I also like how all this stuff goes out of the window…

Hello!

I apologise if I came across as aggressive: I didn’t mean to, this was a quick “type and hit go” post. I understand your reasoning with this subject - making sure documents are readable for children is an important thing, and I understand that documents are reused from year to year, so the same fonts will be used. All I’m saying is that there are plenty of free specialised alternatives now (compared to 10 years ago, especially), which when the documents/worksheets come up for renewal or updating, should be considered. 

The site I linked to interestingly recommends Arial as an option as well, although I’d say that’s the best of what is out there that comes with PCs normally. Personally, I’d look for things like combinations of oa, oe, bd and see if they look confusing. Comic Sans has a slight difference between “b” and “d” (one of the slopes is slanted) and the letters are fairly widely spaced and I feel that is part of the increased readability.
