Carpet tiles, also known as carpet squares or modular carpeting, are easily installed side-by-side to create a smooth, carpeted floor that looks just like wall-to-wall carpeting.
Step 3: Snap chalk lines to find the center of the room. To install carpet tiles, you must first find the center of the room. To do so, first snap a chalk line from one corner of the room to the opposite corner. Repeat for the opposing corners. The center of the room is where the lines cross. Use a tape measure to find and mark the centers of each of the four walls. Then snap two more chalk lines from the opposing centers of the four walls, starting with the longer side of the room first. The cross-pattern that is made by the chalk lines will be in the center of the room. The resulting cross-pattern indicates the room's center.
Follow all the safety instructions included with your new carpet tiles. Handle the utility knife used for trimming carpet tiles with great care and always cut away from your body.
