For the named family, start with Jonatan Xavier’s project
Xavier’s original Split family showcase describes a geometric, square-sans construction with rounded corners and stencil inspiration. It lists Outline, Filled and Doodle treatments. The December 2017 project account links to its commercial resource; a free-font tag by itself is not a full license statement. Keep the creator’s name beside the family when distinguishing similarly named downloads.
For the film titles, read the actual design-team interview
In Filmograph’s first-person interview about Split, creative director Aaron Becker explicitly names Helvetica. He discusses large lettering, unusual alignment and connecting forms; producer Seth Kleinberg describes the repeated grid treatment. These decisions concern a complete title composition, not a font called Split that automatically generates the sequence. The two projects should not share an attribution merely because their names match.
Compare a stencil treatment and a divided composition separately
For a new studio poster, set an invented name with Outline and Filled alternatives where those original resources are available. Inspect the smallest gaps at actual output size before adding a second border. Separately, build a plain sans title in an original grid and compare one repeated arrangement with one interrupted arrangement. Judge whether the entire name remains discoverable without requiring the viewer to reconstruct every letter. Stardos Stencil and Inter are independent comparisons for those two exercises. The homepage copy-and-paste text styles use Unicode substitutions; they do not supply either original family or the film’s animation.
Your questions, answered.
Did the Split film titles use Jonatan Xavier’s Split family?
The film’s design-team interview names Helvetica. Xavier’s separately documented Split family is a different project.
What styles does Xavier’s family account list?
The creator lists Outline, Filled and Doodle. Use the original resource to inspect their actual forms and package terms.
