Before setting up a projector for a home cinema, you need to know the screen size, projector placing position, ideal viewing distance. An online Projector Calculator of Projector1 can help you to find the answers to the questions above in seconds.
What is a Projector Calculator?
The Projector Calculator of Projector1 is a useful tool to calculate the accurate projection screen size, throw distance, and optimum viewing distance.
What Can The Projector Calculator of Projector1 do?
1. Determining Proper Projector Screen Size
The Projector Calculator can help you find the proper screen size by selecting throw distance and throw ratio no matter which brand or which model.
For example:
- Throw Distance in your room: 1-3 meters
- The throw ratio of your projector: 1.2:1
- What is the Screen Size?
Now you can use the projector to calculate. By selecting the throw ratio 1.2:1, and inputting throw distance on the second blank, then clicking the Calculate button, then you can know the screen size.
After calculating with the projector calculator, we can know that the biggest screen size is 112.54. The farther the distance, the bigger screen you can have.
Of course, you can recalculate the distance or throw ratio at will by clicking Recalculate.
2. Deciding Throw Distance
If you have decided the screen size, you can use the Projector Calculator to calculate throw distance.
For example:
- Your screen size: 100 inches
- Throw ratio of your projector: 0.39:1
- What’s the Throw Distance?
By selecting the throw ratio 0.39:1, and inputting 100 on the screen size blank, then clicking the Calculate button, then you can know the throw distance is 86.64 cm.
3. Knowing about Optimum viewing distance
The Projector Calculator can help you to calculate the optimum viewing distance to get the best viewing experience.
For example:
- Your screen size: 100 inches
- Your projector throw ratio: 0.8:1
- What’s the best viewing distance?
By selecting the throw ratio and inputting the screen size of 100 inches, then clicking the calculate button, we can know that the viewing distance range is 2m-3m.

Throw Distance
Throw distance refers to the distance from the projector lens to the screen.
Viewing Distance
Viewing Distance refers to the distance between your position to the screen.
ANSI lumens
ANSI lumens reflect the overall amount of light output from a projector and represent the brightness observed on the projection image. It is a formal and widely recognized brightness unit in the projector area. ANSI stands for American National Standards Institute, a non-profit organization founded in 1918.
Contrast Ratio
The contrast ratio refers to the ratio of the luminance of the brightest shade (white) to that of the darkest shade (black) that the system is capable of producing. Put it simply, the more gradation levels from black to white, the richer the color performance of the projector. A high contrast ratio is a desired aspect of any display which is similar to dynamic range.
Resolution
The resolution reflects the pixels of the projected image. The higher the resolution, the better the sharpness and clarity of the image. Generally, 720P and 1080P are widely seen in common projectors while some high-end projector features 4K resolution.
