The catch
Casio PX-S1100
Leave extra room for the music rest and cables on top of the bare body.
Side by side
Pick the PX-S5000 once you have confirmed that its Smart Hybrid Hammer action suits your playing. Choose the PX-S1100 instead if the lower complete price matters more and the portability and practice features they share are mostly what you need.
Before you buy
Before accessories, both are listed at 1322 by 232 by 102 mm, and the PX-S5000 fits its wood-and-resin hybrid mechanism into that same space. So if your room is shallow, you can compare the actions without assuming the hybrid-key option needs a furniture cabinet.
Where this comes from
Keyboard mechanism: PX-S1100 Smart Scaled Hammer, PX-S5000 Smart Hybrid Hammer. Listed width: PX-S1100 1322 mm, PX-S5000 1322 mm. Depth before music rest: PX-S1100 232 mm, PX-S5000 232 mm. This is a conditional workflow inference drawn from these documented inputs. There is no matched performance measurement.
The catch
Leave extra room for the music rest and cables on top of the bare body.
The catch
A particular action design is no proof that it will feel better under your hands.

Casio PX-S1100 vs Casio PX-S5000, compared on keyboard mechanism, listed instrument weight and preset voices, along with the practice routines that decide the better choice.
A shallow portable format, a battery option and recording routes are common to these pianos. What mainly earns the PX-S5000 a place on the shortlist is its different wood-and-resin keyboard mechanism.
Which one fits
Before accessories, both are listed at 1322 by 232 by 102 mm, and the PX-S5000 fits its wood-and-resin hybrid mechanism into that same space. So if your room is shallow, you can compare the actions without assuming the hybrid-key option needs a furniture cabinet.
A two-track recorder, flash-drive audio recording and two headphone sockets are on both. If those are your main requirements, the PX-S1100 already covers them. The PX-S5000 has to earn its place through the action trial or other details that matter to you personally. A generic recording promise is not enough.
Casio lists the PX-S1100 at 11.2 kg without batteries and the PX-S5000 at 11.5 kg without accessories or batteries. The stated bases differ slightly, so do not infer an exact difference for carrying the whole setup. Both still need a stand and the optional SP-34 for three-pedal half-damper practice.
Two tracks are recorded by both. If accompaniment and more recording parts are what you really require, pick a different model.

Spec by spec
| Spec | Casio PX-S1100 | Casio PX-S5000 | In practice |
|---|---|---|---|
| Keyboard mechanism | Smart Scaled Hammer | Smart Hybrid Hammer | Try out the documented mechanism before taking its name as a guarantee about feel or mechanical noise. |
| Listed instrument weight | 11.2 kg | 11.5 kg | Work out the load you will be moving from the stated measurement basis, and then add the stand, case and accessories. |
| Preset voices | 18 | 23 | Additional tones are of use when your playing routine calls for them, and they are not a measure of piano realism. |
| Internal recorder tracks | 2 | 2 | A large number by itself counts for less than track allocation and independent overdubbing. |
| Depth before music rest | 232 mm | 232 mm | The music rest, cable route and comfortable playing clearance are all left out of bare depth. |
Trade-offs
Change of plan
Go with Casio PX-S1100. Two recorder tracks, USB-memory audio recording and two headphone sockets come with both. PX-S1100 is the pick if its exact complete offer is cheaper and a hands-on trial gives you no reason to pay for the hybrid action.
Go with Casio PX-S5000. Smart Hybrid Hammer keys on the PX-S5000 fit the same listed 1322 by 232 mm body rectangle. Only pay for that mechanism if an action trial leaves you with a clear personal preference. PX-S1100 shares its recording tracks and headphone connections.
Neither model fits. Manufacturer records contain no matched test for those outcomes. Try the instruments under the conditions you intend to play in.
