The XGIMI MoGo 3 Pro has a throw ratio of 1.2:1, i.e. you need 1.2 metres of projection distance for every 1 metre of image width. A distance of approx. 1.0-1.1 metres is required to project an image diagonal of around 40 inches (approx. 1 m image width).

Answers below fit so far. It's a great device. From my point of view, it already adapts itself. I haven't used it much yet.
