Not sure what you mean. Do you mean the size or the layout? No to both, I designed the PCBs in KiCad to fit on 7cm x 10cm copper PCBs and then cut them to size and sanded the corners with a rotary tool like a dremel and then transferred the PCB mask with PCB heat transfer paper and an iron (one for clothes) onto the plain copper PCB and etched away the unneeded copper with ferric chloride. Then I drilled the holes using PCB drill bits for my rotary tool and soldered in the components according to the layout.
