How Do I Use the Scale Command in AutoCAD?

AutoCAD is a powerful software used for creating precise and detailed 2D and 3D designs. One of the fundamental commands in AutoCAD is the Scale command, which allows you to resize objects accurately. In this tutorial, we will explore how to use the Scale command effectively to transform your designs.

Understanding the Scale Command

The Scale command in AutoCAD enables you to resize objects uniformly or differentially. It allows you to scale objects up or down while maintaining their proportions. This command is particularly useful when you need to adjust the size of multiple objects simultaneously.

Using the Scale Command

To use the Scale command, follow these simple steps:

  1. Select the objects that you want to scale.
  2. Access the Modify panel located on the Ribbon.
  3. In the Modify panel, click on the Scale button.
  4. A dialog box will appear with various options for scaling.
  5. Type ‘S’ for Uniform scaling or ‘D’ for Differential scaling, followed by Enter.
  6. If you chose Uniform scaling:
    • Select a base point from which your selected objects will be scaled.
    • Type a scale factor or specify a reference length and new length.
    • Type, ‘All’, ‘Base’, or ‘Reference’ depending on your preference.
    • Select additional objects if desired and press Enter.
  7. If you chose Differential scaling:
    • Select the object(s) that you want to scale differentially.
    • Select a base point from which your selected objects will be scaled.
  8. Your objects will be scaled according to the specified parameters.

Tips for Using the Scale Command Effectively

Here are some additional tips to help you make the most out of the Scale command:

  • Before using the Scale command, it is advisable to make a copy of your objects. This way, you can easily revert back to the original size if needed.
  • If you want to scale an object by a specific factor, type in the scale factor directly. For example, typing ‘2’ will double the size of the object, while typing ‘0.5’ will reduce it by half.
  • To scale an object using a reference length and new length, select two points on your object that represent these lengths.

    AutoCAD will automatically calculate and apply the scaling factor based on these measurements.

  • The ‘All’, ‘Base’, and ‘Reference’ options in the Scale command give you more control over how your objects are scaled. Experiment with these options to find what works best for your design.
  • If you have multiple objects that need scaling, use a windows selection. Simply click and drag to select all the objects within the desired area, and then proceed with the Scale command.


Mastering the Scale command in AutoCAD is essential for resizing objects accurately in your designs. By following the steps outlined in this tutorial, you can easily scale your objects while maintaining their proportions.

Remember to experiment with different scaling options and utilize the tips provided for optimal results. With practice, you’ll be able to effectively use the Scale command to transform your designs and bring them to life.
