If you have enabled certain print sizes but they are not showing up in the Fotomoto cart when you click 'Buy Print', this is probably because you have either a) not enabled the correct print sizes or b) not selected the appropriate Print Size Option.
First please read about our Print Size Options to learn how they work and which print sizes to enable. If you need help or have any questions about the best setup for your needs feel free to contact us - we're happy to help.
