The catch
Yamaha P-225
With the music rest attached, listed depth grows to 362 mm, up from the bare 272 mm body.
Side by side
Yamaha P-225 vs Casio PX-S1100: Yamaha sends recorded sound to a computer, and Casio works away from an outlet
Quick verdict
For direct USB audio into compatible software, pick the P-225. The PX-S1100 is the better fit when battery power and a shallower body make the piano simpler to place or move.
Before you buy
Why, and what it costs you
A shallow desk and a paper score need to be measured separately
Casio's body measures 232 mm deep, against 272 mm for Yamaha. That 40 mm saving helps before a music rest goes on. With its rest, Yamaha publishes 362 mm. Casio's bare-body figure does not tell you its complete operating depth, so measure your score and cable setup as well.
Where this comes from
Depth before music rest: P-225 272 mm, PX-S1100 232 mm. Depth with music rest: P-225 362 mm, PX-S1100 Not established in the checked record. This is a conditional workflow inference drawn from these documented inputs. There is no matched performance measurement.
The catch
Casio PX-S1100
Leave extra room for the music rest and cables on top of the bare body.

What this page compares
Yamaha P-225 vs Casio PX-S1100, compared on depth before music rest, battery operation and live USB audio interface, along with the practice routines that decide the better choice.
Each is a slim midrange hammer-action piano with two headphone sockets and two-track recording. Which to pick comes down to a wired computer recording routine, or battery-powered placement and the shallowest body.

You capture the internal piano sound over USB straight into software on a computer
Live audio goes out through USB on the P-225. The PX-S1100 saves audio to a USB flash drive, and its computer USB connection is used for MIDI. Yamaha's route is simpler if you want the piano track straight inside a computer session. If you would rather get a file without opening a laptop, Casio's flash-drive route helps.

- Better fit
- Casio PX-S1100
- Caution
You plan to practice somewhere without a power outlet
The Casio runs on six AA batteries, while the P-225 needs its power supply. Batteries are handy when the piano moves to another room for practice, but they do nothing for stand stability or key noise. Pack batteries and proper support in the kit you move.

You want the piano to have a two-track recorder
Two tracks come with both. Let connection and placement needs guide the choice, since neither has recording to itself.

Spec by spec
Where they really differ
| Spec | Yamaha P-225 | Casio PX-S1100 | In practice |
|---|---|---|---|
| Depth before music rest | 272 mm | 232 mm | The music rest, cable route and comfortable playing clearance are all left out of bare depth. |
| Battery operation | Not established in the checked record | Yes | Weigh this documented difference against how you plan to practice. |
| Live USB audio interface | Yes | No | Whether compatible software can take the internal piano sound directly over USB depends on this. |
| Audio recording to USB memory | Not established in the checked record | Yes | Live USB audio to a computer is not the same workflow as saving an audio file to a drive. |
| Internal recorder tracks | 2 | 2 | A large number by itself counts for less than track allocation and independent overdubbing. |
Trade-offs
What each pick costs you
With Yamaha P-225
- Neither the furniture stand nor the three-pedal unit comes with the base offer you have selected.
With Casio PX-S1100
- Both USB audio-file recording and Bluetooth use the same USB-A socket, so work out your connection plan.
