Hi, Can you please just let us now what size of postcard you looking for? Do you want a space left on the back of the post card for mailing addresses and postage? Or will this card just be passed out to people and not mailed?
Thank you,
Best Regards
Alex

Hi Alex the size of the postcard is A5 which is 148x210 mm
We will be passing these cards out to people so you will be able to use all of both sides for design. Kind Regards Kerry
