Summary
Highlights
The height of your coffee table should match the height of your sofa's seat cushion. The length should be about 3/5ths the size of your sofa. If it's too small, double up or use nested end tables.
Decorate with multiple shades of an accent color to add variation and depth to your home. Use deeper and lighter tones in paint, tiles, pillows, curtains, rugs, and furniture.
Hang wall art so the midpoint is 57 to 60 inches off the floor. This applies to single pieces and gallery walls, ensuring comfortable eye-level viewing and integration with the furniture.
Create contrast between walls and trim (baseboards, doors, window trim) using either color or sheen. If monochromatic, use a glossier finish on the trim. This will highlight the architectural elements.
Hang curtain rods at least 4 to 6 inches above the window frame. For a grander look, extend the rod closer to the ceiling to make the room feel larger.
End tables should be 1 to 2 inches lower than the sofa's armrest. Nightstands should align with the top of the mattress. For double beds, nightstands should be 17-20 inches wide; queen beds, 21-30 inches wide; king beds, 31+ inches wide.
Rugs should extend 12-18 inches off the bed on either side and off the footboard. Use at least a 6x9 rug for a double bed, 8x10 for a queen bed, and 9x12 or 10x14 for a king bed. Layer rugs if the existing one is too small.
Incorporate ambient, accent, and task lighting. Ambient lighting (ceiling lights) should be complemented by accent lighting (table lamps, floor lamps, sconces) and task lighting (reading lamps, desk lights) for functionality.
