Do you want new fonts to use in Wordpad but don't know how to install them? This is much easier than you think.
Steps

Step 1. First you have to find a font that you like
If you don't want to pay for one, just Google "free fonts." You will find hundreds of pages to choose from.

Step 2. Select your font

Step 3. Download your font (you will see a "Download" button somewhere on the page)
The fonts you download will be in "WinRAR or ZIP" files.

Step 4. When the download is complete, you must unzip the source
To do so, simply click on the file. Because it is a WinRAR or ZIP file, WinRAR will automatically open to unzip the file. If you don't have WinRAR, you're going to have a little problem (but you can download WinRAR's 50-day trial version for free).

Step 5. When you open WinRAR, select your archive (by clicking on it) and then click on "Extract to" (at the top left of the window, next to "Add")
- If you downloaded more than one font, click "Add" and select the other fonts you want to unzip.

Step 6. After clicking "Extract to", another window will appear asking you where you want to extract the files
It is probably difficult to find the correct folder to unzip the files, so just select "Desktop".

Step 7. When unzipping the fonts they will be in TTF files (truetype)

Step 8. When done, close WinRAR and click "Start" and then "Control Panel"
You should see a folder called "Fonts". On Mac, go to the "Library" and then go to the folder called "Fonts".

Step 9. Put the fonts (from your desktop) in that folder

Step 10. When done, you can close that folder and also delete the WinRAR or ZIP file that you downloaded

Step 11. You are done
You should find the new fonts in "WordPad". (If you don't see them, you will most likely need to restart the program, if you opened it before downloading and unzipping the sources).
