To measure accurately for small home office furniture, first identify the exact corner or niche you want to use. Measure the width, height, and depth of the space with a tape measure, noting any obstacles like outlets or trim. Leave about five centimeters of clearance for easy movement and chair placement. Sketch the layout to scale or use room visualization tools online by inputting these measurements. Accurate measuring ensures your desk or shelves fit perfectly without crowding, making your small home office both functional and comfortable from day one.
