WCAG 2.5.5 Target size - with different screen resolutions

So I did a little bit of reading up on the CSS pixels compared to the actual pixels, and DPR (Digital Pixel Ratio). I think for most computers it would be OK, but for mobile phones, its DPR can be up to 3 times the amount of pixels. So I would need to do 132 x 132 pixels in storyline for that (at least the target area - it is OK for the button to be smaller, but the target area needs to be bigger - so a transparent square etc. over the button would work.)

I then used the dev tools in chrome to be able to look at the different mobile phone options and see what CSS pixels it would give me. In this example you can see for a Google Pixel 7, the next button I have is actually a bit too small (I think this was 70 x 70 actual pixels in Storyline), so something I need to keep testing. 

A check with an iPad and I'm almost there with this one!

It's good that Storyline are looking into this with fixing screen sizes.

Thanks again for the comments 😁
