Comparing Portable Keyboards & Digital Pianos

Learn About the Different Types of Electric Keyboards


Sometimes, these two terms are used interchangeably. While the term “electric keyboard” can be used to describe both, there are definite differences between portable keyboards and digital pianos. These differences come down to size, features, and cost:

Body & Keyboard Size

  • Portable keyboards are just that, portable. They usually weigh less than 20 lbs. and have a smaller range; 61 and 49-key models are most common. Optional keyboard stands may be offered with the instrument at an additional cost, but they can be played table-top, and are also easily storable.

  • Digital pianos are not unstorable, but they’re typically meant to sit atop a custom-fitted stand. They can weigh from 25-60 lbs., and usually come with 61, 76, or 88 keys.

Keys & Sensitivity

  • Portable keyboard keys are notoriously light and plasticy compared to acoustic or digital pianos. Touch-sensitivity – which allows for a change in volume depending on how hard a key is pressed – may not be a feature; and polyphony – the ability to play many notes at the same time – is sometimes limited.

  • Digital piano keys are usually full-length, and feel more like an acoustic. Some models even mimic the feel of a piano incredibly well with keys that are heavier to the touch in the bass octaves – a feature known as “graded hammer-action.” Polyphony may range from 32 to 64-notes (sometimes more), and touch-sensitivity is standard and may even be adjustable.

Voices & Song Banks

  • Portable keyboards come with many, sometimes hundreds, of rhythms, built-in songs, and voices (which often include several varieties of pianos, organs, woodwinds, bells, and percussion; as well as wonderfully random sound-effects). It should be noted, however, that their voices can sound phony and “electric,” and speaker volume may be limited.

  • Digital pianos may only offer a few voices, and might not contain any songs or rhythms at all. The voices offered usually sound pretty genuine (depending on brand and quality), and tend to be the staples: Grand piano, harpsichord, strings, and jazz or pipe organ. Abridged sample songs may be included to offer a preview of the voices in action.

Price Comparison

  • A portable instrument carries a lighter price tag, weighing in between $100 to $500 depending on keyboard size, brand, and features. The Casio WPK-200 is a 76-key option that costs around $200.

  • A digital set of keys can be found for as low as $300, but many fall in the $500-$1500 range. The most expensive digital piano – which is actually a grand piano/digital hybrid – will only cost you a mere $20,000!!

Bottom Line

Digital pianos are preferred as cost- and space-effective alternatives to an acoustic piano. Portable keyboards are best-suited for beginner or practice instruments, or just for fun.
