…and, Canva defaults the alignment of any new text box to center.

This means, anytime I am designing in Canva, I need to change both settings.

But most people won’t.

The power of a default is that it is the standard for the vast majority of people.

Canva, as a platform, sets what the default is. To change what the default is, you can either petition Canva to change, or become the dominant platform and set your own standard.

What won’t work, is me screaming from the rooftops that every user should use a line height of 1.2 instead.
