Keyboard wear
How long will your keyboard switches last?
A switch rating counts presses of one key, and the busiest key, the space bar, takes about 19 percent of English typing. At my average of 12,260 keys a day, a switch rated for 50 million presses reaches its rating in about 60 years. Put in your own numbers below.
Not sure how many keys you press a day? TypeCount counts them on Windows 10 and 11. It counts how many keys, never which, so it cannot tell you which key wears fastest.

What does a keyboard switch rating mean?
It is the number of presses one switch is built to survive in its maker’s tests, not a figure for the whole keyboard. Cherry rates its MX Red, Black, Brown and Speed Silver switches at more than 100 million keystrokes, up from 50 million before 2020. A rating is a test average, not a promise for every switch.
Which key wears out first?
The one you press most. In a classic count of 20,000 English words, the space bar was 18.7 percent of all characters and E was 10.8 percent, so in prose the space bar wears first. Coding, gaming and editing change that, so set your own share. TypeCount never records which keys you press, so it cannot measure this for you.
Published ratings, and who says so
| Switch | Rated presses | Source |
|---|---|---|
| Cherry MX Red, Black, Brown, Speed Silver (2020 on) | More than 100 million | Cherry |
| Cherry MX, earlier figure | 50 million | Cherry |
| Razer optical switches (Huntsman range, clicky and linear) | Up to 100 million | Razer |
| Kailh BOX V2 (Brown listing) | 80 million | A retailer’s listing, Divinikey |
| Gateron KS-3 series | 50 million | Deskthority community wiki, which cites no source for it |
Logitech publishes no press count for its GX switches, only that they are more durable than standard mechanical switches. I found no laptop or membrane keyboard maker whose rating I could open and check, so there is no preset for those. Makers revise these figures; Cherry has changed its own twice.
Wondering whether a switch has already failed? The online keyboard tester shows dead keys and doubled presses.
Can a switch fail before its rating?
Yes. A rating is a statistical average from lab tests, and dust, spills, chatter (one press typed twice) or the keyboard’s own electronics can fail first. On the Deskthority forum, one poster estimated he replaced three Gateron switches after about 3 million presses each, and that two Cherry MX Browns failed after about 6 million. He suspected the Browns were defective. Those are one person’s estimates.
How long do mechanical keyboards last?
No maker I checked publishes a lifespan for a whole keyboard, only for its switches. Cables, controllers, stabilisers and keycaps carry no rating. At my pace a 50 million switch reaches its rating in about 60 years, so for ordinary typing the rating is rarely the first limit. The forum threads I read describe double or missed key inputs and sticky keys instead.
What about a laptop keyboard?
I found no laptop or membrane keyboard maker that publishes a press rating I could open and check, so this page has no preset for them. If your maker gives a number, type it into the calculator as your own rating. The arithmetic is the same: the rating divided by the presses your busiest key takes in a year.
Is that the same as 50 million keystrokes in total?
No. Fifty million presses across every key together would take me about 11 years at 12,260 a day (50,000,000 ÷ 12,260 ÷ 365 = 11.2). A switch rating applies to each key on its own, and each key takes only its share, which is why one switch lasts far longer. My daily numbers are on how many keystrokes a day.
