We have about zero experience in the graphic arts, so we’re not entirely sure if the above is actually useful to anyone, but we feel like it might. It’s a ruler that measures in pixels. We think that’s pretty nifty, except we’re not too sure how it works. Don’t different screens have different size pixels? Here’s the description the manufacturer gives:
The ultimate tool for responsive screen size sketching. Heavy-duty gauge stainless steel ruler with pixel increments. Markers for mobile, tablet and widescreen (laptop) sizing.
So it says its got a 150ppi scale… Oh. Right, ok, so that means that if your screen is of another density than 150ppi, you can adjust accordingly, right? Or this only works with 150ppi screens? We get that it’s meant so that what you draw on paper will have the same size on screen, we’re just lost with the scales…
