Run a real speed test
Go to speedtest.net or fast.com, run the test on the device you'll stream from, and use the upload value — not download. Run it at the time of day you stream.
Streaming Upload Speed Checker
Type your upload speed and find out if it's fast enough to stream at your chosen resolution and framerate — and what bitrate you can safely run.
Twitch, YouTube Live, Kick, Facebook, TikTok and multistream — all in one place.
Verdict
Comfortable
You can stream 1080p60 comfortably with headroom for upload spikes.

Stability notes
- Test upload during the same time window you stream — peak-hour congestion is the most common bitrate-drop cause.
- Run on Ethernet, not wifi. Wifi packet loss looks like "good speedtest, dropped frames live" because speedtest tolerates loss but RTMP/SRT does not.
How To Test & Use Your Upload Speed
2
Subtract a 30% buffer
Streaming protocols can't use 100% of your pipe. Use about 70% of measured upload — that's what the safe-bitrate number above gives you.
3
Pick the matching bitrate
Set your encoder bitrate to either the safe number or the platform recommendation, whichever is lower. Use CBR, not VBR.
Minimum Upload Speed by Resolution
| Quality | Recommended bitrate | Min upload | Comfortable upload |
|---|---|---|---|
| 720p30 | 3,500 kbps | 4.1 Mbps | 5.0 Mbps |
| 720p60 | 5,000 kbps | 5.9 Mbps | 7.2 Mbps |
| 1080p30 | 5,000 kbps | 5.9 Mbps | 7.2 Mbps |
| 1080p60 | 6,000 kbps | 7.1 Mbps | 8.6 Mbps |
| 1440p60 | 10,000 kbps | 11.8 Mbps | 14.3 Mbps |
| 4K60 | 35,000 kbps | 41.2 Mbps | 50.0 Mbps |
"Min upload" = bitrate ÷ 0.85 (95% of pipe). "Comfortable upload" = bitrate ÷ 0.7 (30% headroom). For local multistream multiply by the number of platforms.
Multistream Without Multiplying Your Upload
If you push every platform from your PC, your upload requirements multiply with each destination. StreamUps takes a single encode and fans it out to Twitch, YouTube, Kick, Facebook, and TikTok in the cloud — so you only need enough upload for one stream.
Frequently Asked Questions
Is my upload speed enough to stream?
If your upload is at least 8.6 Mbps and stable, you can comfortably stream 1080p60 at 6,000 kbps. For 720p60 you need around 7.2 Mbps. Below 5 Mbps upload, drop to 720p30. Always leave 30% headroom for upload spikes — protocols like RTMP and SRT can't safely use 100% of the pipe.
Why did my stream drop frames even though my speed test passed?
Speed tests measure peak bandwidth and tolerate packet loss; live streaming protocols don't. The most common causes are wifi interference, ISP peak-hour congestion (test at the same time you stream), background apps using the upload, and asymmetric internet plans where advertised upload is much lower than download.
How much upload do I need for multistreaming?
It depends on whether you encode locally per platform or use a cloud relay. Local multistreaming multiplies the requirement (3 platforms at 6 Mbps = 18 Mbps before headroom = ~26 Mbps comfortable). A cloud relay like StreamUps uploads once and transcodes for each destination, so you only need bandwidth for a single stream.
Should I use wifi or Ethernet for streaming?
Ethernet, every time. Wifi packet loss looks like "good speed test but dropped frames live" because speed tests average over time and tolerate retransmits, while live streaming is real-time and frame-loss is permanent. If you can't run Ethernet, use a 5 GHz wifi connection close to the router and turn off other wifi devices during streams.
Why does the platform-recommended bitrate exist if I have more upload?
Platforms cap bitrate to control viewer-side bandwidth and CDN cost. Twitch caps non-partners at 6,000 kbps regardless of your upload. YouTube and Kick are looser. Streaming above the platform cap doesn't help quality — the platform downscales your stream and may flag it for transcoding delays.
Do I need download speed to stream?
Almost none — your stream goes outbound only. Download speed matters for game updates, voice chat (Discord), and any tab you have open during the stream. As a rule, your upload stability is far more important than your download speed for live streaming.
