Exporting *pdf causes increase in dimensions

I have business cards with the following sizes

336.42 pixels | 8,9 cm
223.02 pixels | 5,9 cm

After the exporting it to *pdf the size of the pdf is 11,87 × 7,87 cm

How can I fix it?

Hey @Anastasia29, sorry to hear this is happening!

This usually happens when your designs have decimals rather than whole pixels as well as not being positioned on whole pixels.

Can you please ensure your business card designs are and are placed on whole pixels before exporting?
