Where the numbers come from
- The authority's own website, notice or form instructions.
- An embassy, consulate or the authority's appointed visa centre, when the authority itself publishes nothing.
- The portal's own upload screen, for pixel and file-size limits.
When sources disagree
We show the stricter rule and explain the difference in a "Good to know" note on the page. Where an authority publishes no value (for example no pixel size), we say so, and say which value VisaSize uses and why.
Checked dates
Each page shows the date its sources were last checked. When a rule changes, the page changes: every size on the site is read from one spec file per document, so a correction reaches every page at once.
Our limits
Photos are made to the published specification. The authority makes the final decision, and an officer can still ask for another photo. Spotted a change? Email hello@visasize.com.
