This calculator helps you estimate filesize, using bandwidth and time as inputs. Use it to estimate video file size, disk size, network backup capacity...

Calculate file size

1 minute * 73 Mbps

= 1 minutes * 9.13 MB/s

= 547.5 MB

    • Frequently Asked Questions

    How do I calculate file size from bandwidth and time?

    Multiply bandwidth by time: Size = Bandwidth × Time. Convert units first: 100 Mbps × 60 seconds = 6000 Megabits = 750 MB. Remember: 8 bits = 1 byte, so divide bits by 8 to get bytes.

    How big is a 1-hour video file?

    Depends on bitrate: YouTube HD (5 Mbps) = 2.25 GB/hour. Netflix HD (5.8 Mbps) = 2.6 GB/hour. 4K streaming (15-25 Mbps) = 7-11 GB/hour. Blu-ray quality (40 Mbps) = 18 GB/hour.

    What is the difference between MB and MiB?

    MB (megabyte) = 1,000,000 bytes (decimal, SI standard). MiB (mebibyte) = 1,048,576 bytes (binary, 2^20). Hard drives use MB; Windows often shows MiB. A "1 TB" drive shows as 931 GiB in Windows.

    How many hours of video fit on a hard drive?

    At Netflix HD quality (2.6 GB/hr): 1TB = 385 hours. At 4K (10 GB/hr): 1TB = 100 hours. At Blu-ray quality (18 GB/hr): 1TB = 55 hours. Compressed formats like H.265 can nearly double these numbers.
