Projector Calculator: Calculate Projection Throw Distance and Projection Image/Screen Size for Optimal Placement
If you wish to set up a projector in a meeting room, classroom, conference room, or auditorium, then you need to be aware of a few important things. One of the most important factors is to take into account the projector’s throw distance, which is basically the distance between the lens of the projector and its screen. There’s a direct connection between the distance and the lens, which depends on the size, clarity, and brightness of the image on the screen. These days, it’s not that difficult to have the perfect image formed on the screen as the market is brimming with tools like projector throw distance calculators, which, as a result, have simplified this whole process.
Now, the question is how to use it efficiently to obtain the best result. In this blog, we’ll discuss the ways and methods by which you can make the most optimum use of a projector throw distance calculator and learn a lot of information that will make you a technophile in this subject.
How to Use the Projector Throw Distance Calculator?
Aspect Ratio: The proportional relationship between the height and the width of the screen is known as the aspect ratio. The aspect ratio defines the shape of the screen or image. It helps us understand whether or not an image is formed in the most appropriate way. It can be used to figure out the width and height proportions. Using a projector screen distance calculator, this value can be easily selected and help the viewers attain the most accurate view of projection.
Throw Ratio: One of the other important factors of a projector is the throw ratio because it measures and idealizes how much distance there should be between the projector and the screen on the basis of the width of the screen. This reading helps to obtain the size of the image that will eventually be projected at a particular distance. If you wish to try and input the values now, you can try out one of the handy and easy-to-use tools that are XTEN-AV’s Projector throw distance calculator.
Screen or Image Size: Using the projector screen calculator, you can easily specify the desired size for your screen/image. Simply feed the value of the diagonal measurement, width, or height of the screen into the screen calculator, and you can learn the ideal throw distance for your projector.

How do you calculate a projection image size when you know the projection throw distance?
Calculating a projection image becomes easier when you know the projection throw distance. If you have the value of the projector’s throw distance, you can use the formula projection image width = throw distance/throw ratio to know the projector image width.
Let’s look at the formula’s three components for better understanding:
Image Width
Image width or projected image width refers to the projected image’s size on the projector screen. It is measured diagonally from one corner to another. Its unit of measurement is generally in inches or cm. Moreover, it is essential in determining the image clarity, throw distance and throw ratio.
Throw Distance
The throw distance is the optimal distance between the projector lens and the projector screen for a clear, detailed projection/image. It is also measured typically in the same standard unit as the image width.
Throw Ratio
The throw ratio is calculated by dividing the throw distance and projection image width. It helps determine the projector’s placement or optimal image size.
Let’s understand the above formula using real-life examples.
As we know, Projection Image Width = Throw Distance/Throw Ratio
Case 1:
If you have an Epson 3-Chip 3LCD Laser with a throw distance of 133 inches and a throw ratio of 1.81, the projection image width would be 73.48 inches.
Case 2:
If you have a projector with a throw distance of 4 ft and a throw ratio of 1.5, the projection image size will be 2 ft and 8 inches.
How Accurate Are XTEN-AV’s Projector Distance Calculators?
XTEN-AV’s projector distance calculator offers precise and spot-on measurements for the projector placement. The XTEN-AV’s projector distance calculator can optimally calculate throw distance even if a different aspect ratio, throw ratio, or image size is used.
However, it is essential to ensure that external factors such as ambient lighting or screen gain do not impact the image clarity. If such factors influence the image clarity, the throw distance must be changed accordingly.
Throw Ratio
The throw ratio is an essential component that helps calculate the projector’s throw distance by assisting with the projector’s placement. Often mentioned in the product manual or specifications, it is a crucial factor that affects a projector’s distance calculation.
For example, if the throw ratio of the projector is 1.25:1, then the projector needs to be placed at a distance of 1.25 feet for every 1 foot of image width.
Screen Size
Screen size is a crucial factor that directly influences the projector’s throw distance. It means that the projector needs to be placed farther away from the screen to achieve a larger screen size.
Room Configuration
Room configuration is another important aspect that can impact the projector’s throw distance. From the shape and size of the room to the light available in it, various factors play significant roles in the projector’s throw distance calculation.
For example, a short-throw or ultra-short-throw projector works best for a small room, while a long-throw projector will project the best image for a room with a bigger size.
Screen Gain
The screen gain refers to how much light the screen reflects. The higher the screen, the more light scatters/ reflects. As a result, you can place the projector at a larger distance from the screen for a clear and vibrant light.
Projector Brightness and Ambient Lighting
Projector brightness and ambient lighting also affect the projector’s throw distance. The higher the ambient lighting in the room, the higher the projector brightness will be required for a clear and vibrant image. Subsequently, they will impact the projector’s placement, which can affect the projector’s throw distance.
Lens Shift and Keystone Correction
Lens shift and keystone correction also affect the projector’s throw distance. They allow the AV professionals to adjust the image on the screen if the projector cannot be placed as per the calculated distance or position due to any constraint. Lens shift allows the image to be repositioned while keystone automatically corrects the distorted image.
Long Throw Projector Distance Vs. Short Throw Projector Distance
There are two types of projectors one is long throw and the other is short throw. Both offer clear cut advantages and benefits as per your needs and requirements. Long throw projectors are made in such a way that they produce images over a longer distance and this makes them the best fit for larger venues or outdoor events. Short-throw projectors do the opposite by displaying images from a close focal, and hence becoming a suitable fit for smaller spaces and indoor events. It is important to note the basic operation for both types of projectors:
Long Throw Projector distance: Designed for bigger spaces where the formed image needs to be placed either at a distant screen or away from the screen. They are programmed to have a higher projector throw ratio and are best fit for auditoriums, conference halls, stadiums or large theaters.
Short Throw Projector Distance: These projectors are specifically designed for smaller places and can be useful at times when you want to place the projector closer to the screen and have a smaller, clear, and crisp picture with high resolution. With a Short throw ratio, these projectors can result in a large image just a few feet away from the screen. They become perfect examples to be used in classrooms, small meeting rooms, and rooms with limited space available.
Factors | Long Throw Projectors | Short Throw Projectors |
Throw Distance | Requires a larger throw distance | Requires a shorter throw distance |
Image Size | Suitable for larger screens | Suitable for smaller screens or spaces |
