# kernelBitness

## kernelBitness

The kernelBitness describes the number of bits your kernel is running. 

If you need to know what bitness your app is running as use [userSpaceBitness](/reference/sysinfo/userspacebitness.md).

{% hint style="info" %}
In most cases you actually want to use userSpaceBitness as it more correctly reflects the capabilities that your application has access to. The usersSpaceBitness constrains how much memory you can allocate.
{% endhint %}

Possible values are:

* 32
* 64

#### Example:

```dart
import "package:system_info2/system_info2.dart";

print("Kernel bitness          : ${SysInfo.kernelBitness}");
```
