Description
How to set a different font size in C# for themes which support palettes.
Solution
When using any of the Telerik themes which support palettes (the ones with the links from the list), you can dynamically change the FontSize and FontFamily properties of all components in the application.
Most controls use the theme Palette's FontSize property, yet all themes support a different number of various font sizes. For example, if the Office2016Theme is applied to your application, you can change the following font size properties of its palette:
Example 1: Modifying the FontSize and FontFamily in the Office2016 theme
Office2016Palette.Palette.FontSizeS = 10;
Office2016Palette.Palette.FontSize = 12;
Office2016Palette.Palette.FontSizeL = 14;
Office2016Palette.Palette.FontFamily = new FontFamily("Segoe UI");
Example 2: Changing the default FontSize and FontFamily in the Office2016 theme on a button click
private void OnButtonChangeFontSizeClick(object sender, RoutedEventArgs e)
{
Office2016Palette.Palette.FontSize = 14;
Office2016Palette.Palette.FontFamily = new FontFamily("Calibri");
}

The approach used in the above code snippets is applicable for the following themes - Windows8, Windows8Touch, Office2013, VisualStudio2013, Office2016, Office2016Touch, Green, Fluent, Material, Crystal and VisualStudio2019.
If you are using a different theme, which does not have a palette, you can change the font size of the application through Application.Current.MainWindow.FontSize or apply it directly for the control you wish, e.g. this.dataGrid.FontSize = 20.
