How Do You Add Stairs in Sketchup?

Adding Stairs in SketchUp

SketchUp is a powerful 3D modeling software that allows users to create and design various architectural structures. Whether you are designing a house, a building, or even an outdoor landscape, stairs are an essential element to consider. In this tutorial, we will guide you on how to add stairs in SketchUp and give your models a realistic touch.

Step 1: Creating a New Project

Before we dive into the process of adding stairs, let’s start by creating a new project in SketchUp. Open SketchUp and click on “File” in the top menu bar.

From the drop-down menu, select “New” to create a new project. You can also use the shortcut Ctrl + N (Windows) or Command + N (Mac).

Step 2: Drawing the Base for Stairs

To begin adding stairs to your model, you need to draw the base where the stairs will be located. Use the Line tool in SketchUp to draw a rectangle or any other desired shape for your stair base. Make sure it is aligned properly with your model’s floor plan.

Step 3: Creating Step Components

Now that you have drawn the base, it’s time to create step components for your stairs. To do this, select the Rectangle tool from the toolbar and draw a rectangle on top of your base as the first step of your staircase. Use accurate dimensions based on your design requirements.

Pro Tip:

To ensure precision while drawing steps, you can use guidelines or input specific dimensions in SketchUp by typing them directly into the Measurements box at the bottom-right corner of the screen.

Step 4: Duplicating Steps

Once you have created one step component, you can easily duplicate it to create the remaining steps of your staircase. Select the Move tool from the toolbar (shortcut: M) and activate it.

Then, click on the step component you created and move it upwards in a straight line while holding down the Ctrl key (Windows) or Option key (Mac). Continue duplicating steps until you have completed your desired number of stairs.

Step 5: Adjusting Stair Dimensions

Now that you have created all the steps, you may want to adjust their dimensions to match your design requirements. To do this, select the Scale tool from the toolbar (shortcut: S) and activate it.

Click on one of the corners of a step and drag it inward or outward to resize it. Repeat this process for each step until they are all adjusted properly.

Step 6: Adding Railings

To make your stairs more realistic, you can add railings. Select the Line tool from the toolbar and draw lines along one side of your staircase to represent railings. You can also use other shapes or components for railings based on your design preference.

Pro Tip:

To ensure consistent railing height, draw guidelines at the desired height before drawing lines for railings.

Step 7: Finalizing Your Stairs

Once you have added railings, take a moment to review your stairs in SketchUp’s 3D view. Ensure that everything is aligned properly and matches your intended design. If needed, make any additional adjustments or modifications before saving your project.


Adding stairs in SketchUp is an important aspect of architectural modeling as it adds depth and functionality to your designs. By following these steps, you can easily create stairs that suit your project’s requirements with precision and accuracy.

Remember to experiment with different styles and designs to bring your models to life. Happy modeling!
