Compare new Yamaha, Churairat-reconditioned Yamaha, new CLASSIC and new Kawai grand pianos by size and budget.
Short answer
Grand pianos range from compact 151–153 cm models suitable for homes to 227–229 cm instruments for players who want greater power and tonal depth. Based on prices available in July 2026, a new CLASSIC GPX-152 starts at around THB 200,000, Churairat-reconditioned Yamaha grand pianos start at THB 295,000, while new Yamaha and Kawai models range from the THB 400,000s to more than THB 1.6 million.
Start with the piano's length, not only its model name or price
A grand piano's length is related to string length, soundboard area, key feel, sound projection and the musical detail a player can experience. This guide uses current Yamaha grand piano lengths as a reference, then places Churairat-reconditioned Yamaha, new CLASSIC and new Kawai models in similar size groups to help you compare options by budget, available space and long-term playing goals.
Important: Pianos of similar length are not necessarily equivalent. Series, country of manufacture, materials, construction and design philosophy may differ. Use this table as an initial guide to size and budget, then play and inspect the actual instrument before deciding.
Which grand piano size suits each type of use?
An entry size for homes or large condominiums with sufficient room and a suitable delivery route.
A popular range for homes and studios because the longer strings and larger soundboard provide a noticeable step up in tonal potential.
For players who want greater power and tonal depth. Lid clearance and the entire delivery route should be assessed carefully.

Churairat-reconditioned Yamaha: compare by size and play the actual piano
Churairat-reconditioned Yamaha grand pianos are available in sizes from approximately 173 to 227 cm, usually at significantly lower prices than new grand pianos. Every instrument must pass the Churairat Recondition Standard, with more than 50 inspection and reconditioning points covering the structure, soundboard, action, hammers, exterior and interior components, tonal balancing and tuning.
Because every reconditioned piano has a different year, history, original condition and reconditioning record, listening to the actual piano and testing its key weight and pedals are essential parts of the decision.

Prices depend on the model, number of pedals, condition and details of the actual instrument. The Churairat-reconditioned Yamaha grand pianos listed here include a Lifetime Buy-Back Guarantee, with the buy-back value assessed according to the piano's condition and market value at the time of assessment.

What is the difference between two-pedal and three-pedal grand pianos?
Some more affordable G-2, G-3 and G-5 instruments have two pedals. They still provide the two principal sound-control pedals: soft and sustain. Three-pedal models add a sostenuto pedal in the centre.
2 pedals
- Soft / Una Corda: Shifts the action slightly sideways, softening the sound and changing its tonal character.
- Sustain / Damper: Lifts the dampers from the strings so notes continue to resonate after the keys are released.
3 pedals
- Includes the same soft and sustain pedals as a two-pedal model.
- Sostenuto: Sustains only the notes or chord held before the pedal is pressed, while later notes behave normally.
Which grand piano should you consider at each budget?
The new 152 cm CLASSIC GPX-152 suits buyers looking for an entry-size new grand piano. Confirm the current price, colour and promotion before ordering.
Churairat-reconditioned Yamaha G-2 and G-3 models become available in this range. They suit buyers who value a longer Yamaha grand, but the actual condition and reconditioning standard should be considered alongside price.
Depending on space and playing level, buyers can consider reconditioned G-3, G-5, C-3 and C-5 models. Test tonal balance and key weight, and assess the delivery route before deciding.
This budget provides a wider choice of new Yamaha C Series and Kawai GL/GX Series models. Compare tonal character, size, after-sales service and the actual playing experience.
What should you ask and inspect before buying a grand piano?
Measure the piano area, lid clearance, entrances, lifts, stairs and turning points.
Check the actual length of the piano because similar model numbers can differ by series and year.
Ask what work was completed, who was responsible and whether the process follows a verifiable standard.
Listen to the tonal balance and test key weight, response and pedals on the actual instrument.
Review the warranty, tuning, after-sales support and buy-back terms.

Churairat Lifetime Buy-Back Guarantee
Choosing a grand piano should not be based only on the day of purchase. It is also worth considering what happens if you later want to change models, move to a longer instrument or stop using the piano.
Lifetime Buy-Back Guarantee
Churairat grand pianos include the Churairat Lifetime Buy-Back Guarantee, subject to company terms and conditions. The buy-back value is assessed according to the piano's condition and market conditions at the time of assessment; it is not a guarantee of a fixed buy-back price.
Frequently asked questions
Is a longer grand piano always better?
For new pianos in comparable series, a longer instrument often has greater tonal potential because of its longer strings and larger soundboard.
For ordinary used pianos without a verified standard, length alone is not enough to decide because condition, use and maintenance vary from one instrument to another.
For Churairat-reconditioned Yamaha pianos, a longer model that has passed the Churairat Recondition Standard and belongs to a comparable series generally offers greater potential, but it must still suit the room.
Are the G-3 and C-3 the same size?
Do not decide from the model number alone. Length and specifications can differ slightly by series and year, so always check the dimensions of the actual piano you are considering.
Why should I play a reconditioned grand piano before buying it?
Every instrument has a different history, original condition and reconditioning record. Listening to its tonal balance and testing its key weight and response in person gives you a clearer basis for comparison than photographs or model names alone.
