The Math Behind pt ↔ px Conversion
A point (pt) has been standardized since the DTP revolution (PostScript) as exactly 1/72 of an international inch (approx 0.3528 mm).
A standard CSS pixel (px) is defined by the W3C as 1/96 of an inch on a standard viewing angle display.
Why is 12pt the universal default?
12 points equals 1/6th of an inch (1 pica in typography). On a 96 DPI monitor, 12 × 1.3333 = 16px. That is why both Microsoft Word (12pt default) and modern Web Browsers (16px default) display virtually identical physical text sizes on consumer laptops!
Frequently Asked Questions (FAQ)
How do you convert pt to px?
At standard screen resolution (96 DPI in CSS and modern browsers), 1 point (pt) = 1.3333 pixels (px). Formula: px = pt × 1.3333. For example: 12pt × 1.3333 = 16px. 9pt × 1.3333 = 12px.
What is 12pt in px?
12pt is exactly 16px at 96 DPI screen resolution (12 × 96 / 72 = 16). This is why 12pt in Microsoft Word / Google Docs corresponds directly to the default 16px body font size on the web.
Why is 1pt equal to 1.333px in CSS?
A point is a physical unit defined as 1/72 of an inch. Standard screen displays are calculated at 96 CSS pixels per inch (DPI). The ratio is 96 ÷ 72 = 4/3 ≈ 1.33333. Therefore, 1pt = 4/3 px.
What is the difference between pt and px for web vs print?
Points (pt) are physical print units designed for fixed-size mediums like paper books, PDFs, and legal contracts. Pixels (px) and rem are relative digital screen units designed for varying screen resolutions and responsive viewports.
