Buying a digital piano for the start – what really matters? As a piano teacher I have advised beginners on instrument purchases for over 30 years, and most buy either too little (unweighted keys) or too much (an expensive model with features they never use).
This guide names the six criteria that actually count, a realistic price recommendation, and the most common buying mistakes – so you buy right once and enjoy the instrument for years.
The 6 key buying criteria
1. 88 weighted keys
The keyboard is the heart of the instrument. Look for 88 keys (like a real piano) with a weighted action. Only that feels like a piano – and only that trains the control your hands need on any instrument later. Models with unweighted or semi-weighted keys save money but teach the wrong feel.
2. Touch sensitivity
Volume must respond to your touch: soft when you press gently, loud when you play strongly. That is the basis of expression and dynamics – without touch sensitivity you never properly learn an essential piano skill.
3. A good piano sound
You will hear this sound every day. Modern digital pianos (from about $450) are nearly indistinguishable from acoustic ones to the human ear. Test before buying: the sound should be warm and natural, without harsh highs.
4. Polyphony
Polyphony (number of simultaneously sounding notes) should be at least 64, ideally 128. That way full chords with the pedal stay clean, without cut-off notes.
5. Headphone output and volume
A good headphone output is gold: you can practice quietly anytime, without disturbing family or neighbors. For children in the junior program this is key to regular practice.
6. Pedal
A sustain pedal is standard. Many entry models include a simple pedal, higher-end models a three-pedal system. For a start, a sustain pedal is all you need.
Price guidance: what is really worth it?
| Price range | What you get | Best for |
|---|---|---|
| under $300 | Unweighted keys, simple sound | Testing only, not recommended for learning |
| $450–800 | Weighted keys, good sound, headphones, pedal | The sweet spot for beginners (adults and kids) |
| $800–1300 | Better action, three-pedal, more sounds | Ambitious beginners planning classical |
| over $1300 | Premium action, near-acoustic sound | Advanced players, students |
For most beginners the $450–800 class is the right entry: weighted keys, good sound, and durability – the instrument will accompany you for years until you consciously upgrade.
The most common buying mistakes
- Focusing only on the number of sounds: 500 built-in sounds do not replace a weighted action. Keyboard and touch count, not the sound list.
- Confusing a keyboard with a digital piano: A keyboard with 61 light keys is a different instrument. For learning piano you need 88 weighted keys.
- Buying used without testing: Digital pianos last long, but test the action and all keys – including soft tones – before you buy.
- Underestimating the space: Measure where the instrument will stand before buying. A digital piano with a stand needs as much space as a keyboard with a stand, but is heavier.
Digital piano, keyboard, or acoustic piano?
You do not need an acoustic piano to start – a digital piano with weighted keys is entirely sufficient and has practical advantages: no tuning, headphones, compact design. If you are deciding between piano and keyboard, read our comparison Piano or Keyboard for Beginners.
"I saved up and bought a digital piano for $650. After a year I am glad I did not listen to the cheap keyboard recommended to me in the store – the weighted keys make all the difference when practicing."
Digital piano for children
For children (junior program, from about age 6) a digital piano is ideal: with headphones and adjustable volume, kids practice without disturbing the household. Important is an action that fits the child – for very young children a slightly lighter action can make sense, but not unweighted. Fingering and posture should be right from the start.
After the purchase: start right
With the right instrument, the next step is the most important: a structured start that builds progressively. Keyboard orientation, chords, accompaniment patterns, and ear training – exactly what you learn step by step instead of drifting through YouTube videos.

Which digital piano is good for beginners?
A digital piano with 88 weighted keys, hammer or graded action, and a good piano sound. From about $450–800 there are models that last for years and correctly convey the piano feel.
How much does a good digital piano cost?
For a decent entry-level digital piano with weighted keys, budget $450–800. Below that you usually get unweighted keys that do not convey the piano feel correctly.
Are 88 keys important?
Yes. Piano repertoire uses the full range. With 88 keys (like a real piano) you are ready for any piece, and the feel matches an acoustic piano.
Do beginners need an acoustic piano?
No. A digital piano with weighted keys is entirely sufficient to start – it sounds almost like an acoustic piano today, never needs tuning, and can be played with headphones.
Can a child start on a digital piano?
Yes. For children (junior program from about age 6) a digital piano is ideal – with headphones and adjustable volume, kids can practice even when others are at home.
