Postcards are usually 13 x 18 and 8 x 13 cm. All sizes of Ellty templates are already the correct size, so you don't have to worry about sizes.
Your postcard should be in PNG, JPG or PDF format at the highest resolution for the best display quality. If you are creating a postcard for printing - download it in PDF format to send it to print.
Why do you need a postcard
