Outside the EU, Same Standard
Switzerland is not an EU member but uses the 35x45mm ICAO photo.
Switzerland sits outside the European Union while being part of the Schengen Area, and it uses the same 35x45mm ICAO photo format as its EU neighbours for passports and identity cards.
Practically that means a photo cropped for a German, French or Italian document is the right shape for a Swiss one — which is convenient given how many Swiss residents hold documents in more than one country.
