Recessed Lighting Placement Calculator
Installing recessed lighting can dramatically improve the appearance and functionality of any room, but achieving a balanced layout requires proper planning. Lights that are too close together can create excessive brightness and waste energy, while fixtures placed too far apart may leave dark spots and uneven illumination. Our Recessed Lighting Placement Calculator helps you determine the recommended spacing and placement of recessed lights based on your room dimensions, ceiling height, and light size.
Whether you're designing lighting for a living room, kitchen, bedroom, office, basement, or commercial space, this calculator provides quick and practical estimates. It calculates the recommended spacing between lights, total number of fixtures, rows, columns, distance from walls, and overall room coverage, making it easier to create a professional-looking lighting layout before installation.
