Common Challenges & Solutions
Every beginner faces obstacles. Here's how to overcome them:
⚠️
Room isn't a perfect rectangle
Solution: Divide it into rectangles. Measure each section separately, calculate each area, add them together. Or measure the largest rectangle and note 'approximately.'
⚠️
Measurements include inches, not just feet
Solution: Convert to decimal: 12 feet 6 inches = 12.5 feet (6 inches is half a foot). Or keep in inches: 12.5 ft × 10 ft = 12.5 × 120 inches = 1,500 square inches. Then divide by 144 to get square feet.
