets, while pixels give precise control over screen display. Using pt allows designers to match print sizes more closely, but px is more common for screen layouts.
