If you have difficulty reading the text on your screen, you can always use the Windows Magnifier to enlarge parts of the screen. But if you are looking to make the change permanent, you can do that too.
Make text larger or bigger in Windows
Open Control Panel > Appearance and Personalization > Display > Make text and other items larger or smaller.
Here you can increase the font size by 125% or 150%. make your selection. This works as follows:
- Smaller – 100% (default). This keeps text and other items at normal size.
- Medium – 125%. This sets text and other items to 125% of normal size.
- Larger – 150%. This sets text and other items to 150% of normal size. This option appears only if your monitor supports a resolution of at least 1200 x 900 pixels.
Click Apply and Logoff.
You will see that all text, including your Start Menu appears bigger now in Windows 10/8/7/Vista.
In Windows 10 you can also open Settings > System > Display and Change the size of text, apps, and other items, by simply moving the slider.
