Mathematical Formula & Step-by-Step Guide
Primary mathematical equation used by this model:
Bitrate (kbps) = (Width × Height × FPS × 0.085 BPP) / 1,000
- Configure your primary input (Stream Output Width (px - 1920 or 1664), baseline set to 1,920) using either the direct numeric box or synchronized range slider.
- Adjust the remaining parameters (Stream Output Height (px - 1080 or 936), Stream Frame Rate (30 or 60 FPS)) to mirror your exact scenario.
- Examine the primary output alongside the secondary breakdown metrics and the 6-tier benchmark comparison table below.

Frequently Asked Questions — OBS Stream Bitrate
What mathematical formula does the OBS Twitch & YouTube Live Streaming Bitrate (BPP) Calculator use?
This calculator implements the verified relationship: Recommended Bitrate (kbps) = (Width × Height × FPS × 0.10 BPP) / 1,000. Each variable (Stream Output Width (px - 1920 or 1664), Stream Output Height (px - 1080 or 936), Stream Frame Rate (30 or 60 FPS)) is evaluated in real time using double-precision floating-point arithmetic so there is zero rounding drift across multi-step scenarios.
How does changing Stream Output Width (px - 1920 or 1664) impact the final result?
Stream Output Width (px - 1920 or 1664) acts as the primary driver in this model (default baseline: 1,920). Use the Reference Benchmark Table on this page to compare how scaling Stream Output Width (px - 1920 or 1664) from conservative to aggressive levels changes both the primary outcome and secondary ratios.
