Calculate Video Bitrate, File Size, and Aspect Ratios
Every video decision is a triangle: quality, file size, and compatibility — and bitrate is the number that connects all three. Bitrate is simply how many bits each second of video contains, and the governing equation is beautifully direct: file size = bitrate × duration ÷ 8. A 10-minute video at 8 Mbps weighs about 600 MB. Know any two of the three values and the third is arithmetic, which is why this one formula quietly powers decisions from YouTube uploads to WhatsApp compression to streaming budgets. It is the first calculation professionals run and the one amateurs skip — which explains a lot of failed uploads.
The platform targets are worth memorizing because they encode years of collective wisdom. YouTube suggests around 8 Mbps for 1080p30 SDR and 12 Mbps for 1080p60, rising to roughly 35–45 Mbps for 4K SDR — uploading far above these wastes your time since YouTube re-encodes everything anyway, while far below visibly softens the result. Aspect ratio is the other half: 16:9 for standard video, 9:16 for Shorts/Reels/TikTok, 1:1 for feed posts. Cropping a 16:9 master to vertical throws away most of your pixels, so shoot with the delivery format in mind whenever you can.
Two subtleties trip people up. First, constant versus variable bitrate: CBR holds quality steady for live streaming, while VBR (two-pass) squeezes better quality per megabyte for uploads by spending bits on complex scenes and saving them on static ones. Second, resolution isn’t quality — a clean 8 Mbps 1080p encode beats a starved 4 Mbps “4K” file every time, because bitrate per pixel is what your eyes actually judge. Calculate first, encode once, and stop re-exporting the same video five times hoping it gets smaller. Your CPU, your deadlines, and your viewers will all quietly thank you for doing the math upfront.

Video Bitrate FAQs
How do I calculate video file size from bitrate?
Multiply bitrate by duration in seconds, then divide by 8 to convert bits to bytes. Example: 8 Mbps × 600 seconds ÷ 8 = 600 MB. Add ~5–10% for audio and container overhead. The same formula reversed gives you the bitrate needed to hit a target file size.
What bitrate should I use for YouTube?
YouTube’s own guidance: about 8 Mbps for 1080p30 SDR, 12 Mbps for 1080p60, and 35–45 Mbps for 4K SDR. Uploading far above these wastes upload time since YouTube re-encodes everything; far below visibly degrades quality. HDR targets run higher. When in doubt, upload slightly above the guideline — YouTube’s re-encode preserves more detail from a generous source file.
CBR or VBR — which is better?
For uploads, VBR two-pass: it spends bits on complex scenes and saves them on static ones, giving better quality per megabyte. For live streaming, CBR: a steady bitrate keeps the stream stable and platforms expect it. Different jobs, different tools.
Why does my 4K video look worse than 1080p?
Because bitrate per pixel matters more than pixel count. A starved 4 Mbps “4K” file spreads its bits across four times the pixels of 1080p, so it looks softer than a healthy 8 Mbps 1080p encode. Resolution is potential; bitrate is what delivers it.
What aspect ratio for Shorts vs regular videos?
9:16 vertical (1080×1920) for Shorts, Reels, and TikTok — full-screen on phones. 16:9 for standard YouTube and everything else. 1:1 square for feed posts. Cropping 16:9 to vertical discards most pixels, so frame with the delivery format in mind while shooting.
