Size reference
Standard grand piano dimensions.
A grand piano is sized by its LENGTH (tail to keyboard), but the case WIDTH is nearly constant at ~58–60 in on every size — it is fixed by the 88-key keyboard — so the width is the door constraint, not the length. Petite/baby grand: 4’11″–5’3″ long (59–63 in), ~500–600 lb. Medium/parlor grand: 5’7″–6’4″ (67–76 in), ~600–750 lb. Semi-concert: 7 ft (84 in), ~900 lb. Concert grand: 9 ft (108 in), 990–1,200+ lb. Height on its legs with the lid closed is ~39–41 in.
Run a check
Will it fit?
On moving day
Moving tips.
- 01Always move a grand on a padded piano board (skid) on its straight side — never upright on its legs, which can snap under the lateral load.
- 02Remove the two front legs and the pedal lyre before lifting; bag and label the hardware so reassembly tuning is faster.
- 03Plan the route around the ~5 ft case width, not the length — measure your narrowest doorway, hallway turn, and elevator diagonal against 58–60 in.
- 04A grand needs re-tuning after any move; schedule a tuner for a week or two after it settles in the new room and climate.
Measure smart
What to measure.
Four numbers decide nearly every fit check. Get these right and the rest follows.
- 01Your grand piano's width, height, and depth at their widest points — including handles, feet, and any fixed trim. A standard grand piano runs about 60" deep, but compact and oversized versions vary by several inches, so measure yours rather than trusting the label.
- 02The smallest face of the grand piano and its diagonal. Many pieces only clear a tight opening when tilted, and that turns on the diagonal, not the flat width.
- 03Every opening on the route, not just the destination room — the door, the hallway and any turn, the stair width, and the elevator. "Through a Door" is the check people run most for a grand piano, but the tightest point on the whole path is what decides the move.
- 04The grand piano's weight, especially for solid-wood pieces, so you know how many people and what equipment the move needs.
Don't make these
Common mistakes.
Most “it didn't fit” stories trace back to one of these oversights.
- ⚠Measuring the room the grand piano is headed for but forgetting the doorway, hallway turn, or stair landing it has to pass through first.
- ⚠Ignoring the diagonal. A grand piano that looks too wide for a door often clears it tilted — but only if you measured the diagonal, not the flat face.
- ⚠Leaving legs, doors, drawers, or cushions on. Removing them often saves the few inches that decide the fit for a grand piano.
- ⚠Assuming a published size matches your exact grand piano. Apartment, compact, and oversized models differ by several inches.
Frequently asked
Questions we keep getting.
What are the standard dimensions of a grand piano?
Grand pianos are categorized by length. A baby grand is 4’11″ to 5’3″ long (59–63 in), a medium or parlor grand is 5’7″ to 6’4″ (67–76 in), a semi-concert grand is about 7 ft (84 in), and a full concert grand is 9 ft (108 in). The width is ~58–60 in and the height on its legs is ~39–41 in across every size.
01What measurement decides if a grand piano fits through a door?
The case width, not the length. Because the keyboard is always 88 keys, the width stays at ~58–60 in on a baby grand and a concert grand alike. When you move a grand it is tipped onto its straight side (legs off) onto a padded piano board, so the opening only has to clear the case width of ~5 ft — wider than a standard 32 in door, which is why grands almost always go through double doors, patio sliders, or are tipped through on a board at an angle.
02How much does a grand piano weigh?
A baby grand weighs about 500–600 lb, a medium grand 600–750 lb, a 7-ft semi-concert around 900 lb, and a 9-ft concert grand 990 to over 1,200 lb. The weight is concentrated on three legs, so once it is on a piano board and dolly the load is spread, but you still need three or more movers.
03How do professionals move a grand piano?
They lower the lid, remove the music desk, then detach the two front legs and the pedal lyre while the piano is supported on its straight side against a padded piano board (a wooden skid). The piano travels on its side on the board, strapped to a four-wheel dolly. This narrows the move profile to the case width and protects the soundboard and legs, which are the most damage-prone parts.
04Can a grand piano go upstairs or in an elevator?
Sometimes, but it depends. On its board a grand is ~5 ft long and 2–2.5 ft thick — it can clear a wide straight staircase but rarely a tight switchback or spiral. For elevators, the board length (case width, ~5 ft) must fit the cab diagonal. Given the weight, confirm the elevator load rating; many residential cabs are rated 2,500 lb and handle a grand plus movers, but verify before booking.
