If your VM is still running and you don't see the size you want in the list, stopping the virtual machine may reveal more sizes.
When you attempt to resize an Azure VM's size while it is running, the portal or CLI sometimes shows only a limited set of compatible VM sizes. This is because the VM is bound to a particular hardware cluster, and only certain sizes are supported in that cluster. By deallocating (stopping and releasing the compute host) the VM first, you allow Azure to reassign it to a cluster that supports more size options. After deallocation, you often see additional VM sizes available for resizing.

> [!WARNING]
> Deallocating the VM also releases any dynamic IP addresses assigned to the VM. The OS and data disks are not affected.
