How to set up the values for three axis variable font. How many masters?

One-glyph file, changing the shape to fit the page-size. Wider-taller — dimension One.
The Two is the vertical centerline in the shape — it moves left-right. The Three is movement of horizontal one to the up and down.
Six masters for all of them is enough, isn’t it?

Minimum number of masters = number of axis plus one. So four in your case:

B
|   C
|  /
| /
|/
A--------D

Any extra masters must be in a rectangular arrangement with the masters, so maximum 8 masters:

    E--------H
   /|       /|
  / |      / |
 /  |     /  |
B---|----F   |
|   C--------G
|  /     |  /
| /      | /
|/       |/
A--------D

Only add the masters you need. Test first if it works without, only add if necessary. If only a few glyphs need it, consider a Virtual Master. See the Variable Font tutorial for details.

Thank You! Rainer! (Still impressed by Your Talk in Paratype))
Yes, I’ve seen the tutorials and these schemes too!
But I’m confused))) What the numbers do I have to put. And I still do not understand how it could work if none of four masters contain the all points I need. I attach the pic there is the all points I need, and each of them I set as a master.

3 axes? 7 masters.
Then the magic cube happens… 7 masters if the default is amidst the three axes, that is the power and Ui of variables?

Use Design space to interpolate to the middle instance 0f your 3 axes, make that 7th master the default, make the other 6 the extremes of 3 axes.

Cube.

6 masters is for when one axis is 1/2 an axis,

Meekkablue: why do you want want the middle of the design space to be found with sliders, instead of being the default?

So not


but rather

Both strategies are possible, both have advantages and disadvantages. I discussed them in the Variable Font tutorial.
