Width and Height
Width and height are listed together like this: 500 x 600. The first value is width, the “x” is read as “by,” and the second value is height.
Design software displays the width (W) and height (H) of each layer. Units of measurement vary across design software, but pixels or points are commonly used to measure a layer’s dimensions. For more information, check out about pixels vs. points and Material Design’s resource about pixel density.
