Increasing Size of Tab Button in Tkinter Notebook

How can you increase the size of the button used to access the tab?

I've tried adding padding, changing the font size, and editing height/width, but none of these affect the physical size of the button used to switch tabs.

Change the style like:

customed_style = ttk.Style()
customed_style.configure('Custom.TNotebook.Tab', padding=[12, 12], font=('Helvetica', 10))

Then use this style to your tab like:

tab_control = ttk.Notebook(self.master, style='Custom.TNotebook')

Here is a full example:

import tkinter as tk
from tkinter import ttk

class MainWindow:
    def __init__(self, master):
        self.master = master
        self.master.title("Large Tab Example")

        self.createTabs()

    def createTabs(self):
        self.tab_control = ttk.Notebook(self.master, style='Custom.TNotebook')

        self.tab_one = ttk.Frame(self.tab_control)
        self.tab_control.add(self.tab_one, text="Tab One")
        self.frame_one = ttk.Frame(self.tab_one)
        self.frame_one.grid(row=0, column=0, padx=16, pady=16, sticky='nesw')
        self.label_one = ttk.Label(self.frame_one, text="Tab One", font=('Helvetica', 24, 'bold'))
        self.label_one.grid(row=0, column=0, padx=16, pady=16, sticky='nesw')

        self.tab_two = ttk.Frame(self.tab_control)
        self.tab_control.add(self.tab_two, text="Tab Two")
        self.frame_two = ttk.Frame(self.tab_two)
        self.frame_two.grid(row=0, column=0, padx=16, pady=16, sticky='nesw')
        self.label_two = ttk.Label(self.frame_two, text="Tab Two", font=('Helvetica', 24, 'bold'))
        self.label_two.grid(row=0, column=0, padx=16, pady=16, sticky='nesw')

        self.tab_three = ttk.Frame(self.tab_control)
        self.tab_control.add(self.tab_three, text="Tab Three")
        self.frame_three = ttk.Frame(self.tab_three)
        self.frame_three.grid(row=0, column=0, padx=16, pady=16, sticky='nesw')
        self.label_three = ttk.Label(self.frame_three, text="Tab Three", font=('Helvetica', 24, 'bold'))
        self.label_three.grid(row=0, column=0, padx=16, pady=16, sticky='nesw')

        self.tab_control.grid(row=0, column=0, sticky='nesw', padx=4, pady=4)

def main():
    root = tk.Tk()

    customed_style = ttk.Style()
    customed_style.configure('Custom.TNotebook.Tab', padding=[12, 12], font=('Helvetica', 10))
    customed_style.configure('Custom.TNotebook', tabposition='wn')

    app = MainWindow(root)
    root.mainloop()

if __name__ == '__main__':
    main()
