Python’s Tkinter library provides a simple yet powerful way to create graphical user interfaces. While Tkinter offers flexibility in window management, maintaining a consistent window size is crucial for a polished user experience. This article details how to create a fixed-size Tkinter window, ensuring your application’s layout remains predictable and prevents unexpected resizing issues.

Method 1: Using resizable()
The most reliable method for creating a fixed-size Tkinter window is using the resizable() method. This method directly controls the window’s resizability, preventing users from altering its dimensions. It’s straightforward and works consistently across different operating systems and window managers.
import tkinter as tk
root = tk.Tk()
root.title("Fixed Size Window")
# Prevent resizing
root.resizable(False, False)
# Add widgets here... Example:
label = tk.Label(root, text="This window cannot be resized!")
label.pack(pady=20)
root.mainloop()
This code snippet creates a window, sets its title, and then uses root.resizable(False, False) to disable resizing in both the horizontal and vertical directions. The size of the window will be determined by the widgets and their layout management (e.g., pack, grid, place).
Method 2: Specifying Geometry (Less Reliable)
Alternatively, you can attempt to control the window size using the geometry() method. This sets the initial window dimensions. However, this approach is less reliable because users might be able to override it depending on their operating system’s settings or window manager behavior.
import tkinter as tk
root = tk.Tk()
root.title("Fixed Size Window (Geometry Method)")
# Attempt to set geometry (less reliable)
root.geometry("300x200") # Width x Height
# Add widgets here... Example:
label = tk.Label(root, text="This window *attempts* to be fixed size.")
label.pack(pady=20)
root.mainloop()
This code attempts to set the window to 300 pixels wide and 200 pixels high. While it might work in some environments, it’s not a guaranteed solution for maintaining a perfectly constant size.
Choosing the Right Method
The resizable(False, False) method is strongly recommended for creating fixed-size Tkinter windows. It offers superior reliability and ensures consistent behavior across different platforms. The geometry() method can be used as a supplementary approach, but it should never be relied upon as the primary method for enforcing a fixed size.
Remember to use appropriate geometry managers (pack, grid, place) to arrange your widgets effectively within the fixed window dimensions.
