// Add three columns to the grid.
grid.Columns.Add(3);

// Set the width of each column.
for (int i = 0; i < 3; i++)
{
   grid.Columns[i].Width = page.GetClientSize().Width / 3;
}

// Set up the header cells.
PdfGridRow pdfGridHeader = grid.Headers.Add(1)[0];
pdfGridHeader.Cells[0].Value = "Employee ID";
pdfGridHeader.Cells[1].Value = "Employee Name";
pdfGridHeader.Cells[2].Value = "Details";

// Add rows to the grid.
for (int i = 1; i <= 5; i++)
{
   PdfGridRow row = grid.Rows.Add();
   row.Height = 20;
   row.Cells[0].Value = "E0" + i;
   row.Cells[1].Value = "Employee " + i;
   row.Cells[2].Value =  String.Format ("Employee {0} is a software engineer with over ten years of experience in developing scalable applications. He specializes in full-stack development and enjoys working on innovative projects.", i);
}

// Adjust the font size to fit the cell content.
AdjustFontSize(grid);

// Draw the PdfGrid on the page.
grid.Draw(page, PointF.Empty);

// Save and close the document.
using (FileStream stream = new FileStream(Path.GetFullPath(@"Output/Output.pdf"), FileMode.Create, FileAccess.ReadWrite))
{
   document.Save(stream);
}
document.Close(true);

// Method to adjust the font size to fit the cell content.
public static void AdjustFontSize(PdfGrid grid)
{
   for (int i = 0; i < grid.Rows.Count; i++)
   {
       for (int j = 0; j < grid.Columns.Count; j++)
       {
           // Get the cell.
           PdfGridCell cell = grid.Rows[i].Cells[j];

           // Get the cell font.
           PdfFont initialFont = cell.Style.Font ?? grid.Style.Font;

           // Get the cell value.
           string text = cell.Value?.ToString() ?? string.Empty;

           // Get the cell size.
           SizeF cellSize = new SizeF(grid.Columns[j].Width, grid.Rows[i].Height);

           // Get the initial font size.
           float fontSize = initialFont.Size;

           PdfFont currentFont = initialFont;

           while (fontSize > 0)
           {
               // Measure the text.
               SizeF textSize = currentFont.MeasureString(text, cellSize.Width);
               if (textSize.Height <= cellSize.Height)
               {
                   cell.Style.Font = currentFont;
                   break;
               }
               fontSize--;
               if (initialFont is PdfStandardFont)
               {
                   currentFont = new PdfStandardFont(initialFont as PdfStandardFont, fontSize);
               }
               else
               {
                   currentFont = new PdfTrueTypeFont(initialFont as PdfTrueTypeFont, fontSize);
               }
