Description
This article shows how to measure text in WordsProcessing in the .NET Framework environment.
Solution
You can create a Telerik.Windows.Documents.Fixed.Model.Editing.Block instance with the same content and font properties as the Run you want to insert. Then you can call the Measure method of the block in order to obtain its measurements:
using System;
using System.Diagnostics;
using System.IO;
using System.Windows;
using System.Windows.Media;
using Telerik.Windows.Documents.Fixed.Model.Editing;
using Telerik.Windows.Documents.Flow.FormatProviders.Docx;
using Telerik.Windows.Documents.Flow.Model;
using Telerik.Windows.Documents.Flow.Model.Editing;
using Telerik.Windows.Documents.Spreadsheet.Model;
namespace ConsoleNetFramework
{
internal class Program
{
static void Main(string[] args)
{
RadFlowDocument flowDocument = new RadFlowDocument();
RadFlowDocumentEditor editor = new RadFlowDocumentEditor(flowDocument);
Section section = editor.InsertSection();
#region Verdana, font size 16
//Verdana, font size 16
FontFamily fontFamily = new FontFamily("Verdana");
string text = "This is a sample text - Verdana";
int fontSize = 16;
//FontStyles.Normal, FontWeights.Normal
Paragraph paragraph = section.Blocks.AddParagraph();
Size measurementInfo = MeasureText(text, fontFamily, fontSize, FontStyles.Normal, FontWeights.Normal);
Run run = paragraph.Inlines.AddRun(text);
run.Properties.FontFamily.LocalValue = new ThemableFontFamily(fontFamily);
run.FontStyle = FontStyles.Normal;
run.FontWeight = FontWeights.Normal;
run.FontSize = fontSize;
paragraph.Inlines.AddRun($" Width: {Math.Round(measurementInfo.Width, 2)}, Height: {Math.Round(measurementInfo.Height, 2)}");
//FontStyles.Italic, FontWeights.Normal
paragraph = section.Blocks.AddParagraph();
measurementInfo = MeasureText(text, fontFamily, fontSize, FontStyles.Italic, FontWeights.Normal);
run = paragraph.Inlines.AddRun(text);
run.Properties.FontFamily.LocalValue = new ThemableFontFamily(fontFamily);
run.FontStyle = FontStyles.Italic;
run.FontWeight = FontWeights.Normal;
run.FontSize = fontSize;
paragraph.Inlines.AddRun($" - Width: {Math.Round(measurementInfo.Width, 2)}, Height: {Math.Round(measurementInfo.Height, 2)}");
//FontStyles.Normal, FontWeights.Bold
paragraph = section.Blocks.AddParagraph();
measurementInfo = MeasureText(text, fontFamily, fontSize, FontStyles.Normal, FontWeights.Bold);
run = paragraph.Inlines.AddRun(text);
run.Properties.FontFamily.LocalValue = new ThemableFontFamily(fontFamily);
run.FontStyle = FontStyles.Normal;
run.FontWeight = FontWeights.Bold;
run.FontSize = fontSize;
paragraph.Inlines.AddRun($" - Width: {Math.Round(measurementInfo.Width, 2)}, Height: {Math.Round(measurementInfo.Height, 2)}");
//FontStyles.Italic, FontWeights.Bold
paragraph = section.Blocks.AddParagraph();
measurementInfo = MeasureText(text, fontFamily, fontSize, FontStyles.Italic, FontWeights.Bold);
run = paragraph.Inlines.AddRun(text);
run.Properties.FontFamily.LocalValue = new ThemableFontFamily(fontFamily);
run.FontStyle = FontStyles.Italic;
run.FontWeight = FontWeights.Bold;
run.FontSize = fontSize;
paragraph.Inlines.AddRun($" - Width: {Math.Round(measurementInfo.Width, 2)}, Height: {Math.Round(measurementInfo.Height, 2)}");

var psi = new ProcessStartInfo()

}
static Size MeasureText(string text, FontFamily fontFamily, double fontSize, FontStyle fontStyle, FontWeight fontWeight)
{
Block block = new Telerik.Windows.Documents.Fixed.Model.Editing.Block();
block.TextProperties.FontSize = fontSize;
block.InsertText(fontFamily, fontStyle, fontWeight, text);

}
}
Result:
