How Much Does a Piano Weigh?
Most acoustic pianos weigh between 300 and 1,000 pounds. A console upright is about 300 to 400 lbs, a full upright 500 to 800 lbs, a baby grand 500 to 600 lbs, and a 9-foot concert grand can reach 1,300 lbs. A digital piano weighs just 25 to 150 lbs.
Piano weight by type
| Type | Weight (lbs) | Weight (kg) |
|---|---|---|
| Portable / stage digital piano | 25 - 40 lbs | 11 - 18 kg |
| Console digital piano (with stand) | 80 - 150 lbs | 36 - 68 kg |
| Spinet upright (36-40 in) | 200 - 300 lbs | 90 - 135 kg |
| Console upright (40-44 in) | 300 - 400 lbs | 135 - 180 kg |
| Studio upright (45-48 in) | 400 - 500 lbs | 180 - 225 kg |
| Full / professional upright (48-52 in) | 500 - 800 lbs | 225 - 360 kg |
| Baby grand (5 - 5.5 ft) | 500 - 600 lbs | 225 - 270 kg |
| Medium grand (5.5 - 6.5 ft) | 600 - 750 lbs | 270 - 340 kg |
| Grand (6.5 - 7.5 ft) | 750 - 900 lbs | 340 - 410 kg |
| Concert grand (9 ft) | 900 - 1,300 lbs | 410 - 590 kg |
Where the weight comes from
A piano is heavy for a structural reason. The strings of a full-size piano pull with roughly 18 to 20 tons of combined tension, and the cast-iron plate that resists that force is the single heaviest part. Add the hardwood rim, the soundboard, the action with its thousands of parts, and the keybed, and even a modest upright easily passes 300 pounds. Longer grands weigh more because they use a larger plate and a longer, heavier rim.
Why weight matters when you buy or move
Weight is the reason moving an acoustic piano is a professional job, not a two-person favor. It also affects where you can put one: a heavy grand concentrates its load on three legs, so upper floors in older buildings deserve a second thought. If you move often or live in an apartment, the low weight of a digital piano is a real practical advantage. For the full cost picture, see how to move a piano and how much a piano costs.
Frequently asked questions
Why are pianos so heavy?
Most of the weight is the cast-iron plate (the frame) and the wooden structure that hold the strings under tension. A full piano carries roughly 18 to 20 tons of combined string tension, so the frame has to be massive to resist it.
How many people does it take to move a piano?
An upright usually needs at least three or four people; a grand needs a professional crew with a piano board, straps, and a dolly. Because of the weight and the risk of injury or damage, moving any acoustic piano is a job for professional piano movers.
Can a piano go upstairs or on an upper floor?
Yes, but stairs add substantial cost and risk, and the floor must support the load. A grand can exceed 1,000 lbs concentrated on three legs, so for older buildings it is worth confirming the floor rating.
How much does a digital piano weigh?
A portable stage piano weighs about 25 to 40 lbs, and a furniture-style console digital with its stand is roughly 80 to 150 lbs. That is a fraction of any acoustic, which is one reason digitals are popular for apartments and frequent movers.

Weights are typical ranges by cabinet style and size; individual models vary with plate design, rim thickness, and era. Manufacturer specification sheets list the exact shipping weight for a given model.
