Full API documentation

Explanation

UltraWide 3840x1600 is 3840x1600 (6.144 MP), while DCI 4K (4096x2160) is 4096x2160 (8.84736 MP). The conversion factor is 6144000/8847360 = 0.694444444444.

From UltraWide 3840x1600 to DCI 4K (4096x2160), 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 UltraWide 3840x1600 and DCI 4K (4096x2160).
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 UltraWide 3840x1600 to DCI 4K (4096x2160)?

Use the mirror DCI 4K (4096x2160) to UltraWide 3840x1600 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.
