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 Dimensional and 3 Dimensions. These two forms of displaying or showing up the objects have 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 height of the object. On the other hand, in the 3D forms, the height of the object would be present to show its structure in a better manner.

2D vs 3D

The 2D form is more often used for objects, such as squares or any flat objects that can be made on a sheet of 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 the length and breadth. For 3D objects, people should be very careful about making their edges, and dimensions for giving clarity about 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.   3D figures or objects are made or drawn to make all their parts visible in a better manner. The person would be able to see the height of the 3D figures that would not be seen in the case of 2D.
Involvement of z-axis      The z-axis would not be involved or required in making a 2D figure.     The presence of the z-axis is very important for the drawing or making of 3D objects.
Presence of volume            The 2D objects don’t have volume in them as they are considered as plane figures.  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 plane figures are also tagged as the 2D figures. The best example of flat or plane figures is a circle.         The 3D figure is the only name that is given to the 3-dimensional figure. The best example of the 3-dimensional figure is the cylinder.

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 the form of 2D as they don’t require z-axis, volume, and height. The 2D figures can be made by all the people that have good knowledge about geometry. The 2D forms are very easy for making flat surfaces with the use of 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 quite complex than the 2D figures as they have height and volume. The visual representation of the 3D figures requires the connection of the x-axis, 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 circle, and square 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 z-axis would be able to 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 often used for objects that don’t require a volume. On the other hand, the 3D form is used for representing the objects that would have volume in themselves.
  3. In 2D form, the height of the object 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 cylinder, cuboid, and prism.
  5. 2D forms could not be used for giving all the exact details about an object. On the other hand, 3D forms are used for giving 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. The 3D form is very often used by people for a visual representation of objects in presentations, professional works, and advertisements for giving a better view of the object.

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