How do I give tkinter labels equal dimensions?

Question

The labels are currently side by side which is what I want. However each label's width is different. Is there a way to make each label have the same width?

Also is there a method that allows the labels to the have equal measurements and simultaneously fill all the way up to 250?

Here is my current code:

from tkinter import *

root = Tk()
root.geometry("250x50")
w = Label(root, text="Label UNO", bg="red", fg="white")
w.pack(side=LEFT)
w = Label(root, text="Label2", bg="green", fg="black")
w.pack(side=LEFT)
w = Label(root, text="Label DREI", bg="blue", fg="white")
w.pack(side=LEFT)

root.mainloop()

Answer 1

you should try checking tkinter's documentation on pack:

check if this is what you are looking for:

root = Tk()
root.geometry("250x50")
w = Label(root, text="Label UNO", bg="red", fg="white")
w.pack(side=LEFT, fill=BOTH, expand=True)
w = Label(root, text="Label2", bg="green", fg="black")
w.pack(side=LEFT, fill=BOTH, expand=True)
w = Label(root, text="Label DREI", bg="blue", fg="white")
w.pack(side=LEFT, fill=BOTH, expand=True)
root.mainloop()

Fill argument basically fills the parent container.

Expand argument will use to additional remaining space.

Also be sure to take a look at tkinter weight, here is an example.

You can use key word arguments width , and height with a tk.Label

import tkinter as tk

if __name__ == '__main__':

    root = tk.Tk()
    root.geometry("250x50")

    label_frame = tk.Frame(root)

    w = tk.Label(label_frame, text="Label UNO", bg="red", fg="white", width=8, height=2)
    w.pack(side=tk.LEFT)
    w = tk.Label(label_frame, text="Label2", bg="green", fg="black", width=8, height=2)
    w.pack(side=tk.LEFT)
    w = tk.Label(label_frame, text="Label DREI", bg="blue", fg="white", width=8, height=2)
    w.pack(side=tk.LEFT)

    label_frame.pack(expand=True)

    root.mainloop()

Notes:

• tkinter is imported as tk in order to keep the namespace tidy.

• The tk.Labels are included in a tk.Frame , so once this is built, you do not have to worry about it until you pack the frame in your GUI.

• The units for width and height are in "text units" when the label contains text.

Answer 3

To make the labels width the same , just add the width option to the label

eg width=10 this will specifies how much space, in character widths.

if you want to apply the same width to multiable labels, store the width value in a variable, lets say label_w = 10

so your code might look like this:

from tkinter import *

root = Tk()
root.geometry("250x50")
label_w = 10
w = Label(root, text="Label UNO", bg="red", fg="white", width=label_w)
w.pack(side=LEFT)
w = Label(root, text="Label2", bg="green", fg="black", width=label_w)
w.pack(side=LEFT)
w = Label(root, text="Label DREI", bg="blue", fg="white", width=label_w)
w.pack(side=LEFT)

root.mainloop()

simultaneously fill all the way up to 250

this depend on how many labels you'll create, lets say window_width = 250 and labels_all = 3 then the width option will be width = window_width/labels_all also, if you don't write a geometry values, the window size will automatically fit to labels.

if your window is simple enough , you might consider using the Packer Option expand as in expand=1 , also include the fill option if your label has color, fill Legal values: 'x', 'y', 'both', 'none'.
