THE SPECS THAT MATTER
Points and pixels with the scale factor. Pixel density. Aspect ratio. And safe-area insets, top and bottom — the numbers you actually need to lay out a screen, and the ones almost nobody publishes.

TOOLS
• Aspect ratio lock — set a ratio, change one side, the other follows
• DPI calculator — real pixel density from any diagonal
• Side-by-side compare — two resolutions, pixel counts, megapixels
• Favorites, and your own custom sizes
• Export the whole catalog as JSON or CSV
