How to Create Pixel-Perfect UI Components in Figma (Then Build Them in React)

Source: Dev.to

Quick Checklist

• Turn on Pixel Grid – View → Pixel Grid
• Use Frames (not Groups) – frames give you constraints, grids, and auto‑layout support.
• Enable Layout Grid – adopt an 8‑pt spacing system (8, 16, 24, 32…).
• Use Auto‑Layout.
• Create Styles
  • Color Styles
  • Text Styles
  • Effects (shadows)

Consistent styles → consistent code.

Inspecting Elements

Click any element and inspect:

• Width / Height
• Padding & Gap values
• Border radius
• Shadow values
• Font size / weight / line height

Copy values directly — avoid “close enough”.

Example: Figma Card → React Component

import React from "react";

export default function Card({ title, subtitle, children }) {
  const styles = {
    card: {
      width: 320,
      padding: "16px 20px",
      borderRadius: 16,
      border: "1px solid #e5e7eb",
      background: "#ffffff",
      boxShadow: "0 8px 20px rgba(0,0,0,0.04)",
    },
    title: {
      margin: "0 0 6px",
      fontSize: 18,
      fontWeight: 600,
    },
    subtitle: {
      margin: "0 0 12px",
      color: "#6b7280",
      fontSize: 14,
    },
  };

  return (
    
      
## {title}

      
{subtitle}

      {children}
    
  );
}

Usage

Match values exactly — spacing, radii, shadows, fonts. Keep components reusable (variants in Figma, props in React). Avoid “eyeballing”. Inspect → copy → paste. Pixel‑perfect happens when design and code speak the same numbers.
