Planning assumptions

Whole number, 0–1,000,000,000.

Per photo, in the unit below. 0.000001–1,000,000.

Choose the unit used for your average.

Whole number, 1–100. Include the original if it is one planned copy.

0–100%. Leave blank for 0%. This is an assumption, not measured overhead.

Your storage plan

Enter your assumptions to calculate.

GB is decimal; GiB is binary. Results display up to 6 decimal places. Tiny nonzero values use scientific notation. The total planning ceiling is 1 PB.

Method, sources and limits

One copy = photo count × average size. All copies = one copy × total copies. Optional headroom multiplies each by (1 + percent ÷ 100).

Logical size is not allocated disk space. Include metadata, edits, videos and other files in your estimate if needed. This tool cannot verify independent backups, successful copying or recovery.
