What is the average distance from the floor to a window sill?

The average distance from the floor to a window sill is approximately 3 feet (1 meter). This measurement is commonly used in building codes and design standards, as it provides practical access for everyday activities such as looking out the window or closing and opening it. This height is also considered conducive to the safety and functionality of the window. Choosing this height allows for ease of use while also maintaining adequate light and ventilation within a room.

While the other heights may be found in specific contexts or styles of architecture, 3 feet is seen as the standard measurement for most residential and commercial buildings, making it the most widely accepted answer for this question.
