Your internet speed — specifically your upload speed — is the foundation of a stable live stream. This guide covers exactly how much speed you need for every platform and resolution.
Quick Answer
| Stream Quality | Bitrate | Min Upload Speed | Recommended Upload |
| 720p 30fps | 2,500–4,000 Kbps | 5 Mbps | 8 Mbps |
| 720p 60fps | 3,500–5,000 Kbps | 7 Mbps | 10 Mbps |
| 1080p 30fps | 4,500–6,000 Kbps | 8 Mbps | 12 Mbps |
| 1080p 60fps | 6,000–9,000 Kbps | 10 Mbps | 15 Mbps |
| 1440p 60fps | 12,000–15,000 Kbps | 18 Mbps | 25 Mbps |
| 4K 30fps | 25,000 Kbps | 35 Mbps | 50 Mbps |
| 4K 60fps | 40,000 Kbps | 55 Mbps | 75 Mbps |
Upload Speed vs Download Speed
- Upload speed is what matters for streaming. It determines how much data you can send to the streaming platform.
- Download speed doesn't directly affect your stream quality, but you need some for chat, alerts, browser sources, and game downloads.
Most ISPs advertise download speed prominently. Your upload speed is usually much lower — check it at speedtest.net or fast.com.
Speed Requirements by Platform
Twitch
Twitch caps most streamers at 6,000 Kbps. You need:
- Minimum: 10 Mbps upload
- Recommended: 15 Mbps upload (for headroom)
YouTube Live
YouTube supports up to 51,000 Kbps and benefits from higher bitrates:
- 1080p 60fps: 15 Mbps upload minimum
- 4K 60fps: 60+ Mbps upload minimum
Kick
Similar to Twitch with an 8,000 Kbps cap:
- Minimum: 12 Mbps upload
- Recommended: 18 Mbps upload
What About Multistreaming?
If you stream to multiple platforms simultaneously (Twitch + YouTube), you need upload speed for each stream combined:
- Twitch (6,000 Kbps) + YouTube (9,000 Kbps) = 15,000 Kbps
- Recommended upload: 25+ Mbps
Alternatively, use a cloud multistreaming service like Restream that re-broadcasts from their servers — this only requires bandwidth for one stream.
Wired vs WiFi
Always use a wired Ethernet connection for streaming. WiFi introduces:- Packet loss — causes stream stuttering and dropped frames
- Latency spikes — causes buffering for viewers
- Bandwidth fluctuations — your effective speed varies constantly
Even if your WiFi speed test shows 100 Mbps, the connection stability is far worse than a wired connection. A 20 Mbps wired connection is more reliable for streaming than 100 Mbps WiFi.
How to Test Your Connection
1. Run a speed test at speedtest.net — note your upload speed
2. Use our Bandwidth Calculator to see which stream qualities your speed supports
3. Do a test stream on Twitch/YouTube for 30 minutes and check for dropped frames in OBS
What If My Upload Speed Is Too Low?
- Lower your resolution: 720p 60fps at 4,000 Kbps looks better than 1080p 60fps at 4,000 Kbps
- Lower your bitrate: Use our Bitrate Calculator to find the sweet spot
- Use a more efficient codec: HEVC or AV1 (if your platform supports it) gives better quality at lower bitrates
- Upgrade your internet plan: Many ISPs offer higher upload speeds for a small premium
- Use a wired connection: If you're on WiFi, switching to Ethernet may solve your issues
Connection Types and Typical Upload Speeds
| Connection Type | Typical Upload | Good for Streaming? |
| DSL | 1–10 Mbps | 720p only |
| Cable | 5–35 Mbps | 1080p ✓ |
| Fiber | 100–1000 Mbps | 4K ✓✓✓ |
| 5G Home | 20–100 Mbps | 1080p–4K ✓ |
| Starlink | 5–20 Mbps | 720p–1080p (variable) |
Bottom Line
For most streamers targeting 1080p 60fps on Twitch, 15 Mbps upload is the sweet spot. If you're on YouTube and want to push 4K, you need 50+ Mbps. Always test with a real stream before going live.
