At least 2 × 2 cm (about 0.8 in) for something held in the hand, like a business card. For posters, a common rule is about one tenth of the scanning distance: a code scanned from 2 m away should be about 20 cm wide. Use SVG or PDF for print so it stays sharp at any size.

Yes. Keep the code dark on a light background with strong contrast: light codes on dark backgrounds, or pale colours, can fail on some phones. Always test the downloaded file with your phone before printing.
