The height and distance to the throw line can be easily measured when setting up a soft or hard darts board. (The red side is for soft darts and the black side is for hard darts.)
It is very easy to use, and all you have to do is to fasten the darts to the holes A to E that match the position you want to measure at the center of the inverted dartboard. (Soft darts are A, C, and E. Hard darts are B, D, and E.)
Then, measure the height and distance at the position where the bottom of the trapezoidal plate arrived.
When you set up a board at home, you can use a tape measure, but it tends to be off, but with this, you can get the official height and distance exactly, so you can practice practically. (Of course, this is also recommended for bars and amusement centers with professional machines.)
If you have any discrepancies in distance when throwing at home and when throwing on the road, why not use this to re-measure and set up your board?
