Video Bitrate Calculator
Choose a mode. Either enter a bitrate and length to estimate the file size, or enter a target size to find the bitrate that fits. The table lists YouTube’s published recommended upload bitrates.
| Resolution | SDR, standard frame rate (24, 25, 30) | SDR, high frame rate (48, 50, 60) |
|---|---|---|
| 2160p (4K) | 35–45 Mbps | 53–68 Mbps |
| 1440p (2K) | 16 Mbps | 24 Mbps |
| 1080p | 8 Mbps | 12 Mbps |
| 720p | 5 Mbps | 7.5 Mbps |
| 480p | 2.5 Mbps | 4 Mbps |
| 360p | 1 Mbps | 1.5 Mbps |

How to use it
- Pick whether you are finding file size or bitrate.
- Enter the length and either the bitrate or target size.
- Compare with the recommended bitrates below.
Frequently asked questions
How is file size calculated?
Size equals (video bitrate plus audio bitrate) times duration, divided by eight. Real files differ a little because of containers and variable bitrate.
What bitrate does YouTube recommend?
See the table below, taken from YouTube’s recommended upload settings. For 1080p at standard frame rates it is 8 Mbps.
