A projector throw ratio is a formula that allows us to calculate the image width or throw distance even if we know what the measurements are.
The resolution also depends on the throw ratio. If you are sitting too close, or sat too far from the screen, your picture will pixelate, meaning it will look like there are little dots all over it. Back in my day, we didn’t have pixels –

What is a Projector Throw Ratio?
A projector’s throw ratio is the distance from the projector to the screen divided by the width of the projected image. Another way to think about it is how long the projector’s lens will be compared to the width of the projected image.
For example, a projector with a 1.2 throw ratio will project an image that is twice as wide as it is long, for example, a 4×3 image that is 2 feet wide or a 16×9 image that is 4 feet wide.

How is the throw ratio calculated?
The throw ratio is calculated as the ratio of maximum distance and the actual distance. It is determined by the ratio of the final velocity in the horizontal axis and the initial velocity in the horizontal axis.
Since the vertical and horizontal throw ratio are different from each other, it is not easy to define the nature of the throw ratio. That is why the horizontal throw ratio is usually defined as the vertical throw ratio. Did you check our latest post about : Best Budget Short Throw Projector – Top 5 with Buying Guide

All you need to know about resolution
When it comes to getting the best possible picture from your projector, resolution is key. Here’s everything you need to know about resolution, including the formula for working out just what to buy.
The resolution of your home cinema projector is a hot topic – especially when you start looking at the latest models. The resolution of a projector is a very important factor in how clear the picture will be, and is often the biggest determining factor in the price.
Here I’ll explain what resolution is and how you can work out just what to buy to get the best possible picture. For those who are wondering, the resolution of a projector is measured in dots per inch (dpi).
The importance of throw ratio and resolution
The throw ratio of a projector is a measurement that allows us to calculate the image width or throw distance of the projector, even if we know what the measurements are.
The resolution also depends on the throw ratio. If you are sitting too close, or sat too far from the screen, your picture will pixelate, meaning it will look like there are little dots all over it. Back in my day, we didn’t have pixels –

FAQ’s
1. What is the ideal throw ratio for my projector?
The ideal throw ratio for your projector will depend on the size of the room and the desired screen size.

2. Can I use a short throw projector in a large room?
Short throw projectors are generally more suitable for smaller rooms or limited spaces. While you can use them in larger rooms, it might result in compromised image quality or reduced screen size.
3. What should I do if my projector’s throw ratio doesn’t match my screen size preference?
If the throw ratio of your projector does not perfectly match your desired screen size, you can consider using additional equipment such as a lens adapter or moving the projector closer or farther from the screen.
4. Is the throw ratio the only factor to consider when setting up a projector?
No, there are other factors to consider, such as brightness, resolution, and connectivity options. It is important to evaluate all the specifications and capabilities of a projector to ensure it meets your specific requirements.
5. Can I use a long throw projector in a small room?
While it is possible to use a long throw projector in a small room, it may result in a larger projection distance, making it challenging to achieve the desired screen size. It is advisable to choose a projector with a throw ratio suitable for your room size.
