In my browser I currently see it scaled down to 241x42 pixels.
Here is a sample PNG version scaled down to that size, with #1a1a1a background, 1468 bytes.
Can you get the dimentions in pixels of the scaled image on 4k display in full screen mode?
Right-click the image, select ‘Inspect’, devtools window will open, there will be colored boxes with dimensions.
(Article describes how to do it in Chrome The Box Model in DevTools | Codecademy , almost the same for Firefox).
this is the same as what you wrote in the OP, it seems to be more like logical pixels as a unit and not actual pixels.
I think we should just follow discourse’s recommendation of 600 x 80 px.
