This guide is based on manufacturer specifications, published information and buyer feedback. We do not claim hands-on testing and we do not give music teaching advice. Always follow the instructions that come with your own instrument.
Key count is one of the first choices you will make. Here is what each size means in practice.
What each size offers
| Keys | Typical use | Notes |
|---|---|---|
| 61 | Beginners, songwriting, synth-style playing | Compact and cheap; limited range for piano pieces |
| 76 | Gigging and stage keyboards | A compromise between size and range |
| 88 | Learning and playing piano repertoire | Full range; matches an acoustic piano |
Who can start on 61 keys?
Complete beginners learning simple songs, children trying out the instrument and people mainly interested in synth sounds can start on a smaller keyboard. Check with any teacher you plan to use, because many ask for a full-size weighted keyboard.
Why most pianists choose 88
Classical and many popular pieces use the full range. If you plan to progress, an 88-key instrument avoids needing to replace it later. See the best 88-key weighted keyboards.
Key action matters too
More keys with poor action may feel worse than fewer keys with a better action. Read weighted vs semi-weighted keys.
Space and portability
Compact 88-key digital pianos exist, so you often do not need to give up the full range to save space. See portable digital pianos and digital pianos for apartments.
Examples by player type
- Absolute beginner on a tight budget: a 61-key keyboard can be a first step, but consider a path to 88 keys.
- Student with lessons: 88 weighted keys are the common recommendation.
- Singer-songwriter or gigging player: 76 or 88 keys, depending on portability.
- Producer: smaller controller keyboards can suffice for sequencing.
Do not forget the pedal
Regardless of key count, a sustain pedal makes a big difference to expressive playing. See sustain pedals.
