How do I change the size of the radio button in Tkinter?

Asked 2 months ago, Updated 2 months ago, 3 views

I'm creating a Windows app UI in Python.The module used is Tkinter.

By default, the radio button display is very small, so I want to make it bigger, but I don't know what to do.
If anyone knows, could you give me some advice?

import tkinter ask
import ctypes

class showUI:
    
    def__init__(self):
        
        font_general=('Meiryo UI', '14', 'normal')

        try:
            ctypes.windll.shcore.SetProcessDpiAwareness (True)
        except:
            pass
        
        root=tk.Tk()
        root.title('sample')
        root.geometry ('500x100')
        
        select = tk.IntVar()
        select.set(0)
        radio0=tk.Radiobutton(
            root,
            variable=select,
            value = 0,
            text = 'Radio A',
            font=font_general
        )
        radio1 = tk.Radiobutton(
            root,
            variable=select,
            value = 1,
            text = 'Radio B',
            font=font_general
        )
        radio0.place (relx=0.1, rely=0.05)
        radio1.place(relx=0.5, rely=0.05)

        root.mainloop()
        self.select=select.get()
        root.destroy()
    
if__name__=='__main__':
    showUI()
