Why rem divides by 16
Because browsers default the root font size to 16 px, and rem is a multiple of it. When a reader enlarges text in their browser settings, only the parts written in rem grow — anything pinned in px stays put.
Nearby sizes
On screen, pt and inches are still pixels
CSS fixes one inch at 96 px and one point at 1/72 inch. So 16 px is exactly 12 pt — but hold a ruler to the screen and that "inch" will not measure an inch.

Body text at 16, small text at 14, spacing at 8, 24 and 32 — the values that keep coming back.
How to read this
- rem = px ÷ 16, because browsers default the root font size to 16 px.
- pt = px × 0.75, since CSS fixes an inch at 96 px and a point at 1/72 inch.
- One pc is 12 pt, and one inch is both 96 px and 72 pt.
- Use rem for text and spacing; keep px for hairlines such as borders.
