Hi bundabrg, Please see: https://easyeda.com/Doc/Tutorial/PCBOrder.htm for details of EasyEDA's PCB fabrication capabilities. :)

EasyEDA's PCB order system can support 50cm * 50cm, But EasyEDA's editor hasn't limit. And we are sure we can find some PCB houses to fab. the size more than 50cm. So you just need to focus the design, we will help you in the fab. BTW, in the order help file, we set the size `30cm x 30cm`, because we just have boxs in that size for shipping. We will change this to `50cm*50cm` soon. Thanks.

Thanks both. Missed the 30x30 on the PCBOrder page and the updated 50x50 is useful to know.
