# Get Array Size – NumPy

## NumPy – Array size

In NumPy, array size is defined as the total number of elements in the array.

To get the size of a numpy array, we can read the size property of the array object.

For example, if arr is the numpy array, then arr.size returns the size of the array.

## Examples

### 1. Get size of an array with shape (3, 5)

In the following program, we take a numpy array of shape (3, 5), and get its size programmatically using size property.

Python Program

``````import numpy as np

arr = np.ones((3, 5))
size = arr.size
print(size)``````
Run Code Copy

Output

``15``

### 2. Get size of an array with shape (3, 5, 16)

In the following program, we take a numpy array of shape (3, 5, 16), and get its size programmatically using size property.

Python Program

``````import numpy as np

arr = np.ones((3, 5, 16))
size = arr.size
print(size)``````
Run Code Copy

Output

``240``

## Summary

In this NumPy Tutorial, we learned how to get the size of a numpy array in Python using size property of array object.
