How to resize the start menu in Windows 10
How to resize the start menu in Windows 10 – Does your start menu feel too big or too small? If so, you can easily adjust the size of the Start menu in Windows 10 until it is just right, which can provide you with more space to fix your favorite items or display more desktops.
Resize the start menu in Windows 10
The way to do this. First, launch the “Start” menu by clicking the “Start” button on the taskbar or pressing the Windows key.
After opening the “Start” menu, place the mouse cursor on its edge. The mouse cursor will change to a resize cursor, which looks like a short line with an arrow on each end.

To change the height of the Start menu, place the cursor on the top edge of the Start menu, then hold down the left mouse button and drag the mouse up or down.

As you drag the mouse, the “Start” menu will change size. After finding the desired height, release the mouse button and the “Start” menu will remain in this state.
You can also change the width of the “Start” menu in the following ways: grab the right edge with the resizing cursor, and drag the mouse to make it larger or smaller. When resizing horizontally, the Start menu will capture multiples of your tile size.

Or, you can adjust the height and width at the same time by clicking the upper right corner of the Start menu and dragging the mouse diagonally in or out.

If you enlarge the Start menu, there will be enough space for real-time tiles and shortcuts to favorite apps, websites, and documents. You can even cover the menu on the entire screen as needed.
Or, if you feel that the Start menu is taking up too much space, you can make it smaller. In this way, it will not cover your desktop when it is displayed.
The choice of size is entirely up to you. This is just another way to personalize the system and get the most comfortable Windows 10 experience.
