There are two kinds of projection systems. Used in the commercial and domestic use of the projector. One of the most famous projection types is a front projection which is widely used. And the other one is rear projection. Today in this article. We compare both the projection-type front projection vs rear projection.

Because there are lots of people out there. Who wants to use the projector for the home theater and event or stage. But they are confused about which projection method is perfect for them.

Both the projection types have their advantages and disadvantages. So it would be better. We know one by one what these projection types are. 

And also about these pros and cons. And also know about the difference between them by comparing. Both the projection type. The major difference between both projections is that. The front projection reflects the light from the screen. While rear projection transmits the projected light through the screen.

What is front projection?

In the front projection, the projector is positioned with the viewer. The front area of the screen. The projector can hang up with the ceiling. Or put it over the AV chassis, or it might be put over the table.

Then the projector projects the projection light over the screen. And then light reflects towards viewers. It is called front projection. In the front projection, light is reflected by the screen.

What is rear projection? 

In the rear projection, the projector is positioned behind the projector. Opposite from where the viewer sits. And in the rear projection light transmits towards the viewers. Not reflected like front projection. 

Comparison:Front projection vs Rear projection. 

So let’s see what is the difference between the front projection and rear projection.

Need a special screen

For the front projection, you will need a normal screen. Which is backed with the material. Which doesn’t let the light fall on the other side of the screen or let reflect the projected light. This type of screen is normal in commercial and domestic projection. Even on the normal smooth white wall, you can do front projection easily. And you will get a good image quality.

But here the screen need is different for the rear projection. For the rear projection, you will need the screen. Which transmits the light or lets pass the light from the screen to the audience. So the audience can see the projection. 


There is different space needed for both projection types. Honestly, for the rear projection, you will need more space than the front projector. In the rear projection, you will need the space different for the projector placement. And different for the viewers sitting. 

While for the front projection. You can place the projector and audience in the same direction or place. The front projection setup needs less space. It will be optimal for you. If you have a space issue for the projection.

Ambient Light 

In the front projection. You will need the dark environment to ensure that you have a good image on the screen. Because of the presence of ambient light. Front projection can’t provide you the best image quality. The front projection will suffer from ambient light.

For the ambient light rear projection will be the optimal choice for the projection. Because with the rear projection you will get better contrast and color saturation.


The rear projection screen transmits light in both directions. The projected light. Which provides a bright image in rear projection. As well, the rear projection projector is positioned behind the screen. For this type of projection setup. We can make an isolated environment. And put projector and screen inside that. So there will be less loss of brightness. And we go bright projection.

In the front projection. Brightness depends upon projector output and screen gain. If these things are good then the image will be bright. When you use the front projection in the absence of ambient light. Not ideal for the ambient light projection (The image will be viewable, not good. Depend upon lumens and gain).

Viewing Angle 

In the front projection, the viewing angle is mainly affected by the projector screen gain. The better or more the projector screen gain you have. The better viewing angle you will get in the front projection. And for better visuals, it also depends upon. Where is the audience has sat? It’s off the reflective angle or inside the reflective angle (reflective angle depends upon the reflective angle your screen provides 160 or 180 degrees).

And in the rear projection. Your viewing angle depends upon the type of projector screen material. And screen light diffusion ability. How your projector screen material diffuses the projected light. Specifically, if you have dark screen material. Then it will give you a better viewing angle.


Front projections don’t survive in the ambient light. The image created in the front projection will be washed out. Because the front projection created image is not dependent on the projection screen gain. 

If you use the rear projection. It will give you a better contrast than the rear projection. Ambient light coming from a different direction on the screen doesn’t affect the image. Because light goes through the screen or rear projection transmits the light. Not reflected from the screen.

Home Theater

Front projection vs Rear projection: Which is better for the home theater?

If your home theatre room is a completely ambient light control room. And your room has dark paint. Its curtains are dark. The front projection is king for the home theater room. You don’t need to go with the rear projection.

But some people have rec rooms with a projector. In this case, you should go with the rear projection. It will give you the maximum performance of the projector.

Feel and Look

The big problem with the front projector is that. No matter where you are doing the projection on the stage, office, and home theater. When someone comes between the projection. You will see the shadow of that person or object on the screen. It can be irritating for some people. And during the front projection, people put the projector and speakers in front of the screen with the viewers. Because of that, the front area of the projection becomes Helter Skelter.

And on the other hand, if you are doing the rear projection. You will position all your equipment. Behind the projector screen. Your front area will be clean and look good. You can put the projector and speakers behind the projector screen. No projection equipment in front of the projection screen. And no worry about someone who comes in the area of the projection light. 

Rear projection: Pros and Cons. 

  1. Pros
  2. During the rear projection. You can easily walk around the projection. No shadow will appear on the screen. 
  3. The front area of the rear projection is clean. No helter skelter area in front. Which is good. Because the projector and speaker will be situated behind the screen.
  4. If you are using the acoustically transparent projector screen. Then you can put your projector and speaker behind the rear projection screen.
  5. Rear projection is a enemy of ambient light. If you are using the rear projection your projected image quality in the presence of ambient light is better than the front projection.
  6. Rear projection also cancels the projector fan noise.

  1. Cons
  2. During the rear projection make sure you find your perfect place from where you can sit or stand. And see the screen. Because rear-projection doesn’t have a good viewing angle.
  3. And there are chances you may see some hot spotting on the screen.
  4. If you are using the rear projection film screen. It might don’t let the projection light spread over the screen properly.
  5. You will need special projection screen for rear projection.

Front projection: Pros and cons. 

  1. Pros
  2. Front projection should be the optimal choice. If you are thinking of setting up the projector screen (In certain conditions).
  3. You can do a front projection on any smooth white surface. 
  4. Front projection is perfect when you don’t have much space between the projector and screen.
  5. The front projection has a better viewing angle. Then rear projection.

  1. Cons
  2. Front projection is not good for the rec room. If youare using as a home theater. 
  3. Front projection can’t survive in the presence of ambient light. The reason why you get less bright image than the rear projection.
  4. The front projection front area is a helter-skelter.

Conclusion: Front vs Rear projection.

So which is better: font projection or rear projection? No projection method is good or bad. It depends on the environment, place, and you. The environment is full of ambient light or not.
