MUIC & ACOUTIC – PIANO & KEYBOARD CALCULATOR
Organ Pipe Length
A precise tool.
What is the Organ Pipe Length & How does it work?
The length of an organ pipe is directly related to the frequency of the note it produces. For a closed-end pipe, the fundamental frequency ( f ) is given by:
f = frac{v}{4L}
v = speed of sound in air, L = length of the pipe
This formula assumes that the pipe is closed at one end and open at the other. The speed of sound in air can vary based on temperature, but it is approximately 343 meters per second at room temperature.

Frequently Asked Questions
How do I calculate the length of an organ pipe for a specific note?
To find the length, rearrange the formula to L = v / (4f), where v is the speed of sound and f is the frequency of the note.
What is the fundamental frequency of a closed-end organ pipe with a length of 0.5 meters?
Using the formula f = v / (4L), with v = 343 m/s, the frequency is approximately 1715 Hz.
How does temperature affect the calculation of organ pipe length?
Temperature affects the speed of sound, which in turn affects the calculated length. Use the appropriate speed of sound for the given temperature.
Can this formula be used for open-end pipes as well?
No, this formula is specifically for closed-end pipes. Open-end pipes have a different relationship between frequency and length.
What is the significance of the ‘closed’ end in an organ pipe?
The closed end creates a node (no displacement) at that point, which affects the standing wave pattern and thus the frequency produced.
How do I convert the length from meters to centimeters for this calculation?
Multiply the length in meters by 100 to convert it to centimeters. The formula remains the same; just ensure all units are consistent.
