“88 weighted keys” is the most abused phrase in the digital piano aisle. It gets slapped on instruments that have a real graded hammer action and on boards that only have a light spring under each key. They are not the same instrument, and buying the wrong one is the single most common regret we hear from new players. Here’s how to tell them apart — and the pianos that have the real thing at every budget.
The three “weighted” claims, decoded
- Fully weighted / graded hammer action — real hammers inside, graded so the bass is heavier than the treble. This is what “weighted” should mean. Examples: Yamaha GHS/GHC, Roland PHA-4, Casio Smart Scaled Hammer Action.
- Semi-weighted — a spring or light weight adds resistance, but there’s no hammer. Faster and lighter; common on synths and cheaper 88-key boards. Example: the standard Alesis Recital.
- Touch-sensitive (velocity-sensitive) — the key only measures how hard you hit it to change volume. That is not weighting at all, even though listings sometimes imply it is.
If a listing says “weighted” but never says hammer action, assume it’s semi-weighted until proven otherwise.
Best truly weighted digital pianos at a glance

| Yamaha P-225 | Best overall feel | GHC graded hammer | ~$750 | ★★★★★ |

1. Roland FP-10 — Best Weighted Action for the Money
Roland FP-10
- PHA-4 Standard hammer action — the real mechanism from Roland's pricier pianos.
- Graded so the bass keys genuinely feel heavier than the treble.
- Small onboard speakers; headphones recommended for serious practice.
No board near $500 matches the FP-10’s key feel, full stop. Roland put its genuine PHA-4 hammer action in its cheapest piano, which is exactly why teachers keep recommending it over flashier rivals. If your goal is to learn properly on a real action without overspending, this is the one. It’s a heavy box to ship — try Amazon Prime free for 30 days for the fast two-day delivery.
2. Yamaha P-225 — Best Overall Feel
Yamaha P-225
- GHC (Graded Hammer Compact) action — a clear step up from Yamaha's GHS boards.
- CFX grand sample pairs a great action with a great sound.
- Still slim and light enough to move room to room.
The P-225’s GHC action is the sweet spot of Yamaha’s lineup: heavier and more nuanced than the GHS in the P-45/P-145, without the bulk and cost of a console piano. Pair that with the CFX sample and you get a genuinely satisfying instrument to grow into.
3. Casio PX-S1100 — Best Slim Hammer Action
Casio PX-S1100
- A full Smart Scaled Hammer Action in the slimmest 88-key body on the market.
- Simulated ebony/ivory key tops for grip.
- A touch lighter and more clicky than the Roland and Yamaha actions.
Casio deserves real credit for fitting a true hammer action into a chassis this thin. If space or portability is a constraint but you refuse to drop to semi-weighted keys, the PX-S1100 is the answer. The action feels slightly lighter than the big two, but it is unquestionably a real hammer action.
4. Alesis Recital Pro — Best Budget Hammer Action
Alesis Recital Pro
- Hammer-action keys — the Pro is the Alesis that is actually weighted.
- Big onboard voice list and a simple learning layout.
- Action is stiffer and less refined than Roland/Yamaha, but it's a true hammer action.
This is the model people mean when they ask about “the weighted Alesis.” The Recital Pro has a hammer action; the standard Recital does not. If budget is the hard limit and you still want real weighted keys, the Recital Pro gets you there — just temper expectations on how polished that action feels next to a Roland.
How to verify “weighted” before you buy
- Search the product page for the exact phrase “hammer action.” If it’s not there, it’s probably semi-weighted.
- Look for a named action: GHS, GHC, PHA-4, Smart Scaled Hammer Action. Named actions are real actions.
- Be suspicious of “88 weighted keys” with no action name and a sub-$300 price — that combination almost always means semi-weighted.
- Still unsure whether you even need weighting? See digital piano vs keyboard.
The bottom line
For a true weighted action, the Roland FP-10 is the best value in the category, and the Yamaha P-225 is the best overall feel if you can stretch the budget. Whatever you choose, confirm the words hammer action appear on the listing — “weighted” alone is a marketing word, not a guarantee. New players who skip this step are the ones who end up re-buying within a year.
