Engineering inputs

Start here: Image width and height

* Required for this basic result. Optional fields add other results. Only enter known values.

What else may be needed?

Enter diagonal + aspect ratio, or enter known width and height instead. The stars follow the dimension route you use.

Mounting and viewing checks also need the relevant heights and viewing distance. Image size alone does not verify readability.

Still to enter: Image diagonal; Aspect ratio width; Aspect ratio height.

Quick calculator

Independent calculations with only the inputs they need. Use the room workspace for seats, obstructions and synchronized views.

Calculation geometry

Enter the required geometry or measurements to draw this calculation. No sample dimensions are assumed.

Method & limitations

Image geometry and ray intersection. AVIXA V202.01:2026 BDM/ADM sizing is unavailable pending verified official methods.

Calculation results

Preliminary engineering. Review the basis before using a value.

Image width

Additional Input Required

— m

W = r × H. Enter width/height or diagonal and aspect ratio.

Image height

Additional Input Required

— m

H = diagonal / √(r² + 1); diagonal entered in inches.

Image centre height

Additional Input Required

— m

Image geometry only; housing and bracket clearance are separate.

Image top height

Additional Input Required

— m

Bottom edge + image height.

Image-to-ceiling gap

Additional Input Required

— m

Does not include display housing or mounting hardware. Negative = image exceeds ceiling.

Centred horizontal viewing angle

Additional Input Required

— °

Applies to an eye centred on the image horizontal axis.

Vertical viewing angle

Additional Input Required

— °

Eye-to-upper/lower-edge angle.

BDM / ADM minimum image size

Engineering Verification Required
