Digital Piano Comparison Chart 2026: 12 Popular Models Compared

By FindKeyboard.com  ·  Updated 2026-11-02

This chart puts 12 of the most cross-shopped 88-key digital pianos from Yamaha, Roland, Casio, Kawai and Korg side by side: key action, polyphony, speaker power, Bluetooth, weight and a rough price band. Every spec comes from the manufacturer's own spec page, manual or catalog (sources at the bottom). Where we could not confirm a number, we left it out rather than guess.

Short version: under about $550, the Yamaha P-145, Roland FP-10, Casio PX-S1100, Casio CDP-S110 and Korg B2 all give you 88 weighted keys, and they differ mainly in polyphony, Bluetooth and outputs. Spending more mostly buys more polyphony, stronger speakers, proper line outputs and, at the top, wooden or hybrid keys and three pedals.

*Roland notes that the FP-10's Bluetooth may not be included depending on the country of purchase. Weights are the piano alone (FP-30X with music rest); cabinet models (PX-870, YDP-165) include their stand and pedals. Price bands are rough US street prices at the time of writing and move a lot around sales such as Black Friday; use the Amazon links below for the live price. All 12 have 88 full-size weighted keys and a sustain pedal input.

How to Read the Chart

Key action

The action is the mechanism under the keys, and each brand gives theirs a name: Yamaha GHC, GHS and GH3, Roland PHA-4 and PHA-50, Casio Scaled Hammer Action, Kawai RHC, Korg NH. All 12 in this chart are weighted hammer actions, and most of the makers describe them as graded or scaled, meaning heavier in the bass and lighter in the treble like an acoustic piano. Roland lists escapement on PHA-4 and PHA-50. The PHA-50 uses wood and plastic hybrid keys, which none of the cheaper models here have. Feel is personal, so if you can, try the actions in a store; if you can't, our Yamaha P-145 vs Roland FP-10 comparison goes deeper on the two best-known entry actions.

Polyphony

Polyphony is how many notes the piano can sound at once. Held notes, notes ringing under the sustain pedal and layered sounds all count, so the number runs out faster than you'd expect. Casio's own CDP-S110 manual says notes are cut off once you exceed its 64-note maximum (32 for some tones). 64 is usually fine for early beginner pieces; 128 to 256 gives far more headroom for pedal-heavy music and layers. Roland lists the FP-90X's piano tones as having no polyphony limit when played solo.

Speakers

The chart lists amplifier power per side as the makers state it. More watts means more headroom before the sound strains, which matters if you play through the speakers in a bigger room, but watts alone don't tell you how a piano sounds. If you mostly practise on headphones, this column matters least.

Bluetooth: audio vs MIDI

These are two different features. Bluetooth audio streams music from your phone through the piano's speakers so you can play along. Bluetooth MIDI sends what you play to an app (for lessons, notation or recording) without a cable. The FP-10 has MIDI only, the P-225 and DGX-670 have audio only, and the FP-30X, FP-90X, ES120 and PX-S1100 (through its included adaptor) have both. Every model here can still connect to apps by USB.

Weight and size

Portable "slab" pianos in this chart weigh about 10.5–15 kg; the FP-90X and DGX-670 are about 21–24 kg; the cabinet pianos are 34–42 kg because the stand and three pedals are built in. Not sure you need all 88 keys? See 61 vs 76 vs 88 keys.

Picks by Situation

These picks follow from the specs in the chart, not from hands-on testing. We have not played these pianos side by side ourselves. If none of these situations sounds like yours, let the piano quiz match a model to your room and budget.

Beginner, home practice

Yamaha P-145 or Roland FP-10. Both are around $500 with 88 graded hammer-action keys and a footswitch in the box. The FP-10 has more polyphony (96 vs 64) and Bluetooth MIDI for learning apps; the P-145 is slightly lighter. On Amazon US the Yamaha is listed as the P-145BT, which adds Bluetooth audio. Our best digital pianos for beginners guide covers these in more depth.

Step up from entry level

Kawai ES120 or Roland FP-30X. If you expect to keep playing for years, these two add polyphony (192 and 256), more speaker power (10 W × 2 and 11 W × 2) and both Bluetooth audio and MIDI, while staying portable at 12.5 and 14.8 kg. The Yamaha P-225 is the Yamaha step up from the P-145.

Small apartment

Casio PX-S1100. Casio lists it at 232 mm deep and 11.2 kg, it can run on six AA batteries, and it has two headphone jacks, so a teacher or parent can listen in quietly. The Casio CDP-S110 has the same 232 mm depth and is even lighter (10.5 kg), with 64-note polyphony and no Bluetooth.

Gigging, church or school hall

Look for dedicated line outputs so you can feed an amp or PA. Roland FP-30X has Output (L/Mono, R) jacks, 256-note polyphony and 11 W × 2 speakers at 14.8 kg. The Yamaha P-225 has AUX OUT and is lighter (11.5 kg). The Roland FP-90X adds a mic input, MIDI ports and the strongest speakers here. By contrast, the P-145, FP-10, CDP-S110 and Korg B2 send sound out through their headphone jack. More in our Yamaha P-145 vs P-225 comparison and best digital piano for church guide.

Tightest budget

Korg B2 or Casio CDP-S110. Both still give you 88 weighted keys. On paper the B2 has more polyphony (120 vs 64) and stronger speakers (15 W × 2 vs 8 W × 2); the CDP-S110 is lighter and can run on batteries. Neither has Bluetooth. If your budget can stretch a little, the FP-10's 96-note polyphony and Bluetooth MIDI are the next step up.

Home furniture piano

Casio PX-870 or Yamaha YDP-165. Both come with a cabinet stand, three pedals (damper, soft, sostenuto) and 20 W × 2 speakers. The PX-870 has more polyphony (256 vs 192); the YDP-165 uses Yamaha's GH3 action with synthetic ebony and ivory keytops. Want rhythms and backing bands instead? The Yamaha DGX-670 combines GHS weighted keys with 263 accompaniment styles.

When to Skip the Chart and Take the Quiz

A chart is great when you already know what matters to you. It is less helpful if you are torn between two rows, buying for a child or a partner, or not sure whether you even need weighted keys. In that case, answer 3 questions and get a personalized piano match: you can describe your situation in your own words (for example "beginner, small flat, mostly headphones, under $600") and get models with the reason each one fits.
