We are currently using a font size of 12px in Web Access. This is tiny compared to most other things. E.g. the default size in web browsers is 16px, and the default size in Windows and GNOME is 11pt, which equates to 14.666...px.
This is especially noticeable to my eyes in the JavaScript fallback error dialog. It seems browsers give monospace text an even smaller font by default. The text in this dialog look really tiny.
Some reference numbers: macOS UI: 12px Classical Windows UI: 12px Modern Windows UI: 13px Linux UI: 14px Browsers default size: 16px (13.333px/10pt for input elements) VMware Horizon: 15px-17px for login page, UI unknown Google search: 14px (16px for search field) Google drive: 13px Google calendar: 14px vSphere: Login 14px, UI 13px Bugzilla: 13px Swedbank login: 16px Firefox settings: 15px Slack: 15px Wikipedia: 14px Aftonbladet: 16px CNN: 16px
There is apparently a lot of variance between different applications. There appears to be a slight trend of increasing font sizes, though. The most common size seems to be 14px, so that would be the safe choice. Choosing 15px could be more future-proof, though, if the trend continues. And we would still not be terribly odd, as popular applications such as Firefox and Slack use that size.
Font sizes are now adjusted, and I think it looks good. Things also still fit well on a small device.
I also think it looks good overall. Checked that the new font size is used everywhere I could think of. Used inspector tool on login page, redirect page, disconnected page and clipboard field. However, the larger font increased the impression that the footer text, with Version and Copyright, is equally important as the other content. This is especially noticeable on the disconnected page. I think it would look better if the footer text had a smaller font. Reopening for discussion.
The font size of the footer is now reduced to 80% of the normal font size. This is also roughly what we had in the mock-ups. We discussed also making the text colour lighter, but that reduces contrast and hence legibility, so let's see if we can make do without it.
I think it looks much better now with the smaller font size. Checked login page, redirect page and disconnect page.
