depth incl. screen and projector 60 cm.

My LS800W projector is standing on the floor - I moved it around and measured the following distances to the wall (from the front edge of the projector) and picture widths: 12cm - 2.25m; 15cm - 2.43m; 20cm - 2.73m; 25cm - 3.03; 31.5cm - 3.43m.
The projector has a depth of 34cm, with small feet at the bottom 3cm from the outer edge.

Projection height: The projector has a height of 15.5cm and the image starts 14.5cm to 24.5cm above the projector at projecting distances.

The projection is excellent, whether from pre-installed apps, TV, smartphone, Playstation or PC.

Ca 15cm

Furniture normally 5-6cm from the wall
Projector approx. 15cm from wall= 100"
Projector approx. 20cm from wall= 120"

The following specifications are for projection format 120 inches (16:9). Distance from the wall to the back of the projector is exactly 56 cm. Of this, the thickness of the screen is 3.3 cm. This results in a net distance from the back of the projector to the projection surface of 52.7 cm...

My sideboard is 45 cm deep and the projector is positioned on the sideboard so that the speaker line is flush with the outer edge of the sideboard. The picture is the size you require.
