Convert rem to pixels and pixels to rem using your base font size. Perfect for responsive, accessible typography.
Formula: px = rem × base font size
Formula: rem = px ÷ base font size
| REM | Pixels (px) |
|---|---|
| 0.75 rem | 12 px |
| 1.00 rem | 16 px |
| 1.25 rem | 20 px |
| 1.50 rem | 24 px |
| 2.00 rem | 32 px |
Tip: using rem instead of px makes your typography more scalable and accessible. For most projects, a 16px base works well.
