How big is a 1-minute video? Size table by resolution
Updated: November 10, 2026
Knowing how big a video is helps you choose the quality, work out how much space you need and how long it will take to upload. Size doesn’t depend only on resolution: it mostly depends on bitrate (how much data per second the video uses). These are rough figures for the most common cases.
Rough table (H.264 video + AAC audio)
These are approximate: every camera, app and editor uses a different bitrate, and high-motion scenes take more space.
- 480p: about 15–20 MB per minute.
- 720p: about 30–40 MB per minute.
- 1080p exported for the web: about 55–90 MB per minute.
- 1080p recorded on a phone: about 100–130 MB per minute.
- 4K recorded on a phone: about 300–400 MB per minute.
How to calculate it yourself
Size (MB) ≈ bitrate in Mbps × seconds ÷ 8. For example, a 10-minute video at 8 Mbps: 8 × 600 ÷ 8 = 600 MB, plus a little for audio.
If you’d rather not do the math, use the video size calculator: pick length and quality and it tells you the size and how long the upload will take.
Why phone videos are so big
- Phones record at a high bitrate to keep detail for editing later.
- Exported for the web at a reasonable quality, the same video is usually half the size or less with no visible difference on screen.
- iPhones record in HEVC by default, which is smaller than H.264 but doesn’t play in every browser.
Will it fit on Dembed?
You can upload files up to 5 GB per video on a free account (around 60–80 minutes of web-exported 1080p) and up to 50 GB with Premium.
Frequently asked questions
Exported for the web, about 3–5 GB. Recorded straight from a phone, quite a bit more (6–8 GB).
