Planning from a real wall? Use the projector screen size calculator to upload a photo, preview the image to scale and find projectors that fit within your maximum available space. Replacing an existing projector? The projector replacement calculator checks whether this lens covers the ratio your current mount needs.

Distances are lens-to-screen, calculated from the manufacturer's stated throw ratio; allow for lens shift and mounting hardware. Always confirm against the manufacturer's installation guide before fixing mounts.

  • Our own UK-based engineers install, commission and support what we sell, and can attend site when a system needs hands on it.

  • Delivered within the UK mainland, so there is no import duty, customs charge or courier handling fee waiting for you on delivery.
