Hi Theo,
Thanks for using Syncfusion products.
You can use the type PdfTextElement to retrieve the width of the rendered string. Please find the code snippet below to do the same,
PdfDocument pdfDoc = new PdfDocument();
PdfPage page = pdfDoc.Pages.Add();
// Create a text element with text.
PdfTextElement element = new PdfTextElement("Test string", new PdfStandardFont(PdfFontFamily.TimesRoman, 2));
// Set the properties for the text element.
element.Brush = new PdfSolidBrush(System.Drawing.Color.Black);
// Draw the text element and store its layout information
PdfLayoutResult layoutResult = element.Draw(page, new PointF(5,5));
//Retrieve the rendered width of the text
float width = layoutResult.Bounds.Width;
