Which Steinway Fits Your Home? Model Guide by Room Size

Which Steinway Fits Your Home? A Room-by-Room Guide to the S, M, O, A, and B

The most common question we hear in our Natick and Burlington showrooms isn't about price or vintage. It's simpler, and more important: "Which Steinway is right for my home?"

It's the right place to start. A grand piano is a piece of architecture as much as an instrument — the wrong size will either overwhelm a room or leave you wishing for more sound. The good news is that Steinway made a model for nearly every space, and after 45 years of matching pianos to homes across New England, the fit is usually clearer than people expect.

Here's how the five grand models compare, from smallest to largest — with the rooms and players each one suits best.

Steinway Model S — 5'1" · the apartment and condo grand

The Model S is Steinway's smallest grand, designed for spaces where a larger instrument simply won't fit — apartments, condominiums, smaller studies. It delivers an authentic Steinway touch and tone in a remarkably compact footprint. If you love the idea of a true Steinway but your room is tight, the S is where the conversation begins.

Best for: small rooms, first-time grand owners, players who prize the Steinway name and feel over maximum volume.

Steinway Model M — 5'7" · the living-room favorite

The Model M is the piano most families choose. At 5'7", it produces enough warmth and bass to satisfy a serious player while fitting comfortably into a standard living room. For a child advancing through lessons or an adult returning to the instrument, the M is the sweet spot of size, sound, and value — which is exactly why it's our most requested model.

Best for: family homes, students progressing past the beginner stage, most living rooms.

Steinway Model O — 5'10¾" · the living-room grand with real depth

The Model O is the largest of the "small grands," and the extra length shows. Longer strings and a bigger soundboard give it a fuller, more resonant bass than the M — noticeably more instrument, still sized to fit almost any home. Pre-war Model O pianos are especially prized by collectors for their singing tone.

Best for: larger living rooms and music rooms, players who want depth without stepping up to a 6-foot piano.

Steinway Model A — 6'2" · the parlor grand

The Model A is where the sound opens up. At 6'2", it offers genuine concert-quality tone and a commanding bass, yet fits rooms that can't accommodate the larger B. For a dedicated music room or a spacious living room, the A is a versatile, deeply satisfying choice — a serious instrument that still lives gracefully at home.

Best for: music rooms, advanced and semi-professional players, larger homes.

Steinway Model B — 6'10" · "the perfect piano"

The Model B is the most sought-after grand Steinway makes, and many pianists consider it the finest all-around piano in the world. At 6'10" it delivers a full, rich bass, a singing tenor, and a brilliant treble that larger rooms can carry beautifully. It's the instrument of choice for serious home performers and many professionals — a piano you grow into for life, not out of.

Best for: large music rooms and great rooms, advanced pianists, anyone buying their last piano first.

A quick way to decide

As a rule of thumb: measure your room's longest wall and picture the piano occupying roughly a third of it, lid open. If your space is under ~14 feet, look at the S or M. Fourteen to eighteen feet opens up the O and A. Beyond that — or in a true music room — the B rewards you every time you sit down.

But dimensions only tell half the story. The other half is tone — and no two vintage Steinways sound quite alike, which is the quiet advantage of buying a carefully selected pre-owned instrument. Every piano in our collection is personally evaluated by Roger, so the M you play in Natick may have a completely different voice from the next one, and part of our job is helping you find the one that speaks to you.

Come hear the difference

The surest way to choose is to play a few, side by side, in one afternoon. That's exactly what our showrooms are for — bring two or three pieces of music and let the pianos make the decision for you.
