Also, I couldn't order it even if I wanted to, as it currently only sells in the USA and Canada.

Slightly OT:

iternabe Awesome chart. My both hands are ~8.9, but I can only play 10ths at the edges. I wish my fingers were longer, but thinner, as I have some trouble playing white keys near the fallboard without pressing the other white keys accidentally.

      That's my problem too. See, I have pretty large hands (I can reach a 10th easily even playing some keys in between) but chords that have to be played in between black keys and cramped positions with adjacent white and black are very uncomfortable for me. A keyboard with narrower keys than standard would not be playable at all for me.

        How often do you find that a problem? Asking since I'm trying to settle on the dimensions for my DIY project.

            candela I try to avoid it, so I happens not often. But not being able to play an octave easily, would be a [censored].

                Small hands is not always an excuse 😃

                That said, I think I have large hands for a female... (8.5" both hands)... AHHH another complex to add to the growing list 🤓

                  Thanks for the reply! Yes, that has been my thinking as well, that it's not extremely crucial to play comfortable tenths considering how relatively rare they are, if it comes at the cost of not easily getting between the black keys or having to make the black keys extremely narrow, at least as long as eights and ninths are comfortable. Only having to stretch the hand to the absolute limit very occasionally probably isn't likely to cause significant damage.
                  Also, there seems to be an ongoing inflation in desirable hand span. My mom, who took piano lessons in the 1940s and '50s but rarely plays anymore, genuinely wondered why anyone would need to reach more than an octave...

                        Let me put a warning here.

                        Stretching your hands to play wider chords on the piano is not without risks, especially for us who are a bit older. Overstretching can strain the tendons and ligaments in the hands, which may become less elastic over time, increasing the likelihood of discomfort or injury. Additionally, the joints in the fingers, especially those at the base, can experience stress, which is a concern for individuals with conditions such as osteoarthritis.

                        The muscles in the hand and forearm may also tire more quickly when holding wide stretches, potentially leading to overuse injuries like tendinitis. Repeated stretching without proper technique or adequate rest can exacerbate these issues, and older adults, who often recover more slowly from minor strains or inflammation, may find themselves more prone to chronic problems. Finally, excessive stretching could contribute to conditions such as carpal tunnel syndrome or other repetitive strain injuries, which can reduce dexterity and cause persistent discomfort.

                            Animisha Thanks for the warning - appreciate it. 😊

                              Animisha Thank you for writing this! I was thinking to say something similar but you were quicker.

                              It's also a fact that professional pianists with small hands are much more likely to become injured than others, despite having developed very good technique and maintained good warm-up routines over the years, being aware of the risks. So there is no getting around that hand size also matters and can't be stretched away. If it hurts, stop and heal!

                              I applaud the initiative to launch products like the Athena so more people can play pain free and with just normal injury risks. Musical instruments are only that: tools to make music. It makes so much more sense to make them fit the player than the other way around. Especially for their personal instrument where people spend the bulk of their practice time.

                                Animisha Additionally, the joints in the fingers, especially those at the base, can experience stress, which is a concern for individuals with conditions such as osteoarthritis.

                                Just adding that not only is it a concern for people who already suffer from arthritis, the additional wear and tear on the joint cartilages caused by repetitive stretching also increase the risk to develop the condition.

                                  Dunno why - YouTube algorithm seems to think I have small hands. (Nope - my hands are so average sized, it seems they define the average)

                                  Another Asian looking woman giving tips - IMO more practical, more realistic and taking care about health.

                                  I love the chart, it's very revealing and explains why the majority of famous pianists are/were men.

                                  I always knew my hands were large for a woman, but I've just measured them and found that I have a span of 9 inches - it's official, I have "pianist's hands"!!! This delights me, as it seems like some compensation for the fact that I can never buy nice women's gloves because they are always too small, so I have to be content with buying men's gloves.

                                  The keyboard looked interesting and is something that I might be tempted to consider upgrading to in the future, if my DP breaks down or becomes unreliable one day, but not at that price - it is astronomical! Maybe in time the price will come down, but in the meantime there are some other keyboards around with narrower keys, and probably some second hand upright pianos with slightly smaller keys too, so these might be useful for keen pianists who struggle with standard width keys. Anyway, my fingers are not slender, so I might find the 5.5 octave keyboard slightly too narrow for my hands.
