What this page covers
1x1 picture size requirements matters because official photo systems are strict about the final artifact, not just the source picture. Use this as a requirements checklist for the selected document or country. The safest workflow is to start with a current, sharp, front-facing photo and then export a file or print that matches the selected authority's requirements.
Core checks
Check the final size, head position, background, expression, lighting, eyewear, headwear, and image quality. Digital workflows also need file type, pixel dimensions, file size, and compression checks. Printed workflows need paper quality, physical scale, and clean cutting.
Common failure pattern
Most rejections come from using a convenient image instead of a compliant identity photo: a social-media portrait, a screenshot, an edited profile photo, a file compressed by a messaging app, or a photo taken too close to a textured wall. When the source has capture problems, retaking is safer than editing.
How Photo Gov app helps
Choose the relevant country or document page, upload the original source image, review the preview checks, and export the clean file only after the crop and output match the selected requirement. Final acceptance still belongs to the issuing authority.
