Hello peoples! :party: :phones:

I was thinking, why not start a "database" of keyboard key measurements, since this apparently doesn't exist...? Lots of different keyboards, even from the same company, have lots of different width keys, did you know that? Well, I didn't, for a while... Thinner keys are harder to play, is the problem(for me).

I got these measurements by going to Guitar Center with a tape measure and, well, you can figure out the rest. They are pretty accurate, I'd say, since several groups of them go together. I was only interested in 5 octaves(or 1, to calculate 5), so I reckon that can be the 'standard' measurement to compare to/with.

So, let's go ahead and post all the other keyboard's measurements, eh? :) (Measure from the left of the lowest key, to the right of the 61st key)

Thanks & hf!

Thanks for doing this. I had assumed that there was a standard.

I measured 61 keys on my acoustic piano and got 33 3/8. It's a Charles R. Walter upright.

Korg Wavestation EX : 32.52 " (for 61 keys)

Yamaha Motif ES 7 : 32.52 " (for 61 keys)

Both seem to have the same size.
