Nord Stage 4 88 vs 73 Key Comparison
Number of keys
The Nord Stage 4 73-Key Fully-Weighted Piano offers 73 keys, providing a compact layout that saves space on your stage or studio desk. The Nord Stage 4 88-Key Fully-Weighted Keyboard includes the full 88 keys found on an acoustic piano. This standard range allows you to play complex classical pieces or wide jazz chords without reaching beyond the edge. If your repertoire requires the complete bass-to-treble span, the 88-key model is the necessary choice. The 73-key version is ideal for players who primarily use synthesizer patches or organ sounds in the middle register.
Physical dimensions
Both models share the same width of 10.2 inches and height of 19.7 inches. This consistency means they fit into similar rack spaces or stand configurations. However, the length differs significantly. The 73-key model measures 51.2 inches in length, while the 88-key version extends to 59.8 inches. This nearly nine-inch difference affects how much table space you need. You must measure your setup carefully if space is tight. The longer body of the 88-key model accommodates the additional keys without changing the vertical profile or depth.
Weight and portability
Portability matters for gigging musicians who carry gear to venues. The Nord Stage 4 73-Key Fully-Weighted Piano weighs 37 pounds. The Nord Stage 4 88-Key Fully-Weighted Keyboard weighs 53 pounds. That is a 16-pound difference, which is substantial when lifting gear in and out of a vehicle. The lighter 73-key model is easier to handle for frequent transport. The heavier 88-key model requires more effort and possibly a helper. If you move your instrument daily, the weight advantage clearly favors the shorter keyboard.
Key action details
Both instruments feature fully weighted key actions designed for a realistic piano feel. The data explicitly notes that the 88-key model uses a triple-sensor keybed. This technology allows for faster note repetition and more precise detection of key movements, which is critical for rapid organ or harpsichord playing. The 73-key model is listed as fully weighted, but the specific triple-sensor detail is not explicitly confirmed in the provided data for this variant. For players demanding the highest level of touch response and repetition speed, the documented triple-sensor system is a technical advantage.
Form factor and usage
Both units are classified as stage pianos with a black color finish. The 73-key model provides a streamlined form factor that sits closer to the player. This can reduce arm strain during long sessions if you are primarily playing mid-range synthesizer or organ parts. The 88-key model offers the traditional stage piano footprint that matches acoustic piano ergonomics. Your choice depends on whether you prioritize a compact footprint or the standard reach of a full keyboard. Both are built for professional stage environments.
Which Stage 4 fits your needs
Traveling keyboardists needing portability
The 73-key model weighs 37 pounds and measures 51.2 inches long. This compact size and lighter weight make it easier to transport between venues. You get a fully weighted action in a smaller footprint, ideal for gigs where space and carrying weight are primary concerns.
Pianists requiring full range
The 88-key version provides the complete piano range you need for classical or solo repertoire. It features a triple-sensor keybed for fast, smooth response. While it weighs 53 pounds and is longer at 59.8 inches, the full key count and detailed sound engines justify the extra bulk.
Studio producers building complex patches
This model includes the Wave 2 Synth Engine with three independently managed synth layers. You can attenuate each layer for complex patch construction. The doubled sample memory allows for greater fidelity when adding custom instruments from the Nord Piano Library, supporting detailed sound design in a studio setting.
