+## Description
+
+This knowledge base article shows how to resolve font differences between server-side and client-side PDF generation.
+
+## Solution
+
+Usually, the main difference between the server and client-side generated PDF documents is the font. To achieve consistent font formatting between the client-side and server-side PDFs, follow these steps:
+
+1. Install the [Telerik.Documents.Fixed]({%slug available-nuget-packages%}) NuGet package.
+2. Specify the font explicitly for text elements in the server-side PDF generation code.
+3. Load the required font file and register it with the `FontsRepository`.
+
+Use one of the following options to set the font for text blocks:
+
+### Option 1: Explicitly Set Font for Blocks
+Register and apply the font as shown in the example below:
+
+```csharp
+byte[] fontData = File.ReadAllBytes(@"C:\Windows\Fonts\calibri.ttf");
+FontFamily fontFamily = new FontFamily("Calibri");
+FontsRepository.RegisterFont(fontFamily, FontStyles.Normal, FontWeights.Normal, fontData);
+
+FontBase calibriFont;
+bool success = FontsRepository.TryCreateFont(fontFamily, FontStyles.Normal, FontWeights.Normal, out calibriFont);
+
+var c0 = row.Cells.AddTableCell();
+c0.PreferredWidth = preferredWidths[0];
+Block block1 = c0.Blocks.AddBlock();
+block1.TextProperties.Font = calibriFont;
+block1.InsertText(reportItem.JobNumber ?? string.Empty);
+```
+
+### Option 2: Use FontFamily for Text Insertion
+Alternatively, utilize the `FontFamily` directly during text insertion:
+
+```csharp
+byte[] fontData = File.ReadAllBytes(@"C:\Windows\Fonts\calibri.ttf");
+FontFamily fontFamily = new FontFamily("Calibri");
+FontsRepository.RegisterFont(fontFamily, FontStyles.Normal, FontWeights.Normal, fontData);
+
+var c10 = row.Cells.AddTableCell();
+c10.PreferredWidth = preferredWidths[10];
+c10.Blocks.AddBlock().InsertText(fontFamily, reportItem.StatusDate?.ToString("dd/MM/yyyy") ?? string.Empty);
+```
+
+Ensure consistent usage of fonts between client-side and server-side export processes. Use the same font family and size as implemented in the client-side export.
