Your lie angle is the angle between the centre of the shaft and the sole of the club, and it’s important as it can affect how your club enters the turf at impact, and consequently, which direction the ball travels in.
A perfect lie angle, commonly referred to as square, is when the sole of your club is parallel with the turf.
To find out your current lie angle, most professionals and fitters use a couple of methods; a static fitting and a dynamic fitting.
A static fitting relies on data you provide, such as your height, and it helps your fitter assess the suitability of the current lie angle at address.
The dynamic fitting then takes place when you hit a few shots on a lie board, as shown below. As your club hits the board at impact, it will make a mark – either on the sole or on the lie tape stuck on the sole. This mark then highlights your current swing plane.
