What is an Aspect Ratio?

an aspect ratio

The aspect ratio refers to the shape of a projector’s picture.

A projector screen’s aspect ratio defines the picture’s shape. 

When looking at an aspect ratio (i.e., x:y), the first number (i.e., x) refers to the picture’s width. The second number (i.e., y) defines the picture’s height. Together these two numbers describe the picture’s width and height ratio. 

For example, a screen with an aspect ratio of 1:1 is a square. Alternatively, most projector screens are automatically set to an aspect ratio of 16:9. If we divide 16 by 9, we can understand what this means using inches as an example. For each inch of the screen’s height, there are 1.78 inches of screen width. 

Remember, the aspect ratio does not refer to the image’s size but the image’s shape.

How Do I Make My BenQ Projector Picture Fit a Screen?

Alter your projector picture’s size and shape to fit the screen.

When fitting your projector’s picture to a screen, you must change the picture’s size and shape, ultimately changing the aspect ratio. 

BenQ projector screens can be resized by moving the projector. Move your BenQ projector closer to the screen to achieve a bigger picture and further away from the screen to create a smaller picture. 

How to Adjust the Projector Image to Fit Your Movie Screen Perfectly!

The projector should be placed at different distances depending on your unit’s make and model. For instance, BenQ short throw projectors must be placed closer to the screen than BenQ’s standard units. 

Every BenQ projector manual has a page dedicated to screen size, which demonstrates the distance you should place your projector to achieve your desired screen size. 

Did you lose your manual? No problem! You can download your BenQ projector manual by visiting Download Search on the official BenQ website. Insert your projector’s model number and download its manual in seconds! 

Alternatively, you can calculate the distance you’ll need to place your projector using a Projector Throw Distance Calculator. This handy tool calculates how far you’ll need to place your BenQ projector away from the screen to create a smaller or larger picture. 

How to Use Projection Calculator

Select your projector’s brand and model from the drop-down lists. Slide the projector and screen pictures closer and further away from each other, and the website will calculate the throw distance for you! 

This is a great tool if you like to plan ahead. Small rooms may not be able to accommodate certain projectors with larger throw distances. It’s always best to plan how your home theater will look and operate before investing time and money into a new projector. 

Changing the projector’s shape or aspect ratio will also help your projector’s image fit the screen. Follow our steps on changing a BenQ projector’s aspect ratio in the section How To Change Aspect Ratio On a BenQ Projector? Found above! 

Now you know how to make your BenQ projector fit any screen!

You should change your projector’s aspect ratio depending on what you’re watching. 

Different content uses various aspect ratios. 

You’ll need to alter your projector’s aspect ratio depending on what you’re watching. For example, are you watching a Hollywood movie, an indie film, or sports? All of these pictures are filmed using different aspect ratios, so it’s important to change your unit’s aspect ratio to have the best viewing experience. 

Sports are usually filmed in 16:9, while many feature-length films are formatted to 2.35:1. If you’re unsure what a movie or shows’ aspect ratio is, Googling it is always the easiest solution! 

Alternatively, setting your projector’s aspect ratio to 16:9 is the safest bet since it will be compatible with most modern media. 

Wrapping Things Up

Aspect ratios can be confusing at first, but once you understand what they are and how to use them, your viewing experience will never be the same! 

Changing the aspect ratio on a BenQ projector only takes a few minutes and can be done with the remote or using the buttons found on the top of the unit. 

Your projector’s aspect ratio and screen size can also help fit your unit’s image perfectly onto your screen, giving your home theater a truly professional feel.
