How to measure pianos and keyboards

 Updated on 25th April 2023

Grand Piano & Baby Grand

The biggest physical differentiator between Grand pianos or baby grands is their length. They range from 5' all the way to 8.5'. There are also several concert grand models that are even longer in length.

Traditionally, Piano makers have found that longer strings tend to increase instrument power, reverberation and produces the desired tonal characteristics, which gave rise to the popularity of grand pianos. 

Before measuring your piano, please make sure to close the lids and keep the music rest down for a more accurate measurement.

Length: From the front of keyboard to the center of the tail at the back [ Longest points with the lids closed]

Width: From right to left over the music shelf where the music rest is located [ Longest points with the lids closed ]

Height: From the floor to the tallest point of the piano [Music rest folded down or kept under lid]

*Please note that the lids usually give slight extensions to the piano, it isimportant to account for the full length and width of the grand piano.

Vertical and Upright Piano

Upright pianos, also known as vertical pianos, features a compact frame and vertical strings. They are popular models purchased for home use due to their size and affordable pricing. 

The sizes of these pianos also vary among different manufacturers even though their shape stays relatively similar. Most standard sized upright pianos are around 150-154cm [ 4 feet and 11.055 inches ] in width while junior sized uprights are approximately 148-149cm [ 4 feet and 10.26772 inches ]

Our upright piano covers are designed such that it is able to fit almost all the different models from individual manufacturers. This is due to the overhang design, which also allows easy access to the keyboards. The overhang design has a natural and minimalist approach which provides greater ease and efficiency for the piano user.

Width: Measure from left to right over the top of the piano [ Longest points with the lids closed ]

Depth: Measure from front of keyboard to back of piano [ Longest points with lids closed ]

Height: From the floor to the tallest point of the piano, usually on the piano lid [ Tallest point with lids closed ]

*Please note that Piano width is often mistaken with the term "piano length" for upright or vertical pianos. Certain electric or digital pianos, such as the Yamaha Clavinova Series, are shaped to look similar to an upright piano. In these cases, they are measured the same way as an Upright piano.

Digital Piano & Keyboards [ 76 - 88 keys ]

The Digital pianos are the smallest in size as they do not require strings to be installed. Portable and full of features, these pianos are highly popular with beginners and experts alike. 

The main difference between a digital piano and a keyboard is their action and size of the keys. Digital pianos are made to resemble the feel of an acoustic piano and they usually come with 88 keys, which is the usual number of keys found on an upright or grand piano.
