How do you calculate projector throw ratio?

How do you calculate projector throw ratio?

For any given projector, the width of the image (W) relative to the throw distance (D) is know as the throw ratio D/W or distance over width. So for example, the most common projector throw ratio is 2.0. This means that for each foot of image width, the projector needs to be 2 feet away or D/W = 2/1 = 2.0.

How do you calculate screen size throw ratio?

Specifically, the throw ratio. This ratio tells us what size of image we can get from a certain distance away, and it can be calculated two different ways. D/W=T (distance divided by width equals throw) or TxW=D (throw multiplied by width equals distance).

Is higher throw ratio better?

Throw Ratio tells us what image size we can project from a certain distance away. For instance, a throw ratio of 1.5 indicates that for every 1 foot of image width, the throw distance must be 1.5 feet. The smaller the throw ratio, the larger the image a projector will produce at a shorter throw distance.

What is a throw ratio of 1.2 1?

This lens provides a 1.2-1.5:1 throw ratio for any of the Christie LCD projectors listed below. This means that the distance between the projector and the screen (throw distance) can be approximately 1.2-1.5 x the width of the projected image (screen).

How do I know if my projector is short throwing?

An easy way to tell if a projector is a short or a long throw is usually by the initials at the end of a model number. So for example, if it ends with ST, that typically, though not always, means that it will be a short throw projector. The opposite is true for those ending in LT.

Is a short throw projector brighter?

Are short throw projectors brighter? All major projector brands use the ‘ANSI’ Lumens standard to measure brightness, having a short throw projector does not necessarily mean it will be brighter.

Is short throw better than long throw?

The throw ratio is higher for long throw projectors and lower for short throw projectors. Therefore, a short throw projector can be placed closer to the screen than a long throw projector. What is this?

Is a higher throw ratio better?

Which is better short throw projector or long throw?

If you are looking for a home theatre experience but have rather cramped accommodation, a short throw would be the best bet. If you are giving a presentation or have the luxury of a large living space, a long throw would be better. Long throw projectors are also cheaper than short throw models.
