Hi,
Thank you to resolve #63759, now here is the sequel.
In edit mode, Bevel Tool -> Vertex Only : when I enter a width value, it is wrong on the plane or the cube with the width/depth type (see images below).
It's OK with the offset type.
In addition, on the vertex's bevel of a cube, it's more difficult because I don't know where is the right width or the good depth, it's easier on a edge.
You can see we find the same wrong values on the plane and the cube.

@Gvgeo-1 do you want to take a look at this too?

Of course, it is my mistake.
I had exactly this problem at some point.
I thought I solve it. I did measure the cube A LOT.
But at some point managed to break it?
I don't remember now, what it was. But will try to find it again.

Hi,
Very good job, Offset and Depth work fine.
But I'm sorry, I still have a error with the Widht Type.
Changed status from 'Open' to: 'Resolved'
My bad, I saw you didn't guess the cryptic way of calculating width.
But till I find and fix the problem, I forgot to explain.
I'm not sure, what the last shape is. So I used your first one. Easier to point out.
The center axis(used by depth) is calculated from the edges, and not the vertex normal(sometimes gives problems).
Not a perfect solution, but works.
It is too difficult to calculate the width, the way you expected.
I'm closing the bug. But if you find that the value is wrong, feel free to open it again.
If your need, clearer picture. I 'll be able to make a blend file later.
And thanks for not leaving it. It could easily be wrong for a long time, before some notice it.
OK, I understand your calculation, even if I do not completely agree with it: I understand it is difficult to calculate and I'm not a developer ;-).
The Widht value is equal to the diameter of a circle whose center is the orthocenter of the triangle formed by the edges.
It will have to be explained in the documentation.
And if we increase the number of segments, it changes the whole topology of the corner. It's getting harder and harder to find a good bevel value.
It's really not easy for a bevel on a Vertex Only.
