The composition is balanced by the arrangement of furniture and decorative elements within the room. The painting is executed in oil on canvas, a medium that allows for rich color application and texture. Matisse's brushwork is loose and expressive, contributing to the overall sense of movement and light. The dimensions of the work are approximately 65 x 81 cm, making it a medium-sized piece.

Viewers can appreciate the interplay of light and shadow, which enhances the depth of the scene.

La fenêtre ouverte is a prime example of his style during the early 20th century, reflecting his fascination with the interplay of interior and exterior spaces. An interesting fact about this work is that it was created during a period when Matisse was experimenting with color theory and the emotional impact of color.
