3D Print Layer Resolution Calculator

Finds the ideal layer height for your 3D print given your nozzle size and stepper resolution. Use it before slicing to balance print quality against build time.

0.2-0.32 mm is the standard range, about 50-80% of nozzle width. The example's 0.3 mm sits here β€” a balanced speed/quality choice that stays under the 80% extrusion ceiling.

Layer height is expressed as a fraction of nozzle diameter; the industry rule keeps layers between 25% and 80% of nozzle width, so a 0.4mm nozzle at 0.75 quality gives 0.3mm (example).
