How Much Does a Piano Weigh?

Depending on a model, the weight of your piano can vary in a broad range. However, it is always a massive piece of furniture regardless of its type. The lightest pianos are keyboards, digital, spinet, console, and studio pianos, while the heaviest models are upright and grand pianos.

Keep in mind that the average upright piano usually weighs anywhere from 200 to 1000 pounds (90 – 455 kg), while the grand piano is from 400 to 1200 pounds (180 – 545 kg) heavy. To determine the precise measures of your instrument, you should consider its type first. Then, look at the tables I have made for you and check how much does a piano weigh.

The Average Piano Weigh

A piano schoolboy Adrian Mann from New Zealand, designed the largest piano in the world. After four years of head work, he made a grandiose 18.7 feet (5.7 m) long instrument that weighs 3,100 pounds (1.4 tons).

Besides this unique instrument, most pianos are built in the standard weight. In most cases, piano designers change the piano’s materials and shape but rarely deviate from the standard sizes.

The same goes for the most expensive piano in the world. This Crystal Piano, sold at an auction for $3.22 million, designed a Canadian manufacturer Heintzman & Co.

The largest commercial piano nowadays is the Fazioli F308, which weighs impressive 1,260 pounds (570 kg). Luckily, you don’t need such a massive instrument. Even more, you have numerous lighter models at your disposal, like:

Electronic keyboards

This small and portable model with 61 keys is the lightest of all pianos. It typically weighs 20 pounds (9 kg).

Digital pianos

This instrument has a full set of 88 keys. You can find portable models weighing approximately 20 pounds (9 kg) and larger digital console pianos weighing up to 100 pounds (45 kg).

Vertical piano

Piano type Weight Height
Spinet 200 to 400 pounds (90 – 180 kg) 36 to 40 inches (0.9 – 1 m)
Console 350 to 450 pounds (160 – 205 kg) 40 to 43 inches (1 – 1.1 m)
Studio 400 to 500 pounds (180 – 230 kg) 44 to 48 inches (1.1 – 1.2 m)
Upright 500 to 1000 pounds (230 – 455 kg) 48 to 60 inches (1.2 – 1.5 m)

What Causes a Piano to Be So Heavy?

The combination of different, mostly heavy materials makes the piano one of the most massive musical instruments ever designed. Keep in mind that up to 70% of each model’s overall weight makes the heavyweight cast iron plate. Let’s see.

Piano casing

Since it is made from many thin, mutually glued layers of specially selected wood, the piano body is highly heavy. The casing thickness dramatically affects the acoustics balancing and sound of the piano since a thicker case produces darker tones.

For upright pianos, the height is crucial since the vertically positioned casing makes a more magnificent sound. Unfortunately, it implies more wood and, consequently, a more massive piano. The positive thing is that some parts, including the lid and the pedal mechanism’s cover, are removable. That makes moving the instrument more comfortable.

Cast-iron plate

This piece, which holds the tension the strings create, is the heaviest piano part. It weighs from 50 to 70% of the overall piano weight. For example, a cast-iron plate of a baby grand piano of 600 pounds (270 kg) weighing approximately 300 to 375 pounds (135 – 170 kg).

Metal strings

The average piano has 220 to 230 strings made of steel or copper thick about 1/30 inch (0.85 mm), while wound bass strings are thicker and measure around 1/3 inch (8.5 mm).

Each of them carries about 168 pounds (76 kg) of tension, which means that the total tension of the whole instrument is approximately 36,000 to 40,000 pounds (18 – 20 tons). However, some grand piano models can reach an impressive 60,000 pounds (30 tons). Keep in mind that that doesn’t entirely contribute to the overall weight of this instrument.


Since they are made of wool and other fibers, piano hammers don’t weigh much individually. However, there are many of them, so their contribution to the instrument’s overall weight is not negligible.

Piano legs

There is no standard size, shape, or design of piano legs, but they depend on the manufacturer. Even though they are mostly constructed of wood, some models have heavy metal wheels. Keep in mind that pianos created before the 1950s had more dense legs.

Piano lid

Since the piano lid is made of solid wood to protect the inside components efficiently, it is cumbersome. It has two parts that can weigh from 20 to 45 pounds (9 – 20.5 kg) and even more, depending on the piano size.


Soundboard, made of textured spruce wood layers and placed underneath the cast-iron harp, is the most delicate piano part. It is not so heavy but still contributes to the instrument’s massiveness since it spans its entire length.

Piano keys

Most contemporary pianos have 88 keys made of solid wood body and plastic covering. Keep in mind that vintage ivory keys weigh more than modern ones.


The piano is the largest and undoubtedly the heaviest musical instrument in the world. While the most standard pianos are of average weight, it will mostly depend on the particular model.

For instance, a Kawai GL-10 and Yamaha baby grand pianos won’t weigh the same, although both are of the same size. The final number is different because of the wood type and the metal used for making hammers and strings.
