How to Set Paper Size in Layout AutoCAD?

Understanding Paper Size Settings in AutoCAD

To effectively manage your drawings in AutoCAD, setting the correct paper size in layouts is crucial. By following these detailed steps, you can ensure that your output matches your desired specifications.

Step 1: Open Your Drawing

Begin by launching AutoCAD 2025 and opening the drawing file for which you want to set the paper size. This will give you access to its layout settings.

Step 2: Access the Layout Tab

At the bottom of the AutoCAD workspace, locate the layout tabs next to the model space tab. Click on the specific layout tab you wish to modify. If you need to create a new layout, right-click any existing layout and select “New Layout.”

Step 3: Open the Page Setup Manager

1. Right-click on the layout tab.
2. From the context menu, select “Page Setup Manager.” This will open a dialog box displaying all available page setups.
3. Here, you can choose an existing setup or create a new one by clicking the “New” button.

Step 4: Configure Paper Size

Within the Page Setup Manager:

1. Select the layout setup you want to modify and click “Modify.”
2. In the Page Setup dialog, find the “Paper Size” dropdown menu.
3. Scroll through the list to select your desired paper size, such as A3 or A1. If the size you need is not listed, you may need to create a custom size.

Step 5: Adjust Other Settings

In this dialog, ensure you configure other important settings:

• Plot Area: Choose "Layout" to print the entire layout.
• Plot Scale: Define the scale that matches your intended output.
• Printer/Plotter: Select the printer or plotter you will use for the output.

Step 6: Save Your Settings

Once you have adjusted the paper size and any other necessary parameters, click “OK” to apply the changes. This will save your settings for future use.

Step 7: Test Your Layout

It’s advisable to run a test plot of your layout to ensure everything appears as intended. To do this:

1. Go to the "Output" tab in the ribbon.
2. Select “Plot” from the options.
3. Review the print preview to confirm dimensions and scaling before proceeding with the actual print.
