ohhhh! then you're not doing it right ;-) ie. the grip on the second image (your hand) is NOT the same as the grip on the top image.
bevel 5 is sitting on different places of the hand... so just close that gap...
Important to remember that grips will look different in hands of different sizes. Especially with differences in hand
proportions (that is, the length of the fingers compared to the size of the palm). Also, a very meaty (or fat) paw will grip the racket somewhat differently from a very lean or svelte hand
What looks and
feels comfortable and what works for one hand, might not necessarily work for someone with a very different hand shape / proportion
Note in the first image that there is quite a gap between the tip of the middle finger and the rest of the hand. Perhaps more than a finger's width of gap. In the 2nd image, the tip of the middle finger is nearly touching the opposite side of the hand around the grip. To make the second image look more like the first, the OP would probably need to use a racket with a larger handle circumference
Note also that there are many elite players who use a variation of the standard SW grip. Some do not have the base index knuckle squarely on bevel 4. It might shade toward the Eastern in some cases. Or, in Novak's case, the base index knuckle is closer to level five than the standard SW
Also, not everyone has the heel pad on exactly the same bevel as the base index knuckle. It will often vary by a half bevel (one way or the other). In some cases, as seen in the link at the bottom of this post, it may vary by up to a full level
The standard description has both of the primary reference (knuckle) and the secondary reference (heel pad) on the same bevel. But this is not always the case. I recall when I was studying the document ation for USPTA certification nearly 20 years ago, they were promoting something different. The heel pad was offset by a half bevel or more for many, if not all, of the grips. This was different from the grip instructions I had learned in the 90s
However, it appears that the USPTA has now gone back to the simpler, standard grip descriptions. Here is another source from 8 years ago, that shows something different from the simple, standard grip descriptions
If you are a tennis beginner, we begin our lessons with the tennis grips. There are four basic grips in tennis: Eastern Grip, Continental Grip, and Western Grip
