# Measure distance in a PDF on iOS

Measure distance in a PDF using Nutrient iOS SDK starting with version 11.5. To measure distance 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 distance in one of the following ways:

- [Measure the distance between two points](#measuring-distance-between-two-points)

- [Measure the distance between multiple connected points](#measuring-distance-between-multiple-connected-points)

## Measuring distance between two points

Measure the distance between two points in one of the following ways:

- [Using the built-in user interface (UI)](#measuring-distance-between-two-points-using-the-built-in-ui)

- [Programmatically](#measuring-distance-between-two-points-programmatically)

### Measuring distance between two points using the built-in UI

To measure the distance between two points using the built-in UI, follow the steps below:

1. Touch and hold the annotation tools icon.

2. Tap **Distance**.

3. Draw a straight line between the two points you want to measure.

### Measuring distance between two points programmatically

To measure distance programmatically on iOS, [contact Support](https://support.nutrient.io/hc/en-us/requests/new).

## Measuring distance between multiple connected points

Measure the distance between multiple connected points in one of the following ways:

- [Using the built-in user interface (UI)](#measuring-distance-between-multiple-connected-points-using-the-built-in-ui)

- [Programmatically](#measuring-distance-between-multiple-connected-points-programmatically)

### Measuring distance between multiple connected points using the built-in UI

To measure the distance between multiple connected points using the built-in UI, follow the steps below:

1. Touch and hold the annotation tools icon.

2. Tap **Perimeter**.

3. Draw lines between the multiple points you want to measure.

### Measuring distance between multiple connected points programmatically

To measure distance programmatically on iOS, [contact Support](https://support.nutrient.io/hc/en-us/requests/new).
