Hello, I'm travelling to Brienz later this month with my wife. We have purchased our travel passes and printed them.
Is it possible for us to print them off at a smaller size ie A5 or do they have to be A4?
Welcome to MySwissAlps! I recommend to stick to what the suppliers recommend, which is A4 or 'Letter' for travelers from North America. The risk of a smaller printout is that the QR-code will also be smaller and I don't know if that can cause scanning issues on the trains. You can fold the paper as long as you don't fold the QR-code, so it will fit in a wallet.
