    At 1,284 mm (50.6 in) wide, the FP-10 is the narrowest full 88-key piano we compared, with Roland's hammer-action keyboard and Bluetooth MIDI.

Here is the number that decides this purchase: a full 88-key keyboard is about four feet long before you add a case. That sets a floor on width that no design trick gets around, so slim digital pianos land in a tight band of roughly 50.5 to 52.5 inches. If your gap between a doorway and a corner, or between a bookshelf and a radiator, is under about 51 inches, no current full-size 88-key piano we found fits it, and you should look at a shorter keyboard instead.

If you have 51 to 53 inches, though, the differences between models matter, and depth often matters more than width in a small apartment. We pulled the official dimensions for four slim 88-key pianos and ranked them for a narrow wall.

Solved it · Top pick

#1: Roland FP-10

Best for the narrowest wall space

Skip it if you want to play out loud often; its built-in speakers are small.

The FP-10 is the narrowest full-size piano in this comparison at 1,284 mm, or about 50.6 inches, wide, and about 10.2 inches deep with the music rest removed. That extra inch or more compared with the others can be the difference between fitting beside a door frame or not. It does not feel like a budget compromise under your fingers: Roland's PHA-4 Standard hammer action includes escapement and ivory-feel key tops, and the piano tone comes from Roland's SuperNATURAL sound engine. Bluetooth MIDI connects it to learning apps on a tablet. Roland lists the weight at about 12.6 kg, or 28 pounds. The built-in speakers are modest, so plan on headphones for practice, which also keeps neighbors happy.

Why it fits

  • Narrowest full 88-key width in this group
  • Hammer action with escapement

Watch out for

  • Small built-in speakers

#2: Casio Privia PX-S1100

Best when depth matters as much as width

Skip it if every inch of width counts; it's about 1.4 inches wider than the FP-10.

The PX-S1100 is slightly wider than the Roland at 1,322 mm (52.0 inches), but it is the shallowest piano here at just 232 mm, about 9.1 inches, and only about 4 inches tall. In a narrow hallway nook or on a desk where the piano has to share space, that thin profile keeps it from jutting into a walkway. Casio's Smart Scaled Hammer Action gives graded key weight, it has 18 tones and 192-note polyphony, and it can run on six AA batteries, which helps if the only open wall has no outlet nearby. Bluetooth audio lets you play backing tracks through its speakers. At about 11.2 kg, or 24.7 pounds, it is easy to lift onto a stand or slide under a bed.

Why it fits

  • Shallowest and slimmest body
  • Optional battery power

Watch out for

  • About 1.4 in wider than the FP-10

#3: Casio CDP-S160

Best budget pick with the same slim body

Skip it if you plan to use apps or play along with recordings over Bluetooth audio.

The CDP-S160 shares the PX-S1100's compact footprint, 1,322 by 232 mm, or about 52.0 by 9.1 inches, at a lower price. It is a little lighter too, around 10.5 kg without batteries, and like the Privia it can run on six AA batteries. You give up some refinement: it uses Casio's Scaled Hammer Action Keyboard II, has 10 tones and 64-note polyphony, and lacks the PX-S1100's Bluetooth audio. It is the US-market sibling of the CDP-S110 with the same body and specs, sold in black and in colors. For a beginner or a returning adult player who mainly needs weighted keys, the included sustain pedal and a headphone jack in a body that fits a small wall, it covers the essentials.

Why it fits

  • Same shallow 9.1-inch depth for less money
  • Weighted, graded action for practice

Watch out for

  • Fewer sounds, 64-note polyphony, no Bluetooth audio

#4: Yamaha P-225

Best sound and feel if you have 52.5 inches

Skip it if your wall has less than 52.5 inches to spare.

The P-225 is the widest piano in this group at 1,326 mm, about 52.2 inches, and about 10.7 inches deep without its music rest, so measure carefully. If it fits, it is the most polished of the four. Yamaha's Graded Hammer Compact action is designed to keep a weighted feel in a shorter key mechanism, and the piano sound is sampled from Yamaha's CFX concert grand. It weighs about 11.5 kg, or 25 pounds, and adds Bluetooth audio. Yamaha also sells a matching stand that keeps the 1,326 mm width, so the footprint does not grow when you set it up permanently. Choose it if sound quality is the priority and your wall has at least 52.5 inches to spare.

Why it fits

  • Richest sound of the group
  • Matching stand keeps the same width

Watch out for

  • Widest and deepest option here

Quick comparison

With about 51 inches of wall, the Roland FP-10 is the only one of the four that fits. With 52 inches or more, the Casio PX-S1100 is the slimmest choice for a walkway, the Casio CDP-S160 offers the same body for less, and the Yamaha P-225 sounds best if you can spare roughly 52.5 inches.

Depths are without a music rest. Add a little side clearance so the piano is not pressed against a wall or door trim.

Frequently asked questions

How wide is an 88-key digital piano?

Slim portable models run from about 50.5 to 53 inches wide. Console-style pianos with wooden cabinets are usually wider and much deeper.

What if my space is under 50 inches?

A full 88-key piano will not fit. Your options are a keyboard with fewer keys, typically 73 or 76, or rearranging the room. Most beginner repertoire fits on fewer keys, but advanced pieces use the full range.

Should I measure with the stand or without?

Measure the piano's width, then check the stand. Many stands are no wider than the piano itself, but X-style stands and benches can stick out. Also leave a little room on each side so your elbows are not against the wall.

Can I play a digital piano quietly in an apartment?

Yes. Every model here has a headphone output, which silences the speakers. The remaining sound is the mechanical noise of the keys, which is much quieter than an acoustic piano.
