10–400% of the original. 50% halves both sides.

FAQ

How do I reduce file size?

Resize the width to 1200–1600px and save as JPG at quality ~80; most photos end up under 500KB. WebP is smaller for the web.

Does enlarging lose quality?

Yes — upscaling beyond the original blurs. Use the largest original you have.

Instagram or YouTube sizes?

Use the Social Image Resizer presets.
