Sizes are physical pixels — what Screen.width and Screen.height return, and what CanvasScaler actually works in. "Target" is how large your 120 px reference-space button ends up in millimetres on the real panel; 9 mm matches Apple's 44 pt and Google's 48 dp, and 7 mm is the practical floor.

Rows marked ~ are 2025+ models whose exact panel specs I could not verify — treat them as representative of their size class, and use the custom device row for anything you actually ship against.

Touch targets below the floor

iPhone SE (3rd)6.5 mm

A 120 px button in reference space lands under 7 mm on these panels. Either raise the button size, or give the smallest devices a dedicated layout — scaling alone will not fix it, because the scale factor is what shrank it.

Match 0 locks to width (UI keeps its horizontal size, vertical overflows), match 1 locks to height. Anything between trades one for the other in log space.
