Full API documentation

Explanation

4K UHD (3840x2160) is 3840x2160 (8.2944 MP), while iPhone Retina 2532x1170 is 2532x1170 (2.96244 MP). The conversion factor is 8294400/2962440 = 2.79985417426.

From 4K UHD (3840x2160) to iPhone Retina 2532x1170, the calculator uses one fixed pixel-count ratio based on the exact width × height definitions of both resolution formats.

Keep the same direction when comparing render load, export scale, or equivalent frame counts, because the reverse route applies the inverse pixel-count ratio.

Method & Pixel Basis

Method basis: exact width × height definitions for both resolution grids shown in Snapshot.
Applied mapping: pixel-count ratio between 4K UHD (3840x2160) and iPhone Retina 2532x1170.
Consistency rule: snapshot, calculator, and common values table use the same pixel totals and rounding policy.

Questions & answers

Frequently Asked Questions

Does the pixel-count comparison preserve aspect ratio?

Not necessarily. It compares total pixel counts only; aspect ratio may differ between the two formats.

What is the opposite direction for 4K UHD (3840x2160) to iPhone Retina 2532x1170?

Use the mirror iPhone Retina 2532x1170 to 4K UHD (3840x2160) route; it applies the inverse relationship for the opposite direction with the same assumptions.

Can this estimate performance impact?

It helps approximate pixel workload differences, but real performance also depends on GPU, game/app settings, and pipeline overhead.
