Get started today!" --- # Measure PDF area in React Native Measure area in a PDF using Nutrient React Native SDK starting with version 2.6. To measure area in your app, [contact the Sales team](https://www.nutrient.io/contact-sales) to add the Measurement Tools component to your license, or run the SDK in trial mode. Measure area in one of the following ways: - [Measure the area of a custom-drawn polygon](#measuring-the-area-of-a-polygon) - [Measure the area of an ellipse](#measuring-the-area-of-an-ellipse) - [Measure the area of a rectangle](#measuring-the-area-of-a-rectangle) ## Measuring the area of a polygon Measure the area of a custom-drawn polygon in one of the following ways: - [Using the built-in user interface (UI)](#measuring-the-area-of-a-polygon-using-the-built-in-ui) - [Programmatically](#measuring-the-area-of-a-polygon-programmatically) ### Measuring the area of a polygon using the built-in UI To measure the area of a polygon using the built-in UI, follow the steps below: 1. Touch and hold the annotation tools icon. | Android | iOS | | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | --------------------------------------------------------------------------------------------------------------------------------------------------------------------- | | | | 2. Tap **Polygon Area**. 3. Draw a polygon around the area you want to measure. | Android | iOS | | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------ | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------- | | | | ### Measuring the area of a polygon programmatically To measure area programmatically in React Native, [contact Support](https://support.nutrient.io/hc/en-us/requests/new). ## Measuring the area of an ellipse Measure the area of an ellipse in one of the following ways: - [Using the built-in user interface (UI)](#measuring-the-area-of-an-ellipse-using-the-built-in-ui) - [Programmatically](#measuring-the-area-of-an-ellipse-programmatically) ### Measuring the area of an ellipse using the built-in UI To measure the area of an ellipse using the built-in UI, follow the steps below: 1.
