We're working on a site that requires the user to login to use. We designed a sparse login page with a large login form. Akin to Gmail:
This seems to be the trend as of late. And it makes sense for a lot of reasons.
- clear focus on tasks
- easy targets to hit/interact with
- ideal for mobile
It's been brought up that the rest of the forms we use on the site don't necessarily follow this 'large field' style that the login form has.
I think this is fine, it's perfectly valid to have different patterns for different forms, and I think the reasons above are more than enough to justify it, but like many projects we deal with, we inevitably get asked to show research to justify it. (I know, 'ugh')
So, I ask: Does anyone know of any usability testing research that shows there are valid reasons for the 'large login' pattern other than it being purely subjective preferences?
