Streaming Bitrate Calculator
Find the optimal streaming bitrate for your resolution, frame rate, and upload speed.
Includes data usage estimates per hour.
Streaming Bitrate determines the quality of your video stream. A higher bitrate means better image quality but requires more upload bandwidth.
What is bitrate? Bitrate is the amount of data transmitted per second, measured in kilobits per second (kbps) or megabits per second (Mbps). For streaming, this is the video data your computer encodes and sends to the streaming platform (Twitch, YouTube, etc.).
Recommended bitrates by resolution and frame rate:
| Resolution | 30 fps | 60 fps |
|---|---|---|
| 720p (1280×720) | 2,500-4,000 kbps | 3,500-5,000 kbps |
| 1080p (1920×1080) | 4,500-6,000 kbps | 6,000-9,000 kbps |
| 1440p (2560×1440) | 8,000-12,000 kbps | 12,000-18,000 kbps |
| 4K (3840×2160) | 20,000-30,000 kbps | 30,000-51,000 kbps |
Encoding matters: Different encoders handle the same bitrate differently.
- x264 (CPU): The gold standard for quality per bitrate. Uses your CPU, which can impact game performance. Best quality at lower bitrates.
- NVENC (GPU): Uses NVIDIA’s dedicated encoding chip. Minimal performance impact. Requires roughly 15-20% higher bitrate than x264 for similar quality.
- AV1 (Next-gen): The newest codec, available on RTX 4000+ and newer AMD GPUs. Achieves similar quality to x264 at about 30% lower bitrate. Ideal for bandwidth-limited streamers.
Upload speed requirements: Your upload speed must be significantly higher than your streaming bitrate. A good rule of thumb is to use no more than 75% of your available upload speed for streaming. This leaves headroom for other network activity, including game data.
For example, if you have 10 Mbps upload, your maximum safe streaming bitrate would be about 7,500 kbps (7.5 Mbps). However, you also need about 1-2 Mbps for game networking and general overhead.
Data usage: Streaming consumes significant bandwidth over time. At 6,000 kbps, you will use approximately 2.7 GB per hour of streaming. Over a 4-hour stream, that is nearly 11 GB of upload data. This can matter if your internet plan has data caps.
Platform limits:
- Twitch recommends a maximum of 6,000 kbps for standard partners and 8,500 kbps for some affiliates.
- YouTube supports up to 51,000 kbps for 4K streams.
- Lower bitrates are more accessible to viewers with slower internet connections.
Tips for best quality:
- Test your stream using a service like Twitch Inspector or a private YouTube stream before going live.
- If your stream looks pixelated during fast motion (games, sports), increase the bitrate or lower the resolution.
- A stable connection matters more than raw speed. Wired Ethernet is always preferred over Wi-Fi for streaming.
