How to Change Default Window Size in Windows 11: A Step-by-Step Guide

Changing the default window size in Windows 11 can help improve your workflow and make your computer usage more efficient. This can be done by adjusting some settings in the Windows operating system. Follow these steps to customize the default size of your application windows to suit your needs.

Changing Default Window Size in Windows 11

In the following steps, you’ll learn how to change the default window size in Windows 11. This customization allows you to control the initial size of application windows when they are opened.

Step 1: Open the Application

First, open the application whose default window size you want to change.

When an application opens, it usually adopts the size and position of its previous instance. This is where we’ll start making changes.

Step 2: Resize the Window

Next, resize the window by dragging its edges to your preferred size.

You can adjust the height and width by clicking and dragging the window borders. Make sure to set the window to a size that you find most convenient.

Step 3: Move the Window to the Desired Position

Move the window to the location on your screen where you want it to open by default.

Position the window by clicking and dragging its title bar. Placing it in your desired spot ensures it opens there the next time.

Step 4: Close the Window

Close the resized and repositioned window to save its size and position.

Closing the window ensures that Windows remembers the size and position for the next time the application is launched.

Step 5: Reopen the Application

Reopen the application to check if it opens in the new size and position.

This step verifies that your settings have been saved correctly and the window opens as you customized.

Once you complete these steps, the application should remember the new size and position, opening just the way you like it every time.
