I've tried to change my font size and it still has no affect. How do I actually change the font size?
<p>I'm trying to change the font size of my buttons in Tkinter so it's not so small. Does anyone have any idea on what I can do that might have the result that I'm looking for? Why is there so much text required for me to ask a question when I can ask it plainly and simply with less text?! </p>

<pre><code>from Tkinter import *
from tkFont import *


class App:
    def __init__(self):
        guiWindow = Tkinter.Tk()
        guiWindow.wm_title("FooBar")

        # Creates a custom font
        customFont = Font(size=18)

        # code to add widgets will go here
        buttonFrame = Frame()

        # colors the "ChangeLicense" button
        color = '#005DA6'

        # tells licenseChange what to do
        def openLicenseChange():
            print('Change License')

    #button properties
        licenseChange = Button(guiWindow,
                               command=openLicenseChange,
                               bd=20, bg=color, font=customFont,
                               text="Change License")

        buttonFrame.pack(side="top", fill="x")

        guiWindow.mainloop()
app=App()
</code></pre>

<p>You can create a new font and then just applying it to your widgets using <code>my_widget['font']=my_font</code>, example out of your code:</p>

<pre><code>from Tkinter import *
from tkFont import *


class App:

    def __init__(self):
        guiWindow = Tkinter.Tk()
        guiWindow.wm_title("FooBar")

        # Creates a custom font
        customFont = Font(size=18)

        # code to add widgets will go here
        buttonFrame = Frame()

        # colors the "ChangeLicense" button
        color = '#005DA6'

        # tells licenseChange what to do
        def openLicenseChange():
            print('Change License')

        # button properties
        helv36 = Font(family='Helvetica', size=36, weight='bold')
        licenseChange = Button(guiWindow,
                               command=openLicenseChange,
                               bd=20, bg=color, font=customFont,
                               text="Change License")
        licenseChange['font'] = helv36
        buttonFrame.pack(side="top", fill="x")

        guiWindow.mainloop()

app = App()
</code></pre>
