What sizes are acceptable for postcards?

Good day.

I usually ship 148x105mm or 14.3cm x 9.3cm.
What sizes are acceptable for postcards?

I’m from Malaysia and the postal service here used these measurements as the guideline. Your postcard is exactly A6 size if I’m not mistaken, which is a very common postcard size, so it should be acceptable.


I once sent an A4 sized 3D postcard, but did use an envelope. :sweat_smile:



Omg that’s really cool! I rarely get to see any A4 sized postcards here, maybe it’s because postcards aren’t easy to find everywhere, only in major cities or tourist destinations you can find them. Yeah if it is sent in an envelope, it is alright.
