VRHow / VR Tools / VR PPD & FOV Calculator
Interactive VR PPD (Pixels Per Degree), FOV & GPU Fillrate Workbench
Optical Clarity Bench Overview: Select any two headsets or dial in custom per-eye resolution, field of view, refresh rate, barrel-distortion supersampling (1.0x–1.6x), and foveated rendering savings below. The workbench renders a scaled SVG Field-of-View overlap diagram, a live HTML5 Canvas subpixel sharpness simulation, and side-by-side GPU pixel fillrate telemetry.

Frequently Asked Questions
How is PPD (Pixels Per Degree) calculated in VR headsets?
Average horizontal PPD is calculated by dividing a headset's per-eye horizontal pixel resolution by its horizontal field of view in degrees. Peak central PPD is typically 15% to 28% higher due to optical magnification at the center of the lens.
Why does SteamVR 100% render resolution exceed the headset's physical panel resolution?
VR lenses introduce pincushion distortion. To counteract this, the GPU renders a barrel-distorted image at roughly 1.3× to 1.4× the physical width and height of the display panel (~1.96× total pixels) so that the center of the lens maintains 1:1 native pixel sharpness.
