Letterspacing (?) as a variable in my singleline script

Options
I'm working on single-line script typeface (as far in my own SVG format) for engraving purposes, and i want to use letter-spacing as variable value.

is the name "letterspacing" accurate?

    You could use width since you are changing the widths of the characters, not the space between them (they are touching).
  • If you want to keep it simple use Width like Mark suggests; ideally I might call it Span.

    @Mark Simonson @Hrant H. Papazian  Thank You. Most probably Idea for "Width" as "keep it simple" win :)  It will be hard enough to show CNC-users that a typeface can be variable.

    DJR's latest font, Extendomatic, contains a similar function. In the variable font, the width axis is referred to as "Tracking". Whether that's the most appropriate term is up for debate, but it certainly makes sense to me.

    ... axis is referred to as "Tracking"...
    You're right, "Tracking" could be a good term for it, but from my point of view is too confusing with the slider found in most programs and "bad tracking of scripts".
    btw.  my new test of 2 axes - width (letterspacing) & stroke






  • Call the axis GOODTracking.  :->

    good idea, especially since "bad tracking" will be available all the time in settings :->

    Beautiful work, Grzegorz! 

    I encourage you to use wdth and wght axes for this.

    +1 to using width ('wdth')

    Conceptually, it is a connected script with a width axis. No reason to invent something new.

    One concern I have with a spacing/tracking axis is that it needs to work across the entire design space, and across all the kerning. 

    I'm yet to see any demo font that does this, despite it being talked about since 2016. 

    Has anyone seen such a font?

    @Thomas Phinney  thank You
    @Matthew Smith
    [...]  (especially if you don’t see yourself drawing an axis with narrower or wider base/core letterforms) [...]
    thanks for paying my attention. I will probably want to add such an axis in future and I would have to change axes names  :)

    don't forget about ligatures :)

    LOL

    Since you are planning to add such an axis in future, I retract my proposal. 

    I'm curious what you propose instead of width.

    In the parametric axes system, changes isolated to X and Y dimensions use that as basis of the first letter of the axis code, and then if it's effects ink (opacity) or space (transparency) for the second letter. So I will probably register something "XT??" for this with Google Fonts. XTRK for X Transparency Tracking? XTSP for X Transparency Spacing?

    Right, if there is a significant chance of having both kinds of width axis in the future, def save the one called “width” for the more normal implementation.

    first "quick and dirty" prototype of normal Width axis made me sure that it is worth keeping the name for the future - cooperation of these two axes has potential
    now I like the Span proposal of @Hrant H. Papazian more and more...

    I think its good for users to have separate control of the 'X Transparency' changes within a glyph from the 'X Transparency Spacing' changes between glyphs, instead of blending them. 

    The initial lexend.com fonts by Thomas Jockin did this, with a single LXND axis, and the latest ones at https://github.com/FontBureau/fb-lexend split them out.

    first demo engravings:


    and first pre-release on-line:  www.glukfonts.pl/g/LimpelkaSL
    with Span & Width axes in Variables tab.
    Thank You for all Sugestions!
  • Nice!
    Congrats, and good luck.

    I think I will need a lot of luck with my "TypoGuerilla"   ;)
