I've never used Canva. But are you saying it only has the US business card size? Because Canva is an Australian company, and Australia's business card size is different from the US. It seems weird that an Australian company would support the US standard for something but not the Australian one???
There isn't a single European business card size, there are three different standards [0] – Western Europe (except for Scandinavia) is mainly 85 mm x 55 mm, Scandinavia is 90 mm x 55 mm (which is also used in Australia and New Zealand), while most of Eastern Europe is 90 mm x 50 mm – all three are different from the US/Canada standard size of 88.9 mm x 50.8 mm, although the Eastern European size gets pretty close (1.1mm wider and 0.8mm shorter).
Yup it only has US template, and it’s impossible to print “business cards” if not using a business card template. Without going through support that is.
