Video and screen recording size calculator
See how much space a video or screen recording will take before you record.
Estimated size

Based on typical phone camera bitrates. A mostly still screen recording is often smaller, and games and fast motion are often larger.
How the estimate works
Video size depends on bitrate, which is how much data the phone saves each second. The tool uses typical bitrates for common quality settings and multiplies by your recording length. Real files vary with what is on screen, since busy scenes and fast motion use more data than a still screen.
A screen recording of a mostly still screen is often smaller than the estimate. A game or a camera video at high frame rates is often larger.
Save space on long recordings
Record at 1080p instead of 4K unless you need the detail. Use 30 frames per second instead of 60 for tutorials. Trim the start and end of each clip and delete the original after you share it.
Frequently asked questions
How big is one minute of 4K video?
Roughly 170 to 400 MB depending on the frame rate and the phone's compression, so a few minutes can fill several gigabytes.
How much space does a screen recording take?
Often 20 to 100 MB per minute at 1080p, and more for games and fast motion. Use the calculator for a rough number.
