Data Storage Calculator

Photos, videos, and documents pile up faster than most people track, and this tool adds them into one total so you can plan storage before you hit a wall. The squeeze shows up as cloud plans fill and devices run out of room. Knowing the number ahead of time beats scrambling once the warnings start.

The total comes from multiplying how many items you have by a typical file size for each type. Photos are figured at 5 MB apiece, video at 2 GB per hour and documents at 1 MB each. The math uses decimal units (1 GB = 1,000 MB = 1,000,000,000 bytes); a computer that counts in binary gibibytes (1 GiB = 1,073,741,824 bytes) shows the same total about 7% smaller. The result is then matched to the smallest plan in the calculator's list that holds it: a 15 GB free tier, 100 GB, 200 GB or 2 TB.

Treat the result as a working average, since quality and compression push real files well above or below these figures. Your library also grows month over month, so plan for where it will be, not just where it sits today. Adding a buffer of 20-30% gives you headroom for the accumulation you can't predict.
