Record the window features
Measure the sill and note handles, trim, outlets and any equipment beneath the window. Photograph the area straight on and from the side. A floor plan alone does not show whether the sofa back will overlap a feature you need to reach.
Test the curtain movement
Open and close the actual curtains or blinds while representing the sofa position with boxes. Fabric needs somewhere to fall and gather. Avoid buying a lower sofa solely to match the sill if the depth still interferes with the window covering.
Plan access without habitual furniture moving
Decide how you will clean the sill and operate the window under normal circumstances. A layout that requires pulling out a heavy sofa every week can become frustrating. Keep any required access or manufacturer clearances for nearby equipment in the decision.
Compare the daylight effect
Sit in the proposed position at the times you normally use the room. Look at screen reflections and the lighting on a book. These observations can change which direction the sofa should face without requiring a larger piece or an entirely different style.
For example, a low-back sofa might sit neatly below the sill but trap floor-length curtains behind it. Moving the sofa forward could solve that issue only if the remaining floor layout still works.
