How Much Daily Typing Practice Do You Need? Practice Time and Timeline, from Research and Records

Before the details, here is what research and records can and can't say, side by side.

• Known: for the same time, spreading practice out is more efficient

  In Baddeley and Longman's 1978 experiment, the group training one hour a day in one session was the most efficient, and the group training two hours a day in two sessions was the least efficient. The authors concluded that, where feasible, training should be distributed rather than massed.

• Not known: how many minutes a day, and whether short sessions work

  The shortest session in the experiment was one hour. Whether 5, 10 or 15 minutes works equally well is untested, as is how many days a week you need.

• Can't be promised: how many days to reach a given WPM

  In the experiment, learning the whole keyboard took on average roughly 35 to 50 hours (approximate). In Typing Musou's records, people who kept playing were 12% faster after 100 matches and 20% faster after 300, but that counts only people who kept playing. Because people differ so much, I don't tie days to WPM.

Here is what Baddeley and Longman's experiment (Ergonomics, 1978) did. At a British post office, 72 volunteers aged 19 to 46 who said they had never used a typewriter or played a keyboard instrument were split into four groups of 18. They were trained to type postal-code strings of letters and digits on a typewriter. The groups differed in session length (one or two hours) and in sessions per day (one or two).

What stands out in the table is that the most efficient group, one hour a day, needed 12 weeks for 60 hours of training. The four-hours-a-day group finished in 3 weeks but needed more total hours to learn the whole keyboard. “Spreading out” means limiting the amount per day and taking more days.

The paper says two hours is too long for a session and one hour is better, and that one session a day is slightly better than two, though not by much. The participants' own feelings went the other way: the paper says the one-hour-a-day group resented spending 12 weeks on what colleagues learned in 3, and satisfaction ratings were higher in the four-hours-a-day group. A practice schedule that feels easier is not necessarily the efficient one.

Search around and the answers disagree: “10 minutes is enough”, “30 to 60 minutes”, and so on. Here are the research and the operator's own view, kept apart.

• What the research says

  Sessions of up to one hour were more efficient than two hours. One session a day was slightly better than splitting the day into two. And for the same total time, limiting the amount per day and taking more days came out ahead.

• What the research doesn't tell us

  It doesn't tell us how well 5–15 minute sessions work, how many days a week you need, or whether Japanese romaji input behaves the same way. An article that says “10 minutes a day works best” is claiming something this research can't support.

• The operator's view (not research)

  On days when you have the time, up to one hour a session looks sensible, and if you want to do more, spread it over other days. On days when you don't, I think that touching the keyboard briefly makes it easier to keep going. That is only my view; I haven't tested how much a short session helps.

For scale: one Speed Trial run is 60 seconds, and one Mock Combat match lasts at most 180 seconds. Ten minutes fits several runs.

For “how many days?”, there are only three ranges to go on. They come from different places, so they can't be compared on one scale.

At one hour a day, 35 hours is about 35 days. But that is for learning the whole keyboard, not about speed; reaching skilled speeds takes much longer. I couldn't find any research or records that support “X days to Y WPM” for Japanese romaji input.

For what each WPM level means, see Average WPM and Benchmarks. For what to do when you stall, see why your typing isn't getting faster.

I followed the same people who played 100 or more Random Battle matches (CPU matches included), comparing their first 10 matches with their last stretch.

Among 5,127 people with 40 or more matches, the median gain between the first 10 and the last 10 matches was +6.1 WPM (+15.8%), and 88.6% improved. Looking at the trend for each of 4,909 people with 30 or more matches, 63.4% clearly improved, 2.0% got worse, and the rest could not be called either way.

Three cautions. First, these are only people who kept playing, so quick improvers may be over-represented. Second, this counts matches, not days; how many matches someone plays in a day varies, so it can't be converted to days. Third, speed rose while the mistake rate hardly changed, so treat mistakes separately (→ how to reduce typing mistakes).

Much of the gain came from shorter intervals between keys, especially the time to reach a consonant. More on that in why your typing isn't getting faster.

You often read that motor memory consolidates during sleep, but the research is split. Walker et al. (2002) reported that motor speed improved by 20% after a night's sleep, with no significant improvement after the same time awake. By contrast, Pan and Rickard (2015), in a meta-analysis of 34 papers, 88 groups and 1,296 people, concluded that once confounds (differences other than sleep) are removed, there is no evidence that sleep improves motor learning. The argument has continued since (Rickard & Pan 2017).

So this article doesn't claim that practicing just before bed locks it in, or that you must practice daily for that reason. The experimental finding that spreading practice out is more efficient stands apart from the sleep question.

In Baddeley and Longman's experiment, speed was re-tested one, three or nine months after training. It had dropped, by about 30% after nine months, and in most groups it didn't fall much further after the first three months. The paper judges the loss as real but not extreme. In other words, you don't go back to zero.

What happens after a break of a few days wasn't studied. After a break, don't be surprised if the first one or two runs are lower than usual; the safe way back is to measure your current speed again first.

Progress only shows up if you measure under the same conditions. Typing Musou's Speed Trial is 60 seconds with the Samurai at ☆0 and no ultimate skills, so the conditions are the same for everyone. The result screen shows WPM, accuracy, max combo and mistakes.

But the prompts in Speed Trial are random every run, and word length changes how easy they are, so a single run's WPM moves up and down. Compare the best and the middle of several runs rather than a single number. The method below is the operator's suggestion, not something based on research.

1. 01.Treat your first run as a warm-up and don't count it
2. 02.Do three runs on the same day and write down the WPM and accuracy from the result screen, with the date
3. 03.Keep the best and the middle of the three WPM values
4. 04.Measure once a week, on the same day, at the same time of day, with the same way of typing
5. 05.Line up 3–4 weeks and see whether the middle WPM is trending up. Ignore any single run's ups and downs

Don't change how you spell kana midway. Typing し as shi takes 3 keystrokes and as si takes 2, so the spelling changes the keystroke count and therefore WPM. The game accepts any spelling as correct.

What the game remembers as your personal best is damage dealt. To see how your WPM moves, write down the WPM from the result screen yourself. To see where your WPM sits, compare it with Average WPM and Benchmarks.

• Q. Is 10 minutes a day still worth it?

  Whether it is worth it hasn't been tested. The shortest session in the experiment was one hour; 10-minute sessions weren't studied. My own view is that touching the keyboard briefly makes it easier to keep going, but I don't know how large the effect is.

• Q. Isn't two hours at the weekend enough?

  No experiment compared “cram at the weekend” directly with “spread over weekdays”. What the experiment shows is that one-hour sessions were more efficient than two-hour sessions, and that for the same total time, limiting the amount per day and taking more days came out ahead.

• Q. If I skip a few days, do I start over?

  You don't start over. In the experiment, even nine months after training the drop in speed was about 30%. The effect of a few days off wasn't studied. When you restart, first measure your current speed again in Speed Trial.

• Q. Is there a rule of thumb for “X days to Y WPM”?

  No. In the experiment, learning the whole keyboard took on average roughly 35–50 hours, but that isn't about speed. Typing Musou's records count matches, and only for people who kept playing. I found no basis for tying days to WPM.

• Q. Do I need money or an account to practice daily in Typing Musou? Can I use my phone?

  The game itself is free, and every feature works as a guest with no login. You need a PC, or a tablet with a physical keyboard attached; it can't be played on a phone (this learning guide can be read on a phone).

What is known: for the same time, spreading practice out is more efficient, and sessions of up to one hour look better than longer ones. How many minutes a day is best, and how many days to reach a given WPM, can't be promised by research or by records.

Today, measure your current speed in Speed Trial. Write the number down, measure again under the same conditions in a few weeks, and you will see your own progress. If you want to build from the basics, you can start in the Home Position Dojo.
