PyQt5 - Create circular Push Button

Last Updated : 25 Apr, 2025

In this article we will see how to create circular push button. By default, when we create a push button it is in rectangular form although we can also change it size to square.

In order to create circular button we have to do following steps: 1. Create a push button. 2. Change its size to make it square. 3. Set radius of button to half of length or square button.

Note : If we set radius greater than the half of the length then no change will occur as that shape would not be possible.

Syntax : button.setStyleSheet("border-radius : 50;") Argument : It takes string as argument. Action performed : It sets the radius of button.

Code :

Python3

# importing libraries
from PyQt5.QtWidgets import * 
from PyQt5.QtGui import * 
from PyQt5.QtCore import * 
import sys


class Window(QMainWindow):
    def __init__(self):
        super().__init__()

        # setting title
        self.setWindowTitle("Python ")

        # setting geometry
        self.setGeometry(100, 100, 600, 400)

        # calling method
        self.UiComponents()

        # showing all the widgets
        self.show()

    # method for widgets
    def UiComponents(self):

        # creating a push button
        button = QPushButton("CLICK", self)

        # setting geometry of button
        button.setGeometry(200, 150, 100, 100)

        # setting radius and border
        button.setStyleSheet("border-radius : 50; 
                              border : 2px solid black")

        # adding action to a button
        button.clicked.connect(self.clickme)

    # action method
    def clickme(self):


        # printing pressed
        print("pressed")

# create pyqt5 app
App = QApplication(sys.argv)

# create the instance of our Window
window = Window()

# start the app
sys.exit(App.exec())
