A piano is a beautiful instrument, but it would certainly break your bathroom scale.
Lots of people wonder how heavy these behemoths really are.
You probably know they're heavy, but how heavy, exactly?
It's beneficial to know things like this if you're planning to transport a piano or you're an aspiring pianist looking to buy one.
In this article, I’ll cover the weight of every piano type, including many popular piano models.
Different Piano Types
The amount of piano types in the world is endless, but I’ll cover the most popular ones. Each of them varies in size and weight class. Here are the two main piano types on the market right now:
Within these types, there are several subcategories. For example, the category of upright pianos includes Spinet, Console, and Studio pianos. Technically, these pianos are classified as "vertical pianos," but most people call them upright. There's the Petite, Baby, Medium, Professional, Semi-Concert, and Concert Grand Pianos in the Grand Piano category. I'll go through the weights of each of these types, starting from smallest to largest.
Spinets are the smallest of vertical pianos. They are generally 3' to 3'4" tall and weigh 200-400 lbs. Because of their small, lightweight nature, Spinets are the easiest type of vertical piano to transport.
Popular Spinet Piano
One of the most popular Spinet pianos types is Baldwin Acrosonic. There are several models in the Acrosonic series, and they all weigh between 300 and 400 lbs.
Console pianos are a bit larger than Spinets and weigh 350 to 450 lbs. They're also slightly taller, measuring 3'4" to 3'7".
Popular Console Piano
The Yamaha MX500S is a popular console piano. It's 3'6" tall and weighs approximately 410 lbs.

Upright pianos have a much wider weight range than other vertical pianos. These instruments can weigh 500 to 1,000 lbs and be 4' to 5' tall. If you're going to move an upright piano, it's essential to have a moving plan beforehand. A lack of a plan could lead to injury, damage to the piano, and even the piano's destruction. There have been many piano accidents involving a piano falling off the back of a truck.

Why are Pianos So Heavy?
Pianos are made up of countless heavy materials that account for their big weights. Here are some significant pieces that contribute to their weight:
The cast-iron plate is the biggest contributor to a piano's weight. This simple piece can make up 50% to 70% of the entire weight of the piano. On a baby grand piano, it can weigh up to 375 lbs. Heavy cast-iron plates are necessary because they house all of the strings' tension. On the Steinway D Concert Grand Piano, the cast-iron plate weighs an estimated 600-700 lbs.
The piano case, or body, comprises countless layers of wood. Piano manufacturers tend to use higher-quality wood because of increased resonance. In turn, the piano's weight increases. A thicker case produces a darker tone and vice versa.
If you've ever lifted the lid on a grand piano, you know how heavy it is. Piano lids can be anywhere from 20 to 60 lbs, depending on the size of the instrument. They're made from solid wood to protect the internal mechanisms of the piano.
Soundboards are wooden pieces that resonate the piano's sound. Without them, the volume of a piano would be more comparable to a guitar. They aren't extremely heavy, but they still contribute to the overall weight.
Easy Way to Move a Piano
Moving a piano can be intimidating at first, but it not as difficult as it seems. Here are a few helpful tips:
Plan your route before trying to move the piano. Improvisation can be good in some of life's situations, but this isn't one of them. It's best if you know where you're going to avoid damaging the piano.
Pianos have two main lids: the keyboard and the cabinet lid. Make sure you secure both of them down before moving the piano. One of the best ways to do this is by wrapping blankets around the instrument. To keep the blankets in place, use strong tape, like packaging tape. If you're moving a grand piano, the cover should work fine.
Finally, it's time to move the piano with a dolly, carefully. It's surprising how well a small dolly can lug a large piano. It's great to have another person at the dolly's front or back to make sure it doesn't tip over.
