Summary<\/strong>: in this tutorial, you will learn how Tkinter widget size works in various contexts.<\/p>\n\n\n\n

Understanding the Tkinter widget size #<\/a><\/h2>\n\n\n\n

In Tkinter, when you set the width and height for a widget e.g., a Label<\/a>, the size is measured by characters and lines, not the pixels.<\/p>\n\n\n\n

For example, the following program creates a Label<\/code> widget with a width of 8 and position it on the main window:<\/p>\n\n\n\n

\"tkinter<\/figure>\n\n\n\n

The width of the label is 8 characters. However, if you increase the font size, the width of the label widget in pixels will also increase accordingly.<\/p>\n\n\n\n

For example, the following program sets the width of the Label<\/code> widget to 8 but increases the font size to 24px. As a result, the width of the widget also increases:<\/p>\n\n\n

import<\/span> tkinter as<\/span> tk\r\n\r\nroot = tk.Tk()\r\nroot.title('Tkinter Widget Size'<\/span>)\r\nroot.geometry(\"600x400\"<\/span>)\r\n\r\nlabel1 = tk.Label(\r\n    master=root, \r\n    text=\"Sizing\"<\/span>,\r\n    bg='red'<\/span>,\r\n    fg='white'<\/span>,\r\n    width=8<\/span>, \r\n    font=('Helvetica'<\/span>,24<\/span>)\r\n)\r\n\r\nlabel1.pack()\r\n\r\nroot.mainloop()\r\n<\/code><\/span>Code language:<\/span> JavaScript<\/span> (<\/span>javascript<\/span>)<\/span><\/small><\/pre>\n\n\n
Output:<\/p>\n\n\n\n
\"tkinter<\/figure>\n\n\n\n
The size of the widget is not only determined by its properties like width and height but also controlled by the layout methods such as pack()<\/a>, grid()<\/a>, and place()<\/a>.<\/p>\n\n\n\n
For example:<\/p>\n\n\n
import tkinter as<\/span> tk\r\n\r\nroot = tk.Tk()\r\nroot.title('Tkinter Widget Size'<\/span>)\r\nroot.geometry(\"600x400\"<\/span>)\r\n\r\nlabel1 = tk.Label(master=root, text=\"Sizing\"<\/span>,bg='red'<\/span>, fg='white'<\/span>, width=20<\/span>)\r\nlabel1.pack(\r\n    # Remove the fill and run the program to see the effect<\/span>\r\n    fill=tk.X \r\n) \r\n\r\nroot.mainloop()\r\n<\/code><\/span>Code language:<\/span> PHP<\/span> (<\/span>php<\/span>)<\/span><\/small><\/pre>\n\n\n
Output:<\/p>\n\n\n\n
\"tkinter<\/figure>\n\n\n\n
The program sets the width of the Label<\/code> widget to 8 but the pack()<\/a> method uses X<\/code> as the value of the fill parameter, which instructs the widget to fill all the horizontal spaces. <\/p>\n\n\n\n
As a result, the width of the widget is always the same as the width of the container.<\/p>\n\n\n\n
Summary #<\/a><\/h2>\n\n\n\n
    \n
  • Set the size of the widget by using the width and height parameters.<\/li>\n\n\n\n
  • The layout methods such as pack(), grid(), and place() may override the size of the widget.<\/li>\n<\/ul>\n
