Difference Between 2D and 3D (With Table)

Geometry encompasses each of these concepts. The understanding of varied shapes is what geometry has always been about. It is divided into two types: flat geometry (2D structures) and solid geometry (3D structure) (3D shapes). 

Since it works with all other flat structures, which we can draw on paper, planar geometry is sometimes called a two-dimensional configuration. Curves, line segments, polyhedral, polygons, and other structures are instances of such structures.

On the other hand, solid geometry is sometimes called a three-dimensional configuration since it works with complex or three-dimensional forms. Cones, tubes, and spheres are some illustrations of such shapes.

2D vs 3D

The main difference between 2D and 3D is that 2D structures are flat shapes and can be drawn on a sheet of paper, and on the other hand 3D structures are those which are solid and have three dimensions, and exist in real life. 

Difference Between 2D and 3D

Two-dimensional (2D) structures can be made on a smooth surface and also known as flat shapes. In other terms, 2D geometries are those that have length and width. The most common types of geometric figures include wall artwork, floor tiles, coverings, fabrics, and so on.

The 3D shapes are solid shapes created by mixing three dimensions – length, breadth, and height. Houses, cylinders, boxes, and anything else with three dimensions are illustrations of these structures in everyday life. Take into account a cuboidal tower, which is a 3D structure having length, breadth, and height.

What is 2D?

2D is an abbreviation for two-dimensional. Flat, two-dimensional objects contain only two parameters: length and width. Rectangles, triangles, squares, rhombus, and other shapes.

Flat structures, often known as closed two-dimensional or flattened plane forms, are another term for 2D shapes.

The majority of objects we come across in our daily lives can be classified as fundamental forms. The number of edges or vertices differs between different dimension shapes. The edge is a straight line that forms part of a form, and a corner, or vertex, is the point where two sides connect.

Whereas most kids are acquainted with the most basic shapes during school entry, they may not even be able to express the differences between a square and a rectangle, or a circle and a triangle, but they know how to draw them.

What is 3D? 

A 3D or three-dimensional shape parameters include length, height, and breadth (depth). 3-dimensional figures are mathematically represented on the x-, y-, and z-axes of a graph. Many of the most frequent three-dimensional structures are hemispheres, pyramids, and cuboids.

These are utilized for a variety of purposes, including 3d graphics, 3D design processes, bridges, tools, 3D graphs, charts, and so on. The 3D shapes aid in displaying the object’s depth. We employ 2 and 3 point perspective projections, as well as orthographic projection, to demonstrate 3D in construction.

The forms used in 3d structures are the globe, cube, cone, cuboid, prism, and so on. 

3D structures are created whenever the proportion of gap between two intersecting lines is considerably more significant beyond what 2D shapes can make. Cubes and cylinders are two common 3D shapes.

Surfaces that can be observed from all corners in a single image are referred to as 3D forms. They have one or even more edges, making them more than 3D as they have fewer than three surfaces and must recognize a focus point to the existence in three dimensions. 

Main Differences Between 2D and 3D

  1. However, it is obvious that a plant is two-dimensional rather than three-dimensional; that’s not always the reality. Airplanes, for example, are 3D things with 2D shapes.
  2. There are numerous noteworthy contrasts between 2D and 3D forms in our daily lives. 2D and 3D things have distinct qualities depending on how they are represented on papers and how they seem in reality.
  3. Light flowing through 2D things is broken into a more significant number of tiny waves or particles than beam passes across 3D objects. The amount of light that passes through these two sorts of things has an impact on how they appear in pictures or paintings using various lighting methods.
  4. An additional distinction between 2d and 3d structures is that the former has just one dimension, such as width or height, but the latter has three dimensions, including length, breadth, and height.
  5. 2D shapes exhibit primary effects such as basic shapes such as squares, pentagons, hexagons, and others, which aid in the creation of complicated forms in programs while sketching any 2D pattern. Instead, we should use these rectangles in a pentagon in 3D, but we can not stack them all together.
  6. While we draw in 2D structure drawing, we can not show the shadows of any item drawn on drawing paper. As reflected in other degrees or third axes, specifically Z, in that exhibition. To display the shadow, we must always depict it in 3D.


In order to understand the differences between 2D and 3D geometries, we must first understand their characteristics and applications. As a result of the preceding, it can be inferred that 2D is the inventor of drawing or patterns, which a learner must first master before progressing.

2D sketching is made up of regular forms that assist us in enhancing our hands-on drawing skills while also increasing our precision. 

Ultimately, it can be stated that both of these forms have distinct properties when it comes to the specific drawings we must choose. As a result, a student who learns all of the intricate elements of 2D and 3D is an excellent candidate for drawing.
