Is there a way to get one?

Here is how I can adjust checkbox size: QML: Resize CheckBox

To calculate the height of the font you must use FontMetrics:

CheckBox {
    text: "CheckBox"
    anchors.centerIn: parent
    checked: true

    indicator.width: indicator.height
    indicator.height: fontMetrics.height

    FontMetrics {
        id: fontMetrics
    }
}
