Key answer
Height is only one input; base geometry, taper, pitch, density, footprint, backing and formula mechanics must be reviewed together.
Geometry and mechanics
A slender profile may sharpen the tip but reduce robustness. A wider base may improve handling while changing dissolution and material demand.
Application area
Under-eye, forehead and localized spot applications create different contour, backing and handling needs.
Manufacturing tolerances
Prototype drawings should define critical dimensions, inspection approach and allowed variation before custom tooling is released.
