What is the formula for px to pt?

pt = px × (72 / DPI). At 72 DPI (PostScript standard), 1 pt = 1 px. At 96 DPI (web standard), 1 pt ≈ 0.75 px, so 16 px = 12 pt.

Why 72 DPI for print?

The typographic point (1/72 inch) maps perfectly to 72 DPI, where 1 px = 1 pt. Most print design apps (InDesign, Illustrator) default to 72 PPI. Web browsers use 96 DPI by definition.

What DPI should I use for iOS?

iOS uses logical points independent of physical pixels. iPhone SE is 163 PPI (1×), iPhone 15 is 460 PPI (3×). For CSS-equivalent px use the logical resolution (e.g. 375pt wide for iPhone 15, not 1125 physical px).

Is pt the same in CSS and print?

In print (PostScript), 1 pt = 1/72 inch exactly. In CSS, 1pt is also defined as 1/72 inch, which at 96 DPI equals 4/3 CSS px. So 12pt in CSS = 16px at standard web DPI.

What is the difference between px, pt, and em?

px (pixel) is a screen-density unit. pt (point) is a physical unit (1/72 inch). em is a relative unit tied to the parent font size. Use px for screen, pt for print, and em for scalable layouts.

Summary

Convert px to pt (and back) at any DPI — essential when bridging screen designs with print or cross-platform typography.

How it works

Set the screen DPI — use 72 for print/PostScript, 96 for web/Windows, 163 for iPhone SE, or enter a custom value.
Enter a pixel value in the PX field to instantly see its point equivalent.
Or enter a point value in the PT field to convert back to pixels.
Use the batch tab to convert multiple values at once — paste px values separated by spaces or commas.
Read the reference table at the bottom for common type sizes across DPI presets.

Use cases

Convert a web font size (px) to the matching pt size for a print stylesheet.
Match iOS point values (1pt = 1px at 1x, 2px at 2x) to CSS pixel specs.
Verify typography scales when designing for both screen and PDF output.
Cross-check font sizes between Figma (px) and InDesign/Illustrator (pt).
Calculate correct pt values for a custom-DPI tablet or e-reader screen.
Convert Android sp/dp (treated as px at a given density) to print points.
