5 matching models from 30 checkedBest for this need
Our pick

Start with the Casio PX-S1100 if the piano moves between practice spots and needs a shallow body. Choose Yamaha P-225 for direct USB audio and hand-by-hand recording, or Casio PX-770 when a complete shallow cabinet can stay in place.
Choose a digital piano for a shared room by body depth, music-rest clearance, carrying weight and the stand you actually need.

What matters in practice
Choose around the scarce space and the task that happens before every practice session.
Casio PX-S1100 is 1322 mm wide and 232 mm deep. Roland FP-10 is narrower at 1284 mm but deeper at 258 mm. A narrow wall gap and a shallow desk can therefore produce different shortlists. Neither rectangle includes the space where you sit.
P-145BT and P-225 differ by only 4 mm in bare depth. With their music rests, Yamaha lists 320 and 362 mm, a 42 mm difference. If paper music stays open during practice, use the rest-included dimensions before assuming their similar bare sizes settle the choice.
Liano's specification lists 6 kg without batteries or music rest. PX-S1100 lists 11.2 kg without batteries. The lighter Liano uses a light-touch mechanism rather than hammer action. A requirement from your teacher can outweigh the carrying advantage.
PX-770 includes its cabinet and three pedals in a listed 299 mm depth. It weighs 31.5 kg assembled, so it suits a permanent station rather than a daily carry. Compare the complete room layout, including bench space, against a portable piano that still needs a stable stand.

The music rest and cables need space beyond the bare body.

Yamaha, P-225

Choose instead whenYou want a two-track recorder and direct USB audio in a body below 30 lb.
The music rest increases listed depth to 362 mm, beyond the bare 272 mm body.

Casio, PX-770
The PX-770 packages two headphone sockets, a two-track recorder and three pedals in a 299 mm-deep cabinet. It is useful when the piano can stay assembled between short practice sessions.
Choose instead whenYou want three included pedals and a permanent 299 mm-deep cabinet.
Check the bench separately in the exact Amazon package.

Korg, Liano
At 6 kg before batteries and music rest, the Liano is easier to plan around frequent moves than a weighted portable. Its light-touch LS keyboard is a deliberate alternative to hammer action.
Choose instead whenA 6 kg light-touch keyboard is easier to bring out regularly, and hammer action is not required by your teacher.
Choose a hammer-action model instead if your teacher requires that mechanism.
