About Social Video Size
Each platform profile maps to a recommended pixel size and its numeric aspect ratio, with an orientation hint for best crop. Posting the wrong dimensions gets videos cropped or letterboxed, so matching each feed's proportions keeps the frame intact.

- In particular, this calculator does not take inflation, tax, fees or charges or compounding frequency into account.
- Figures are rounded for display to 3 decimal places, so totals built from several rounded parts can differ slightly from the unrounded arithmetic.
