How to Measure Your Room for Carpet
Even with a carpet calculator, you need accurate room measurements. Follow these steps:
Step 1: Measure the Length
Use a tape measure to record the longest wall of the room. Note it in meters or feet.
Step 2: Measure the Width
Measure the shortest wall. If the room is irregular, divide it into sections and measure each.
Step 3: Consider Obstacles
Subtract areas for built-in furniture, fireplaces, or cabinets if the carpet won’t go there.

Most professionals recommend 5–10% extra to account for mistakes and pattern matching.
