Checkerboard: The most effective pattern

A checkerboard floor. The side length of the squares is twenty-five to forty centimeters, alternating two colors: black and white, cream with dark green, or pink with brick red are all acceptable; the squares are laid straight or at a forty-five-degree angle, continuously covering the entire room. Because the scale is large enough, the pattern is clear and not fragmented; because there are only two colors, it can accommodate more colors on the walls and furniture. Avoid: using fine grids with side lengths less than ten centimeters, using more than two colors for the squares, laying the grid only in a partial area, using checkerboard on both the floor and walls simultaneously.

一片棋盤格的地面。方格的邊長是二十五到四十公分,兩色交替:黑白、奶油配深綠、粉紅配磚紅都可以;方格以正向或四十五度斜向鋪設,連續覆蓋整個房間。因為尺度夠大,圖案清楚而不細碎;因為只有兩色,它可以承受牆面與家具上更多的顏色。避免:使用邊長小於十公分的細碎格、使用超過兩種顏色的格子、讓格子只鋪局部的一塊、把棋盤格同時用在地面與牆面。
