+## Description
+
+Determining the precise location and size of a [TextFragment]({%slug radpdfprocessing-model-textfragment%}) in a PDF document is essential for various document processing tasks. A `TextFragment`'s position is accessible through its [Position]({%slug radpdfprocessing-concepts-position%}) property, which returns a `MatrixPosition`. This article outlines how to translate the `MatrixPosition` into (x,y) coordinates and how to calculate the width and height of a `TextFragment`.

+This KB article also answers the following questions:
+- How can I find the exact location of a text in a PDF document?
+- What is the method to determine the dimensions of a text segment within a PDF file?
+- How to use the `MatrixPosition` for locating text in a PDF document?
+
+## Solution
+
+To obtain the (x,y) coordinates and the dimensions (width and height) of a `TextFragment`, follow these steps:
+
+1. **Extract the (x,y) Coordinates:**
+
+   Each `TextFragment` has a `Position` property of type [MatrixPosition](https://docs.telerik.com/devtools/document-processing/libraries/radpdfprocessing/concepts/position#matrixposition). The `MatrixPosition` object includes a `Matrix` that exposes `OffsetX` and `OffsetY` properties. These properties represent the fragment's offset from the top-left corner of the PDF page.
+
+   ```csharp
+   float offsetX = textFragment.Position.Matrix.OffsetX;
+   float offsetY = textFragment.Position.Matrix.OffsetY;
+   ```
+
+2. **Calculate the Size (Width and Height):**
+
+   To determine the width and height of a `TextFragment`, leverage the measuring functionality of the `Block` object. First, insert the `TextFragment` into a `Block`, and then use the `Measure` method to find its size.
+
+   ```csharp
+   private static Size GetFragmentSize(TextFragment textFragment)
+   {
+       Block block = new Block();
+       block.Insert(textFragment);
+       Size textFragmentSize = block.Measure();
+       return textFragmentSize;
+   }
+   ```
+
+By following these steps, you can accurately locate a `TextFragment` within a PDF document and determine its size, enabling enhanced document processing and manipulation capabilities.
+
+## Notes
+
+- The `OffsetX` and `OffsetY` values pinpoint the location relative to the top-left corner of the PDF page.
+- The `Measure` method of the `Block` object provides the width and height of the contained `TextFragment`, facilitating precise layout and positioning operations.
