WHY THE 4-POINT GRID SYSTEM DOMINATES UI DESIGN

Summary from the TLDR Design newsletter

The 4-point grid system is a UI design staple that balances proportional scaling, micro/macro element precision, and cross-device consistency. Its divisibility ensures harmonious layouts, avoids fractional pixels, and simplifies scaling. While alternatives like 2-point and 5-point grids offer unique benefits, the 4-point grid remains the go-to choice for versatile and consistent interfaces.
