Frequently Asked Questions

20.25rem equals 324px at a 16px root font size (20.25 × 16 = 324).
Yes. If the root font size is 18px, 324px equals 18rem, and at 20px it equals 16.2rem. The pixel value itself never changes, only the rem equivalent. Use the base font size field above to try any value.
Prefer rem for font sizes, spacing and layout so they respect the user's browser font settings and scale for accessibility. Use px for details that should never scale, such as 1px borders or fixed icon sizes.
