Why is my Microsoft Forms form not allowing me to change the font size?

Check your permission level – Formatting options may not be available if you do not have sufficient permissions within the form.

Verify the question type – Font size changes can only be made under certain question types (e.g. text type questions cannot have their font size changed).

Check browser compatibility – Certain browsers may not be compatible with font size changes or other formatting options.

Clear all temporary files – Clear your browser cache or temporary Internet files, which may have saved old, outdated, or even corrupted files that could be preventing the font size changes from taking effect.
