Size & Composition
The digital-only 200x200px format is stricter about proportions than a typical print photo.
Unlike many countries that issue a printable 35x45mm or 2x2 inch photo, Saudi Arabia's eVisa system (visitsaudi.com) only accepts a small, fixed 200 x 200 pixel square image, uploaded directly to the online application.
Because the canvas is so small, your face needs to fill 70-80% of it, measured from the bottom of your chin to the top of your head. A photo that works for a US or Schengen visa will almost always be cropped too loosely for Saudi Arabia's system.
Your face should also be centered and facing forward, with no tilt to either side.
