How many points equal 1 em?

12 points = 1 em (at 12pt default font size). So conversely, 1 pt ≈ 0.0833 em. This assumes print standard sizing.

My print spec says 18pt font. What em value should I use in CSS?

18 pt ÷ 12 = 1.5 em. Use font-size: 1.5em in CSS for responsive sizing that maintains the print hierarchy.

Does the conversion change if my em base isn't 12pt?

Yes. If your design uses 16pt web base, then 1 em = 16pt, not 12pt. Divide points by your actual em base: 18 pt ÷ 16 = 1.125 em at web base.

Why use em instead of just converting points to pixels?

Em units scale with font size changes and are device-independent. Pixels don't scale. Using em makes designs responsive and accessible.

Points are absolute typographic units; ems are relative units (1 em = font size, typically 12pt in print). At the print default (12pt), 1 point equals approximately 0.0833 ems. This conversion is crucial when translating print font specifications to CSS-based responsive web design where relative sizing is essential.
