Style Your Text
Plain words are fine, but real apps need emphasis. Text accepts simple arguments to control size, weight, and style without any XML.
Set the Size
Use fontSize to make text bigger or smaller. Sizes use the sp unit, which respects the user accessibility font settings.
Text("Big title", fontSize = 24.sp)Why sp, Not dp
Text uses sp so it scales with the system font size. Layout uses dp, but words should grow when a user prefers larger text.
Make It Bold
Reach for fontWeight when you want emphasis. FontWeight.Bold is the everyday choice for titles and important labels.
Text("Headline", fontWeight = FontWeight.Bold)Weights Are a Scale
Weight is more than bold or not. FontWeight ranges from Light to Black, so you can dial in exactly the emphasis a design asks for.
FontWeight.Light
FontWeight.Medium
FontWeight.BlackAdd Italics
Slant your text with fontStyle. FontStyle.Italic is great for quotes, captions, or a subtle hint of personality.
Text("a note", fontStyle = FontStyle.Italic)Mix Them Together
These arguments combine freely. One Text call can be large, bold, and italic at once, all in a single readable line of code. 🙂
Text("Wow", fontSize = 20.sp,
fontWeight = FontWeight.Bold)Change the Font Family
Swap the typeface with fontFamily. Built-ins like Serif and Monospace ship for free, and you can load custom fonts too.
Text("code", fontFamily = FontFamily.Monospace)Letter Spacing
For airy, polished headings, nudge letterSpacing. A little extra space between characters can make uppercase titles feel premium.
Text("MENU", letterSpacing = 2.sp)Lean on Theme Styles
Instead of setting each value, pass a ready-made style from MaterialTheme. It keeps every screen visually consistent.
Text("Title", style = MaterialTheme.typography.titleLarge)Small Touches, Big Polish
Size, weight, and style are tiny arguments, but together they turn flat text into a clear hierarchy users instantly understand.
