If you’re looking for a Casio keyboard with weighted keys, there’s an important distinction to understand before you buy.

Not every Casio keyboard has weighted keys—and even among Casio’s 88-key digital pianos, the keyboard actions aren’t all the same.

Some models are designed primarily for beginners who want an affordable introduction to realistic piano playing. Others offer more sophisticated hammer-action systems intended for experienced pianists who care considerably more about touch and expression.

For 2026, five Casio models stand out at different levels:

Casio CDP-S160 — Best Budget Weighted Casio
Casio PX-S1100 — Best Overall
Casio PX-S3100 — Best for Features and Versatility
Casio PX-S5000 — Best Premium Portable Action
Casio PX-S7000 — Best Premium Design and Home Piano

All five have 88 weighted, hammer-action keys, but there are significant differences in keyboard action, sounds, features, portability and intended use.

Let’s compare them.

Best Casio Weighted-Key Digital Pianos: Quick Comparison

Model	Keys/Action	Polyphony	Tones	Best For
Casio CDP-S160	88, Scaled Hammer Action II	64	10	Budget beginners
Casio PX-S1100	88, Smart Scaled Hammer Action	192	18	Best overall
Casio PX-S3100	88, Smart Scaled Hammer Action	192	700	Versatility
Casio PX-S5000	88, Smart Hybrid Hammer Action	192	23	Premium portable piano feel
Casio PX-S7000	88, Smart Hybrid Hammer Action	256	400	Premium home/design piano

Quick Recommendation

For beginners on a tight budget, start with the CDP-S160.

For the best balance of price, portability and piano-oriented features, our overall recommendation is the PX-S1100.

Choose the PX-S3100 if you want weighted keys but also enjoy experimenting with hundreds of sounds, accompaniment and performance features.

Move up to the PX-S5000 if keyboard action and piano feel are higher priorities.

And if you want Casio’s premium combination of piano performance, sophisticated features and furniture-quality presentation, consider the PX-S7000.

Why Weighted Keys Matter

When you press a key on an acoustic piano, you’re moving a mechanical system that ultimately causes a hammer to strike a string.

That mechanical process creates resistance beneath your fingers.

An inexpensive portable keyboard normally feels much lighter because there isn’t an acoustic hammer mechanism behind the keys.

Digital-piano manufacturers therefore design weighted and hammer-action keyboards to simulate some of the physical characteristics of an acoustic piano.

This matters because your fingers aren’t merely learning which notes to play.

They’re also learning:

How much force to apply
How to control dynamics
How to play softly
How to play loudly without losing control
How to balance notes within chords
How to control repeated notes
How to shape musical phrases

For serious piano practice, keyboard feel can be more important than having hundreds of additional instrument sounds.

Are All Casio Weighted Keyboards the Same?

No.

This is one of the most important things to understand when comparing Casio digital pianos.

The five models in this guide use three different Casio keyboard-action families.

Scaled Hammer Action Keyboard II

Found on:

CDP-S160

This is Casio’s affordable hammer-action solution for its compact CDP series.

Smart Scaled Hammer Action Keyboard

Found on:

PX-S1100 PX-S3100

These Privia models combine compact dimensions with an 88-key hammer-action keyboard.

Smart Hybrid Hammer Action Keyboard

Found on:

PX-S5000 PX-S7000

This is the significant step upward in our comparison.

The keys use a hybrid of wood and resin, giving Casio considerably more scope to create a premium playing experience while maintaining the slim Privia design.

So although all five instruments qualify as weighted-key digital pianos, don’t assume they’ll feel identical.

1. Casio CDP-S160 — Best Budget Weighted Casio

Best for:

Beginners who want an affordable 88-key hammer-action digital piano without paying for features they may not need.

The CDP-S160 demonstrates something Casio does particularly well:

Putting a full 88-key hammer-action keyboard into a remarkably compact instrument.

Its main specifications include:

88 Scaled Hammer Action Keyboard II keys
3 touch-sensitivity levels plus off
64-note maximum polyphony
10 tones
8W + 8W amplification
MIDI recording
USB MIDI
Duet mode
Damper pedal included
Optional three-pedal support
Battery operation
Approximately 10.5 kg weight

Those specifications aren’t spectacular when compared with premium digital pianos.

But that’s missing the point.

The CDP-S160 is about getting the essentials right.

Why We Like the CDP-S160 for Beginners

A beginner doesn’t necessarily need:

700 sounds
Sophisticated effects
Hundreds of accompaniment patterns
Advanced recording
Professional stage controls

What a piano student does need is a keyboard that helps develop appropriate playing technique.

The CDP-S160 provides 88 hammer-action keys in an affordable, portable package.

That’s much more relevant to a serious piano beginner than buying an inexpensive 61-key keyboard simply because it offers hundreds of sounds.

64-Note Polyphony: Is That Enough?

The CDP-S160’s 64-note polyphony is considerably lower than the 192 notes available on the PX-S1100, PX-S3100 and PX-S5000.

But for typical beginner practice, it should be adequate.

Higher polyphony becomes more important as arrangements become more complex, particularly when:

Using sustain extensively
Layering sounds
Playing complex repertoire
Using accompaniment
Working with more sophisticated arrangements

For straightforward piano practice, 64-note polyphony shouldn’t automatically disqualify the CDP-S160.

Extremely Compact

The CDP-S160 is only about 232 mm deep and weighs approximately 10.5 kg.

That’s useful for:

Apartments
Bedrooms
Small music rooms
Students
People who need to store the piano after practice
Musicians who occasionally transport their instrument

It can also run on batteries, adding another level of flexibility.

Who Should Buy the CDP-S160?

Choose it if:

You’re a beginner.
You want 88 weighted keys.
Your budget is limited.
You don’t need hundreds of sounds.
Space is limited.
Portability matters.
Your primary purpose is learning piano.

If your budget allows more, however, the PX-S1100 is worth considering.

2. Casio PX-S1100 — Best Overall Casio Weighted Digital Piano

Best for:

Beginners through intermediate players wanting an excellent balance of piano feel, sound, portability and value.

If we had to recommend one model from this list to the widest range of buyers, it would be the PX-S1100.

It offers:

88 Smart Scaled Hammer Action keys
5 touch-sensitivity levels plus off
Multi-Dimensional Morphing AiR sound source
192-note polyphony
18 tones
60 built-in songs
8W + 8W amplification
MIDI recording
Audio recording
String resonance
Damper resonance
Key-action noise simulation
Duet mode
Optional three-pedal support
Wireless MIDI and audio adapter
Battery operation
Approximately 11.2 kg weight

That’s an impressive package for such a slim instrument.

Why the PX-S1100 Is Our Best Overall Pick

The PX-S1100 strikes a particularly attractive balance.

It’s more sophisticated than the entry-level CDP-S160 without becoming unnecessarily complex.

You get better polyphony, Casio’s AiR sound engine, acoustic-simulation features, wireless connectivity and more recording capability.

But the instrument remains extremely compact.

This makes it suitable for:

Piano students
Adult beginners
Intermediate players
Apartment dwellers
Home practice
Musicians who need portability

Piano Sound and AiR Technology

Casio uses its Multi-Dimensional Morphing AiR sound source in the PX-S1100.

Digital-piano sound isn’t simply about recording one piano note and playing it back whenever you press a key.

The challenge is reproducing how an acoustic piano changes according to:

Playing intensity
Sustain pedal use
Resonance between strings
Key release
Other physical interactions

The PX-S1100 includes acoustic-simulation features such as string and damper resonance to make the playing experience more responsive.

192-Note Polyphony

Moving from 64-note polyphony in the CDP-S160 to 192 notes gives the PX-S1100 considerably more headroom.

Remember that sustained piano notes continue consuming polyphony even after your fingers leave the keys.

For more advanced playing, generous polyphony helps reduce the likelihood of notes being cut off prematurely.

Wireless Connectivity

The included wireless adapter provides Bluetooth audio and MIDI capability.

That makes it easier to integrate the instrument with compatible:

Phones
Tablets
Music apps
Learning applications

You can also use Casio Music Space.

Who Should Buy the PX-S1100?

Choose it if:

You want a serious first digital piano.
You want 88 weighted keys.
You value portability.
You want stronger piano features than the CDP-S160.
You don’t need hundreds of instrument sounds.
You want Bluetooth capability.
You want a digital piano that you won’t immediately outgrow.

For many home players, the PX-S1100 may be all the digital piano they actually need.

3. Casio PX-S3100 — Best for Features and Versatility

Best for:

Players who want weighted piano keys plus a huge sound library, rhythms, accompaniment and creative features.

The PX-S3100 is an interesting instrument because it combines two worlds.

It gives you the same general Smart Scaled Hammer Action keyboard family as the PX-S1100, but adds a dramatically larger collection of sounds and performance features.

Highlights include:

88 Smart Scaled Hammer Action keys
5 touch-sensitivity levels plus off
Multi-Dimensional Morphing AiR sound source
192-note polyphony
700 tones
200 rhythms
Automatic accompaniment
310 music presets
100 arpeggiator types
Pitch-bend wheel
Two assignable knobs
96 registration setups
MIDI recorder
Audio recorder
8W + 8W amplification
Bluetooth audio/MIDI via included adapter
Approximately 11.4 kg weight

This is much more than a straightforward piano.

PX-S1100 vs PX-S3100

This is probably the most important comparison for many buyers.

Both have:

88 keys
Smart Scaled Hammer Action
192-note polyphony
AiR sound technology
Compact dimensions
Built-in speakers
Wireless capability
Battery operation

So why buy the PX-S3100?

Features.

The PX-S1100 provides 18 tones.

The PX-S3100 provides 700.

It also gives you 200 rhythms, automatic accompaniment, registrations, arpeggiator functions, pitch bend and assignable controls.

Who Needs 700 Sounds?

Not everyone.

If you’re primarily studying classical piano, you may spend nearly all your time using one or two acoustic-piano sounds.

In that case, the PX-S1100 may make more financial sense.

But if you play:

Pop
Rock
Jazz
Worship music
Contemporary music
Arrangements
One-person performances

the PX-S3100’s versatility becomes much more attractive.

Who Should Buy the PX-S3100?

Choose it if:

You want weighted piano keys.
You also enjoy keyboards and synthesizer-style features.
You want hundreds of sounds.
You use accompaniment.
You perform.
You compose or arrange.
You want more controls than the PX-S1100 provides.

Think of it as a digital piano that also wants to be a versatile performance keyboard.

4. Casio PX-S5000 — Best Premium Portable Action

Best for:

Pianists who prioritize keyboard feel but still want a remarkably slim and portable digital piano.

This is where our comparison changes significantly.

The PX-S5000 introduces Casio’s Smart Hybrid Hammer Action Keyboard.

Its keys use a hybrid of wood and resin.

Specifications include:

88 Smart Hybrid Hammer Action keys
Hybrid wood/resin key construction
5 touch-sensitivity levels plus off
Multi-Dimensional Morphing AiR sound source
192-note polyphony
23 tones
60 built-in songs
Acoustic simulation
MIDI and audio recording
8W + 8W amplification
Wireless MIDI/audio adapter
Optional three-pedal support
Battery operation
Approximately 11.5 kg weight

Why the PX-S5000 Is Different

Compare its 23 tones with the PX-S3100’s 700 and you might initially wonder why the PX-S5000 belongs higher in the range.

The answer is simple:

The PX-S5000 isn’t primarily about giving you more sounds.

It’s about giving the pianist a more sophisticated keyboard action.

This illustrates an important lesson when buying a digital piano:

More features do not necessarily mean a better piano.

A serious pianist may happily trade hundreds of sounds for a more satisfying action.

Smart Hybrid Hammer Action

Casio’s Smart Hybrid Hammer Action keyboard uses keys made from a combination of wood and resin.

It also incorporates digital scaling and hammer-response technologies designed to create differences in playing response across the keyboard.

The goal is a more nuanced piano-playing experience while maintaining the exceptionally slim Privia form factor.

PX-S3100 vs PX-S5000

This is another important choice.

Choose PX-S3100 if you prioritize:

Sounds
Rhythms
Accompaniment
Performance controls
Versatility

Choose PX-S5000 if you prioritize:

Piano action
Key feel
Piano practice
Simplicity
Premium playing experience

Neither is automatically “better.”

They’re aimed at different players.

Who Should Buy the PX-S5000?

Choose it if:

Piano feel matters more than hundreds of sounds.
You’re an intermediate or experienced pianist.
You want a premium portable digital piano.
You value the hybrid wood/resin keyboard.
You want a sophisticated instrument without a large cabinet.
You need something relatively easy to move.

5. Casio PX-S7000 — Best Premium Design and Home Piano

Best for:

Players who want premium Casio piano technology combined with a distinctive furniture-style instrument for the home.

The PX-S7000 sits at the top of this comparison.

Like the PX-S5000, it uses Casio’s Smart Hybrid Hammer Action Keyboard with hybrid wood/resin keys.

But the PX-S7000 goes considerably further in presentation, sound options and acoustic simulation.

Highlights include:

88 Smart Hybrid Hammer Action keys
Hybrid wood/resin key construction
5 touch-sensitivity levels plus off
256-note maximum polyphony
400 built-in tones
Advanced acoustic simulation
Built-in speaker system
Wireless MIDI/audio adapter
Included stand
Included fixed three-pedal unit
Battery operation
Premium furniture-oriented design

Unlike many digital pianos, the PX-S7000 is designed to look attractive from multiple angles rather than simply being pushed against a wall.

That makes it particularly interesting for modern living spaces.

Piano Meets Interior Design

Most portable digital pianos look like electronic instruments.

Most console digital pianos look like traditional piano furniture.

The PX-S7000 takes a different approach.

Its integrated stand and contemporary design make it much more visually distinctive.

That matters if the piano will occupy a prominent position in:

A living room
An open-plan home
A studio
A modern apartment
A professionally designed interior

A piano is a musical instrument, but in a home it is also a large piece of furniture.

Casio clearly recognizes that with the PX-S7000.

More Than Good Looks

The PX-S7000 isn’t simply an expensive cabinet around an ordinary keyboard.

Its Smart Hybrid Hammer Action system puts it into the premium action category alongside the PX-S5000.

It also raises maximum polyphony to 256 notes and provides 400 tones, making it significantly more versatile than the PX-S5000.

Its acoustic-simulation capabilities are also more extensive.

PX-S5000 vs PX-S7000

Choose PX-S5000 if:

You want premium action.
Portability matters.
You don’t need hundreds of sounds.
You want to keep the instrument relatively simple.

Choose PX-S7000 if:

The piano will stay primarily at home.
Appearance matters.
You want an integrated stand and pedals.
You want more sounds and premium features.
You’re willing to pay more for the complete package.

Who Should Buy the PX-S7000?

Choose it if:

You want one of Casio’s premium digital pianos.
You care about both playing experience and design.
The piano will be part of your living space.
You want a three-pedal setup.
You want substantially more sounds than the PX-S5000.
Portability isn’t your highest priority.

Casio Weighted-Key Actions Explained

Let’s simplify the entire lineup.

Level 1: Scaled Hammer Action Keyboard II

CDP-S160

Best for:

Budget-conscious beginners.

Level 2: Smart Scaled Hammer Action

PX-S1100 PX-S3100

Best for:

Beginners through intermediate players wanting a slim Privia digital piano.

Level 3: Smart Hybrid Hammer Action

PX-S5000 PX-S7000

Best for:

Players who put greater emphasis on piano touch and keyboard feel.

The important point is that you shouldn’t choose a Casio weighted digital piano based only on the words “88 weighted keys.”

The specific action matters.

Which Casio Weighted Piano Is Best for Beginners?

For most beginners, we’d narrow the choice to:

CDP-S160

Best if keeping the purchase price low is the priority.

PX-S1100

Best if your budget allows you to invest in an instrument with more room for progression.

The PX-S1100 would be our preferred choice if affordable because its 192-note polyphony, AiR sound engine, acoustic simulation and connectivity make it a more complete long-term instrument.

[Internal link: Best Digital Pianos for Beginners]

Which Is Best for Classical Piano Practice?

If classical practice is a major priority, keyboard action becomes especially important.

We’d look closely at:

PX-S5000

and

PX-S7000

because of their Smart Hybrid Hammer Action keyboards.

However, beginners shouldn’t assume they need the most expensive instrument immediately.

The PX-S1100 can still be a very capable practice instrument for many students.

[Internal link: Best Digital Pianos for Classical Music Practice]

Which Casio Weighted Piano Is Most Portable?

The CDP-S160 is the lightest of our five recommendations at approximately 10.5 kg.

The PX-S1100, PX-S3100 and PX-S5000 remain surprisingly portable considering they contain full 88-key hammer-action keyboards.

This is one of the major strengths of Casio’s compact digital-piano designs.

If you’re regularly transporting the instrument, also consider:

Overall weight
Stand weight
Pedals
Protective case
Power supply
Whether you’ll need external amplification

Which Casio Is Best for Home Use?

That depends on what you mean by “home use.”

Small apartment:

PX-S1100

Beginner practice room:

CDP-S160

Home entertainment and multiple sounds:

PX-S3100

Serious pianist wanting premium action:

PX-S5000

Piano as part of the room’s interior:

PX-S7000

[Internal link: Best Casio Keyboards for Home Use]

Casio Weighted Keys vs Semi-Weighted Keys

Don’t confuse these terms.

A semi-weighted keyboard generally adds resistance to the key action but doesn’t reproduce acoustic-piano hammer behavior in the same way as a hammer-action digital piano.

All five models in this guide are intended to provide a more piano-oriented hammer-action experience.

That’s why they’re generally more appropriate for traditional piano study than lightweight synthesizer-style keyboard actions.

[Internal link: Weighted vs Semi-Weighted Keys]

Casio vs Yamaha and Roland Weighted Keys

There isn’t one universally “best” keyboard action.

Touch preference is personal.

Some pianists prefer a heavier action; others prefer something faster or lighter.

Casio’s particular advantage in this comparison is its ability to fit hammer-action keyboards into unusually slim instruments.

Yamaha and Roland also produce excellent weighted digital pianos, so brand shouldn’t be your only consideration.

Compare:

Key resistance
Return speed
Surface texture
Dynamic response
Piano sound
Pedaling
Speaker system
Portability
Price

Whenever possible, play the instruments yourself before buying.

What to Look for When Buying a Casio Weighted Digital Piano

1. Keyboard Action

Don’t stop at “88 weighted keys.”

Identify the actual action.

2. Polyphony

64 notes can be adequate for beginners.

192 or 256 provides considerably more headroom for advanced playing and complex sustain.

3. Piano Sound

For serious piano practice, quality matters more than quantity.

Don’t automatically choose 700 sounds over 18.

4. Speakers

Built-in speakers are convenient, but headphones may be equally important for home practice.

5. Pedals

Beginners may start with a single sustain pedal.

More advanced players should consider a proper three-pedal setup with half-pedaling support.

6. Portability

An 88-key digital piano can still be portable, but stands and pedal systems add weight.

7. Connectivity

Consider whether you need:

USB MIDI
Bluetooth MIDI
Bluetooth audio
Audio recording
Line outputs
App connectivity

8. Your Long-Term Goals

The right piano for your first three months isn’t necessarily the right piano for your next five years.

Think ahead.

Common Mistakes When Buying a Weighted Casio

Buying the cheapest model automatically

The CDP-S160 is excellent value, but the PX-S1100 may be worth the additional investment for committed students.

Buying by number of sounds

700 sounds don’t make the PX-S3100 a better piano than the PX-S5000.

Assuming all weighted keys feel the same

They don’t.

Ignoring pedals

Pedaling becomes increasingly important as your repertoire progresses.

Paying for features you won’t use

A classical pianist may not need hundreds of rhythms and accompaniment patterns.

Ignoring size

Measure your space before buying—even Casio’s slim instruments are more than 1.3 meters wide.
