1. Rounded Rectangle Vector Tool
Photoshop’s Rounded Rectangle vector tool appears like the ideal
candidate for the task, until you realize that the edges it creates are blurry
and inconsistent.
Fortunately, there is a fairly well-hidden option that locks the Rounded
Rectangle vector tool’s output to the pixel grid. Excellent.
To enable pixel-locked drawing for the Rounded Rectangle vector tool,
check the “Snap to Pixels” option in the Options bar. If you have “Snap to
Pixels” turned off, drawing at 100% zoom achieves the same result.
