Thonburi on iOS

Thonburi at a glance

PostScript names for every Thonburi style

iOS looks fonts up by their PostScript name, not the friendly family name. Use the names below exactly as written — they are case-sensitive.

How to use Thonburi in code

SwiftUI

Text("Hello, world")
    .font(.custom("Thonburi", size: 17, relativeTo: .body))

UIKit

let base = UIFont(name: "Thonburi", size: 17)!
label.font = UIFontMetrics(forTextStyle: .body).scaledFont(for: base)
label.adjustsFontForContentSizeCategory = true

Objective-C

label.font = [UIFont fontWithName:@"Thonburi" size:17];

CSS for Safari on iPhone and iPad

.headline {
  font-family: "Thonburi", sans-serif;
  font-weight: 700;
}

Wrapping the font in UIFontMetrics, or passing relativeTo: in SwiftUI, lets Thonburi grow and shrink with the user’s Dynamic Type setting. Read the custom fonts guide for the full checklist, or the San Francisco guide if you want Apple’s system font instead.
