EDIT 10/07: Community bumped this Q, but I think we should first resolve the issues around closure before proceeding with this.

Following up on Vincent's proposal here I'm starting a list of questions about pixels, pixel density, ppi, dpi, etc. I'm also proposing a canonical Q&A.


I realise this is quite broad, and can be sub-divided in different aspects. I'm open to suggestions from the community about how to handle this. If enough people think this should be divided up into multiple canonicals, I'm not against it.

Additionally, joojaa already attempted to do something similar with this Meta Q, but I think it's better to have a Q&A on the main site to use as a dupe hammer.

    It might be good to list the different aspects since it's pretty broad Commented Jun 9, 2017 at 13:24

    I didn't have time (nor much incentive) to do that, but feel free to have at it ;)

1 Answer 1


Excellent Idea, I think the fact that it's quite broad and one question is useful for a canonical question (It will be easier to keep track of it etc).

It's one (broad) question that covers (almost) all of the above ones, and the answer will be one (maybe one answer for each point) very long answer which will answer all those points.
