About LS Cadencer Tools

These two tools are meant for applying auto-spacing to fonts using an underlying grid for calculating the side-bearings.
This principle and algorithm find their origin in Frank E. Blokland’s PhD research on the (effects of) systematization, standardization, and unitization in Renaissance font production.
The LS Cadencer tools were developed by Lukas Schneider as Extensions/Plugins for the font editors Robofont and Glyphs.

With these tools the principles of spacing, applied in the production of printing types in the sixteenth century, are transferred to our current digital technology of font design.

LS Cadencer is meant for applying auto-spacing to fonts using a grid. This grid is flexible and dependent on the so called stem-interval. The stem-interval is always measured at the key glyph, either the m or the n. The grid can be widened or tightend by the user to influence the spacing in general.

LS Cadenculator, the second tool, reverse engineers what LS Cadencer does. The user can provide a folder of existing font files in .otf or .ufo formats. All side-bearings of a given set of glyphs will be measured in these fonts. The basis of these calculations is again the stem-interval of the ‘m’ or the ‘n’ glyph and the grid-steps which can be influence by the user, to either widening or tightening the underlying grid.

“I tested the tools with some of my fonts and I was very satisfied with the results.”
Nikola Djurek — Typonine

“Using LS Cadencer tools provide a refreshing alternative to my usual work flow. They enable me to work with spacing at the earliest stage of a design, and to use spacing as an integral design element. LS Cadencer's simple spacing system has added the visual rhythm of the classics to my type design toolbox.”

Questions + Answers.

What about Kerning?
The tools do not support kerning yet! It could be that this will be added in the future, but I don't want to put a date on it.
Why are you not offering these tools free?
It took a lot of time to develop, improve and modify the tools.
I think it is fair to charge some money for it in exchange.
Why does LS Cadencer only apply auto-spacing to upper-/ lowercase letters and a few extra glyphs on default?
Expanding the spacing sheets can be done pretty easily by manually adding glyphs or by using LS Cadenculator to measure existing fonts. The great advantage is that spacing tables usually can be reused and applied to a relatively broad range of fonts.

More questions and answers will be added soon.


Lukas Schneider, the developer of these tools, holds a Master Degree in Type Design from the Type & Media program at The Royal Academy of Arts (KABK) in The Hague, the Netherlands. He is also a laureat of the Expert Class Type Design of the Plantin Institute of Typography in Antwerp, Belgium.

I would like to thank Frank E. Blokland for giving deeper insights to his PHD Research and Just van Rossum for introducing me to Python Programming while studying at the Type and Media Department in 2012/2013.

LS Cadencer Tools would not have come to exist without Vanilla by Tal Lemming and Robofab by Erik van Blokland, Just van Rossum and Tal Leming.

Thanks to Frederik Berlaen, Yanone and Georg Seifert.
