About 3D Model Scaling

The 3D Model Scaler resizes GLB models with precision for any application. Whether you need to scale models for 3D printing, adjust dimensions for AR visualization, or resize assets for game development, this tool provides accurate scaling with unit conversion support including millimeters, centimeters, meters, inches, and feet.

Our scaler maintains model proportions and quality while adjusting dimensions. Scale uniformly to preserve aspect ratios or scale individual axes for custom dimensions. Perfect for preparing models for 3D printing at specific sizes, adjusting architectural models to real-world scale, or resizing game assets to match your project requirements.

How to Scale 3D Models

  1. 1Upload your GLB file to the scaler. The tool displays current model dimensions and allows you to choose your preferred measurement units.
  2. 2Enter your desired dimensions or scale factor. Choose uniform scaling to maintain proportions or scale individual X, Y, Z axes independently for custom shapes.
  3. 3Preview the scaled model in real-time with the 3D viewer. Verify dimensions are correct before downloading. The tool shows both original and new sizes for comparison.
  4. 4Download your scaled GLB file with precise dimensions. The model is ready for 3D printing, AR applications, or any other use with exact measurements.

💡 Tip: For 3D printing, scale to your printer's build volume. For AR, scale to real-world dimensions. Use uniform scaling to maintain model proportions.

Common Use Cases

3D Printing Preparation

Scale models to fit your 3D printer's build volume. Adjust dimensions precisely for miniatures, prototypes, or full-size prints with accurate measurements.

AR Visualization

Resize models to real-world scale for augmented reality. Ensure furniture, products, or architectural elements appear at correct sizes in AR apps.

Game Development

Scale assets to match your game's unit system. Resize characters, props, and environments to maintain consistent proportions across your project.

Architectural Models

Adjust building models to accurate real-world scale. Convert between different unit systems for international projects and precise visualization.

Frequently Asked Questions

Find answers to common questions about this tool.

Scaling 3D models is essential for 3D printing, manufacturing, game development, and architectural visualization. You might need to resize models to fit specific dimensions, prepare them for different output devices, or adjust them for real-world applications where precise measurements matter.
Use this tool when preparing models for 3D printing at specific sizes, creating miniatures or large-scale replicas, adjusting models for game engines with different unit systems, or when you need precise dimensional control for manufacturing, prototyping, or architectural projects.
Our tool offers two scaling methods: Multiplier scaling (scale by a factor like 2x or 0.5x) and Dimensional scaling (set exact measurements in centimeters or inches). Both methods support uniform scaling or independent axis scaling for maximum flexibility.
When 'Lock Aspect Ratio' is enabled, changing one dimension automatically adjusts the others proportionally, maintaining the model's original shape. Disable it if you need to stretch or compress the model along specific axes, though this may distort the appearance.
Our scaling tool supports GLB, GLTF, OBJ, STL, PLY, and USDZ formats. The scaled model is output in the same format as the input, preserving all materials, textures, and other properties while applying the new dimensions.
Simply click 'Select File' or drag and drop your file into the upload area. The conversion will start automatically and you'll be able to download the converted file once it's complete.
You can upload files up to 100MB in size. For most 3D models, this is more than sufficient. If you need to process larger files, please contact us for assistance.
Our conversion tools are designed to preserve quality as much as possible. However, some formats may have different capabilities. We use industry-standard algorithms to ensure minimal quality loss during conversion.
Processing time depends on file size and complexity. Most files are converted within 30 seconds to 2 minutes. Larger or more complex models may take longer.
Yes! This tool is completely free to use with no hidden fees, subscriptions, or limitations. You can convert as many files as you need without any cost.
Absolutely. We take privacy seriously. Your uploaded files are processed securely and automatically deleted from our servers after conversion. We never store or share your files.
