Finding the right digital piano can be tricky—especially when space is limited but quality can’t be compromised. Good thing there is Casio Privia PX-S1100. It offers the feel of a full-sized acoustic piano without taking over your living room, rehearsal space, or studio.
At just 4 inches deep, this model is designed for musicians who want an authentic playing experience in a modern, space-saving form.
With digital pianos becoming more popular in homes, the PX-S1100 promises to balance sound quality, portability, and sleek design. Let’s take a closer look at how it delivers in each area.
Design and Build Quality
The PX-S1100 is remarkably slim and lightweight, making it ideal for smaller spaces or mobile setups. Its compact footprint doesn’t sacrifice style, either.
Key details include:
- Dimensions: 52.0″ x 9.1″ x 4.0″ (about 43% smaller than earlier Privia models)
- Weight: 24.7 lbs—light enough to carry comfortably
- Finish options: Glossy black, white, or red with subtle gold accents
When powered off, the control panel blends into the smooth top surface. Once turned on, backlit touch-sensitive controls light up, giving it a sleek, modern look. The piano can also run on six AA batteries, offering up to four hours of playtime without needing a wall outlet—handy for performances or outdoor practice.
Keyboard Action and Feel
The PX-S1100 features Casio’s Smart Scaled Hammer Action, giving it a realistic, weighted feel across all 88 keys.
Notable features:
- Simulated ebony and ivory key textures for better grip and moisture control
- Five adjustable touch sensitivity levels, plus a fixed-touch option
- Gradual key weighting from bass to treble, mimicking acoustic response
The one downside? The shorter pivot length. This can make deeper key presses slightly more challenging during complex techniques. For general playing and most users, though, the action feels responsive and well-balanced.
Sound Quality and Features
Sound is powered by Casio’s Multi-Dimensional Morphing AiR engine, known for delivering detailed, expressive tones. The German grand piano voice is especially well-sampled, offering a rich and dynamic range.
The PX-S1100 includes:
- 18 onboard tones, including acoustic and electric pianos, organs, and more
- Acoustic enhancements like damper resonance, string resonance, and key-off simulation
- Built-in speakers: Two oval 16×8 cm drivers powered by 8W + 8W amplification
While the number of tones is limited compared to other models, the overall sound quality makes up for it. The onboard speakers offer clear and full audio, but line outputs are available for external amplification when needed.
Connectivity and Extras
Modern musicians expect modern features, and the PX-S1100 delivers. It supports both wired and wireless connections to suit different setups.
Connectivity options include:
- Bluetooth 5.0 (with included WU-BT10 adapter) for wireless MIDI and audio
- USB-A and USB-B ports for device and computer connectivity
- Two headphone jacks (1/8″ and 1/4″) for quiet practice or duet playing
- Stereo line out jacks (L/MONO, R) for connecting to amps or mixers
The piano also supports:
- USB audio recording and playback
- A 2-track MIDI recorder for basic composition
- Duet Mode, which splits the keyboard into two identical pitch ranges—ideal for lessons
Suitability for Different Players
The PX-S1100 is a versatile option that works well for many different use cases.
- Beginners will appreciate the realistic key response and scaled action that help reinforce good habits from the start.
- Intermediate players will enjoy the expressive control and high-quality tones, especially for classical, pop, and jazz.

The PX-S1100 falls into the mid-range price category, and its value is driven by quality materials, modern features, and space-saving design.
Typical pricing:
- Red and white models: around $611.70
- Black model: around $679.00
Many retailers offer bundles that include stands, benches, and cases. The piano also supports firmware updates, adding to its long-term usability. With a customer satisfaction score averaging 4.4 out of 5 stars across over 100 reviews, it’s a well-regarded choice in its category.
