Python Turtle Size - Detailed Guide - Python Guides (2024)

In this Python Turtle tutorial, we will learn How to control turtle size in Python Turtle and we will also cover different examples related to Turtle size. And, we will cover these topics.

• Python turtle size
• Python turtle size in pixel
• Python turtle screen size
• Python turtle pen size

Python turtle size

In this section, we will learn about how to control or change turtle size in Python turtle.

The default size of the turtle is 20 Pixels we can also change the size of the turtle according to our requirement. If we want a large turtle then, we increase the size of the turtle. If we want a small turtle then, we decrease the turtle size.

Code:

In the following code, we will import the turtle module from turtle import *, import turtle.

• We will create a screen object by using ws=turtle.screen().
• turtle.setup(500,500) is used to set the size and position of the main window.
• ws.title(“Python Guides”) is used to set the title of the window.
• ws.bgcolor(“black”) is used to give the “black” background-color.
• incr = tuple([2 * num for num in size]) is used to increase the size of turtle.

from turtle import *import turtleturtle.setup(500,500)ws = turtle.Screen()ws.title("Python Guides")ws.bgcolor("black")tur = turtle.Turtle()tur.shape("turtle")tur.color("cyan")tur.left(90)def increaseSize(): size = tur.turtlesize() incr = tuple([2 * num for num in size]) tur.turtlesize(incr) #this is where the error occursws.onkey(increaseSize, "x")ws.listen()turtle.done()

Output:

After running the above code, we get the following output in which we can see the Turtle is placed on the screen with its new size.

Python turtle size in pixel

In this section, we will learn about turtle pixel size in python turtles.

Before moving forward, we should have a piece of knowledge about Pixel. A pixel is a unit of a digital image or we can say that a small dot or square builds up an image on the screen and also resize the image pixel size.

Code:

In the following code, we will import the turtle module from turtle import *, import turtle.

• We will create a screen object by using wn= turtle.Screen().
• tur.speed(0) is used to give the speed to the turtle and 0 is the fastest speed.
• tur.forward(20) is used to move the turtle in the forwarding direction.
• tur.begin_fill() is used before drawing the shape to be filled.
• tur.end_fill() is used for the ending of filling of the color.

from turtle import *import turtlewn=turtle.Screen()wn.bgcolor("Black")tur=turtle.Turtle()tur.speed(0)tur.pensize(4)def square(): for i in range(4): tur.forward(20) tur.right(90)def square_box(): for i in range(4): tur.begin_fill() square() tur.color("red") tur.end_fill() tur.color("Black") tur.forward(20) square_box()tur.penup()tur.forward(100)tur.pendown()turtle.done()

Output:

After running the above code, we get the following output in which we can see the turtle size in pixel. We can also resize the size of the pixel by simply increasing or decreasing the size.

Python turtle screen size

In this section, we will learn about how to customize the screen size in python turtle.

Screen size is used to resize the canvas where we draw pictures, images, shapes, etc. Screen size is used to resize the width and height of the window.

Code:

In the following code, we import a turtle module in python where we use a screensize() function which helps to resize the screen size by giving width and height to the window.

from turtle import *import turtle turtle.screensize(canvwidth=400, canvheight=300, bg="cyan")turtle.done()

Output:

After running the above code, we get the following output in which we see the screen with the given height and width.

Python turtle pen size

In this section, we will learn about how to change the pen size in python turtle.

Pen size is used to set the thickness of the line. The pen is used for drawing the shapes on the screen we can set the pen size as how thick or thin the shape is drawn or the text is written.

Code:

In the following code, we will import the turtle module for drawing the shape on the screen with the help of a pen.

• tur.color(‘cyan’) is used to give the color to the text.
• tur.pensize(14) is used to give the size to the pen to increase or decrease the thickness of the text,shape.

from turtle import *import turtle as turtur.color('cyan')tur.title("Python Guides")tur.pensize(14)style = ('Courier',25, 'bold')tur.write('PythonGuides', font=style, align='center')tur.done()

Output:

After running the above code we get the following output in which we can see the text is written on the screen with the help of a pen.

Python turtle font size

In this section, we will learn how to set the font size in Python turtle.

Font size is defined to give a size to our font that depends upon a document if it is a heading giving a large font size and writing inside the paragraph we give a small size to our text.

Code:

In the following code, we will import the turtle module. The turtle() method in python is used to make objects.

• tur.color(‘cyan’) is used to give the color to text.
• tur.write() is used to write the text on the screen.
• font=(“Times New Roman”,28,”bold”) is used to give font to text.

from turtle import *import turtle as turtur.color('cyan')tur.title("Python Guides")tur.pensize(14)tur.write('Hello Guides', font=("Times New Roman",28,"bold"), align='center')tur.done()

Output:

After running the above code we get the following output in which we can see the text is written on the screen with a suitable font size.

Python turtle image size

In this section, we will learn about the image size in Python turtle.

The size of the image is automatically adjusted according to the size of the window.

Code:

In the following code, we import the turtle module that is used to make objects.

turtle.addshape(“Python turtle image size.gif”) is used to add images accordingly to the shape of the window.

tur.resizemode(“auto”) is used to automatically resize the image .

import turtleturtle.addshape("Python turtle image size.gif")tur = turtle.Turtle()tur.shape("Python turtle image size.gif")tur.resizemode("auto")tur.pensize(15)tur.stamp()turtle.exitonclick()

Output:

After running the above code we get the following output in which we can see the image is adjusted automatically on the screen.

Python turtle dot size

In this section, we will learn about how to set the dot size in Python turtle.

Dot is created with the help of tur.dot() function we can resize this dot simply by increasing or decreasing the value put in the argument.

Code:

In the following code, we import the turtle module from turtle import *, import turtle as tur. This turtle() method is used to make objects.

• tur.forward(100) is used to move the turtle in the forwarding direction.
• tur.dot(40, “cyan”) is used to draw a dot after moving forward direction.

from turtle import *import turtle as tur # motiontur.forward(100) # dot with# 60 diameter# yellow colortur.dot(40, "cyan")tur.done()

Output:

After running the above code we get the following output in which we can see an arrow with a colored dot is placed on the screen.
