Bringing population‑aware physics into apparel sizing and grading.

Nabla Labs builds upstream fit infrastructure for apparel brands and manufacturers. Our engine ingests existing CAD/DXF graded patterns, simulates them across diverse body distributions, identifies where grading produces inconsistent fit, and returns corrected pattern geometry alongside a clear diagnostic. The work happens before production: before fit samples are sewn, before factories cut fabric, before customers experience the inconsistency at retail.

We extend the work that traditional fit-standards methodology pioneered. Our engine is calibrated against established body‑standard practice and works alongside the 2D and 3D CAD tools brands already use. We see ourselves as a layer in the stack, not a replacement for the experienced pattern makers, technical designers, and fit professionals who define brand fit identity, but a tool that gives those people more precise data and faster iteration.
