Grand Piano vs Baby Grand

Both types are considered horizontal pianos but vary in size, sound quality, and price. Knowing the distinctions between these two instruments will help you determine which is right for you and your needs.

A baby grand piano is typically between 4 feet 10 inches and 5 feet 6 inches long from the keyboard to the tail. It is popular for home use as it offers good sound quality and usually comes at a more affordable price than the larger grand pianos. 

Grand pianos are longer, ranging between 5 feet 7 inches and 8 feet 11 inches, which results in a richer and more expansive sound. However, they often have a higher price tag and require more space. 

If you’re serious about creating a career as a pianist or want to run a high end studio service, owning a grand piano or a baby grand is definitely a worthwhile investment.

By understanding the differences in size, sound quality, and cost between a grand piano and a baby grand piano, you can now decide which type best suits your living space, budget, and music preferences.

Grand Piano Overview

When exploring grand pianos, you will encounter various sizes and types designed for specific purposes and settings. 

The largest and most prestigious type: the concert grand piano, is commonly found in concert halls and professional recording studios. These pianos can measure up to 10 feet, and their larger size allows for longer strings and a richer sound.

The sound of a concert grand piano can easily fill an event at a large live concert venue and sounds absolutely majestic.

Concert grand pianos are part of a family of larger grand pianos, including professional or full grands, music room grands, and semi-concert grands. 

The sizes for these pianos range from 6’2″ to 9′, with music room grands typically measuring around 6 feet and semi-concert grands as large as 8 feet. These larger grand pianos are well-suited for bigger spaces like schools, churches, and larger private homes.

The size of a grand piano is an important factor to consider when selecting one for your own use. The larger the piano, the longer its strings will be, which can contribute to a more powerful and dynamic sound. The longer strings also provide improved sound projection and increased sustain, making them exceptional instruments for professional use.

Remember that the size and type of grand piano you choose will significantly impact its performance and sound and where you’ll be able to use it. 

Consider exploring baby grand pianos if you want an instrument for a smaller space. If you have ample space and want to enjoy the benefits of a richer sound, a larger grand piano could be your ideal choice.

Baby Grand Overview

As a popular home use choice, baby grands offer excellent sound quality while being more affordable and taking up less space than larger piano models.

Baby grands feature a unique horizontal string arrangement that allows for superior acoustics, making them a close sibling to the grand piano in sound quality. 

They come in various sizes, such as the petite grand, ranging from 4 feet 10 inches to 5 feet 6 inches long.

These instruments are more affordable and easier to accommodate in smaller rooms, so they are a great option when choosing a baby grand piano for your home or recording studio. They have the aesthetics and sound of a grand piano but work well with limited space and budget constraints.

While baby grands might be smaller than their full-size counterparts, they still offer an impressive musical experience. Their sound quality remains exceptional and closely matches the larger grand pianos. 

Known for their beauty and elegance, baby grand pianos can be a perfect centerpiece in any room, adding a touch of sophistication and charm to your home.

Sizes and Types

Different Grand Piano Types

Several types of grand pianos are available, and they mainly differ in size. These types are:

  • Petite Grand: The smallest type, typically around 4 feet 10 inches to 5 feet 6 inches.
  • Baby Grand: Slightly larger than the petite, measuring between 4 feet 6 inches and 5 feet 10 inches.
  • Parlor Grand: Medium-sized pianos, 5 feet 7 to 6 feet 4 inches long.
  • Semi-Grand or Ballroom: Larger than parlor grands, spanning 6 feet 5 inches to 7 feet 5 inches.
  • Concert Grand: The largest type, usually ranging from 7 feet 6 inches to 9 feet and more.

Size of the Soundboard

The soundboard is a crucial component that affects the piano’s sound quality. As you move up from the petite to the concert grand, the soundboard’s size increases, enabling a richer, amplified, and resonant sound. 

When selecting a piano, consider how the size of the soundboard influences the instrument’s overall tone and projection qualities.

Piano Sizes

Here’s a summary of the sizes for each type of grand piano:

Specific measurements might vary slightly between manufacturers.

Grand Piano vs Baby Grand: Comfort and Space Considerations

When choosing between a grand piano and a baby grand, it’s essential to consider the available space in your home and how your choice will affect your comfort while playing the instrument.

Small Spaces

A baby grand piano might suit those with limited space, such as a small living room or music room. Baby grands typically measure between 4 feet 10 inches to 5 feet 6 inches in length, allowing them to fit more easily in tighter spaces. 

Since they are smaller, baby grand pianos produce less volume and force than their larger counterparts, but they still offer a beautiful and rich sound. As a result, baby grands are often an excellent choice for those with limited space who don’t want to compromise on sound quality.

Large Spaces

A grand piano can be a stunning centerpiece for your music enjoyment if you have ample space in your home, such as a large living room. Grand pianos range between 5 feet 7 inches to 8 feet 11 inches and more, providing a fuller sound and greater resonance due to their larger size. 

While they may require more room and investment, grand pianos often deliver a more powerful and impressive musical experience.

Remember that sufficient space around the piano is crucial for the instrument’s performance and your comfort while playing. 

So, ensure there is enough room for you to move freely and for the sound to resonate properly, regardless of your chosen piano size.

Sound Quality and Range

When comparing grand and baby grand pianos, it is important to consider the differences in sound quality and range.

String Length

One of the main differences between grand and baby grand pianos is the length of the strings. In a grand piano, the strings are generally longer, which can directly affect the sound quality and dynamic range.

  • Longer strings: In a grand piano, the longer strings produce a richer, fuller sound that professional musicians often consider more desirable. These strings also offer a greater dynamic range, allowing for more expressive playing.
  • Shorter strings: Baby grand pianos have shorter strings, resulting in a slightly thinner sound quality and a reduced dynamic range compared to larger grands. However, this may still be suitable for most domestic use.

The larger soundboard in a grand piano contributes to its superior sound quality. This allows the instrument to produce a louder, more resonant sound.

Key Action

Another factor that affects a piano’s performance and sound quality is its key action. Both grand and baby grand pianos have similar key action mechanisms. However, larger grands may offer a more responsive feel due to their increased size and the longer strings.

Alternatives to Grands

In addition to grand and baby grand pianos, there are other options you can consider:

Number one

Upright Pianos

Upright pianos are commonly found in homes, schools, and rehearsal spaces due to their space-saving design. Their vertical, compact size allows you to fit them into tight spaces while offering similar tonal quality to a baby grand or grand piano. 

The sound quality and touch may not be as rich as a grand piano, but they still provide a satisfactory playing experience for a lower cost.

Number two

Vertical Pianos

Vertical pianos are similar to upright pianos, with the soundboard and strings arranged vertically. They come in various sizes, usually as spinets, consoles, studios, and professional uprights, with the smallest being the spinet. 

The larger the vertical piano, the better the sound quality, but consider the available space before deciding.

Number three

Digital Pianos

Digital pianos offer a fantastic alternative for those who need portability, space-saving, and affordability. With technological advancements, many digital pianos now accurately replicate the feel and sound of an acoustic piano, making them suitable for both practice and performance. 

Additionally, digital pianos offer a wide range of features, such as built-in metronomes, recording capabilities, and the ability to connect to computers and smart devices.

Number four

Digital Grand Pianos

Digital grand pianos are luxury versions of digital pianos that closely resemble the appearance and feel of grand or baby grand pianos. They often feature a full 88-key keyboard with weighted keys and high-quality sound samples replicated from acoustic pianos. 

While they may not provide the same resonant sound as an acoustic grand piano, digital grand pianos can be an elegant and practical option for those seeking the grand piano look without the high cost and maintenance.

Purchasing Considerations

New vs Used Pianos

When considering buying a grand piano or a baby grand piano, one major decision is buying a new or used piano. 

A new piano will give you the assurance of perfect condition, warranty, and dealer support, but it can be more expensive. 

On the other hand, the used piano market offers a wide range of options where you can find a great deal at a comparatively low price, but it might require more maintenance or repairs.

It’s important to carefully evaluate the condition and history of a used piano, as factors like soundboard quality, tuning stability, and lifespan can all be affected by the age and maintenance history of the instrument. 

If you are not entirely confident in assessing the piano yourself, consider seeking advice from a professional piano technician or tuner.

Price Range

The price range for grand pianos and baby grand pianos varies greatly depending on factors such as brand, size, condition, and location. 

New baby grand pianos can range from $3,000 to $20,000, while full-sized grand pianos can have a much higher price tag. Here are some general price ranges to consider:

  • New Baby Grand Pianos: $3,000 – $20,000
  • Used Baby Grand Pianos: $1,500 – $15,000
  • New Grand Pianos: $10,000 – $100,000+
  • Used Grand Pianos: $8,000 – $70,000+

Remember that these approximate price ranges vary based on brand, location, and specific model features. Sometimes, you might even come across free pianos offered by individuals looking to get rid of an old instrument. 

While such an offer might be tempting, thoroughly inspect the piano for any potential issues. It’s also important to factor in additional costs like moving, tuning, and potential repairs when considering the overall cost of the piano.

Maintenance and Care

Piano Tuning

To ensure the longevity and quality of your piano, it’s essential to have it tuned on a regular basis. The process is similar whether you have a grand piano or a baby grand. Piano tuners are skilled professionals who can adjust the tension of the strings to achieve the correct pitch for each note. 

It is recommended to tune your piano at least twice a year or more frequently if used heavily or in fluctuating humidity environments.

When purchasing a piano, you should also consider the cost of regular tuning. The prices can vary but typically range between $60 and $250.

Pianos can go out of tune over a long time due to various factors, such as changes in temperature, humidity, or simple string settling. 

Keeping your piano well-tuned preserves its sound quality, helps you develop your musical ear, and maintains consistency in your practice and performance.

Regular Maintenance

In addition to tuning, regular maintenance is vital for your piano’s overall health and longevity. Below are some key aspects of maintaining your grand or baby grand piano:

Number one


Keep your piano clean by dusting it regularly using a soft, lint-free cloth. Avoid harsh cleaning products, which may damage the finish or internal components.

Number two


The action, or the mechanism responsible for converting key depression into hammer movement, may require regulation over time. This involves adjusting the various parts of the action for optimal responsiveness and an even touch across the keyboard.

Number three


The felt hammers in your piano can harden and form grooves at the points of contact with the strings, leading to a harsh and undesirable tone. Consulting a professional to adjust the hardness of the hammers, a process known as voicing can refresh your piano’s sound.

Number four


Be mindful of where you place your piano. Avoid direct sunlight, heating or cooling vents, and areas with fluctuating temperatures and humidity. These factors can cause the wood to warp or the strings to go out of tune more rapidly.

By regularly giving your grand or baby grand piano the attention it requires, you can ensure it remains in top-notch condition for years to come. 

Remember to entrust any technical maintenance, such as tuning and regulation, to experienced piano tuners and technicians.

Finding the Right Piano for You

Skill Level and Goals

Consider your skill level and goals when choosing between a grand piano and a baby grand. If you are a beginner, a baby grand piano might be more suitable for you, as it offers better control and is ideal for developing necessary techniques. 

Baby grand pianos are generally more affordable, ranging from $3,000 to $20,000. As you progress in skill and look to perform in larger venues, a grand piano could become a perfect option, with prices ranging from $50,000 to $80,000.

Location and Environment

The location and environment of your new home for your piano are important factors to consider. Baby grand pianos are smaller, ranging from 4 feet 5 inches to 5 feet 5 inches long, making them ideal for tight spaces and popular for residential use. 

They fit comfortably in living rooms, music rooms, or smaller performance venues. On the other hand, grand pianos can range from 5 feet 7 inches to 8 feet 11 inches in length, requiring more space to accommodate their dimensions. 

They are better suited for larger auditoriums, concert halls, and spacious homes with dedicated music rooms.

Remember that both grand and baby grand pianos perform best in low humidity and a stable temperature environment to ensure their longevity and preservation of sound quality. Ensure your chosen space has the appropriate conditions regardless of the piano’s size.
