Difference Between 2D and 3D (With Table)

Difference Between 2D and 3D (With Table)

Everything or objects can be displayed in two forms. These two forms in which the objects or any material could be displayed are 2 2-dimensional and 3 Dimensions. These two forms of displaying or showing the objects have a few differences that people must know.

The 2D form is more of a flat form of displaying objects. In the 3D form, the objects can be displayed properly, with all the edges of the object connecting with each other to make it visible properly.

2D vs 3D                                               

The main difference between the 2D and 3D forms is that in the 2D objects, people would not find the object’s height. On the other hand, in the 3D forms, the object’s height would be present to show its structure better.

2D vs 3D

The 2D form is more used for objects, such as squares or flat objects that can be made on paper. The 2D object would be visible in a plane form in which only the front or back part of the object could be drawn. This means the person would not be able to draw or make the whole structure of the object if it is being represented in 2D form.

The 3D forms would be a good way to show the real structure of an object, as it would focus on the height of the object along with its length and breadth. For 3D objects, people should be very careful about making their edges and dimensions to clarify the object.

Comparison Table Between 2D and 3D 

Introduction                   2D objects or figures are the flat forms given to the object for displaying its properties and structure.   The 2D objects don’t have volume as they are considered plane figures.  
Involvement of z-axis      The z-axis would not be involved or required in making a 2D figure.     The 2D objects don’t have volume in them as they are considered plane figures.  
Presence of volume           The presence of the z-axis is very important for drawing or making 3D objects.The volume would be found in the 3D figures as they have a good structure with perfect edges and heights.
Presence of height         The height of the objects should not be included in making the 2D figures. The height of the objects would be displayed or required in the 3D objects as they are all about giving complete shape to the object.
Different names and examples The 3D figure is the only name given to the 3-dimensional figure. The best example of a 3-dimensional figure is the cylinder.The plane figures are also tagged as 2D figures. The best example of flat or plane figures is a circle.        

What is 2D?

In mathematics, the 2D form is one of the most important forms to learn about the shape of various objects. There are many objects whose shapes or structures require only the x and y-axis. These objects can be represented in the 2D form as they don’t require height and volume.

The 2-dimensional figures are mainly used for displaying objects that don’t have height or volume to represent. The figures, such as rectangles that don’t have height, could be drawn in 2D as they don’t require a z-axis, volume, and height. The 2D figures can be made by all the people who have good knowledge about geometry. The 2D forms are very easy for making flat surfaces using two axes (x-axis and y-axis).

What is 3D?

The 3D objects are prepared with the use of 3 axes, and these are the x-axis, y-axis, and z-axis. The 3D figures are more complex than the 2D ones, as they have height and volume. The visual representation of the 3D figures requires the connection of the x-axis and y-axis with the z-axis. The height of the 3D figures comes when the z-axis is connected with the x-axis and y-axis.

The volume of the 3D figures comes when they are prepared with the help of three axes. The figures such as circles and squares would not go in the category of 3D figures as they have height and volume. Not all the objects could be visually represented in 3D form, but the objects that require a z-axis could be made in the 3D form.

Main Differences Between 2D and 3D

  1. The 2D form is for the objects that need to be represented in flat or plane form. On the other hand, 3D form is mostly used for figures that require perfect dimensional representation with the help of the z-axis for its representation.
  2. The 2D form is very used for objects that don’t require a volume. On the other hand, the 3D form represents the objects with volume in themselves.
  3. In 2D form, the object’s height is not required for making the shape and structure of the object. On the other hand, the 3D objects would bring the perfect structure of the objects by focusing on their depth and height.
  4. 2D forms can be given to the circle and rectangle. On the other hand, the 3D form can be given to a cylinder, cuboid, and prism.
  5. 2D forms could not be used to give all the exact details about an object. On the other hand, 3D forms are used to give all the required details about an object.


There are many forms in which everyone can represent the object to show its structure, shape, and properties in a better manner. People use the 3D form to visually represent objects in presentations, professional works, and advertisements to give a better view of the object.

In mathematics, people use the 2D and 3D forms interchangeably for displaying various shapes and objects. Using height, volume, and z-axis makes the 3D form different from the 2D form.
