Compute the scaling
Enter the original dimensions (width, height, depth) and the target width: the tool gives the scale factor and the new dimensions.
Example
| Input | Value |
|---|---|
| Original | 50 × 30 × 20 mm |
| Target (width) | 75 mm |
| Factor | 150% |
| New dims | 75 × 45 × 30 mm |
Uniform scaling, 100% local calculation.
Frequently asked questions
How is the factor computed?
Target width ÷ original width × 100. The same percentage applies to all three axes.
Does the model stay proportional?
Yes: scaling is uniform, proportions are preserved.
Where to enter the percentage?
In the “Scale” field of your slicer, or directly in your modelling software.
