Stream Bitrate Calculator

Why Does Stream Bitrate Matter?

Bitrate is the amount of data you send to a streaming platform per second. It directly affects the visual quality of your stream. If your bitrate is too low for your chosen resolution and frame rate, your stream will look pixelated or blocky during fast-paced movement. If it is too high, viewers with slower internet connections will experience constant buffering.

Finding the Sweet Spot

A common mistake is trying to push 1080p 60FPS on a lower bitrate. It is generally better to stream at a lower resolution (like 936p or 720p) with a sufficient bitrate than to stream at 1080p with an inadequate bitrate. 936p (1664x936) is a popular "sweet spot" resolution for Twitch as it looks very close to 1080p but handles 6000 kbps much better during fast gameplay.

Upload Speed Requirements

To maintain a stable stream, you should never max out your internet's upload speed. Our calculator factors in a 30% overhead margin to account for game data, voice chat, and internet fluctuations. For example, if your total bitrate (video + audio) is roughly 6 Mbps, you will ideally want an upload speed of at least ~8 Mbps dedicated to streaming.

Platform Differences

• Twitch: Has a soft cap of 6000 kbps for non-partners. Pushing above this (up to ~8000 kbps) is sometimes possible, but risks viewers not receiving transcoding options (quality options like 720p, 480p), forcing them to watch at source quality which may cause buffering.
• YouTube: Allows for significantly higher bitrates and supports 1440p and 4K streaming. YouTube will automatically transcode your stream, so you can push as high a bitrate as your internet allows to get the best quality.
• Kick: Generally supports up to 8000 kbps for standard streamers. Like Twitch, sticking to 6000-8000 kbps is recommended for 1080p 60FPS content.
