Gelato supports several standard formats designed both the North American market (US and Canada) and for the rest of the world. At the same time, thanks to our network, we are able to offer some North American formats in the rest of the world and vice-versa.
If a product appears unsupported in a specific country, it might simply be because of the paper specifications you choose. E.g. An A4 flyer is available both in North America as 60lb text paper and in the rest of the world as 90gsm. Please refer to this article for paper equivalence.
