Tkinter widgets are supposed to be present in the Tkinter application window. All the widgets can be configured and customized by using predefined properties or functions.
To get the width of a widget in a Tkinter application, we can use winfo_width() method. It returns the width of the widget which can be printed later as the output.
Example
#Import the required libraries
from tkinter import *
#Create an instance of Tkinter Frame
win = Tk()
#Set the geometry
win.geometry("700x350")
#Set the default color of the window
win.config(bg='#aad5df')
#Create a Label to display the text
label=Label(win, text= "Hello World!",font= ('Helvetica 18 bold'), background= 'white', foreground='purple1')
label.pack(pady = 50)
win.update()
#Return and print the width of label widget
width = label.winfo_width()
print("The width of the label is:", width, "pixels")
win.mainloop()Output
Running the above code will display a window that contains a Label widget.
When we compile the code, it will print the width of the label widget on the console.
The width of the label is: 148 pixels
