There are a couple of ways of calculating the perfect lens size.
Simply enter the rough distance between the camera and the subject you wish to capture plus the focal length of the lens you are considering. The handy tool will then give you estimates on the horizontal and vertical distances you can expect to cover with a 1/3” or a 1/4” CCD camera.

You can do it in two ways.
The old fashioned, time consuming way of using a formula such as this f = c x d/w where f = lens size needed (mm), c = chip width (mm) 1/3” CCD = 4.8mm or 1/4” CCD = 3.2mm, d = distance of object from camera (m) and w = width of view required (m)
If that seems a little too complicated you could always do it the easy way with our Free Lens Calculator tool. Just enter the distance from the camera to the object you want to monitor and the focal length of the lens you’re considering. The tool will instantly tell you what you can expect to capture.
