Upload speed for streaming

How much upload speed do you need to stream?

You need enough upload speed for video bitrate, audio bitrate, and a safety margin. The safety margin matters because speed tests show a best-case snapshot, not what your connection can hold during a whole stream.

Use the bitrate calculator Twitch bitrate guide

The quick answer

For a stable beginner stream, plan for at least 5 Mbps upload for lower settings, 8 to 10 Mbps upload for many 720p60 or 936p60 setups, and more than 12 Mbps upload if you want room to test higher bitrates. More upload does not automatically make the stream better, but it gives you safer choices.

If your upload speed changes a lot from test to test, use the lowest normal result, not the best one. A connection that sometimes tests at 12 Mbps and sometimes tests at 7 Mbps should be treated like a 7 Mbps connection until you fix the inconsistency.

Use this formula

Usable stream budget = upload speed in Kbps x 0.70. Then subtract audio bitrate to estimate video bitrate. The 0.70 leaves 30% headroom. You can use less headroom on a very stable wired connection, but new streamers usually regret cutting it too close.

  • 5 Mbps upload: about 3500 Kbps usable, or about 3340 Kbps video after 160 Kbps audio.
  • 8 Mbps upload: about 5600 Kbps usable, or about 5440 Kbps video after 160 Kbps audio.
  • 10 Mbps upload: about 7000 Kbps usable, or about 6840 Kbps video after 160 Kbps audio.
  • 12 Mbps upload: about 8400 Kbps usable, or about 8240 Kbps video after 160 Kbps audio.

The stream bitrate calculator does this math for you and lets you change the headroom percentage.

What settings fit common upload speeds?

  • 3 to 5 Mbps: start with 480p30 or 720p30. Keep overlays light and avoid Wi-Fi if possible.
  • 6 to 8 Mbps: try 720p60 or 720p30 with more image detail. Keep video bitrate conservative if other people share the connection.
  • 9 to 12 Mbps: try 720p60 or 936p60 first. Test 1080p only after the lower setting is stable.
  • 12 Mbps and up: you have room to test, but platform guidance, encoder quality, and viewer experience still matter.

Platform recommendations and limits change, and some channels or accounts may have different options. Use this as a practical upload-speed check, then confirm current platform guidance before publishing a final preset.

If your upload speed should be enough but OBS still struggles

Upload speed is only one bottleneck. Dropped frames usually point to network issues, while skipped frames and rendering lag point to encoder or GPU load. If OBS names the problem, follow that label instead of changing random settings.
