Start by measuring your room carefully, then use digital layout tools or apps like ReimagineHome to upload photos and virtually place furniture. Experiment with varying sofa sizes, dining tables, material finishes, and style combinations to see what fits and flows best in your actual lighting. Mark furniture footprints on the floor with tape to test scale and circulation pathways. Visualizing first prevents mistakes, streamlines decision making, and helps you confidently choose furniture you love and that fits perfectly.
