Work out a video’s file size from its length, resolution and bitrate before you export, plus YouTube’s video sizes in pixels from 240p to 4K.

Same length, other bitrates
Audio is assumed at 128 kbps AAC, YouTube's own stereo floor. A different codec or audio bitrate will shift the total by a small amount.
Enter length, resolution, and bitrate. We return the file size before you commit to the export.
This is bit-rate times duration. We do not inspect an uploaded file.
YouTube recommends 8 Mbps for 1080p at standard frame rates and 35 to 45 Mbps for 4K. Start there if you do not know your export's bitrate.
YouTube's standard is 16:9. Its recommended sizes are 426×240 (240p), 640×360 (360p), 854×480 (480p), 1280×720 (720p), 1920×1080 (1080p), 2560×1440 (1440p) and 3840×2160 (4K).
About 610 MB at YouTube's recommended 8 Mbps for 1080p, with 128 kbps audio. The same 10 minutes in 4K at 45 Mbps is about 3.38 GB.
Multiply the total bitrate by the length in seconds, then divide by 8 to get bytes. At 8 Mbps plus 128 kbps audio, one minute is about 61 MB.
It is the uncompressed estimate from the numbers you typed. Real encoders come in a little under.
