How Do I Scale a Plan in SketchUp?

Are you working on a project in SketchUp and need to scale your plan? Scaling is an essential skill that allows you to resize your model accurately.

In this tutorial, we will guide you step-by-step on how to scale a plan in SketchUp. Let’s get started!

Step 1: Import Your Plan

The first step is to import your plan into SketchUp. To do this, go to File > Import.

Select the file containing your plan and click Open. SketchUp supports various file formats, including JPEG, PNG, PDF, and DWG.

Step 2: Set the Scale Tool

Once your plan is imported, go to the Tools menu and select Tape Measure Tool. Alternatively, you can use the keyboard shortcut “T” to activate the tool. This tool allows you to measure distances accurately.

Step 3: Measure a Known Length

Select a known length on your plan that you can use as a reference for scaling. For example, if you know the width of a door or window opening, measure it with the Tape Measure Tool. Click on one end of the length and drag the measurement line to the other end.


If you want to maintain proportions while scaling, make sure that you select a length that spans both directions (horizontal and vertical) of your plan.

Step 4: Enter Desired Dimensions

In this step, we will enter our desired dimensions for scaling our plan accurately. Go to Edit > Scaled Drawing... A dialog box will appear, allowing you to enter the known length you measured in the previous step and the desired length for that dimension.


The known length is often referred to as the “original measurement,” while the desired length is called the “new measurement.”

Step 5: Apply Scaling

After entering the desired dimensions, click OK to apply the scaling. SketchUp will automatically resize your plan based on the entered dimensions. You can now see your scaled plan in SketchUp’s modeling window.

Step 6: Verify and Adjust

It’s always a good practice to verify your scaling by measuring another known length on your plan. Use the Tape Measure Tool again to measure a different dimension and compare it with its original measurement. If there are any discrepancies, repeat steps 4 and 5 until you achieve accurate scaling.


If your plan contains multiple dimensions, repeat steps 3-5 for each dimension you want to scale. Keep in mind that maintaining proportions across multiple dimensions is essential for accurate scaling.


You have successfully learned how to scale a plan in SketchUp. Scaling allows you to adjust your model’s size accurately, ensuring that it aligns with your design requirements. Remember to double-check your measurements and maintain proportions throughout the process.

  • TIP: It’s always a good practice to work with a backup of your original plan before scaling, so you can revert if needed.
  • TIP: If you are working on an architectural project, consider using real-world measurements when scaling your plans.

Now it’s your turn! Open SketchUp, import a plan, and practice scaling using the steps outlined in this tutorial. Happy scaling!
