What Is a Baby Grand Piano? How Long Is It and What Kind of Home Does It Suit?
Understand small grand piano sizes before buying, with model examples and approximate prices as of July 2026.
Quick Answer
The term Baby Grand has no universally fixed length. Grand pianos measuring approximately 140–153 cm are often called Petite Grands or Small Grands, although some brands may call them Baby Grands. Always compare the actual length of each model rather than relying on the category name alone.
A Baby Grand Piano Is a Compact Grand Piano for the Home
Baby Grand Piano is a common name for a compact grand piano suited to the home, but it is not a technical size standard. Manufacturers may use different model names and size categories. This guide therefore focuses on actual lengths and real models to explain what a smaller grand offers and how to choose one.
1. How Long Is a Baby Grand Piano?
There is no single worldwide standard for these size categories, so use them as a starting point for comparison.
| Common size category | Approximate length | What to know |
|---|---|---|
| Petite / Small Grand | Approx. 140–153 cm | The most compact grand piano category, with a true grand action and cabinet form. It suits homes moving up to a grand piano, although some brands may also call models in this range Baby Grands. |
| Baby Grand | Approx. 153–170 cm | A term used for small to compact grand pianos. Its range may overlap with Petite or Small Grand. As length increases, the strings are generally longer and the soundboard larger. |
| Medium-size Grand | Approx. 173 cm and above | Many models at this length enter the medium-size grand category, although some markets may still use Baby Grand as a marketing term. |
Similar Sizes May Have Different Names
A grand piano measuring 151–153 cm may be called a Petite Grand, Small Grand, or Baby Grand depending on the manufacturer and market. Begin by comparing the actual length, then consider sound quality, key touch, and whether the instrument suits your available space.
Petite / Small Grand, or Baby Grand for some brands
The range commonly called Baby Grand
The medium-size grand category begins for many models

3. What Does a Smaller Grand Offer, and What Are Its Limitations?
Advantages of a Baby Grand
- It provides a grand piano action, which is arranged horizontally and responds differently from an upright piano action.
- At around 150–160 cm long, it is easier to place in a home than models measuring 180–200 cm or more.
- It suits buyers who want the presence and open-lid sound projection of a grand piano without using as much floor space.
What to Compare with Longer Models
A longer grand piano generally has longer strings and a larger soundboard, which can provide greater power and tonal dimension. However, a longer instrument is not automatically the best choice for everyone. Listen to the tonal balance, test the key weight, inspect the actual instrument, and consider how well it matches the size of the room.
4. What Kind of Home Suits a Baby Grand Piano?
A Baby Grand suits a home with a reception room, living room, or music room that has a dedicated placement area and where the piano can become part of the room's atmosphere. Do not consider only the instrument's length; allow for the space around it as well.
| Area to check | What to measure or consider |
|---|---|
| Placement area | The piano's length and width, together with the piano bench position and the space needed for the player. |
| Opening the lid | The lid-opening direction and open-lid height. The lid must not strike a wall, light fitting, or furniture. |
| Access route | Doors, corridors, lifts, stairs, and turning points, assessed using the actual dimensions of the chosen model. |
| Floor and room conditions | Floor strength, protection from direct sunlight and humidity, and the position of air-conditioning outlets. |
| Positioning | Allow clearance from walls and position the piano for good sound dispersion, while leaving enough access for servicing. |
The Required Floor Area Is More Than the Piano's Length
In addition to the Baby Grand's length, allow for its width, bench position, playing space, lid-opening direction, and a walkway around the instrument. Before buying, check the delivery route from doors and turning points to stairs and lifts.
Recommendation: Send a floor plan or photographs of the room to the team for an assessment before purchasing. This helps identify a size that is balanced with the room and can actually be installed.
5. Should You Choose a New Baby Grand or a Reconditioned Yamaha?
When You Want a New Grand with a Manageable Budget
The GPX-152 is a new 152 cm grand piano from Churairat Music's CLASSIC brand, priced at around THB 200,000. It suits buyers who want a new instrument and would like to begin using a true grand piano action.
When You Want a Longer Yamaha Grand at a Similar Budget
A Churairat Reconditioned Yamaha grand piano, such as the approximately 173 cm G-2, is an option for buyers who prioritise a longer instrument. Compare each individual piano, verify that it has passed the Churairat Recondition Standard, and test its tonal balance, key weight, and pedals in person.
For Your First Step Up to a Grand Piano, You Can Start with a Baby Grand
First-time grand piano owners may begin with a Baby Grand to learn from everyday use whether it suits their playing style, room size, and home placement. Over time, it becomes clearer whether a 152–161 cm instrument is sufficient or whether moving to a longer grand would be worthwhile.
A Buy-Back Guarantee Makes the First Decision Easier
Grand pianos from Churairat Music include the Churairat Lifetime Buy-Back Guarantee. If you later wish to move to a longer grand piano, Churairat Music provides a defined buy-back option subject to company terms and an assessment of the piano's condition and market conditions on the assessment date. This removes the uncertainty and difficulty of trying to sell the piano privately.
When Choosing a New Yamaha or New Kawai
Compare actual length, budget, warranty, and the opportunity to try the piano. Models in the 151–166 cm range clearly represent entry-size grands through Baby Grands. For models measuring 173 cm and above, examine the available floor area and intended use more carefully.
6. Frequently Asked Questions
Is a Baby Grand Different from a Grand Piano?
A Baby Grand and a Grand Piano use the same type of grand piano action because a Baby Grand is itself a Grand Piano. The main differences are the length of the instrument and strings, and the size of the soundboard.
Is a Baby Grand Suitable for a Condominium?
It may be suitable if the condominium has enough placement space and an accessible delivery route. Ask a specialist to assess the doors, lift, corridors, and intended position before deciding.
Is a Small Baby Grand Adequate for Serious Study?
Yes, it can be sufficient for study and home playing if the piano is in good condition and properly maintained. Consider the quality of the individual instrument and its suitability for your needs, not length alone.
Does a Baby Grand Require Different Care from an Upright Piano?
Tuning, humidity control, protection from sunlight, and regular inspection remain important. However, a grand piano has a different structure and action from an upright, so it should be serviced by a technician experienced with grand pianos.
What Should You Ask When Buying a Reconditioned Baby Grand?
Ask whether the piano has been reconditioned, who performed the work, which areas were serviced, and whether you trust that process. Also check the warranty terms, after-sales service, and buy-back guarantee.
Can You Change to a Longer Grand Piano Later?
Yes. Grand pianos from Churairat Music include the Churairat Lifetime Buy-Back Guarantee, providing a buy-back option if you later decide to move to a longer model that better suits your needs.
Conclusion
A Baby Grand is a good starting point for anyone who wants the experience of a Grand Piano at home. Compare the actual length and decide based on space, placement, budget, and an in-person trial. The GPX-152 from Churairat Music's CLASSIC brand makes it possible to begin with a new Grand Piano at a manageable budget, while the Churairat Lifetime Buy-Back Guarantee provides an option to move to a longer Grand Piano in the future.
