I think a good typing speed if you need to type a lot would be ideally 80 wpm and minimum 60 wpm. Anything lower than 60 and you'd struggle typing longer texts. I suggest you try TypeRacer - the global typing competition or simply practice touch typing on one of the free typing softwares.
Words Per Minute. In a speed test for typing, every five characters or keystrokes, including spaces, is classed as one word. Speed tests can be taken online on various different websites that enable users to type random passages of text in a set amount of time to determine their typing speed. This is given in wpm (words per minute), with deductions made for each word spelt incorrectly. Therefore, someone who typed 60 words of the passage in one minute and made 4 errors would have a typing speed of 56 wpm.
