How to calculate projector throw distance

Finding the instalation point is important to make sure you do not wire up a projector in the wrong position. Every projector comes with a number called the throw ratio which can be used to calculate the instalation point of a projector. Some will even have a range when the projector has some zoom it will be able to be installed in this range between two points.

The throw ratio will usually be a number followed by a colon then another number. The first number represents the distance and the second represents the screen width. For example 1.15:1 if you have a two metre wide image would mean the instalation is at 2.3metre (2metre width X 1.15 ratio = 2.3m)

If it is a range ratio like 1.15 - 1.5 for a 100inch 16:9 (2.13m wide) screen then the calculations would look like this:

1.15 X 2.13m = 2.45 metres - Closest installation point
1.50 X 2.13m = 3.20 metres - Furthest installation point

Most manufacturers will then advise to round these numbers up and down by 5% in case there is a slight variance among models. After rounding it would be 2.6metre to 3.1metres.
