Weighted keys add resistance that imitates an acoustic piano's action. Semi-weighted keys are lighter and springier. For learning piano, choose weighted keys, ideally a graded hammer action. Semi-weighted is a compromise for low budgets or synth-style playing.
At Online Piano University I teach adults from the first lesson; this is what I recommend to them. It is the same gear my students use for my free 41-lesson course and for my upcoming method book series and its companion app.

My pick
Roland FP-10
Roland lists the FP-10 with an 88-key PHA-4 Standard keyboard with escapement and Ivory Feel. It is the lean way to get a piano-style action, with a pedal switch in the box and a compact body.
What are weighted keys?
Weighted keys resist the finger the way a piano key does and return under it. The resistance is what your hand learns against, and almost everything I teach in the first year depends on it: arm weight, a firm fingertip, a loose wrist, soft versus loud. On very light keys none of those sensations exist, and you can learn where the notes are but not how to play them.
What is hammer action, and what does graded mean?
Hammer action goes one step further than plain weighted keys: it imitates the mechanism of an acoustic piano, in which a key moves a hammer. Graded means the weight changes across the keyboard, heavier in the bass and lighter in the treble, as on a piano. Manufacturers give their actions names. Yamaha lists a graded hammer standard (GHS) keyboard on the P-45 and DGX-670, and a GHC keyboard on the P-145BT and P-225. Roland lists the PHA-4 Standard keyboard, with escapement and Ivory Feel, on the FP-10 and FP-30X.
What are semi-weighted keys?
Semi-weighted keys have some springiness or weight added, but not a hammer mechanism. They feel lighter than a piano. The Alesis Recital, for example, is listed by Alesis with 88 premium full-size semi-weighted keys and adjustable touch response. That adjustable response helps you shape dynamics, but the key still does not push back the way a piano key does.
Weighted vs semi-weighted: how do they compare?
| Model | Key action (as listed) | Keys | Type |
|---|---|---|---|
| Yamaha P-145BT | GHC keyboard | 88 | Weighted digital piano |
| Yamaha P-45 | Graded hammer standard (GHS) | 88 | Weighted digital piano |
| Roland FP-10 | PHA-4 Standard, with Escapement and Ivory Feel | 88 | Weighted digital piano |
| Roland FP-30X | PHA-4 Standard, with Escapement and Ivory Feel | 88 | Weighted digital piano |
| Alesis Recital | Semi-weighted, adjustable touch response | 88 | Semi-weighted |
| Casio CT-S1 | Touch response: 3 levels or off | 61 | Portable keyboard |
Notice that the manufacturer pages say what the action is called, not how it feels. Feel is the thing to test, so if you can, press the keys in a shop. Play one note softly and one note loudly and listen for a difference.
Do beginners need weighted keys?
Yes, if the goal is to play piano. An adult who practices for a year on light keys and then sits at a real piano often cannot play their own pieces: the notes are there and the hand is not. That is a year of work spent building a technique for a different instrument. If the choice is between 61 weighted keys and 88 light ones, weight beats range. I explain the range question in 61 vs 76 vs 88 keys.
When are semi-weighted keys acceptable?
When the budget leaves no room, when you want a synth-style instrument for another purpose, or as a short trial. The Alesis Recital is the one I would consider in this tier. If you start on it, plan to move to a weighted instrument within the year, and learn to use the touch response to make soft and loud sound different.
Which weighted digital pianos do I recommend?
The Yamaha P-145BT is my first pick. The Yamaha P-45 is an older, simpler weighted option, and the Roland FP-30X is a step up in feel and sound. See the best digital piano for adult beginners and digital piano vs keyboard. The whole range is on the digital pianos page.
What is escapement, and do I need it?
Escapement is the small, subtle notch you feel when you press a key slowly on an acoustic grand piano, where the hammer releases from the key. Roland lists escapement on its PHA-4 Standard keyboard; I have not verified it on the other models above. It is a refinement that matters more to advanced players than to a beginner, who should first care that the key is weighted and graded at all. Do not pay a large premium for it in your first instrument.
Does the key action change what I practice?
It changes how. On a weighted action I ask students to play with the weight of the arm behind a firm fingertip, to make a soft note and a loud note sound clearly different, and to repeat fast notes evenly. Those habits are what carry over to every other piano you will ever sit at, so the action you practice on becomes the action your hand remembers.
How can I test the key action myself?
Play a slow scale softly, then loudly, and listen. Repeat a single note quickly and see if the key returns in time. Play a phrase with your weakest fingers, 4 and 5, and notice if they respond. If a keyboard makes everything sound the same no matter how you play, it will not teach you touch.
Where to go from here
Gear only matters if it gets you playing, so here is the path I would take. First, start the free 41-lesson course: the lessons arrive in order, you set the pace, and it is also the foundation for my upcoming method book series and companion app.
Second, record yourself, even roughly, and send your playing to me for feedback. A teacher hearing your real sound is worth more than any purchase on this page.
Third, if you want a teacher beside you, or you are buying for someone who does, a gift certificate for online piano lessons is the gift that actually produces playing. You can also browse the rest of my picks in the OPU shop.

Questions adults ask
What is the difference between weighted and semi-weighted keys?
Weighted keys resist your finger like a piano and, in a hammer action, imitate its mechanism. Semi-weighted keys are lighter and springier, with no hammer mechanism.
Is semi-weighted good enough for a beginner?
It is a compromise. It lets you learn notes and rhythm, but not the touch of a piano. Plan to move to a weighted instrument within a year.
What does graded hammer action mean?
The key weight changes across the keyboard, heavier in the bass and lighter in the treble, as on an acoustic piano, and the key imitates a hammer mechanism.
What is GHC or GHS on a Yamaha?
They are Yamaha's names for its graded hammer keyboards: GHS stands for graded hammer standard, and GHC is the keyboard Yamaha lists on the P-145BT and P-225.
Are fully weighted keys harder to play?
They need a little more finger strength at first, and that is how a pianist's hand gets built. They are the right choice for learning.
