USE PERCENTAGE VALUES
Any settings we make are recorded in an Action, so we need to be aware that if we set an amount in pixels, then the results may vary depending on the resolution of the image. If an image is 500 pixels wide then adding a 50 pixel border will look very different compared to the same value border on a 5000 pixel wide image. As such, it ’s often better to use percentage values if you can. Simply add a percentage symbol after the amount to change the units.
