## Description

This 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](https://www.telerik.com/document-processing-libraries/documentation/getting-started/installation/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, use 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);
```

Use consistent fonts between client-side and server-side export processes. Apply the same font family and size as implemented in the client-side export.
