Re: Testing 1.4.4 Resize and 1.4.10 Reflow

For SC 1.4.10, the resolution is not "defined as 1280 and 1024". It is defined as either 1280 CSS pixels wide or 1024 CSS pixels high at 400% zoom, depending on whether the content is designed to scroll vertically or horizontally. The other dimension is not specified in either case.

I don't think that testing SC 1.4.10 at 100% zoom in a 320px wide window is valid because the Understanding page refers to "the goal of allowing people to zoom in to 400%." And there are numerous other references to 400% zoom.

The issue of the scale percentage (in system display settings) is interesting because I have not seen that discussed previously, yet it is relevant to many people who work on laptops. All my machines are set to 100% so it's not an issue for me, but I am aware that 125% or 150% are common default settings for physically small displays with high resolution. My view is that they must be set to 100% for testing purposes.
