3D Model Scaling Calculator
Calculate scaling ratios and dimensions for resizing 3D models accurately
About this calculator
The 3D Model Scaling Calculator helps you accurately resize 3D models by calculating precise scaling ratios and dimensions. Whether you're working with CAD files, STL models for 3D printing, or game assets, this tool ensures your scaled models maintain proper proportions and fit your exact requirements. It's essential for 3D designers, engineers, and hobbyists who need to resize models for different applications, from miniatures to architectural prototypes, while preserving dimensional accuracy and avoiding distortion.
How to use
Enter your original model dimensions (length, width, height) and specify either your desired new dimensions or scaling ratio. The calculator will automatically compute the corresponding values and show you the exact scaling factor needed. Apply these results to your 3D modeling software or slicer settings for accurate resizing.
Frequently asked questions
What's the difference between uniform and non-uniform scaling?
Uniform scaling maintains proportions by applying the same ratio to all dimensions, while non-uniform scaling allows different ratios for each axis, potentially distorting the model's shape.
Can I use this calculator for 3D printing scale adjustments?
Yes, this calculator is perfect for 3D printing. Enter your model's current size and desired print size to get the exact scaling percentage for your slicer software.
How do I maintain aspect ratio when scaling?
Use uniform scaling by applying the same scaling factor to all three dimensions (X, Y, Z). This preserves the original proportions and prevents distortion of your 3D model.
