The main question should be: are split keyboards any better than normal keyboard?

When I gave it a look, the studies were on the side of split keyboards being the hardware equivalent of snake oil.

But whatever.

And maybe then: are keyboards the best input device in 2026?

LargoLasskhyfv•3d ago
Maybe it depends on your individual anatomy, and the sensitivity of it to stresses?

Anyway, the fact alone that you have less bend in the joints of your hands, if used right, seems to avoid all sorts of carpal-tunnel syndrome?

jclulow•1h ago
One thing I internalised when speaking with a physiotherapist is that part of avoiding serious issues is making sure you don't stay in the _same_ position for too long. One good ergonomic position is an excellent start, but changing your position several times throughout the work day is even better. This apparently helps avoid building up strain and inflammation in pinch points, balancing out the fatiguing action more.

I have found that my Ergodox allows me to juggle my keyboard halves around the desk at different angles and spaced apart at different widths, and I can put my trackball either to the right of everything or between the halves. It's a single anecdote, obviously, but I have been able to make my ulnar and carpal entrapment issues mostly go away by finding better positions while working and by not staying stuck in one posture or position for too long at a time.

davesmylie•51m ago
completely anecdotally (sample size of one!) but I found big improvement in comfort and posture when i moved to the kinesis ergo (split, but joined) about 15 years ago.

Eventually I moved to a full split, positioned quite some distance apart (~25cm) and found that even more comfortable.

Always hard to know with stuff like this if you are just imagining it, but for various reasons, I'm pretty convinced it was an improvement for me.

Fellshard•40m ago
I can speak anecdotally, at least.

My shoulders are pretty wide for my frame. When using most laptop keyboards and many standard keyboards, I have to tuck my shoulders in and twist my wrists. This was causing some serious pain and tension in my neck, shoulders, and wrists, likely leading toward carpal tunnel.

I made two different changes in succession that helped greatly (and I don't remember the order now):

1. With a split keyboard, the halves could be placed so my wrists are straight and my arms hold at shoulder-width, and this rapidly reduced the amount of tension I was experiencing and gradually eased my wrist issues. Tenting the keyboard and getting a vertical mouse helped as well, but I'd rate those as minor improvements, especially since I aim not to drive with the mouse as much.

2. With Colemak layout, I was able to gradually transition from QWERTY (there's a series of AHK scripts I found at the time that basically rotated triples of keys). This helped reduce wrist strain at the hand level.

for me its the outside angle between my wrist and my forearm. When I any of my splits it removes the angle entirely, and the pain for me is gone.
GlenTheMachine•1h ago
So after almost 50 years of hacking, I'm starting to feel it in my hands. But I don't have any wrist problems -- no carpal tunnel. What I have is tendonitis in my fingers, primarily in my middle fingers and my right pinky (from slamming Enter several million times).

I've had steroid injections into the tendon sheaths of my fingers a couple of times, which hurts like a bugger when it's done but definitely improves things after a few days. It isn't a cure, though, and my hand doctor thinks I'm going to need surgery eventually.

I have to assume that a split keyboard won't help this. Is there anything that might, short of a voice interface?

eschneider•1h ago
Ok, fellow old hacker here. I have a similar problem and I found that a lot of the hand pain was from mouse/trackpad usage. My hands have been a lot happier since going to a trackball because I don't do nearly as much gripping and pressing.
bramhaag•1h ago
A split keyboard might still bring you some relief. Modifiers/enter/backspace/etc are usually moved away from your weakest fingers (pinkies) to your strongest (thumbs). I have Ctrl, Alt, backspace, delete, space, enter and shift all on my thumb clusters.

Here's an example of what that might look like: https://kinesis-ergo.com/wp-content/uploads/KB360-GBR_FRONT-... (though in the default configuration, shift is still on your pinky; you can customize this on most keyboards, or on OS level).

The rabbit hole goes very deep. Another option is home row mods: https://precondition.github.io/home-row-mods. A combination of thumb clusters and home row mods can reduce your finger strain a lot.

w10-1•1h ago
Also the type of the key matters for tendonitis. Some have tactile feedback after the key is pressed but well above the bottom so you learn not to bottom out with force.

https://kinesis-ergo.com/products/#keyboards

(They used to have low-force options; perhaps all are low-force now?)

bramhaag•43m ago
Kinesis also offers custom switch options through Upgrade Keyboards: https://upgradekeyboards.com/collections/kinesis-advantage36...

Lead times are long, and Kinesis products are expensive. It gets a little more bearable if you take into account that you're using this tool 8 hours a day for years and years, but still. Cheaper options exist.

XenophileJKO•36m ago
I can't second Kinesis enough. I have been using them for 20 years now. I was starting to have issues and I haven't have a single issue with my hands or wrists since changing over. Also a good vertical mouse will help if you use a mouse much. I use trackballs or vertical mice interchangably.
aaarrm•1h ago
The angle / position your wrist is when your fingers need to do these lateral movements could be more or less taxing depending.
w10-1•1h ago
This is a summary of Reddit discussions and maker hacks, not of the actual market for ergonomic keyboards. Because the goal of those discussions and hacks is to be distinctive, the summary picture is fascinating but over-complicated.

Kinesis Advantage keyboards have been popular for decades and proven ergonomic benefit - mainly because the cup avoids wrist movement and the high-traffic keys are moved to the stronger thumb. Some users prefer the newer split Professional to avoid constraining arm position. These keyboards stopped my RSI cycle decades ago, and improved my speed by roughly half. (Also a US company, with fantastic support.)

seatac76•1h ago
I got the Kinesis Gaming split 5 years ago and honestly it has been a game changer. My wrist pain went away, takes about a week to get used to it but it has been a welcome change. I also feel like I can type faster on it.

My kingdom for a split keyboard with a traditional layout. I have no interest in chording, layers, or having fewer keys. No numpad if you must cut something. I just want to spread my arms without any additional novelty. No shortage of “vertical” desk space, give me that F-row
walthamstow•35m ago
If you're a Mac user, I have a Keychron that fits this description, the Q11. It's basically a split mechanical MacBook keyboard.
0cf8612b2e1e•23m ago
Almost. I own a Mistel MD770 which does a very similar arrangement. I strongly dislike the non standard home/end/pgup/pgdown positioning.

Had you asked me how often I use those keys, I would have said hardly ever. Now that I have to suffer that layout, I have realized they are crucial for my typing/usage patterns.

tom_•10m ago
I like these: https://eu.perixx.com/products/periboard-535

The F-lock nonsense isn't too awful, you get all of the keys, the layout is pretty standard, you can buy ANSI layout ones in the UK, and there's a full set of meta keys that are usefully symmetrical enough. Also: connects to PC with a wire. No batteries required. (The wonders of modern technology!)

Haven't tried the brown switches.

The red switches are quite light touch with a nice positive action. Very nice to type on for text, where my fingers can get into a good rhythm, but it's a bit too easy to hit the wrong key if I'm going for an arbitrary keyboard shortcut.

The blue switches go click, which feels great to type on, and I've found it does help a bit with the problem of hitting the wrong key (something about the more obvious multimodal feedback gets my subconscious on the job I suppose) - but I never quite got on with the slightly heavier key action.

I used to use the MS Ergo 4000, and I've found this a good replacement. The keyboard layout is very similar, as is the reverse tilt angle, and the palm rest is fine, even if it's IMO inferior to the MS 4000. (But: the MS 4000's reverse tilt stand, a single piece of solid plastic, is significantly more solid than the Perixx's little fold out things. Worth bearing in mind if you're in the habit of resting your elbows on the palm rest when in thought.)

I have multiple of the MSFT Sculpt keyboards. It's wireless. Comes with separate wireless number pad. Now produced by Incase. It has Windows key, but it's easy to remap.

The issue with kinesis and all those nice small symmetrical keyboards is that not every alphabet is as short as English.

Russian, for example, has 33 letters.

So if you’re someone like that, you really want that ordinary macbook-like number of keys = larger non-symmetrical right half.

—

As for the ortholinear keyboards, I spent a few months with the latest kinesis but sold it eventually: not that comfortable.

Just clench your fist and you will see that not all your fingers are moving in direct lines. I don’t buy the ortho logic at all. I would argue that left half of the ordinary keyboard is even more ergonomic in this sense.

—

Tdlr; split, traditional layout https://uhk.io/ is my best purchase: use it for almost 5(?) years. Modded it for swappable switches, lubed, what have you.

Don’t waste money for uhk riser, not worth it. Small plastic built-in legs are more than enough.

Previously was a big fan of microsoft split ergonomics (2nd gen and sculpt later)

I love my uhk, I really wish the 60v2 had bluetooth. I really don't wanna fork over the money for a 80v2. :(
Conscat•19m ago
I've been inputting Devanagari with a 30% ortho keyboard lately using QMK. ये अति मुश्किल नहीं है । I have an extra layer for nicher inputs just as I do with my usual Roman text. I'm not aware of any writing systems that normally require multiple layers. The most complex I can think of is Hangul, and they all should translate pretty directly to a smaller keyboard.

> The issue with kinesis and all those nice small symmetrical keyboards is that not every alphabet is as short as English.

Ironically, the biggest enthusiast of these splits I know in real life (he owns a kinesis) is a slavic guy, speaks both Ukranian and Russian, but I suppose he's typing in English for most of the day at his job, however I know he uses layering for the cyrillic.

Prepare your wallets....
interstice•44m ago
I built one of these and I really wanted to love it, but in the end gave up because I just couldn't get comfortable with 3+ layers. On the lookout for a reasonably aesthetic TKL split - at least until I give in and make my own.

robinsonb5•16m ago
Personally I prefer a keyboard with a gentle curve rather than an actual split - the old Microsoft Comfort Curve 2000 was my favourite for many years, but mine have all failed with membrane issues now.

I'm probably going to end up building a custom board with the features I want (gentle curve, ISO layout, nice switches) since what I want doesn't seem to be available off-the-peg. (The X-Bows keyboards are quite nice, but ANSI-only - I've done enough programming to have learned that I'm not prepared to compromise on the position of "\"!)

Analog desktop synthesisers localise signal to noise ratio as 1:1.

A 2KH sin wave sampling at 1000 Hz reconstructs to 1000 Hz.

No mention of the Kinesis Advantage 360? I was lucky and scored two of them for free, one from the ergo center at my employer, and one from a generous coworker who didn't vibe with his.

There are a lot of keyboards I'd like to try, but I'm pretty happy with these.

incr_me•11m ago
I resent the idea of an absolute standard of ergonomics or typing technique. I often use my left thumb to key z/x/c/v/b. I often reach with my left index finger to key y/h/b. During certain chords, my hands often cross over the split.

I tried multiple split keyboards over the period of 2 years and never grew out of these habits. I always wished, at the least, that some of the middle keys were duplicated between the two halves.

Eventually I received some permission to accept my personal "kinetic signature" (so to speak). Then the chronic wrist pain that led me to try split keyboards in the first place vanished. So I went back to using a normal tenkeyless. This led me to believe that split keyboards were ideal for some people, but that other people (like myself) are predisposed to a sort of perfectionism that entails physical guarding and chronic pain.

I still wish I had a wireless split keyboard for times when I'm supine and need to type, though.

russdill•8m ago
Curious if there are any split keyboards with "overlap", eg, the center of the keyboard is duplicated on both sides
robrtsql•4m ago
My two cents: The Keychron Q11 is a decent choice for a split keyboard which also has a traditional layout and therefore doesn't require any learning. If you don't like the distance, you _can_ push the pieces back together and they'll just resemble a traditional keyboard. And it's definitely the highest build quality of any keyboard I've used this far in my life.

It seems to have this issue (or maybe Macbooks do? I don't know..) where, waking my computer from sleep, the right side of the keyboard doesn't work. It's quickly fixed by unplugging and replugging the right side of the keyboard into the left, or unplugging and replugging the entire keyboard into the computer.. it's a shame that I have to do that sometimes, though.
