Place 0 line on scale (left) on the starting point of length and place mouse-pointer on scale on ending point of the length. The reading that shows in white on scale is the measured length in pixel.
The usual position of the ruler is horizontal. If you want to measure vertically, click the curved arrow on left of the scale, it will take position vertically and vice versa.
