Aspect Ratio & Screen Size Calculator
This calculator turns a display diagonal and aspect ratio into the numbers a drawing needs: width, height, and area, from H = D over the square root of AR squared plus one. Add a resolution to get pixel density and pixel size, which is what legibility and camera-capture questions actually turn on. A diagonal alone never specifies a screen; a 75-inch 16:9 panel and a 75-inch 21:9 panel are different walls.
This runs on the same engine as the agents
On the calculator the math stands alone. Inside Avria it runs across a whole room, cites the clause behind every call, and lands in a complete BOM you can check line by line.
