An 88-key piano covers the full piano range, while a 76-key board leaves out notes at the low and high ends. The missing notes sit at the far low and high ends of the range, so a 76-key board suits players who want a shorter keyboard. All the picks below have 88 keys with weighted hammer action.
What 88 keys cover
88 keys cover the full piano range from the lowest note to the highest note. A full piano has 88 keys, so an 88-key digital piano matches the range of the acoustic piano. A 76-key board covers the same range except for the lowest and highest notes. Players who need notes at the far ends of the range need 88 keys.
What 76 keys leave out
A 76-key board leaves out notes at the low end and the high end of the piano range. Those notes sit at the far ends of the range, outside the keys a 76-key board covers. A 76-key board still plays the same middle range as an 88-key piano. Check the range of the music you play against the keys the board has.
Weighted keys and hammer action
Weighted keys and hammer action describe how the keys respond under the fingers, not how many keys the board has. All the picks below have 88 weighted keys with hammer action. The Donner lists graded hammer action, the GLARRY lists full weighted hammer action, and the Ktaxon lists semi-weighted keys. A 76-key board can also have weighted keys, so the key count and the key action are separate choices.
Choose by range, size and weight
An 88-key piano is wider than a 76-key board, so check the space where the piano will sit before you buy. The Donner weighs 46.5 lb, the STRICH weighs 47 lb and the GLARRY weighs 55.1 lb, so the models below differ in weight even though all have 88 keys. The STRICH lists a stand in the box, the GLARRY lists triple pedals, and the Ktaxon lists a bench and a three-pedal unit. Pick the key count for the range you need, then compare the weight and what comes in the box.

Frequently asked questions
Do I need 88 keys or is 76 enough?
It depends on the range you need. An 88-key piano covers the full piano range, while a 76-key board leaves out the lowest and highest notes. Players who need notes at the far ends of the range need 88 keys.
Are 76-key pianos smaller than 88-key pianos?
A 76-key board is shorter than an 88-key piano because it has fewer keys, so it takes less space on a stand. The keys are the same size, and the layout is the same. Check the width of the space where the piano will sit.
Do 76-key keyboards have weighted keys?
Some do and some do not, since the key count and the key action are separate choices. All the picks below have 88 weighted keys with hammer action. Check the action the board lists before you buy, and decide the key count for the range you need.
