The aspect ratio of a geometric shape is the ratio of its sizes in different dimensions. For example, the aspect ratio of a rectangle is the ratio of its longer side to its shorter side – the ratio of width to height, when the rectangle is oriented as a "landscape"
The aspect ratio is expressed as two numbers separated by a colon (x:y). The values x and y do not represent actual widths and heights but, rather, the relationship between width and height. As an example, 8:5, 16:10 and 1.6:1 are three ways of representing the same aspect ratio.
Aspect ratio in the PCB is the hole size for the depth of the drill.
PTH (Plated Through Hole) is calculated as X: Y and is mainly written as 00: 1
In case of LVH (Laser Via Hole), X / Y x 100 = 00% is calculated as% for operator's convenience.
