When should you use this tool?
Use it to choose a sensible layer height for your nozzle and your goal between detail, balanced, functional and fast printing.
Tool · Layer Height
Which Layer Height Should You Use?
A quick starting point based on nozzle diameter and the type of part you want to print.
Starting recommendation0.20 mm
Useful working range0.10–0.28 mm
Rule of thumb, not a hard limit: many profiles work roughly between 25% and 70% of nozzle diameter. Geometry, overhangs, material and the desired surface finish can justify a different choice.

Layer Height Calculator: when and how should you use it?
A useful result starts with the right question. These notes explain what the tool is designed for, how to interpret its output and where a calculation is intentionally only an approximation.
How to use it well
Choose nozzle diameter and priority. Use the recommendation as a starting point, then inspect overhangs, top surfaces, threads and visible curves on the actual model.
Limits & important notes
Nozzle-percentage rules are heuristics. Modern profiles, nozzle geometry, adaptive layers and special models can justify values outside the typical range.
Frequently asked questions
Is a smaller layer height always better-looking?
No. It mainly improves Z-axis resolution. Vertical walls may barely benefit while print time and layer count increase significantly.
Can a 0.4 mm nozzle print 0.30 mm layers?
Often yes when profile, material and geometry allow it. Very tall layers reduce margin for overhangs and can affect surface or interlayer behavior.
What is the benefit of adaptive layer height?
It uses fine layers only where geometry needs them and thicker layers on simpler regions, preserving detail without slowing the entire model.
Is layer height more important than line width for functional parts?
Not in isolation. Layer height, line width, orientation, wall count and material work together to determine speed and mechanical behavior.
These tools provide guidance and calculations from your inputs. Safety-critical, electrical or highly loaded parts require additional verification.
