There is a lot of information about the importance of swing width, and I don’t think any good instructor would argue the value of sufficient width in the golf swing. But many golfers struggle with the concept, because they don’t fully understand what swing width means.
Let’s define swing width in simple terms — it’s the distance the golf club travels away from the golf ball. Here’s an image that may help: Let’s say the player faces 12 o’clock. The club travels a certain width from 3 to 9 o’clock, and another width from 12 to 6 o’clock. The video below explains the concept in more detail.
Swing width greatly varies from player to player, and has two functions: It can create speed, but most importantly, it determines the bottom of the swing arc.
Swings that are too wide (think of a U shape) stay along the ground too long and can bottom out behind the ball. Swings that are too narrow (think of a V shape) get in and out of the ground more quickly and can bottom out too late, or too far in front of the golf ball.
