# Flutter Typography Measurement

## Overview
Understanding how to measure typography in Flutter is crucial for designing user-friendly interfaces. Typography not only affects the readability of your application but also its overall appeal.

## Key Measurements
- **Font Size**: The default font size can be adjusted in your app's theme. Use the `fontSize` property to specify the size.
- **Line Height**: This is a vertical space between lines of text. Adjust using the `height` property.
- **Letter Spacing**: Control the space between letters using `letterSpacing` property.

## Example
Here is an example of Flutter code for setting typography:

```dart
Text(
  'Hello, Flutter!',
  style: TextStyle(
    fontSize: 24,
    height: 1.5,
    letterSpacing: 2.0,
  ),
)
```

## Tips
- Always consider the context of use for font sizes and styles.
- Test typography across different device sizes to ensure legibility.
