170 KB gives about 6% more room than 160 KB, so photos come out a little wider (about 1,450–1,850 px instead of 1,400–1,800 px) and sharper. Always pick the biggest size your form or website allows — it gives the best quality.
This mostly happens with PNG files or very detailed pictures. Convert PNG to JPG first, crop the photo, or choose a slightly bigger target.
