The main versions of Windows include several accessibility options, and one of the most important is the magnifier. However, its factory design has limitations, and it is quite common that its access is not enabled on all machines for administrative reasons. Fortunately, finding an alternative magnifier and more advanced is not complicated. If you want to know how to enlarge the screen in Windows without too much effort, the first step is to download a copy of OneLoupe, which takes up less than 200 kilobytes.

How to enlarge the screen in Windows

We have all paid the price of long sessions in front of the computer. At best, our eyes suffer fatigue and lack of hydration, while at worst they end up needing very aggressive correction. Windows recognizes these difficulties and enables several mechanisms to make using the computer easier. Changing the size of fonts appears at the top of the list, but in more serious situations, users favor the magnifier.

Windows 10 and 11 have an entire section dedicated to the magnifier. However, that tool is available in only three formats (docked, full screen, or lens). Enlarging the screen with the magnifier should be an even more flexible process, and that is when we find the OneLoupe application, developed by the SoftwareOK portal (which we know for the DirPrintOK tool for printing folders, and the benchmark IsMyHdOK)

How to Enlarge the Screen with OneLoupe, an Alternative Magnifier

OneLoupe allows us to increase the size of the magnifier and change the zoom easily.

OneLoupe does not depend on a traditional installation and works as a portable application. Although it is possible to specify that it starts with the operating system, the executable must remain in a temporary folder. There are three ways to change the zoom level: using the mouse wheel, the + and – keys on the numeric keypad, and the keys from 1 to 9 (personal favorite). The cursor arrows modify the dimensions of the magnifier, while F11 opens full-screen mode. With the magnifier active, pressing the P key gives us the color value of the pixel under the cursor (although it only reported FFFFFF in my tests), and B is even more useful, creating a screenshot with the enlarged content (the copy stays in the clipboard, and you will need to paste it into your favorite editor).

OneLoupe's context menu.

OneLoupe has three working modes: Normal (essentially a standard magnifier without secondary actions), Real Time, and Real Time with cursor transparency, which we call “Working Mode”. Without a doubt, the latter is the most interesting of the three, since the magnifier becomes an extension of the cursor, accepting all kinds of clicks. These modes use F1, F2, and F3 as keyboard shortcuts (and we can also use OneLoupe's context menu to access them).

Finally, OneLoupe is free software, available in 32 and 64 bits, does not drag local dependencies, and works with all versions of Windows from XP onward. Its interface includes a complete Spanish translation, and the last build was recently updated. Download a copy!
