Main trade-off
Yamaha P-225
The music rest increases listed depth to 362 mm, beyond the bare 272 mm body.
Head-to-head
Yamaha P-225 vs Casio PX-S1100: Yamaha records sound to a computer, Casio works away from an outlet
The short answer
Choose the P-225 for direct USB audio into compatible software. Choose the PX-S1100 when battery power and a shallower body make the piano easier to place or move.
Before you choose
The reasoning and the trade-offs
A shallow desk and paper music are separate measurements
The Casio body is 232 mm deep compared with 272 mm for Yamaha. That 40 mm saving is useful before adding a music rest. Yamaha publishes 362 mm with its rest. Casio's bare-body figure does not establish its complete operating depth, so measure the score and cable setup too.
What this is based on
P-225: Depth before music rest 272 mm. PX-S1100: Depth before music rest 232 mm. P-225: Depth with music rest 362 mm. PX-S1100: Depth with music rest Not established in the checked record. Conditional workflow inference from these documented inputs. No matched performance measurement.
Main trade-off
Casio PX-S1100
The music rest and cables need space beyond the bare body.

About this comparison
Yamaha P-225 vs Casio PX-S1100: compare depth before music rest, battery operation, live usb audio interface and the practice routines that change the better choice.
Both are slim midrange hammer-action pianos with two headphone sockets and two-track recording. The choice turns on a wired computer recording routine versus battery-powered placement and the shallowest body.
Winner by situation
Start with what you need it to do
Your available surface depth is the first constraint
The Casio body is 232 mm deep compared with 272 mm for Yamaha. That 40 mm saving is useful before adding a music rest. Yamaha publishes 362 mm with its rest. Casio's bare-body figure does not establish its complete operating depth, so measure the score and cable setup too.
- Yamaha P-225
- Good
- Casio PX-S1100
- Better fit
You record the internal piano sound directly over USB into computer software
The P-225 sends live audio through USB. The PX-S1100 saves audio to a USB flash drive and uses its computer USB connection for MIDI. If you want a piano track directly inside a computer session, Yamaha's route is simpler. If you want a file without opening a laptop, Casio's flash-drive route is useful.
- Yamaha P-225
- Better fit
- Casio PX-S1100
- Caution
You want to practice where no power outlet is available
Casio supports six AA batteries. The P-225 requires its power supply. Battery operation can help when the piano moves to a different room for practice, but it does not solve stand stability or reduce key noise. Include batteries and a proper support in the moving kit.
- Yamaha P-225
- Caution
- Casio PX-S1100
- Better fit
You want a two-track recorder on the piano
Both provide two tracks. Choose by connection and placement needs rather than treating recording as exclusive to either.

Meaningful differences
What changes the fit
| What changes | Yamaha P-225 | Casio PX-S1100 | Why it matters |
|---|---|---|---|
| Depth before music rest | 272 mm | 232 mm | Bare depth excludes the music rest, cable route and comfortable playing clearance. |
| Battery operation | Not established in the checked record | Yes | Check this documented difference against the way you plan to practice. |
| Live USB audio interface | Yes | No | This determines whether compatible software can receive the internal piano sound directly over USB. |
| Audio recording to USB memory | Not established in the checked record | Yes | Saving an audio file to a drive is a different workflow from live USB audio to a computer. |
| Internal recorder tracks | 2 | 2 | Track allocation and independent overdubbing matter more than a large number alone. |
What you give up
Every choice has a cost
If you choose Yamaha P-225
- The selected base offer does not include the furniture stand or three-pedal unit.
If you choose Casio PX-S1100
- USB audio-file recording and Bluetooth share the USB-A socket, so check the connection plan.
Recommendation switch
The decision flips if...
You record the internal piano sound directly over USB into computer software
Choose Yamaha P-225. The P-225 sends live audio through USB. The PX-S1100 saves audio to a USB flash drive and uses its computer USB connection for MIDI. If you want a piano track directly inside a computer session, Yamaha's route is simpler. If you want a file without opening a laptop, Casio's flash-drive route is useful.
Your available surface depth is the first constraint
Choose Casio PX-S1100. The Casio body is 232 mm deep compared with 272 mm for Yamaha. That 40 mm saving is useful before adding a music rest. Yamaha publishes 362 mm with its rest. Casio's bare-body figure does not establish its complete operating depth, so measure the score and cable setup too.
You require a verified winner for mechanical key noise or personal playing comfort
Choose neither. The manufacturer records do not provide a matched test for those outcomes. Try the instruments in your intended conditions.
What matters in practice
Before you choose
What this comparison cannot tell you
- The comparison uses documented specifications and conditional setup reasoning. We have not measured key feel, mechanical noise or speaker performance side by side.
- Dimensions describe the specified body or cabinet. Leave room for the rest, cables, bench and player.
- Check the exact Amazon model, color, supplied accessories, condition and delivery date before ordering.
