DISCAS (Display Image Size) Calculator

Choose BDM (Basic Decision‑Making) for general messaging or ADM (Analytical Decision‑Making) when viewers must inspect fine detail. Enter the values you know, pick what you want to solve, and results update live.

BDM uses %‑Element Height. Common presets:
3 % = lecture slides • 2 % = financials • 1.5 % = dense spreadsheets.

ADM replaces %EH with vertical pixel resolution (720 / 1080 / 1440 / 2160). Use it for CAD, medical imaging, or anything where users must read small detail.
