Yamaha gives each of these pianos its own stand: the L-125 for the P-125, the L-100 for the P-145 and the L-200 for the P-225. It publishes the key height for none of them. If you’re shopping for a Yamaha P-125 bench, or one for a P-145 or P-225, the number you need is one you measure yourself.
Yamaha lists heights for the L-100 and L-200, not the L-125, and describes no adjustment on any of them. Two US retailers put the keys at 28.75 in on the L-200. Run that through our calculator’s formula and the seat a player needs runs from about 20.7 in at 5’0″ down to about 18.5 in at 6’4″. Pair a bench that has one height with that stand and it suits one player height, give or take.
If your keys aren’t measured yet or two people share the piano, the Hydraulic bench (159.99$) reaches every seat height this guide works out, anywhere from 18 to 24 in (my picks).
Which Yamaha stand fits the P-125, P-145 and P-225 (and which pedal unit)
This is how Yamaha’s own spec pages and owner’s manuals pair them, checked in October 2026.
| Model | P-125 / P-125a | P-145 / P-145BT | P-225 |
|---|---|---|---|
| Yamaha stand | L-125 | L-100 | L-200 |
| Stand height | Not published | 648 mm (25.5 in) | 648 mm (25.5 in) |
| Body height | 166 mm | 129 mm | 129 mm |
| Weight | 11.8 kg | 11.1 kg | 11.5 kg |
| 3-pedal unit | LP-1 | LP-5A | LP-1 |
The LP-1 needs the L-125 or L-200 under it, the LP-5A the L-100. Yamaha’s US site marks the LP-5A discontinued.
Two naming traps. Yamaha Australia lists the P-125 as discontinued, and the US now sells the P-125a with the same body figures; its manual names the same L-125. In the US you’ll find the P-145BT, in the UK the P-145: same figures, both on the L-100.
How tall is a P-145 or P-225 on its stand, and where do the keys sit?
Yamaha does print one height with the stand. On the P-145BT spec page, which sets it beside the P-225, both measure 744 mm (29-5/16 in) “with optional stand”. That’s the top of the piano. The keys sit lower, and Yamaha doesn’t say by how much.
The numbers don’t stack
The L-100 and L-200 are 648 mm tall and the piano body is 129 mm. That adds up to 777 mm, yet Yamaha’s figure for the pair is 744 mm. For the P-125 there’s even less to go on: Yamaha gives no L-125 dimensions at all, and the one retailer figure I found is a 26 in tier height.
The closest thing to a key height is a retailer line: George’s Music and Vintage King both list the keys at 28.75 in on the L-200. Use it as a starting point, then measure your own.
- Set the piano up on the stand and floor it will live on.
- With the tape’s end on the floor, read it where it meets the top front edge of a white key.
- Take a second reading near the other end of the keyboard. If the two differ, the floor slopes: work from the middle of the two and write that number down.
L-125, L-100 or L-200 vs an X-stand: what changes for the keys
L-series stand
Heights are in the table above. Yamaha says the L-125 holds the keyboard “at the optimal height for seated playing” and describes no adjustment for any of the three.
X or Z stand
These are height-adjustable, so the key height moves with the stand: set it where you’ll play, then take the same two readings. The P-125’s cabinet is 166 mm tall, 37 mm (about 1.5 in) more than a P-145 or P-225. A Piano World poster who uses an adjustable K&M Omega wrote: “The p125 is a thick DP and on its lowest setting it’s still a couple inches higher” than a U1 upright.
Desk
Whatever the desk, put the piano on it and take the same two readings as above.
My notes on benches for digital keyboards in general cover the wider choice. Below, six benches are charted against the L-200 zone and against keys at 30.5 in, an example of the higher reading you may get on an X-stand or a desk.

Start with the presets in our piano bench height calculator: the upright one assumes keys at about 73 cm (28.7 in), the digital-on-a-stand one about 72 cm (28.3 in). It takes about 0.135 times your height off the key top, so a taller player sits lower.
A 28.75 in key top sits on the upright preset, so use that one. If your keys measure something else, work out how far they sit from 28.7 in and shift the calculator’s seat figure by that much, up if they’re higher, down if lower: at 30.5 in, add about 1.8 in. Once you have the seat figure, the chart above shows which benches reach it.
Worked example
Take a 5’7″ player. With keys at 28.75 in (the L-200 retailer figure) the seat comes to about 19.7 in; at a measured 30.5 in, about 21.5 in.
At 6’4″ and a 28.75 in key top, the math asks for about 18.5 in, lower than the BB1, the BC-108 or our Back Support bench will go. I cover the rest of that problem in piano benches for tall people. Check your height and posture at the keys before settling on it.
Yamaha BB1, BC-108 or PKBB1 vs an adjustable bench
Yamaha sells these three benches but labels none of them for the P-125, P-145 or P-225, so here they are against the chart’s two zones. Where the table says “Partly”, check your own number against the seat range.
| Bench | Seat range (travel) | L-200 stand zone 18.5-20.7 in | Keys at 30.5 in 20.2-22.4 in |
|---|---|---|---|
| Yamaha BB1 | 19.5 in (one height listed) | Partly | No |
| Yamaha BC-108 | 19.68 in, no adjustment | Partly | No |
| Yamaha PKBB1 | 17.5-19.5 in (2 in) | Partly | No |
| Benchoom Classic | 18.5-22.2 in (3.7 in) | Yes | Partly |
| Benchoom Back Support | 19.7-24 in (4.3 in) | Partly | Yes |
| Benchoom Hydraulic | 18-24 in (6 in) | Yes | Yes |

- BB1: Alamo Music bundles it with a P-125a and an L-125. Yamaha’s listing gives one seat height, 19.5 in, with nothing about adjusting it. By this math it suits a player of about 5’8″ to 5’9″ at a 28.75 in key top.
- BC-108: Yamaha’s spec reads “Height Adjustment: No” at 19.68 in, which is right for about a 5’7″ player.
- PKBB1: a portable X-style bench, 17.5 to 19.5 in. In the L-200 zone it suits the same 5’8″ to 5’9″ player as the BB1, and anyone taller; at 30.5 in it’s too low for everyone.
Best bench for a Yamaha P-125, P-145 or P-225: my picks
Price first. If the BB1 from your bundle puts your forearms level with the keys, keep your money. On an L-100 or L-200 with the keys near 28.75 in, the Classic (99.99$) covers the whole zone.
The Hydraulic (159.99$) is the one I’d buy if you’re not sure of your number yet, P-125 owners on the L-125 included. On an X-stand or a desk your keys may sit higher than on the L-200; at 30.5 in, for example, the Classic stops short for players under about 5’2″. The Hydraulic reaches 24 in, and if the piano moves later, you turn the knob to the new number, as long as it falls between 18 and 24 in.
When the number isn’t settled: Hydraulic Height Piano Bench
Six inches of travel, 18 to 24 in, the most of any bench on the chart, our Back Support included. The side knob does the adjusting; there’s no lever and you need no tools.
A steel frame rated for 500 lb sits under the 27.5 by 12 in seat.
Back Support for long sessions
An adjustable lumbar back you can lean on between pieces, rated for 300 lb. Its seat won’t go below 19.7 in, so in the L-200 zone it stops suiting players above about 5’7″. At 30.5 in it reaches the whole zone.
Classic, the budget pick
The Classic’s 22 in wide seat adjusts with two knobs, one at each end. It covers the L-200 zone for players 5’0″ to about 6’4″, and at 30.5 in it fits players about 5’2″ and taller.

LP-1, LP-5A and FC3A pedals: where to put the bench
Each of the three pianos ships with a footswitch, and Yamaha doesn’t name the model. The FC3A is the optional foot pedal; on the P-125a, Yamaha says it adds half pedaling. The LP-1 and LP-5A pedal units each mount only on their L-series stand (see the table above).
With your right heel down at the pedal, slide the bench until the front of the stand is clear of your knees. You can pull a loose footswitch toward you; an LP-1 or LP-5A stays put, so you move the bench. On an X-stand or a desk neither unit can be mounted, which leaves the footswitch or an FC3A.
FAQ
What stand fits the Yamaha P-125?
The L-125. Yamaha’s P-125a manual names it for the P-125a too, and the LP-1 three-pedal unit needs it. Yamaha publishes no dimensions for it, and its Canadian accessory list doesn’t show it, so check availability before you plan around it.
Is the L-100 or L-200 stand height adjustable?
Yamaha lists one height for each, 648 mm (25.5 in), and describes no adjustment. Plan on the bench taking up any difference.
How tall is a P-225 or P-145 on its Yamaha stand?
744 mm (29-5/16 in) to the top of the piano, not the keys, per Yamaha. It gives no key height. Retailers list 28.75 in for the keys on the L-200; take your own reading before buying.
Does Yamaha make a bench for the P-125?
None is labelled for it. Yamaha sells benches such as the BB1, PKBB1 and BC-108, but none of them names the P-125, P-145 or P-225, so compare their seat ranges with your number.
Do the P-145 and P-145BT use the same stand?
Yes. Yamaha lists the L-100 for both, with the same 744 mm height on the stand, and lists the LP-5A pedal unit for both.
Picking a Yamaha P-125 bench, or a seat for the P-145 and P-225, starts from the key top on the stand you play on. On an L-200 at 28.75 in, the Classic covers players 5’0″ to about 6’4″, and a player around 5’8″ can keep the BB1. Anything less settled points back to the Hydraulic.
The piano bench height calculator gives you the seat number in about a minute.
