How Do You Scale Dimensions in AutoCAD?

AutoCAD is a powerful software widely used by architects, engineers, and designers to create precise drawings. When working on complex projects, it often becomes necessary to scale dimensions to fit a specific size or proportion.

In this tutorial, we will explore how you can scale dimensions in AutoCAD effectively.

Understanding Scale Factor

Before we dive into the process of scaling dimensions, it’s important to understand the concept of scale factor. Scale factor refers to the ratio between the original size and the scaled size.

For instance, if you want to reduce an object’s size by half, the scale factor would be 0.5. On the other hand, if you want to double its size, the scale factor would be 2.

Scaling Dimensions Using AutoCAD

To scale dimensions in AutoCAD, follow these simple steps:

  1. Select the dimension(s) you want to scale by clicking on them.
  2. Right-click and choose “Scale” from the context menu.
  3. Specify a base point for scaling by clicking on a reference point or typing its coordinates.
  4. Enter the desired scale factor in the command line or pick two points to define a reference length.
  5. Press Enter or right-click and select “Exit” once you have entered the desired scaling parameters.

It’s worth mentioning that when scaling dimensions in AutoCAD, you have two options: uniform scaling and non-uniform scaling.

Uniform Scaling

Uniform scaling ensures that all dimensions are scaled equally in all directions. This means that if you reduce an object’s size by half, both the length and width will be scaled down by the same factor.

Non-Uniform Scaling

Non-uniform scaling allows you to scale dimensions differently in different directions. For example, you can increase an object’s length by 1.5 times while keeping its width unchanged.

This can be useful when dealing with irregular shapes or when you need to stretch or compress objects in specific directions.

To perform non-uniform scaling in AutoCAD, follow these steps:

  1. Select the dimension(s) you want to scale.
  2. Specify a base point for scaling.
  3. Type “non” (without quotes) in the command line and press Enter.
  4. Enter the desired scale factor for each axis separately.


Scaling dimensions in AutoCAD is a fundamental skill that allows you to adapt your drawings to different sizes and proportions. By understanding the concept of scale factor and utilizing AutoCAD’s scaling tools effectively, you can ensure that your designs are accurate and visually appealing.

Experiment with both uniform and non-uniform scaling techniques to achieve your desired results.


  • Select the dimensions you want to scale carefully.
  • Specify a suitable base point for scaling.
  • Enter the correct scale factor or reference length for accurate scaling.

With these tips in mind, go ahead and confidently scale dimensions in AutoCAD like a pro!
