What this tool does
Calculate print scaling for a maker project. Uniform scaling changes all axes; wall thickness and fit clearances also change.
How to use the Print Scaling Calculator
- Enter or select original dimension (mm).
- Enter or select target dimension (mm).
- Read the calculated result; change any measurement to compare alternatives.
Formula
scale %=target/original×100; volume multiplier=(target/original)^3
- original
- Original dimension (mm)
- target
- Target dimension (mm)
Uniform scaling changes all axes; wall thickness and fit clearances also change.
Worked example
For print scaling calculator, the following measurements illustrate the exact method: Original dimension (mm): 100; Target dimension (mm): 75.
Inputs
- Original dimension (mm)100
- Target dimension (mm)75
Result
- Uniform scale (%)75
- Volume multiplier0.42
Results explained
- Uniform scale (%)
- Uniform scale (%) from the formula above. Uniform scaling changes all axes; wall thickness and fit clearances also change.
- Volume multiplier
- Volume multiplier from the formula above. Uniform scaling changes all axes; wall thickness and fit clearances also change.
Frequently asked questions

No. Verify against the machine, tool and material manufacturer's instructions, especially for CNC feeds and speeds.
Measure actual material properties and machine usage, rather than relying on nominal default values.
