Up above is my code and when I run the code the text is out of the window: So Is there any way I can move the text to the next line if it crosses the windows geometry.

Any suggestions will help thank you.

You can use the text_size attribute, like this:

self.add_widget(Label(text_size=(500, None), text="Super long textSuper ...

Another way is to use kivy language to set up bindings that adjust the text_size as the window size changes:

from kivy.app import App
from kivy.lang import Builder
from kivy.uix.label import Label
from kivy.uix.gridlayout import GridLayout

kv = '''
<MyLabel>:
    size_hint: 0.5, 0.5
    text_size: self.size
'''

class MyLabel(Label):
    pass


class MyGrid(GridLayout):
    def __init__(self, **kwargs):# handle as many can com in **kwargs
        super(MyGrid, self).__init__(**kwargs)
        self.cols = 1
        self.add_widget(MyLabel(text="Super long textSuper long textSuper long textSuper long textSuper long textSuper long textSuper long textSuper textSuper textSuper textSuper textSuper textSuper textSuper textSuper textSuper textSuper textSuper textSuper textSuper textSuper textSuper textSuper textSuper textSuper textSuper textSuper textSuper textSuper textSuper textSuper textSuper textSuper textSuper textSuper textSuper textSuper textSuper textSuper textSuper textSuper textSuper textSuper textSuper textSuper textSuper textSuper textSuper textSuper textSuper long text"))


class MyApp(App):
    def build(self):
        Builder.load_string(kv)
        return MyGrid()

if __name__ == "__main__":
    MyApp().run()

This code sets text_size to always follow the widget size in the MyLabel class. Using kv sets up a binding so that the text_size will change as the widget size changes.
