The PT-FRZ60 has a manual lens zoom and focus adjustments are made using a ring surrounding the lens. It has a zoom range of 2:1 and a throw ratio of 1.46 to 2.94:1. The throw distance can quickly be calculated using the width of the screen. For example, on a 100" wide image, the throw distance would be between 146" and 294".
To make it easier for installer, Panasonic has a Throw Distance Calculator on their website can provide the throw distance easily.
Since diagonal screen size is usually listed to help eliminate the need for you to do the math, below is a basic chart for your reference.

The PT-FRZ60 has both horizontal and vertical optical lens shift which dramatically increases installation flexibility. It also makes the projector a great choice for someone trying to replace an existing projector.

One of my favorite features on the PT-FRZ60 is the lens shift lever. While most projectors have wheels/knobs to manually adjust H/V lens shift, the Panasonic adjust lever looks like a little joystick. The lever makes it quick and easy to precisely align the projected image to the screen.
