How do you make letters bigger on the typewriter?

To make letters bigger on a typewriter, you can use a technique called "double striking," where you press the same key twice for each letter. This will create a bolder impression, making the letters appear larger and darker. Additionally, some typewriters have a "bold" or "wide" setting that can be adjusted for larger text. Always ensure you have the correct ribbon that can handle the extra ink for clearer results.
