📱 Foldable Form Factor & Aspect Ratio Simulator

For the default inner split-screen scenario, the source assigns area one hundred forty-eight point two square centimeters to its passport-labeled device and one hundred forty-one point eight to its tall-labeled device. Fixed waste is five and eighteen percent. Multiplying by remaining fraction gives one hundred forty point seven nine and one hundred sixteen point two seven six usable square centimeters. Both bars use three pixels per square centimeter. These dimensions and waste percentages are saved assumptions, not measured device specifications or app layout tests. Selecting inner sixteen-to-nine video assigns forty-two percent unused area for the passport-labeled case and forty-nine for the tall-labeled case. The source does not derive these percentages from its aspect-ratio geometry. Bars use eight pixels per percentage point. Other scenarios also choose fixed waste constants, and reachability strings remain fixed. Treat this as a scenario table, not measured letterboxing, ergonomic reach, or product advice. At inner hinge angles from seventy through one hundred ten degrees, inclusive, the code subtracts ten waste percentage points for the passport case and five for the tall case, then floors at zero. In the video scenario, passport waste changes from forty-two to thirty-two. Both bars use ten pixels per percentage point. At sixty-five or one hundred fifteen the fixed subtraction does not apply. This threshold heuristic affects usable-area arithmetic; it does not simulate hinge mechanics or prove an ergonomic improvement.
