What Is Frame Loss Ratio?
Frame loss ratio measures how many frames get lost or dropped during data transmission. Every time you stream a video, play an online game, or make a video call, your device sends thousands of tiny "frames" of data. Sometimes these frames don't make it to their destination.
That annoying lag in your game? Those blurry video calls? The buffering on your stream? These are often caused by frame loss. The ratio tells you what percentage of your data is disappearing along the way.
Understanding frame loss helps you know if your connection is good enough for what you're trying to do, or if you need to troubleshoot your network.
Frame Loss Ratio Formula
Loss Ratio Calculation Formula
Frame Loss Ratio (%) = (Lost Frames ÷ Total Frames Sent) × 100
This simple formula shows what percentage of your frames didn't make it:
- • Lost Frames: Frames that were dropped or never arrived
- • Total Frames Sent: Total number of frames transmitted
- • Result: Percentage of lost data
Example: 50 lost frames out of 10,000 sent = (50 ÷ 10,000) × 100 = 0.5%
Frame Loss Ratio Examples
Performance Levels
| Total Frames Sent | Lost Frames | Loss Ratio | Performance |
|---|---|---|---|
| 10,000 | 5 | 0.05% | Excellent |
| 10,000 | 50 | 0.5% | Good |
| 5,000 | 100 | 2% | Poor |
| 2,000 | 100 | 5% | Very Poor |
Lower percentages mean better performance. Gaming typically needs <1%, streaming <0.1%, and video calls <0.01%.
Frame Loss FAQs
What's the difference between frame loss and packet loss?
Frames are data packets grouped together. Frame loss is essentially packet loss at the application level.
Can frame loss be fixed?
Often yes - try wired connections, update drivers, check WiFi interference, or contact your ISP.
Why does frame loss matter more for some activities?
Real-time activities like gaming and calls need consistent data flow. Downloads can tolerate more loss through retransmission.
