The square Alexa Built-in sticker is for use on the palm rest of a certified Alexa Built-in Windows 10 PC. All other marketing placements should use the Alexa Built-in rectangular badge, if the product qualifies as Alexa Built-in.
Clear space is the area around the sticker that should remain free of any other logos, graphics, text, or borders. While more is better, the minimum clear space for the logo should be equivalent to half the height of the Alexa icon.
The Alexa Built-in sticker can be larger, but the minimum size is 18mm x 18mm.
